Paste Pot Pete and the Trapster are the same guy. (After a few appearances in Strange Tales he realized he needed a better name and a costume.) I think the name change came in FF #36, the first time the Frightful Four got together. The evil FF had three previously seen characters: The Wizard and Pete, who had teamed up in Strange Tales, and the Sandman who up to that point was (I think) just a Spidey villain. The fourth member of the team was a brand new character, the mysterious lady known as Medusa. When the Wizard found her she wasn't living with the Inhumans. Instead she was living in a cave, wearing a yellow dress, and using her hair to toss the locals around. (Gosh, I love that old Lee and Kirby stuff!) I was talking about this with my son the other day. Now that so many Marvel characters have been (or soon will be) on the big screen, it would be cool if they started to tie it together into an onscreen Marvel universe. Having the Torch in the next Spidey movie would be a good way to start.
