Cyber is a mutant monitor lizard who belongs to a science fiction setting. He appears more animalistic than human, despite having the intelligence, and doesn't concern himself with human norms and conventions.

Cyber is a prototype experimental soldier made to follow orders and fight, but the company developing them went bankrupt before they could produce more. Cyber was left as their sole successful creation, but without the job he's supposed to do he's rather lost. He gets by working as a security guard or manual worker for whoever gives him something to eat and somewhere to sleep.

Though he seems a mindless monster, Cyber is pretty clever and has no trouble understanding things or figuring out a way around a problem. He's not very introspective and doesn't think when it's not necessary but rather lies around saving his energy. He's an excellent fighter programmed with quick reflexes, a high pain threshold and incredible endurance. He performs best in open or rugged terrain, forests or places with lots of obstacles slow him down as he's not very swift and flexible.

Cyber was engineered with venom glands that run through his body and add various poisons to his saliva and claw tips. He can alter the toxins by inserting different plugs into his back or arms, changing the effects of his venom according to his current assignment. He has little need for them in his current jobs, but keeps a few vials around just in case.

Keeps to himself, rarely talks, takes things as they come. Likes warm places such as boiler rooms and loves basking in sunlight.
