Matt Crystalus-Uchiha

Matthews Crystalus, later known as Matt Crystalus-Uchiha is a super crystalian, last son of Buster Crystalus and Sapphire Uchiha, which means, he's the younger brother of Louis Crystalus-Uchiha, Hootch Crystalus-Uchiha and Derick Crystalus-Uchiha, his age is 13 and he is the chosen warrior to wield the Eternal Blade, Galaxia.

Background Matt is the last son of Buster Crystalus and Sapphire Uchiha, also, younger brother of Louis, Hootch and Gama. His earthling name was Matthews Oak. He had a deep interest on the skies and all the secrets beyond it, such that, as a young kid, his dream was to become an airplane pilot, this dream changed when he met a strange man once he came back from school so he followed this man with his (back then) friend, Hootch. After talking to the strange man, they awaken memories of their home planet, Crystalia and are determined to return to their home. Matt returns home and talks with his parents about the whole story, after talking them into it, Matt convinces them that he can go to Crystalia and live a new like despite being only 12, Matt gets ready to leave biding his parents farewell and thanking them for everything they did for him, he then meets with Hootch and a Strange Lady, who through an unknown ability, teleported both to Crystalia.

Personality

Matt has a kind personality, being that he is only a kid, he shows interest to new things and enjoys having fun, his purity sometimes is mistaken for stupidity as he turns out to be really easy going sometimes, upon taunting, he tends to find a way to take a revenge against the one that taunted him showing his portion of mischievousness since he loves pranks, he can't hear someone calling him to a challenge as he fastly agrees on taking part of it, either that, or he resists it until he is taunted.Matt is also a gamer and also likes to read and watch creppy stuff, such as haunted movies and creppypastas(even though he seems to be scared of them).

He tends to care about his friends at the point of taking damage for them or fighting an enemy much stronger than himself, he develops a brotherly relationship with Alec Samuel Cruz at the point of calling him his "younger brother", he can't see anyone as a rival, but rather, as a friend, in contrast to Takeda Solidor, as he thinks of Matt as some kind of rival, same way with Gawain Shun.

His love relationship is turned to Amy Siren Crystak, sister of princess Ami Crystak and next to the royalty order, though she is seen as a princess by many, Matt treats her as a regular girl, much to Amy's surprise, which instantly turns her attention to him, after being rescued by Matt and his friends from Itachi's Heavenly City of Pain, her love for him grows as she looks at him feeling that he is some sort of protector. Matt can be somewhat cocky and arrogant sometimes, as he skips formal introductions by a simple "Hey", apparently irritating Derick or even Louis sometimes.

Matt also stated that he doesn't care about "power ups" as long as he has enough power to defeat his enemies and protect those who are important to him, his deep desire is becoming a "Warrior of Harmony" and he vowed that whenever he fought someone which hopes of victory would be zero, he wouldn't cry, stating that he would only cry for something "worth it", showing how determined he is. Still, even sometimes acting like an adult, Matt is still a kid, so he acts like one most of the time, specially when around his brothers and friends making even Derick question his age compared to Alec's(which is one year younger).Matt has his fair share of pride as he cannot accept defeat that easily.

Hootch states that he may have inherited that from their father, Buster, which may have also contributed with the Uchiha Clan pride, coming from their mother. As Matt is kind-hearted, Louis believes that he still hasn't developed a crystalian personality, which tends to be more arrogant and cold sometimes.

Abilities and Forms While still a kid, Matt has shown to have talent while facing enemies be it alone or with support, Louis himself did not expect him to go "so far". Matt was able to escape Takeda's arrows and Harm's strong blows put togheter before knocking both out, his power made him able to defend and counter blows from the many soldiers Solarius and Lunius sent against him, he cut many down, evading attack until he was able to reach Solarius. His abillity as a blade wielder are able to keep up with Louis' as he stated he grew in power as he was able to keep up with his speed and counter his attacks. Matt is also shown to be able to control 2 Eternal blades by Dual Wield, completely changing his fighting style into attacking from different directions with both blades. During his first battles, Matt was simply a reckless wielder which ran against the enemy, targeting vital points as shown during his first fight with Derick when he simply ran at Derick aiming for the neck(which had no result), he used to rely on his signature skill, Sword Beam to end the battle as fast as he could, constantly wasting energy against the enemy, using powerful and large beams which result in a powerful explosion. As time passed, Matt developed a battle personality consisting into observing the enemy and attack when he is vulnerable, or he adapts his fighting style to countering instead of attacking directly as shown with his fight against Louis in Heavenly City of Pain where he pushed him to a single mistake and attempted to attack Itachi during this only mistake. His Aura level without Galaxia was enough to cut Derick's arm and release a powerful Sword Beam from a simple blade, something that should be impossible to someone with his power level, after the attack he fell on his knees but apparently still had enough energy to continue fighting. His Aura increases once he awakens the super form with Galaxia's power, allowing him to use primary crystalian abilities, such as flying, using Chaos-based abilities and increasing his agility, allowing him to dodge incredibly fast attacks.

