Infinite

Infinite (インフィニット Infinitto?), formerly known as the "ultimate mercenary" (究極傭兵 Kyūkyoku Yōhei?), is the 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.

Appearance
Infinite is an anthropomorphic jackal with black fur. He has white long and stiff dreadlocks, a white collar of some kind, and white stripes on his back that resemble a ribcage. He also has a bushy tail with a white tip, and wears black gloves with silver streaks on the back, covering his sharp fingers. He also has pointed, metal black hi-tops, with his personal infinity symbol engraved on red soles. His right eye is colored blue, though he has a scar across it, and his left eye is yellow. He also has a medium-long white muzzle with cheek tuffs, a black nose, and noticeable fangs. After abandoning his old identity, Infinite began wearing a silver-colored mask with large ears with white and black circular patterns on the inside, with the right ear being black with white circular patterns and the left being white with black circular patterns. While his left eye is visible through a red visor, his right eye is covered by a black lightning bolt-shaped piece, similar to an eyepatch, that is connected to his mask's right ear, which glows red when he uses his power.

Infinite possesses the finalized version of the Phantom Ruby prototype that is fused to his chest. When Infinite channels the power of the gemstone, he can surround himself in a red aura, with red, glitch-like pixel particles scattered throughout his body.

Personality
Before fusing with the Phantom Ruby prototype, Infinite was a violent, heartless, and vicious gun-for-hire whose main interest as a mercenary was to earn bounties. Openly encouraging his subordinates to go for the kill, he had no qualms about taking a life. Beneath this facade, however, he harbored darker, almost nihilistic desires for anarchy: when he struck the Phantom Ruby, it caused it to reveal his deepest desires in the form of a desolate, war-torn world. Implied to greatly dislike stagnation and the current world, he admittedly joined the Eggman Empire because he had grown tired and bored of the world, and desired to change it, evidently for the worse, just to provide some amusement.
