At this point just Hulk (I'd have taken the Norton or Bana version really but Avengers will do), Doc Ock from Spiderman 2 and maybe Green Goblin from the first film.
Im sure someone mentioned Mystique & Phoenix from the XMen movies. A realistic Storm (w/ 70s outfit) would be killer. Im surprised HT didnt make a movie version of Mary Jane.
Comic versions of the Avengers and X-men, and a large variety of their rogues gallery.
If I could get realistic 1/6 comic versions, I wouldn't even collect the MMS line anymore.
1/6th Modern Thor would be amazing. I've been trying to find ideas on customizing MMS Thor into the modern...but haven't nailed down any materials to use.
A DX Michael Fassbender Magneto from first class. One version with the blue and yellow suit and the silver helmet and another with the full out Classic Red Magneto outfit when they break Emma out and the end of the film. I would be willing to drop at least $250 on that.