Hand-to-Hand combat Matt shows enough proficiency to keep up with Derick while fighting disarmed against him, Derick says he was going lightly against Matt, but he recognized his power and ability stating that the Crystalus blood runs inside his veins.

Swordsmanship As wielder of Galaxia, Matt developed ability while wielding a blade, adapting it to his battle style, he attacks when the enemy is vulnerable constantly using his blade in regular position, whenever he acts recklessly, he holds his blade backwards, using is as a kunai.

Blade Fusion Matt seems to be the only one capable of fusing Eternal Blades and mantaining their form, as shown against Louis, he fuses both Galaxia and Zeipo, forming the God Blade, Void Breaker in order to keep pace against Dark Galaxia's darkness power and Louis' personal ability. He was also able to fuse Galaxia with Aqolo, creating the God Blade, Deep Wave, though he was not able to mantain it's form for so long, because, as stated by Takeda, natural energy is different from inner energy(Light and Darkness) and difficult to mantain without propper training.

Sharingan Similar to an Uchiha, Matt awoke his sharingan with only one tomoe during his fight with Louis' clone, as he teamed up with Alec to beat it. During the many fights of Heavenly City of Pain, he awoke his sharingan to Full state(3 tomoes) apparently being the youngest to awaken his Kekkei Genkai.

Super Form
Super Form was the first form achieved by Matt when he took Galaxia from the altar, it was automatically activated by Galaxia's power. Matt eventually learned how to control this form perfectly after the battle in Heavenly City of Pain.

Hyper Form
Was awakened during the fight with Louis, at first, Matt could only reach this level by wielding Void Breaker, there were other ways of reaching this form such as the blessing of Rei Truvon.

Master Form
Master form was achieved briefly during Matt's fight with Chaos, it was dismissed after the fight. It is unknown if due to his Soul Fusion ability, Matt can still enter this form.

History

Welcome to Crystalia Arc Upon getting to Crystalia, Matt and Hootch start looking around the city until they get their attention pulled to a man in a tall building which asked the gates to be opened, and inviting them inside. The man reveals himself as Buster Crystalus, local hero of Crystalia amazing both. Buster provides them a place to stay, school education according to their ages and battle training as part of the Megabusters squad. Matt meets with the same strange man that was able to walk over the energy cables after disappearing completely as Hootch called him a Super Crystalian, or, a Crystalian with "super powers" to which the Strange Man replies as correct before appearing again behind them and waving a black sword against them, Hootch acts fastly and defends both of them with a training sword, Matt pushes Hootch out of the way in order to escape from the slash that broke the blade easily. The man introduced himself as Louis, namely "ItachiRJ", Matt remembered that he was a Warrior of Harmony as introduced by a poster around the city, Louis welcomed them to Crystalia and vanished. Matt decided to go home and check on books in the library trying to search any family records as he suspected that Buster was hiding something something from them, until he came across the book called "Galamon, the Creator" where he learned about the existance of the Eternal Blades, after that he is surprised by Buster who directly asked him he he wished "super powers" which he gladly replied that he did want them, with his answer, Buster teleported them to the Megabuster Base so they could train.

During the fight, Buster attacks as Matt dodges every blow, Buster then decides to show him the Sword Beam, Matt is target by the attack but dodges it sucessfully also amazed by the strength of the attack. Buster then pauses the fight and asks Matt to go with him observe Hootch's fight against Cielana, a buster, after that, the four go to the medical bay for treatment, Buster then says he'll test Matt with his best Buster, nicknamed Gama, who appears as soon as his name is said.

