[quote=@Fallenreaper] Depends on how radically different you want him? You want to be technical, Rach has a bit of magneto influence in her design in her earlier stages as well as Riddic from Pitch Black, and a few others. Like Dedonus said, keeping away from the main distinctions that made the Hulk recognizable is a key thing, from background to personality. A few things to consider: How his powers work- In the comic, the angrier the Hulk got, the tougher and stronger he got. What if your PC's 'Hyde' didn't draw from that source? What if it was like he absorbed damage and instead, used that to increase his power level to a higher degree? Maybe he has a fixed right of power that could be universe and it grows as a battle prolongs? This also include triggers. Maybe blood or injury or even someone else's aggressive emotions stir his inner beast? Banner's was pretty much if he got anger, they were all screwed. Personality of your Jekyll- Banner was emotionally reserved and socially withdraw through out most his life, what if your guy didn't start off that way? He could be a cocky, smartass with a chip on his shoulder. Also, I think Banner was specialized in his work, what if your PC wasn't? Just some poor smook that got infected and suddenly affected in a way he never expected with no way to know how to fix it at first? Could've been a janitor at a high tech lab until something got loose or he was tossed into a bunch of chemicals, the right ones including a mysterious test one, changing him forever. Cause- How this happened. Gamma is out, unless you can manage to make it radically different from the comic which is very hard. I suggested chemicals, maybe a drug which I know is how meta humans are popping up (maybe he got a bit of the meta human drug, tried to alter the effect and tested it on himself?), curse, infected by demonic blood, maybe a sleeping DNA trait not from him but a old relation that passed through the gens before somehow becoming active? Maybe he draws power from the fear his image inflicts? Past- Did he have a happy childhood? Maybe both his parents are alive and well, encouraging and happy for him? Maybe he's married or worse, married and divorced twice? Doe he have brothers or sisters? Raised by his uncle, or someone he knows? Etc. Appearance- Make him look the same, but instead his eyes or another key feature betrays that his alter ego or whatever is in control? Maybe it's more beastly or demonic than human? You could mix the two concepts together, Jekyll and Hyde and the Hulk, and see what you get? [/quote] I already know these things. Plus Banner wasn't initially quiet and reserved, that was really a side effect of the Hulk. Before that he was a (Hah) nerrrrd. I already have brainstormed a couple of possible sources and will get to that during my lunch break.
