Cinos the Anti-Sonic is a character that appears in Sonic the Hedgehog in the Fourth Dimension. He was an alternate version of Sonic that was turned into his opposite by the use of the ROCC at the same time Kintobor became Robotnik.
Cinos had white fur. His expressions appeared to be those of complete evil, as shown when he and Sonic merged.
When Sonic and Tails went back in time to undo their undoing of Kintobor's transformation, the version of Sonic from that point in time was caught in the ROCC's blast, turning him into an evil being filled with Chaos Energy. Cinos proved to be a match for Sonic and the two Tailses, whirling at high speeds, until his sneaker caught on the floor, leaving him prone. Tails then found three gold rings to use on Cinos, believing they could "neutralize his energy" as Sonic put it. It did not work so well, so Sonic touched Cinos instead and slowly absorbed him, as he was his temporal duplicate.
Powers and abilities
Cinos was every bit as speedy as the real Sonic. His body was also apparently filled with Chaos Energy.
Cinos' Chaos Energy-infused body proved to be his downfall, as rings can be used to neutralize his energy.
