Mephilie's Jackal friend and Boss

He calls Mephilie "JJ" since he also knew her by her jackal name "Jackie"

"That day, I gave up my own unsightly face. And I let go of the old me, the one that was so weak, so that I could become stronger. And then, at last... I obtained the power. The power to make all yield to my will. I... was... REBORN!"

Name: Infinite

Species: Mobian (Jackal)

Gender: Male

Appearance: Infinite is an anthropomorphic jackal with black fur. He has white long and stiff quills. He 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-lined 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 muzzle with cheek tuffs and a black nose.

After abandoning his old identity, Infinite began wearing a silver-colored mask with large ears with white and black circular patterns on the inside. While his left eye (which is colored yellow) is visible as he wears the mask, his right eye is covered by a black lightning bolt-shaped piece, similar to an eyepatch that covers his scarred eye.

Infinite possesses the Phantom Ruby that is fused with his chest, which, when Infinite channels the power of the gemstone, can surround him in a red aura, with red, glitch-like pixel particles scattered throughout his body.

Powers:

Flight - Infinite has shown the ability to fly and hover similar to those within a Super State, like Super Sonic for example.

Speed - Infinite has been shown to move quite fast, enough so that he could side step a boosting Sonic at point blank and even attack him. He was also shown to move towards The Avatar Character at high speeds in a flash of red, close to teleportation through the Phantom Ruby's power..

Cubes - Infinite's first shown ability was the creation of cubes. Given his name, it's quite possible he could make infinite amounts. These cubes can harm enemies, and if Infinite wishes subject them to his will. Tails describes being hit by a cube as "being placed within a dream where reality changes. Taking damage within this dream equals taking damage in the real world."

For example, the Avatar Character when hit by the cubes, is forced to dodge cannons that had not been there before hand. Getting hit by a cannon brings one back to reality while damage carries over. Another example is when Sonic fights Infinite and, if touched by the cubes, large spiked balls begin to fly towards Sonic. In the last battle, multiple lasers begin to fire at Sonic and allies once touched by a cube. Shadow was subject to this ability, put in a virtual world of Infinite's making. Everything seemed perfect until later in the simulation where the fake Omega began to repeat itself rapidly.

Infinite can also use the cubes to manifest creations such as turrets.

Bullets - Aside from cubes, Infinite has shown the ability to fire bullets of energy from his hands.

Laser Beams- Infinite was capable of producing highly destructive beams of energy from his hands.

Shock wave- Infinite has also shown the ability to charge up a powerful shock wave. It shows the same effect from when one touches the cubes, and then more effects, such as gravity manipulation, the creation of large monstrosities baring Infinite's appearance loosely to fight in Metropolis. The greatest known alteration was when Infinite brought down the Sun to Mobius, ready to drop it on the world despite how that would effect the entire planet.

It's easy to say that, when this shock wave occurs, it's Infinite using the Phantom Ruby to alter reality to his pleasing.

Strength- Infinite has been shown to be quite strong, kicking Sonic the Hedgehog hard enough to break the wall he'd slammed into, cratering the walls twice.

Agility: Infinite showed great agility, even before gaining the Phantom Ruby.

Cloning: Infinite can make infinite copies of those he's met or know of, such as Metal Sonic, Shadow the Hedgehog, Chaos, and Zavok. He made an entire army out of these major villains and in Shadow's case Anti-Hero. They are as strong as the original, but lack the heart and soul. Perfect pawns. Infinite can even make them stronger, adding special affects to their abilities.

Teleportation:  Infinite can teleport in a manner that makes it seems as if his body is being deconstructed into cuboid objects.

Form Alteration: Infinite can also use the Ruby's power to alter his own appearance such as making himself bigger for his final battle with Sonic.

Sword Skill: Infinite is a practice swordsman, it being his primary way of combat before becoming known as Infinite.

Leadership Skills: Infinite was the leader of Jackal Squad, which was a mercenary group that would take various jobs until they were defeated by Shadow the Hedgehog. Their fates are unknown.

Voice Alteration- Infinite's mask alters his voice and the appearance of his left eye, giving it red sclera instead of normal white sclera that hides behind the mask.

Null-Space: Infinite's deadliest attack, he throws forth an orb of Null-Energy created by the Phantom Ruby and can attack it, creating a black hole into an alternate world with almost no escape. It took the extreme speed of Sonic and the Avatar Character's Double-Boost to make it out, barely at that.

