Infinite | She's... still alive.

Infinite is an anthropomorphical jackal, and the former leader of the Jackal Squad mercenary group. Now, after her defeat at the hands of Shadow the Hedgehog, she now serves Dr. Eggman and is part of the Eggman Empire. She's one of the many Trump Cards of the Eggman Empire, especially due to her mastery of the Phantom Ruby.

Before fusing with the Phantom Ruby, Infinite was a selfish and arrogant mercenary whose Jackal Squad had a vicious reputation. Openly encouraging her subordinates to go for the kill, she had no qualms about taking lives to obtain bounties. She also had a large ego, using the title of the "ultimate mercenary". When Infinite first encountered the Phantom Ruby, it revealed her true desires in the form of a desolate, war-torn world. She then ignored his comrades and chose to join the Eggman Empire, as she had grown bored of the world and sought to change it, evidently for the worse, just to provide some personal amusement. While working for Doctor Eggman, she held little respect for him.

However, Infinite's ego was completely shattered when he was so easily beaten by Shadow the Hedgehog. Infinite hated that Shadow defeated her subordinates, but she completely detested her own terrified reaction to Shadow's power in this encounter, conflicting with her preconceived views of herself. This sent her into a spiral of fear and self-hatred, leading her to cast away her previous identity and wear a mask so she no longer had to see her own cowardly face as she became Eggman's right hand, agreeing to fuse herself with the Phantom Ruby.

Once her pride was crushed and she was faced with true fear, Infinite comforted her ego by using the Phantom Ruby to grow stronger so she could inflict fear in others instead. Infinite again arrogantly believed she was unbeatable, her pride returning a hundredfold. She shows great pleasure in destruction and sadistically torments her enemies as she crushes their forces, relishing in her own ability to make others fear her, the same fear and despair that she once felt. At her core, Infinite has a selfishly individualistic outlook on the world and a sadistic fascination with fear.

Infinite speaks in a theatrical and self-important manner, with others noting that she has a "big mouth". She also has a dark, dry sense of humor, often mocking her enemies with cruel jokes. Unlike Dr. Eggman, who excitedly reveals his plans while gloating to his enemies, Infinite never reveals anything about herself, remaining aloof and mysterious. She claims that it was natural for the strong to vanquish the weak, placing herself at the top of the hierarchy.

Though her confidence is not without validity, Infinite's hubris is so great that she sometimes leaves her enemies to grovel in fear rather than finish them off, believing fully that they are no threat to her; this may also be inspired by his encounter with Shadow, who did the same to her. Similarly, her confidence is such that he even rubs Eggman's failures. On some level, Infinite also desires a challenge, as she wonders if the world had any challenges left. She is, however, able to acknowledge attributes of her opponents she deems commendable.

Despite all her illusory power, Infinite is clearly still scarred by her encounter with true power. She remains highly insecure and loathes her "old self". Infinite also refuses to count on anyone but herself, forming illusory Phantom Copies as little more than drones in her army.

After Infinite's fusion with the finalized Phantom Ruby copy, she acquired the ability to generate, destroy, and manipulate virtual realities, which she can turn into virtual reality projections to interact with reality. Said virtual realities are illusions, which Infinite creates by exercising control of one's visual and depth perception by feeding the brain false information. She is able to use her projections to enable her virtual realities to interact with the real world in order to bestow powers on herself. Having no limitations to the illusions she can create, Infinite has, within the influence of her Phantom Ruby, unlimited abilities.

Infinite can also use her Ruby to give herself the power of flight and levitation, deadly energy beam emission, energy ball projection, self-replication, size enhancement, shockwave manipulation, gravity distortion, object materialization, and teleportation. Infinite can also use her Ruby's power to create Phantom Copies that cause her victims to falsely perceive the presence of other characters. These copies have mass and form, but no heart or soul. These copies, so long as Infinite desires, can also carry the memories, powers, and personalities of the originals.

While Infinite's illusions are formidable, they can be neutralized by someone who has a Phantom Ruby prototype. Likewise, her finalized Phantom Ruby copy's illusions only work if the target is within the Ruby's field of effect and are tangible. Also, hier finalized Phantom Ruby copy requires a tremendous amount of energy to function. Should its energy supply be cut off, her finalized Phantom Ruby copy would be rendered inert.

Another weakness of Infinite's is her extreme sense of confidence and constant need to satisfy her sadism.

Appearance wise, Infinite is an anthropomorphic jackal with black and white fur. She has a ribcage-like patch of some of her white fur around the upper half of her body, a bushy tail with a quintet of curved tufts at its tip where the tail bears its white coloration and long, white and stiff dreadlocks. Her muzzle is white and protruding with pointed cheek tufts and she has a black nose, noticeable fangs and a large and white scar across her right eye. Infinite has complete heterochromia, with her aforementioned right eye being blue and her left one being yellow. For attire, she wears a white neckerchief and black gloves with silver and "greater/less than" symbol-like designs on the backs, covering her sharp claws. Infinite also wears pointed and metal hi-tops which bear a black and silver coloration, triangular straps and her personal infinity symbol engraved on the red soles.

Infinite also wears a silver-colored and metal mask that has a pair of hollow oval-shaped patterns on the insides of the ears, with the right ear bearing a black canal with white patterns and the left ear bearing a canal with the opposite color scheme, and a somewhat polygonal underside. While Infinite's left eye is visible through a red and crack-styled visor, her right eye is covered by a black and lightning bolt-shaped piece akin to an eyepatch that is connected to her mask's right ear canal, which glows red when she uses her power.

FInally, Infinite is around six feet tall, extremely busty with thick thighs and a plump rear. She's fairly athletic and quite powerful physically even without her Phantom Ruby.
