Well I'm kinda a big guy, I think as a hero dude I would be tall, broad chested, surrounded by many secksy woomanz, perhaps long flowing blond hair, cobalt eye's that seem to penetrate your very soul, and chiseled features, a pearly white smile and firm pecks and core... hm.. oh, but I wouldnt run around in my underwear, i'd be wearing This : http://www.abbyshot.com/products/ps-leather-stampede-duster.php or any other secky suit on that site. yes... I like this idea
Oh and powers, yes, they is important, um, I'd be kinda like Alex Mercer, really cool concept if you think about it, compressing my biomass and consuming more biomass, using my absorbed flesh as a weapon or tool, ageing isnt an issue, ad all i need is one cell alive and i can consume and reform, Closest thing to immortality without actually being a god.