Personality: Infinite is an enigmatic and mysterious, yet lethal and dark figure, cold and stern, though deeply sadistic and cruel. Prior to becoming Infinite, however, he had at least some degree of care for his men in Jackal Squad, as he angrily confronted Shadow over the destruction of the Jackal Squad before fighting him. He is also extremely sadistic, taking great pleasure in the pain and torment of others. He even willingly let's the Avatar run unharmed, just so he could relish in their terrified screams. Extremely collected and confident with a cynical, nonchalant demeanor, he presents himself as perceptive and aloof, toying with and barely sparing his enemies a thought even in direct combat. He also appears rather arrogant and sure about his strength, as he often exhibits a sense of superiority when talking to others and shows little respect for figures like Sonic. He is, however, able to acknowledge attributes to his opponents he deemed commendable, as he acknowledged before attacking Omega that the latter was "spirited." His violent disposition was present even before his transformation into Infinite, as evidenced by his touching the Phantom Ruby causing it to show a world that was desolate.

His most notable character trait, however, was his inferiority complex, especially regarding any perceived weakness he might have. This was most especially apparent when he fought Shadow and was easily beaten by him. After Shadow bluntly told him he was worthless and told him to not show "[Infinite's] pathetic face" to him ever again, Infinite proceeded to rage on how he was not weak before ultimately subjecting himself to being fused with the Phantom Ruby, and completely discarding any trace of his old identity, to the point where he refused to show his own face. Other indications of this trait were shown where he expressed disgust at Eggman calling a retreat, viewing it as a tacit admission to weakness. Even after his defeat, Infinite tries to insist that he can fight on, even as he is pulled from the battlefield. This inferiority complex is implied to have developed into a mad obsession with strength. When Shadow runs through a Phantom Ruby-made Green Hill, Infinite's thoughts are echoed through a false Omega, constantly repeating that he wasn't weak, like a broken record, almost like a paranoid reassurance, showing Infinite as a truly insecure individual.

Bio: Infinite was once the leader of the Jackal Squad, whom decided to invade Eggman's Facility one day to steal his devices for a bounty. Dr. Eggman, who recently discovered the Phantom Ruby, used the newly-founded gemstone to conjure an army of Egg Pawns, giving the Jackal Squad some opposition. Infinite commanded his forces to handle the robots as he targeted Eggman straight ahead. Infinite's sword, however, struck against the Phantom Ruby, giving a vision of what Infinite desired the most: a desolate, destroyed world. Eggman, who also saw Infinite's vision, realized that he and the jackal leader that together, they can accomplish their goals. Offering Infinite a chance at joining his side as the Jackal Squad was cornered, Infinite accepted the proposal.

Later on, Infinite and his squad eventually fell victim to Shadow the Hedgehog, who infiltrated Eggman's Facility. After being berated by Eggman for his incompetence at protecting the facility, Infinite ambushed Shadow, only to be completely subdued by the brooding hedgehog. Calling the jackal leader worthless, Infinite broke into a tantrum, realizing just how weak and humiliating he truly was.

Infinite would then seek out the alligence of the Eggman Empire, fusing with the Phantom Ruby in an attempt to become stronger and seek out vengeance against Shadow. With his newfound power, Infinite abandoned the former, weak version of himself, gaining a mask to hide his scars, symbolizing his rebirth.

Shortly after obtaining his powers, Infinite was dispatched by Dr. Eggman to deal with E-123 Omega, who had proceeded to slaughter a whole lot of Eggman's henchmen on his way through Eggman's base. Confronting Omega, Infinite proceeded to effortlessly defeat the robot with his abilities.

In Sonic Forces, Infinite became the right-hand man of Dr. Eggman. When Eggman attacked a large urban center with his robots, Infinite engaged Sonic the Hedgehog when the latter made short work of Eggman's forces. Overwhelming Sonic with his power, Infinite defeated and captured Sonic.

After's Sonic's defeat, Infinite provided Eggman with a new power that allowed the doctor to conquer 99% of the planet, resulting in the Eggman Empire controlling that much of the world. Instated as the leader of Eggman's entire army, Infinite worked alongside Eggman's henchmen (Shadow the Hedgehog, Metal Sonic, Zavok and Chaos) and it is his existence that binds the aforementioned individuals in Eggman's army. However, Infinite eventually found opposition in the form of the Resistance.
