Infinite

Infinite (インフィニット), formerly known as the "ultimate mercenary" (究極傭兵), is an antagonist that appears in Sonic Forces. He is an anthropomorphic jackal, and was formerly the leader of the Jackal Squad mercenary group. During a raid, Infinite was hired by Dr. Eggman to protect his facility, only for him and his squad to fall at the hands of Shadow the Hedgehog. Ashamed of his loss, Infinite decided to obtain the power of the Phantom Ruby as a means of not only becoming stronger, but to also abandon his "weak", past self.

Concept and creation
During the original drafts, Infinite was originally called "Zero". His final name ("Infinite") was intended to reference the nature of his ability.

According to Shun Nakamura, Infinite was created with an impressive and strong presence in mind since he would be accompanied by old bosses in Sonic Forces. This is the reason why he was made stronger and faster than Sonic the Hedgehog. His nature likewise inspired the staff to elaborate on his origin story. Sonic Team was also peculiar about giving him a cool, but evil design, with his mask being designed especially to emphasize his evil nature.

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. 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 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, 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.

Infinite possesses the finalized 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.

Past
Infinite was once the leader of the Jackal Squad, who decided to invade one of Dr. Eggman's bases one day to steal his devices for a bounty. The doctor, who recently discovered the Phantom Ruby, used the newly-found 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 together could 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, which they were assigned to guard. 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 finalized Phantom Ruby prototype 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.

Sonic Forces
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.

Personality
Infinite is an enigmatic and mysterious, yet lethal and dark figure. He is 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 lets 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 reveal a desolate, war-torn world. It also seems that he greatly dislikes stagnation, admitting as he joined Eggman that he had grown tired and bored of the world, and desired to change it, evidently for the worst, just to provide some amusement.

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 his "pathetic face" to him ever again, Infinite proceeded to rage about how he was not weak before ultimately subjecting himself to being fused with the Phantom Ruby prototype, 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 was not weak, almost like a paranoid reassurance, showing Infinite as a truly insecure individual.

Powers and abilities
Described as powerful, Infinite is said to possess a strange ability. His power surpasses even that of Sonic's, whom he was able to defeat in combat with relative ease. He was also able to effortlessly defeat E-123 Omega in a flash. Likewise, Infinite was also capable of defeating Silver the Hedgehog with ease.

Due to Infinite's fusion with the finalized version of the Phantom Ruby prototypes, he acquired the ability to generate, destroy and/or manipulate virtual realities. The virtual realities in question are said to be illusions, and these illusions are generated by distorting the sensory spatial depth and information perceived by a living target of intention. The effects of the virtual realities created by the Phantom Ruby are said to be potent enough to cause any illusory injury due to their influence, to affect the victim's physical body. In battle, Infinite primarily uses the Phantom Ruby to generate a huge supply of crimson red cubes that he can skillfully and willingly move around. He can generate and arrange a large numbers of these cubes into a variety of different forms. He can also use them to manifest other objects, such as turrets for example.

Infinite can also use the ruby's power to create virtual reality constructs that cause victims to falsely perceive the presence of other characters, such as Zavok and Chaos. These constructs are described by Shadow as having "mass and form, but no heart or soul". These constructs, so long as Infinite desires, can also carry the memories, powers, and personalities of the originals. He can also alter them to make them stronger than the originals such as making Metal Sonic bigger and granting him the ability to use electrified versions of his energy cubes as well as materialize objects to use as a shield. Infinite can also use the Ruby's power to alter his own appearance such as making himself bigger for his final battle with Sonic. Using the Phantom Ruby's power, Infinite is also capable of creating Null Spaces, which are seemingly inescapable voids in space-time that function similar to that of a black hole. Some of Infinite's other Phantom Ruby-based skills include the ability to fire energy blasts from his hands, the ability to teleport in a manner that makes it seems as if his body is being deconstructed into cuboid objects, and the ability to levitate through the atmosphere and through space.

