Yeah, that's fine. I don't think I'm likely to go for anything beyond the pale of what you can explain with toxic waste and hidden psionic potential. Also, if you look at the strength chart, you can be hitting near the cap of +10 damage bonus and still have trouble carrying a passenger vehicle. It's the super-strength power that really gets you to a crazy place. Also, if you're in a more gritty/street level game, I think that tearing a steel fire door off its hinges and surviving a shotgun blast makes you plenty goddamned scary.
I have two character concepts that I can think of, which you're welcome to critique and tell me what works and doesn't work. Both of these are subject to further expansion.
A "terrifying avenger of the night" type. Like DD and Batman, spends a lot of time going after simple human scum and doing really memorable things to them.
Powers: Enhanced agility and healing factor, Phasing, a few low-grade gadgets
Turn-ons: Improvised Weapons, Shadows, Psychological and moral conflict, Gothic architecture, Symbolism, Soliloquies.
Turn-offs: Fearless robotic minions, Lasers, "Day Shift" superheroes, Proof that he isn't just an urban legend
This is a guy with an anger control problem, like Hikari mentioned. I suppose his powers are most likely psionic in nature. He can "see" the sins of others in a sort of aura sight. This ability showed up around puberty. But that isn't all. He can sort of hulk out into a demonic, gargoyle like form, which can also happen involuntarily if you piss him off bad enough. It's at the upper end of what you can physically do regarding physical strength and resilience, but it's almost certainly some really twisted and specific form of TK. He was raised in a Catholic orphanage, and for the most part thinks it must be some kind of divine judgement. Tends to be kind of a loner, not so much by nature as because he never knows what he might "see" when he's in public around a lot of people.
Powers: Sin-sight, transform into a demonic-looking juggernaut.
Turn-ons: Nuns, cathedrals, damsels in distress, terrible moral dilemmas, letting people know that they wouldn't like him when he's angry
Turn-offs: Villains to fast to land a punch on, punks who vandalize religious buildings, super-advanced technology, really impersonal forms of evil
