- Not to be confused with Cyborg Sonic (Sonic Boom).
Cyborg Sonic is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is an alternate version of Mobius Prime's Sonic the Hedgehog from another dimension.
Cyborg Sonic has blue fur and black eyes, and his right half of body is robotic due to partial Roboticization. He wears black jacket, a white glove on his natural hand, and and shoes similar to Sonic prime's.
On his Mobius, Dr. Robotnik attempted to defeat the Knothole Freedom Fighters by turning them into cyborgs. However, the partial roboticization only made them stronger. Cyborg Sonic led them into Robotropolis for a final confrontation with Robotnik. Robotnik turned the tables by completely roboticizing himself. With his teammates killed or otherwise neutralized by Robo-Robotnik, Cyborg Sonic fled onto the Cosmic Interstate looking for help to free his zone.
He arrived on Mobius Prime and explained to Sonic Prime his situation. Realizing the threat Robo-Robotnik posed to the Multiverse, he gathered an army of fellow alternate Sonics to combat the foe. Cyborg Sonic joined the final battle, helping to defeat the Giant Borg and fragment both the robot and Robo-Robotnik. He took his severed head as he departed back to his own zone after the battle.
- Cyborg Sonic's character and story are nods to the Terminator franchise.
- Cyborg Sonic along with Sonic's future version were once thought to be the same character, according to former writer Ken Penders. Writer Ian Flynn revealed they are separate characters.
