Once the great leader of a pack of mercenaries made of fellow Jackals ( presumably family ), Infinite is now Dr. Eggman's main line of defense for his robot armies.. Or at least, he was.

After a pride-crushing defeat at the hands of Sonic the Hedgehog & Amy Rose's Resistance army, Infinite's trump card, the mystical Phantom Ruby, is taking a toll on his body & mind. Nevertheless, he attempts to carry a sense of strength through the pain in hopes of getting revenge against Sonic & reuniting with his lost Jackal Squad.
