When Bryan Gordons found out that he had two of the rare, recessive gene required to survive the transformation into a psi morph, he wasn't interested. He had been doing grunt work at construction sites for many years, was very good at what he did, and just wanted to continue doing his job.
Unfortunately for Bryan, a certain psi morph had decided that Bryan had a duty that he must perform, and took it upon himself to force Bryan into doing this duty. The psi morph used mind control to get the construction worker to travel to Dr. Varin's lab, and ask to be transformed. Dr. Varin did not realize what had happened until it was too late.
Now known as Brickhead (a code name he gave himself because he felt stupid,) he grudgingly joins his fellow psi morphs in battling the robot threat. He hates what has happened to him and he hates having to fight, but he doesn't think there is any other way for a talking, humanoid rhinoceros to earn a living. Dr. Varin has found Brickhead's form to be incompatible with a human reserve body.
His main weapon is a techpaw which transforms into a huge metal fist. He can deliver devastating punches with this weapon, and he can also punch the air to send a shockwave at his foes.
