Louis Crystalus-Uchiha

Louis Crystalus-Uchiha is the first son of Buster Crystalus and Sapphire Uchiha as well as the primary antagonist of Crystal Chronicles. He is also the ex-chosen of the Eternal Blade, Dark Galaxia.

Background
Louis, as the first child of Buster and Sapphire, was given special training and soon was recognized as a prodigy among the crystalians and the Megabusters, once getting to the age of 16, he was invited to become a Warrior of Harmony, to which he accepted.

During his first mission as a Warrior of Harmony, he was abducted by the Warriors of Discord and brainwashed by Chaos' influence over his Eternal Blade, Dark Galaxia, which made his personality change compared to earlier. As he lived as a Warrior of Discord, upon reaching the age of 18, he started killing minor gods and Gods of Nature, adding their power to his, thus, creating the Heavenly City of Pain and receiving the title of "Godslayer".

He disguised himself as a man and visited Earth to find his lost brothers, finding and bringing Derick, naming himself "a friend", then again, he returned to Earth, attempting to drag Matt and Hootch back to Crystalia, however, his plans were foiled by Cosmos, who teleported them to safety, with that, he returned to Crystalia to wait for a chance to face his brothers together.

Personality
Louis, before Discord, was a calm person that fought when necessary, despite being the chosen by Dark Galaxia, he had never shown any link with darkness or its powers. As a Warrior of Discord, his personality was changed significantly as he recognized his own power and used it as he wanted, becoming a sarcastic and arrogant man.

During his fight with Matt he was shown to be slightly sadistic as he attempted to cut Matt while he was down and trapping him inside his nightmares, apparently enjoying it while it happens. He started enjoying threats as well as he threats Derick by telling Hootch and Matt the truth about their bloodline and their family, having fun with it.

He has the habit of underestimating his enemies, as showed by Matt's fight where he repeatedly called him "little" or "little brother" implying that he never believed he could be able to defeat him.

When Purified, Louis takes part of his former personality back, however, mantaining his arrogant personality and sarcasm, as well as mantaining the crystalian personality, which tends to be cold.
