Just a quick minifig of Tony Stark's Aqua Suit. Not really from any movie, but it bears a striking resemblance to the older comic-book ones.
About this creation
(I don't paint my Lego, and I've never gotten around to using any of the Minifig Decal Services yet)
This is a low key build of Aqua Iron Man with a flare and harpoon gun. (Minus the harpoons. Sorry, but I installed them on Xalos #2 instead.)
His helmet is made using a red star wars rebel/fireman helmet and this weird visor I found. I think it's a Mega-Bloks peice, but oh well. The orange body is from an Exo-Force set.
This is the back. He has a tank for breathing.
I would have also added flippers, but I only have one.
