Xenin the Echidna

Xenin was a powerful Echidna warrior and member of the Dark Legion. Nearly his entire body had been replaced with cybernetic enhancement designed to make him a superior fighter to Knuckles the Echidna in every way. During the Dark Legion's attempt to take over the High Council of Echidnaopolis, Xenin captured General Von Stryker and imprisoned him as well as Knuckles and Julie-Su. He eventually met his demise imprisoned in an Egg Grape Chamber. He has brown fur and blue eyes and is covered in cybernetics. He wears cybernetic enhancements

Political Agenda of the Dark Legion
In 1999 (technically 3236) when the Dark Legion sought to take over Angel Island by controlling the High Council, Xenin was dispatched to "send out the party message" according to Dimitri. Instead, Xenin took this time to apprehend various people who might cause problems during their campaign. Travelling to the Dingo section of the city, Xenin emerged from the shadows before General Von Stryker while the nearby Dingoes were apprehended. Xenin quickly and easily defeated Von Stryker in a fist fight and ordered the Legion troops to apprehend him, while forcing the other dingoes into the under ground sewers to be locked up.

Not long after this, Xenin showed up before Knuckles and the Chaotix with a group of Dark Legion troops. Informing Julie-Su he had orders to bring her back to the Dark Legion, he shot a laser blast at her saying "Suppose I miss and accidentally kill you if you refuse!" in response to Julie-Su's sarcastic decline to go with them. Knuckles responded by attacking Xenin, though his punch did not even damage his body. Xenin then knocked Knuckles out with a single punch, and subsequently captured him and Julie-Su. (KtE: #23)

While Dimitri prepared Knuckles for examination to discover the key to his powers, Xenin toyed with the captured Von Stryker, beating him while he was bound and hung upside down. When Julie-Su sarcastically pointed out Xenin's humor was pathetic, he places his plaster to her forehead and threatened to "test it out" on her, asking if she'd like to volunteer. When the complex began to blow up due to Knuckles' powers interacting with the Dark Legion systems, Xenin left Von Stryker and Julie-Su for dead, stating "All I see are enemies and traitors deserving whatever happens to them!". After informing a Dark Legion troop Dimitri left orders not to be disturbed by anyone for any reason, he evacuated the complex. (KtE: #24)

Death
In 2004 (technically 3237), Xenin became a victim of the Egg Grape Chambers after being captured by the forces of the Eggman Empire. He eventually perished due to the effects of the chamber. (StH: #141)

Abilities
Due to his cybernetics, Xenin was a powerful warrior who could match even Knuckles's power and close combat capabilities. He was also trained in using fire arms such as laser pistols. Though seemingly lacking in intelligence, Xenin compensated for this with his brute strength and loyalty to the Dark Legion. (KtE: #24)

Personality
Xenin was arrogant, malicious and violent. He showed signs of outright racism towards the Dingoes, ordering Dark Legion troops to lock them in the underground sewers. With a short temper and little patience, Xenin threatened those who he felt offended him or disobeyed his orders. He also had no regard for the lives of those he deemed useless, which included just about everybody who was not a member of the Dark Legion. (KtE: #23, #24)
