Infinite

Intro Infinite (インフィニット, Infinitto?), also known as the "Ultimate Mercenary" (究極傭兵, Kyūkyoku Yōhei?), is an antagonist that appears in the Sonic the Hedgehog series. 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 engaged Sonic and the Avatar on multiple occasions until he was defeated during the decisive battle for the planet and consumed by the Phantom Ruby.[2]