After gaining the Phantom Ruby's power, Infinite obtained unprecedented speed and acceleration that surpasses even that of Sonic himself, able to easily dodge one of Sonic's attacks even when he was boosting at point-blank range and move several meters almost instantaneously. He possesses far greater strength than Sonic as well, enough to knock away someone of Sonic's size with enough force to crack a concrete arch upon impact. Prior to being fused with the Phantom Ruby, he was skilled at swordplay, and was shown to be fairly fast and agile in his movements, although his speed was easily outclassed by Shadow's Chaos Control abilities.

Weapons
Prior to receiving the Phantom Ruby's power, Infinite possessed a red sword, which he used with great proficiency, using it to slice through robots with ease.

Shadow the Hedgehog
Arguably the person who had the most impact on Infinite was Shadow the Hedgehog. After his squad was destroyed by the brooding hedgehog during an attack on Eggman's base, Infinite, furious, attempted to attack him, only to be effortlessly defeated. Before he left, Shadow made clear his disgust, and demanded never to see his "pathetic face" again. Infuriated that he'd been humiliated, the mercenary took Shadow's words to heart, and went on to discard all remnants of his old life, becoming the entity known as Infinite.

Much later, Infinite once again encountered Shadow, having defeated Omega, and was ecstatic, though Shadow failed to remember him. Infinite's reaction to this was to cast Shadow into a false interpretation of Green Hill, where Shadow would be falsely contacted by an Omega who at first, seemed to be perfectly normal, but as time progressed, soon devolved into incessantly repeating that he was not weak. Infinite later uses a false Shadow to help instill fear into the Resistance during Eggman's reign.

It's implied that Infinite was afraid of Shadow before he took his current identity, visibly trembling as the hedgehog criticized him.

Sonic the Hedgehog
His first meeting with Sonic the Hedgehog had him beating the blue hedgehog effortlessly. This ultimately had Infinite's ego receiving a massive boost. When meeting Sonic for the first time since he defeated him at Mystic Jungle, Infinite proceeded to sense a smell from Sonic and assumed the smell was fear of encountering him due to last time, though Sonic corrected him and explained the smell was actually sweat due to Sonic having ran all the way there, and also smugly explained that Infinite had not left an impression on him at all. Because of his beating Sonic twice, he proceeded to spare him, solely because he deemed him not worth killing. This would ultimately prove to be his downfall, as not only did Sonic proceed to inspire the Avatar to fight off against him, but both Sonic and the Avatar proceeded to bring him down for the count even with a fully charged Phantom Ruby.

Avatar
Infinite had a personal connection with Avatar, as he had been responsible for slaughtering their friends during one of his raids, with Infinite ultimately sparing them simply to satiate his more sadistic nature of watching them flee in terror. They later re-encountered each other at Metropolis, with Infinite trying to intimidate Avatar, although they, due to Sonic's word of encouragement, ultimately chose to fight Infinite instead of giving in to fear. Infinite then tried to finish them off when remembering who they were, although due to Avatar's possession of a Phantom Ruby prototype, they managed to evade the attack, leaving Infinite shocked before ultimately dismissing the matter and leaving them be. Ultimately, the Avatar alongside Sonic ended up bringing him down for the count.

Dr. Eggman
When Infinite and his squad raided Dr. Eggman's base for weapons to sell, the doctor's army overwhelmed them, and the Phantom Ruby allowed Eggman to get the upper hand against Infinite. Impressed by the jackal, Eggman offered him a place in the Eggman Empire. Infinite, having grown bored with his life, agreed to his proposition. Infinite was later a willing subject in the Phantom Ruby experiments, and had the final version merged with his very being.

Following Eggman's domination of the Earth, Infinite would continue to prove loyal to the doctor, serving as his right-hand and enforcer, though he did not hesitate to voice his displeasure with some of Eggman's choices, and openly acknowledged himself as the better of the two. Interestingly, Infinite is one of the only powerful entities that Eggman aligned himself with who did not end up betraying him.

Jackal Squad
It would seem that Infinite was close to his former squadmates in the Jackal Squad, as he was furious when Shadow destroyed them. Likewise, the rest of the squad seemed to place a lot of faith and trust in Infinite, believing that they could survive on their own, though ultimately, Infinite's desire to end his boredom proved more important to him than the interests of his teammates.