Gama mocks Matt by his height and power level which is remarked by Hootch as "Not cool" to which he replied that no one ever said he was cool, they then leave to Training Room S, Gama takes Matt on without a weapon eventually taunting him and kicking him to the wall, an enraged Matt activates for an instant an incomplete Sharingan as his energy grows and gives Gama a cut to the arm which he seems to be surprised, following, Matt sent a powerful Sword Beam against Gama, who escapes the attack but seems surprised by the powerful wave, Matt falls to his knees and is knocked out by Gama.

Matt woke up at home with Hootch, Buster and Gama around him, Matt gets up fully restored, Buster says he is leaving with Gama, but Hootch asks about the sword in the altar behind the house they are currectly living in. Buster answers that it's the Eternal Blade, Galaxia, after telling them about the legend, Hootch says he wants to try pulling the sword, which Matt also says he wants to try it.

Hootch tries pulling the sword as it didn't move giving place for Matt to try, as Gama silently mocked him, Matt pulls Galaxia from the altar as it came out, surprising both Gama and Buster as Matt slowly entered Super form, Gama upon seeing this is ready to leave infuriated since he was not the chosen. Matt is taken inside the library for further education about Chaos Energy and its benefits, after explanation, Matt teleports both him and Buster back to the yard through "Chaos Control", where Buster stopped Gama from unleashing a devastating power against Hootch, who had challenged him to a fight, as both leave, Matt says that he will be blonde for a while, to which Hootch replied that "it's a great hair color".

Eternal Blades Arc
Matt, along with Hootch and Gama are given the mission to search for the rest of the Eternal Blades, Matt during his search meets Takeda Solidor and Gawain Shun(commonly known as Harm), after knowing both better he discovers that Takeda is a "Quincy", a special kind of archer, and Harm is an Eternal Blade chosen as well, Matt challenges Harm only to be defeated by him, Takeda states that he has never seem someone so desperated to win as Matt was before Harm took Galaxia from him.

After talking to Buster and realizing that Galaxia would never choose another one and replace him, Matt challenges both Takeda and Harm again, with Takeda saying that he should learn when to accept defeat and understand he'd never beat his speed, Matt surprises him by surpassing his speed and avoiding his arrows before hitting him with one single punch that knocked the Quincy out.

Harm himself got surprised but kept on not accepting him as a crystalian as they fought, stating that it's impossible for someone that is not a full crystalian to awake the Super form, to which Matt replies he is right as he sees himself more like a human than a crystalian before defeating him with a Sword Beam, in the aftermatch, Matt extends his hands to both Takeda and Harm who finally realize and respect his strength as the 3 start walking togheter.

Before Power Level 0(Zero)
Matt, Hootch and Gama are given the mission to follow Itachi into the lands of Chaos. he discovers that Gama's real name is Derick, as they travel, Matt awakens his perception powers as he helps finding the real path after losing track of Itachi, which lead to the Eternal Blade, Zeipo whose chosen wielder was Hootch. Itachi shows up shortly after Hootch claimed the blade and engaged them in battle threatening to reveal a secret to both Hootch and Matt, to which Gama disagrees, ignoring him, Itachi reveals to them that he is the first son of Buster and Sapphire, as well as their older brother, surprising both Matt and Hootch.

Matt gets trapped inside Itachi's Tsukuyomi and engages Hootch and Gama(wielding Zeipo) in battle nearly overpowering both easily, however, before the final blow, Matt breaks through his genjutsu, making Itachi's sharingan bleed, after falling on his knees, Itachi is forced to retreat due to the pain, saying that he will return, after that, Matt faints.

Power Level 0(Zero)
Matt is challenged by Hootch to a race to the Crystalian Moon, as he says he've heard that the moon sustains life, Matt initially says no, but upon being taunted, he accepts the challenge which made both brothers fly at such speed that stopping was impossible, with the result of breaking the moon in half.

Matt shows regret over what happened blaming it on Hootch, Buster comes and takes both Galaxia and Zeipo, forbidding them of using their powers for 2 days in a row, assigning Gama to keep an eye on them, Matt questions about Gama never being around as he replies he also lives in the house they live, as if he is not around, he's at the base.

Matt then gets ready to leave and watch a movie with Takeda Solidor and Gawain Shun, however, Gama forbids him. After introducing both to Gama, he challenges them to a fight, resulting in an amazing, yet insufficient performance of both Harm and Takeda, surprising even Matt as he witnessed both being defeated by Gama.

