4. Malekith-Fighting Armor
I mean, not much use for this one anymore I guess, now is there?
This armor came about in a storyline from the Marvel Now iron Man run. In that story, Malekith the Accursed got bored of messing with Thor and decided to take a crack at Iron Man. After the first fight went badly for our tin terror, he realized something: pure Iron burns magical creatures. Like dark elves. Which Malekith is one of. So he built this big hulking knife monster of a suit made of pure iron and went to town on the dark elves.
In a brutal, show of absolute badassery. I've always loved this armor and Tony might need to fight magical creatures at some point in the MCU. I mean, Asgard may be gone, but the other eight realms are alive and kickin', including Svartlheim, land of the Dark Elves.
Might be a mighty need for some Iron boots to go ass-kicking sometime soon.
