Huh. I had no idea that version of Metallo existed. It is interesting to think that Stan Lee may have borrowed from Golden Age Metalo for Iron Man, and now HE is the quintessential man in a metal suit. Although I really kinda doubt it.
Wait, that's not even what I meant! Don't twist my words! I meant they could exploit GL's weakness to the color yellow. No, it wouldn't make him completely ineffective, but it would still hinder his ring's effectiveness if Iron man painted his suit yellow and..um.. convinced Hulk to wear something yellow, I suppose. A day of prep could arrange that.
I know DC tries to make us forget about GL's weakness against yellow, but I WILL NOT.
What weakness to yellow are you talking about? Do you not know that GLs havent been weak to yellow for a long, long time?