Matt asks him for a go to which Gama replies he's too tired to try now, only to be mocked by Matt who pushes him against the floor and flees hiding from Derick.

Later as he promised, Derick trains with Matt with regular blades, where Matt shows maestry with his heavy blade, disarming Gama with a fast move, as they make a deal, Matt attacks him with heavy slashes and kicks, alternating between both, Gama, unaffected points to the blades as they are broken, with Matt accepting defeat he says he invited Amy to their house and begs Derick as part of their deal not to embarass him to which he replies with a simple "maybe", Matt begs again and Derick answers that he was kidding and that he should learn to know when he is kidding.

One day later, Amy, Ranpha and Ciel visit the house where they watch a horror movie with the boys, as the rain falls outside, after the movie, they speak about themselves with Amy revealing she is not actually "The" princess and explains her relationship with princess Ami to them. The girls ask them to leave so they can talk about something important, Matt leaves reluctant as Gama reveals that he can hear them but won't tell, but since he was feeling nice, he was taking Matt to an amusement park stating that he may not seem like it, but he does love him, to which Matt blushes and thanks him.

With their punishment over, Buster sends the 3 boys to a mission of finding and recovering the Eternal Blade, Tangekyo in the planet Thun'Dun as they get involved in some kind of King Arthur situation since they have to stay in a line to try and pull the blade, after sometime, Derick claims the blade which follows with Louis' appearance in Thun'Dun. As he claims that Buster died in the afternoon, Matt, enraged, attacks Louis, only to be countered by him, Louis invites the 3 to Heavenly City of Pain in order to save Amy, if Matt actually cared about her life and vanishes.

The Painful Path
Determined to save Amy, Matt is the first one to suggest taking the Painful Path. As he enters the gates of the path to the skies, he is surprised as strange warriors form from no where, the soldiers didn't seem to be crystalians or even alive as Matt cuts through them instantly reaching the exit, however, he was blocked by the Warrior of Armageddon, Solarius who stops Matt and sends him back at the entrance, Matt resisted and went through the warriors and attacks Solarius who is forced to take his Chaos Blade, Sol. Matt attacks his blade as Solarius attacks at the same time, however, Galaxia goes through his blade and Sol hits Matt's chest sending him against the floor.

Solarius explained the ability as "Ethereal Shift" when near the Chaos Blade, Luna, confusing Matt for a second before the other Warrior of Armageddon appeared, his name was Lunius and he shared the Ethereal Shift ability with Solarius and countered Matt's Chaos Control-based speed attack with a technique called "Harmony Break".

After surrounding the entire way with warriors, both Warriors of Armageddon order the warriors to attack after stopping Gama's attack attempt. Infuriated, Gama prepares to unleash a deadly attack but is stopped by Matt who breaks through the first attack of the warriors with Dual Wield by wielding both Galaxia and Zeipo against Sol who bypasses only Galaxia after clashing with Zeipo and being countered with Matt cutting through Lunius and hitting him with a Dual Sword Beam making him vanish which infuriated Solarius. He attempted to attack Matt in rage, but Matt showed him his new ability "Starburst Stream" which defeated Solarius and destroyed the warriors, after that, due to exhaustion, Matt fainted.

Ruins of Civilization
After passing through the Painful Path, Matt and his brothers are welcome to the Scarlet Devil Mansion, as Matt wakes up in one of the rooms, he is welcomed by the chief maid, Sakuya Izayoi who says that she thought it was impossible for someone to defeat both Warriors of Armageddon, specially given to their situation: slim, apparently weak and with bad equipment, Matt tries to react but stops thanks to the body pain, as Sakuya states that she was kidding, she offers him some tea.

After Gama realizes that the inhabitants of the mansion are "weird"  he sets out to investigate, Matt then asks the owner of the Mansion, Remilia Scarlet for permission to visit the library, and once there, he is attacked by Patchouli Knowledge as she defends her library, she is stopped by Gama, Remilia says that she was never good at sharing as Matt asks what's in the basement of the mansion, Remilia replies it's her little sister, Matt asks if he can talk to her, Remilia says that she sees no problem but tells him to be careful.

