Infinite (Sonic the Hedgehog)

Infinite (インフィニット, Infinitto?) is a fictional character appearing in the Sonic the Hedgehog series. He debuted as the secondary antagonist in Sonic Forces. He is an anthropomorphic jackal, and the former captain of the Jackal Squad mercenary group. During a raid, Infinite was hired by Dr. Eggman to become the leader of the Eggman Army, only for him and his squad to fall at the hands of Shadow the Hedgehog while protecting one of Eggman's facilities. Ashamed of his loss, Infinite decided to obtain the power of the Phantom Ruby not only as a means of becoming stronger, but also to abandon his "weak" past self.

With his newfound power, Infinite aided Eggman by helping him expand the Eggman Empire to its largest size to date after defeating Sonic the Hedgehog. Near the end of the war with the Resistance though, Infinite would engage Sonic and the Avatar on multiple occasions until he was defeated during the decisive battle for the planet.

Joint ideas

 * Infinite makes silent appearances in DC vs. Sega. He appears in Sinestro's ending, on which he becomes Sinestro's newest recruit in the Yellow Lantern Corps, with Sinestro expecting Infinite to become a true embodiment of fear itself. He also appears in Terra's ending, on which he was assigned by Deathstroke to help capture Terra and get her to work for him. But both Deathstroke and Infinite end up ultimately defeated when Terra (using her Earth-manipulating powers) manages to gain control of the Phantom Ruby, which she uses against Infinite, and later empowers her Earth constructs.
