I was rereading CW#4 and it hit me.
If they can clone Thor, then they can clone anyone, including Spider-Man
So all Spidey has to do is appear in public and say that Iron Man's been cloning heroes and giving them false public ID's to make it seem like certain heroes were on board with Regristration when they really weren't.
All he'll have to do is come up with a Peter Parker to stand next to him and complete the illusion, a powerless Peter Parker that claims he's been in the negative zone all this time with no clue what was going on or who was impersonating him. I'm sure the Anti-Reg side has a shapeshifter or something.
Anyone think there's anything to my idea?