Reaching the basement, Matt is forced to fight Remilia's sister, Flandre Scarlet, sefl-declarated "Dirty little secret of the Scarlet Devil Mansion", Flandre says she wants to play Danmaku and explains that Matt is the shooter, she attacks Matt, Hootch and Gama with Spell Cards of Taboo type, starting with Taboo: Scarlet Sense as Matt avoids the energy balls hiding under the bed, as she activates another Spell card, Taboo:Cranberry Trap surrounding Matt with purple orbs which he destroys with Sword Beam, amusing herself, Flandre activates Taboo:4-of-a-kind creating 3 clones of herself as she blasts the 3 continuously, Matt defends and dodges as much as he can before destroying one clone, before impact against the real one, Flandre activates Taboo:Deadly Scythe countering Galaxia with a sharp rod as they ascended through the mansion, Flandre screams to stop as she says it's sunny outside and gives up on fighting, as she says she had enough fun with Matt.

After the fight, the Warrior of Armageddon, Apolo appears and threatening them he destroys the floor of the Mansion before escaping from a barrage of arrows and Chaos Spear coming from Takeda and Harm who appear in the floating island in order to help, Remilia, infuriated activates Scarlet Devil: Scarlet Shoot sending Apolo outside of the Mansion, who turns to engage Gama in combat. As Gama humiliates Apolo and kills him, Matt seems to be surprised by his crushing power. Remilia gives them the Island map and a Special Spell card with something they might need and says farewell as they fly away.

Rebel City
Reaching the city of Yggdrasil, Matt and the others land and are susprised by a young boy holding a blade against them, as he asks if they are spies from Itachi, to which Matt replies they are not, he assumes they are the ones that defeated Solarius and Lunius, he introduces himself as Alec Cruz and reveals that he is the chosen by the Eternal Blade, Aqolo and that he is 12. Matt, introduces himself and his friends as Alec invites them to stay the night given to the dangerous situation of the Island at night, to which they accept.

As Alec offers Matt spare pyjamas, stating that they are almost the same height, Takeda calls him "shorty", Matt uses the Spell card from earlier, and blushing, he activates Strange Art: Liberation giving them 5 towels and 5 tooth brushes. As Alec offers Matt for him to sleep in his room, Matt accepts it and once ready to sleep they start talking about experience as Matt states he has none, Alec then offers to train with him.

During the training, Alec notices the different way Matt uses his blade and laughs at it, Matt runs and slams Galaxia against Aqolo, though, Alec didn't move with the attack as he asks if Matt is using the Super form before explaining Matt the Crystalian Evolution System, Matt asks him to show his Super form level 3 as Matt tries to keep up with his power, he kicks Alec and dodges incredibly fast attacks.

Itachi's clone shows up and attacks Matt, however Alec defends him and screams for him not to be scared as it was just a clone, Matt gains confidence and awakens his Sharingan to which Gama states that he got surprised himself. Matt advances against the clone and hits him with a kick, supporting on Aqolo and jumping before Alec throws Aqolo to him as he releases Water Force: Sword Beam destroying the clone, Gama states that for the first time he can say he is proud of him being his brother as Alec laughs at it, Matt replies that he is almost part of the family as his little brother, to which he replies he will accept his burden before asking him where he learned the attack as Matt replied it just felt natural.

A Crushed Future
After an intensive training, Alec tells Matt that he got strong enough so he could tell him about the God Blades, after explanation, Matt states that he wants to try fusing the blades, asking for Zeipo to Hootch. After trying to fuse them without sucess, Hootch states that they should try again after lunch.

After lunch, as the others rest, Matt and Hootch try again, this time with sharingan activated, both run and each other activating Chaos Control simultaneously resulting in a flash of light which teleported them to a Future where they where Chaos was vicotious. Matt, with Void Breaker in hands senses an enormous power which turns out to be Louis in the future, as he wields the Chaos Blade, Izanagi.

Both Matt and Hootch are rescued by Ciel who takes them to the Rebels Lair inside a ruined Crystalia where she scolds them on their disappearance for 30 cycles. As Matt witnessed the results of their disappearance on Derick, Takeda and Alec as they state that Harm have been killed by Louis himself during the incident of Heavenly City of Pain. Listening to them, Matt blames it on the God of Discord, Chaos, and also sets out to fight against him, but is fastly taken back by Ciel and binded by Alec with a low level Kido.

