Let me start by showing you the chart of all the rights for Marvel characters in movies:

So, this really helps one answer the question: Given the current movie rights, who CAN be on the Avengers?
Well, the better question would be... Who cant?

  • Sub-Mariner
  • Man-Thing
  • Spider-Man (And all his villains, minus Iron Patriot). It should be noted Sony is currently in talks With Marvel to merge.
  • Fantastic Four (And all their villains, minus the Kree)
  • Wolverine (And Sabertooth)
  • X-Men (And all their enemies, minus Quicksilver + Scarlet Witch)
  • Cable (And... Well, he's below)
  • Deadpool (He's made too many enemies to know who owns who)
  • Silver Surfer
  • Everyone else, Marvel Studios can use!
Any questions? Anything you want me to clarify? Ask!
