I see a few that could work.
Replace Hulk with either Sabertooth or Blob. Or a teamup of the two.
Hawkeye could be replaced by Gambit.
Replace Red Skull with Mr. Sinister.
Anyone else crucial that Fox doesn't have?
This is blasphemous...
Old man Logan is easily my favorite story arc, and all the aforementioned would ruin this classic tale, the original story was so classic, and these proposed changes are just the start...
I would miss mechanic ultron, venomous T. Rex, and who could forget spider bitch.
No sir, I don't like gambit filling in, especially if it's Tatum...
What did I tell you people?
This is a fine way not only for Jackman to bow out of the franchise but for Fox to use up the last, best Logan story from comics before rights go back to Marvel someday.
Time for X-23 to step up to the plate.
This would be a nice ender for jackman