Ciel tells them about the Time Dial, an ancient artifact that is known for its power of time travel and its location inside Heavenly City of Pain. Matt and Hootch move to Heavenly City of Pain with Ciel and engage Louis in combat. As he overpowers them, Matt awakes his Dark Form and sends him flying against the wall which crumbles and makes him go through it, allowing them to touch the Dial with Takeda and Alec's help telling them to change the future as they go back to their time.

Getting to their time, Matt instantly walks around thanking his friends for being well, as well as Derick to which he says that he is glad that he is fine and is proud of being his brother. Matt then leaves the next day with his friends and Alec as they start moving away from the city of Yggdrasil.

An Inner Test
After flying through the Heavenly City of Pain, Matt and the others land near a forest to rest, as Takeda says that they were probably being tested, as a shadow appears and creates clones of each of them (except for Alec who was away from the floor).

As they try to defeat them, they seem to copy their every movement, Takeda then realizes a way of beating them as he sits on the floor and defeats his inner darkness in no time. Doing the same as him, Matt enters his inner world as he meets his dark self.

The Dark Matt mocks Matt's inteligence and height as well as his power, Matt initially didn't care and only fought against him, not realizing what he had to do. After he regained confidence on his power and on himself, he released a powerful Sword Beam against the Dark Matt, defeating him.

A New Future
Walking through the forest Matt and the others meet Itachi, as Matt attacks him, the spirit of Apolo uses Harmony Break against Gama's Chaos Control which ends up dragging Matt, Hootch and Gama into a bright light separating them.

Matt wakes up in Crystalia being poked by a young boy with a stick, as he woke up, the boy introduced himself as Tate. As Hootch asks Matt if it's some kind of good future, Tate says that it should be a good idea to take them to his dad, as he asked their names while flying, he stated that they were going to get along with his dad and uncle.

During the flight, Hootch asks Tate father's name, to which he replies it's Matthews Crystalus-Uchiha, surprising Matt who states that he himself is Matthews Crystalus-Uchiha, this time, surprising Tate, as Hootch replies that he might cause a Paradox by doing this, to which Tate replies it's fine since he didn't vanish. Upon reaching Tate's house, he is welcomed by his brother, Kain, who instantly asks him who are the boys with him, to which Tate replies that they are friends and also introduces his brother to both Matt and Hootch.

They are interrupted by a voice coming from inside the house calling both Tate and Kain to have lunch, to which Tate replies that it's his dad, before a Future Matt comes out, surprising Matt with his height. The Future Matt asks who are both, Tate also replies that they are new friends, Matt is again surprised by a Future Amy coming out of the house, asking if they were staying for lunch, after screaming in disbelief, Tate shuts Matt up.

As Matt stands shocked, the Future Matt asks where he has seem him before, to which Matt replies it's the first time they see each other. After thinking, Future Matt confuses him for a fanboy from Tate's school who compliments them on his look and the well made copy of Galaxia before touching it, to which Hootch replies he was the one who made it. After this he asks Amy to get his wallet and looks to a picture before laughing and saying that he never thought Hootch was the type of boy that lied, to which Hootch replies he is smarter than what he gives him credit for.

After stating that it's 30 years in the future, Matt gets scared by a Future Derick that appears out of no where. After a series of questions about Gama, Matt states they must find their Gama and their Itachi, to which the Future Matt says they are fighting in Heavenly City of Pain and states that things changed before inviting them to have lunch.

After having lunch, Matt and the others fly up to Heavenly City of Pain and meet Derick fighting Raina, as Future Matt interferes on the fight and stops both, a Future Louis is seen chaining a defeated Louis. After reuniting everyone, Matt asks his future self where their Hootch is, to which the Future Matt replies that he is busy.

Matt asks if he can know about his future to which Future Matt replies that he cannot tell him the future, since it is for him to live it, not know it. Matt replies to his answer saying that he is going to be a boring adult, to which Future Matt. putting his hand over his head says that once he gets older, he'll understand. They are interrupted by Louis who states that Apolo is still out there and that they must find him.

Returning to the house, Matt explains the situation as Future Matt, Future Louis and Kain state that the Harmony Break portion is keeping them there, remarking that if they defeat Apolo, they will be able to go back to their time.

