There has never been a superhero cast quite like Avengers: Infinity War and its as-yet unnamed sequel. All of your Avengers favorites will be in it — Iron Man, Thor, Captain America, Hulk, Black Widow, Hawkeye, Scarlet Witch, Vision — plus relative newcomers like Black Panther, Spider-Man, and Doctor Strange. Oh, and all the Guardians of the Galaxy are in it too. And Don Cheadle’s War Machine. And the Guardians’ new pal Mantis. And Paul Rudd’s Ant-Man. Infinity War is like It’s a Mad Mad Mad Mad Marvel World (or Cinematic Universe, in this case).

And there’s more characters being added all the time. This week, we got word that Tony Stark’s kid sidekick from Iron Man 3, played by Ty Simpkins, will appear in Avengers 4. At this point it seems like almost every character that has ever appeared in the Marvel Cinematic Universe is going to play a role in one of these two Avengers. We’re not 100 percent certain Forbush Man is in there, but we wouldn’t rule it out.

Are there any MCU characters who won’t show up in Infinity War? Actually yes — but not many. Still, we found ten candidates who are almost definitely not appearing. (Although, Marvel’s plans do sometimes change, so just because an actor has claimed they’re not contracted for Infinity War doesn’t mean they won’t be in three months.) We did our best to weed out anyone who’s been rumored to return, even if those rumors seem pretty far fetched to us. (Like Liv Tyler’s Betty Ross, last seen almost a decade ago in The Incredible Hulk.) Just to make it tougher on ourselves, we also left out any character who was definitively dead (because, duh, dead people don’t show up for sequels). So here are ten characters who almost certainly won’t be sharing the screen with Ty Simpkins (sorry dude, nothing personal):
