Code Name: Red Rage
Also Known As: The Rage, Big Red
Real Name: Professor Thomas Trainer
Powers: Super human strength, speed and agility, high level of resistance to pain and injury.
History: Thomas Trainer was a nuclear physicist experimenting with a new type of "exotic" energy generation. Little did he know, but the equipment had been donated by the Benefactor and was intended to harness the energy as a power source for one of his experiments. however the conflicting instructions caused the equipment's safety protocols to fail leading to a near lethal release of exotic energy particles.
At first Trainer seemed unharmed, however his personality became much more aggressive, angry and child-like. Friends and workmates tried to convince him to seek help, but before he could a violent outburst was accompanied by a physical mutation into the super strong monster known as Red Rage.
Fuelled by anger Red Rage went on a rampage, taking down anything it saw as a threat, both to himself and to "innocents" he encountered on the way. Eventually he was stopped and the Benefactor offered to help work on a cure. In the meantime Trainer is occasionally released to assist his fellow Opal City Heroes in defence of the city in its direst emergencies.
Weakness: Trainer's intellect is almost entirely absent in his Rage form, leaving him practically mindless and easily confused and misdirected. has great difficulty distinguishing between friend and foe, though through the efforts of The Benefactor, this is improving.
My favorite of your designs.
One suggestion I would give is in reference to the torso. I would have made the curved slopes on the side progressively shorter in the back as you came down from the shoulders to the waist, which would have made his body less blocky. Regardless, I think this is an excellent build!