Matt tells them to walk with Kain and Tate and also tells Matt to use a fake name, calling him Luke saying that this was going to be his earthling name as Matt accepts it. Matt walks with Kain as he explains the situation to his girlfriend, stating that he was their cousin Luke, Tate challenges Matt to a tag game which causes Matt to crash against the Overseer Tower's window sliding on the table as Future Matt talked with a man, which Matt recognizes as Hootch somehow.

After finding Apolo, Matt, his brothers and their future counterparts engage him in battle as Apolo changes his forms obtaining enormous power, Matt with the help of the Future Matt trespasses Apolo with an unknown ability which allowed them to move back to their time, however, with no memory of the adventure in the future. Once back, they keep on their journey to save Amy and defeat Louis.

Moonless Sky
As they advance to the Main castle, Louis casts an illusion through the Full Moon which traps Matt and his friends inside nightmares. As images from the broken future haunted him with Amy's death and others, Matt falls on his knees holding his head, however, memories of the good future also appear which encourage him into breaking through the illusion, before sending a sword beam against the sky, breaking the Tsukuyomi.

Lightning vs Light! A Battle of Speed!!
As Matt advances through the Main castle leaving friends behind to deal with other Warriors of Armageddon, Matt ends up meeting Itachi who engages him in combat, initially overwhelming him with his power, he tries to force Matt into releasing his dark power, as Matt resists his taunts, Itachi releases his powerful Sword Beam against Matt who is saved by Gama through Backslash surprising Itachi.

Itachi explains his reasons not to be using Tsukuyomi before attacking again with Amaterasu, aiming for Hootch and Gama. As they dodge, Itachi attacks them with Katon: Goukamekkakyu which is countered by Alec's Torrent, as well as Takeda who finds Itachi's hiding spot allowing Gama to attack Louis. As both fight, Matt discusses with Alec for a brief moment before Harm also appears stating that they are noisy. An enraged Itachi then uses Dark Galaxia to activate Silent Night and hide inside the darkness.

As no one can sense his power or even hear or see him, as he aims to kill Matt with a single slash, Matt surprises him by defending and pushing him back stating that he is right, that he surely doesn't have enough power to kill him, but has more than enough power to defeat him, saying that since he is a human, he should know that humans are the most selfish race in the universe, saying that he will simply beat him because he wants to, before knocking him out.

As Alec asks if he won, Matt states that it's not over before he points to the Main room's door where the real Itachi appears, defending a deadly blow from Gama, he moves fastly enough to touch Hootch's shoulder without him knowing it. Matt then activates his sharingan as Louis says that the real fun was just beggining.

Family Matters
Right at the beggining of the fight, Louis gives Matt a small cut to the cheek as he waves his sword, Matt screams to Takeda, Harm and Alec to find a way out stating that it's their business, as Louis mocks Galaxia for lending him power, he instantly demands Matt to show him the Dual Wield fighting style. As Matt gets Zeipo, Louis tells him to get inside the room as both positionate themselves, Matt thinks that the only way to end the fight was through Starburst Stream.

He starts attacking with a powerful barrage of attacks, occasionaly using the Double Sword Beam ability, which Louis slashes away. After evading a direct attack, Matt attacks Louis countinuously making him lose balance before attempting a Starburst Stream against him, which to Matt's surprised is countered, resulting on Zeipo breaking and Galaxia cracking.

As Louis continues his attacks, he kicks Matt to the wall before using a Sword Beam, sending him to floor after escaping, as he fastly moves in front of Matt breaking Galaxia leaving Matt defenseless. As Louis reveals Matt stating that she'd be the last thing he'd see in this world, he cuts Matt down as he reverts to normal form and falling on the floor, apparently, dead.

As Matt seems to be in nowhere and actually, dead, Matt hears a voice stating that he was just recovering, before he recognizes the voice as that of Buster Crystalus who states that he must go back and free Louis from the influence of Discord also telling him that he is strong, he asks him to give him and his mother, pride, as Matt awakens and activates his Sharingan which surprises Louis who believed he was dead.

Matt states that he is not the Louis he was supposed to know and says that he will bring him back even if he has to bring him down as he ascended to Super Form once again, without Galaxia's power. As he swears on his soul that he is not going to lose to Louis twice, he grabs both Galaxia's and Zeipo's hilts before using Chaos Control and fusing them into the God Blade, Void Breaker.

As Louis says that he still has a lot to learn, he appears behind Matt, who kicks him away. Louis is soon attacked again, dodging the attacks but gets kicked back again as he states that the power, expression and speed that Matt currectly has is that of the Hyper Form, surprising both Gama and Hootch.

