That is quite an interesting theme you got there. I dig it. Which subforum will it be on?
Oh, and I got a possible idea of a superpower, that I kinda got from my character on another RP: What about a man that has the powers of mechanopathy (can feel and manipulate machines) and electrical manipulation (to a limited extent)? The downsides would be that chronic engagemwnt in this activity slowly rips off parts of the man's human personality and way of thinking, slowly turning him into an automaton of his own. And obviously, intensive short-term use of his powers can cause extensive neural damage, and mild (possibly temporary) encephalopathies.
