a well fitted sublimated superhero/villain zentai without the hood (face coverings put me in claustrophobic/panic/rage-destruction mode). Always wanted to try something like that which would double as both a costume I could go to the geeky conventions in, as well as fetish gear.
It would have to be Eddie Brock/Venom because I enjoy darker colors, and the image of him being chained above a fire while his skin tight symbiot-suit melted off to reveal he was going commando helped me realize my attraction to men at a rather early age. It didn't hurt that a lot of the artists that drew him gave him a rather generous bulge. He still gives me nice dreams.
