Iron Man/War Machine suit. Or maybe some kind of alien symbiote a la Venom or Carnage, provided I can avoid the negative psychological effects. I'd avoid non-powered armour suits though, for one simple reason. They'd be really, really heavy. Like, immovably heavy for most people of average strength.
I'm also avoiding MJOLNIR armour because the idea of a powered suit that amplifies my actions to the point that I'll break my arm trying to wave isn't my thing. Especially since the resultant pain spasms would shatter all remaining bones in my body. Damn lack of genetic/bio-mechanical augmentation...
Maybe power ranger armour... c'mon, it's flexible and bulletproof! [small][sub][small][sub]And attractively tight-fitting! [/sub][/small][/sub][/small]
