Green Lantern and Iron Man in "Exterminated!"

Here's another in my series of Iron Man/GL covers.  I usually have them at odds so this time around I thought I would have them working together against a common foe.  I like the idea of these two together - Test pilot granted the most powerful weapon in the universe and billionaire genius who builds the ultimate armor.  I just feel that these two strong personalities would butt heads even when they have to join forces.