As Louis attacks Matt, Matt senses the source of Discord from Dark Galaxia. Louis continues with Amaterasu to which Matt dodges by running through the walls, Louis follows with Katon: Gouryuuka no jutsu sending Dragon head shaped fireballs at Matt, as he escapes by using Sword Beam which cuts through the wall and vanishes to the skies as Louis states that it got bigger and more powerful.

Matt lands a punch to Louis, sending him to the floor, as a burst of power forces him away, an enraged Louis looks at him saying that he will kill him, Matt as an answer attacks with Starburst Stream, which sends him to the wall.

There he starts to know the power of the Stone of Chaos which had a powerful level of Chaos Energy, as it overloaded the machines inside the base, a soldier came searching for the stone, however, he is knocked out by Ciel.

Later, they plan on knowing the origins of the strange stone, but soon, Matt suffers side effects of his hyper transformation, reflected in nose bleeding. Matt then is told to go home and rest for some time, cosidering it was already late, to which he reluctantly accepts.

On the next morning, Matt is woken up by Gama who tells him that they have a mission and that Hootch had already gone earlier. After his everyday morning routine, Gama takes Matt to the base so he could know what was wrong with him.

As the doctor explained it was nothing to worry about, he told Matt to leave, shortly after, Gama goes in and talks to the doctor, returning fast to Matt, distracting him for enough time to apply a shot to hold his power inside. Matt and Derick then leave to their mission where they meet a faceless man in a suit, considered paranormal by Gama. After Matt enters his Dark form for a short period of time, they imprison the weird creature and go home.

Matt has a conversation with Gama about the souls of the Eternal Blades, surprising Gama with the topic of the conversation, as he asks Gama if he has any conversation with his sword, Matt himself explains that Galaxia's spirit is that of a little girl about his age with blond hair. After that, Hootch comes from the front door, hurt and falls on floor saying that Ciel had been captured.

Another strange soldier proceeds on showing Matt Aqolo and saying that he should kill him and mocks Matt for not being a Reploid before saying that thanks to him and his friends efforts, all the Eternal Blades forged by Galamon were there, before being knocked out by the real Gama who gives Galaxia back to Matt and takes an ID card from the fallen soldier.

This time, with the real Gama, they walk down the long corridor to a cell, where they find a girl named Soma, as they talk, she explains that she saw Ciel earlier, they are stopped by Aeon, but Gama stays behind to fight him as Matt runs with her, she asks him if he is confident on his abilities to which after reluctance, he says he is not.

He is then surprised by Hootch who shows up right in front of them, they keep on searching Ciel, and once they find her, she draws Ranshaw cutting a shadowy figure. Matt then realizes that Alec must be somewhere near since the swords were there. Hootch then realizes that they should fight Cain since they made it that far, Matt, consumed by fear of not being able to fight says that they should only find the others and leave.

Matt then finds Alec in a cell and Gama cuts down his chains of Black Crystals as Matt piggyback rides him, as Gama asks about the other wielders, Takeda comes down the hallway with Harm explaining that there are no others since only the blades being there there was no need for wielders.

After a long discussion, Matt decides to go with Alec, Harm and Takeda to  the throne room and face Cain. Hootch goes back on his idea and admits it's a good idea to leave, Matt, however kept on going, suppressing his own bleeding with pure will power.

After meeting Cain, Matt witnesses as he absorbs Alec, which triggers his Dark Transformation, however, after a short time, Matt falls down powerless and is also absorbed by Cain. Inside Cain's existance, he plots to escape using the protection of the Eternal Blades, and once out of his body, Matt cuts Cain with Zantetsuken which he copied from Gama, breaking his Shell of Immortality and fusing both Galaxia and Aqolo to create the God Blade, Deep Wave.

Matt however, lacking the power to control the blade, after sometime, falls down. Hootch and Derick who had left, came back to help, Hootch then proceeds on making Cain doubt his own goal with several questions as he asked what would happen if a god died, with Cain declaring that he'd find out, he vanishes and give up on his existance leaving behind Hootch's Harmony Crystal and the last Eternal Blades forged by Galamon, Ranshaw and Wind Driger. After explaining what the Harmony Crystal was, Matt goes home with his brothers for a well deserved rest.
