But his answer seems to indicate he thought you were asking about Marvel characters in Transformers. Obviously, there's not going to be a Spider-Man vs Megatron two-pack. But what Marvel characters appeared there? Circuit Breaker is the huge one, and Death's Head would be close behind. There's also the aforementioned Spidey, Nick Fury, an off-hand comment about Godzilla, and the Savage Land factoring into the Dinobot origin. That's it, so far as I can recall (though Robot Master could be a bit iffy, since he's based on real-life Marvel editor Danny Fingeroth). Everything else is owned by Hasbro. Even the Neo-Knights. Heck, I think even G.B. Blackrock would technically be Hasbro property; unlike Circuit Breaker, he didn't first appear in Secret Wars.
If Hasbro really wanted to push it, I believe Circuit Breaker appeared in TF as Josie Beller prior to her superhero appearance in Secret Wars.
Damn, that's another Hasbro Marvel question that would've been good: 3.75" or Legends Death's Head.
