What would you have, and what would you use them for?
Personally, I'd have super strength, super speed, and invulnerability (With an Achilles' Heel, of course). Using these, I'd take some awesome metals and forge myself a gigantic sword or two, and a suit of armor, maybe like Sauron's (LotR), or the armor you get when you get a cursed sword in Lineage.
After this, I'd kinda just roll around the world, saving people, stopping crises, and in general being a bad-ass superhero.
Now the question is, what would you be?
