I feel like there are multiple ways they could do this.
I would personally really prefer if they still introduced a bunch of the classic characters as minor antagonists in upcoming projects. Something like:
- Melissa Gold as an associate of Titania in She-Hulk
- Abner Jenkins as a minor antagonist in Armor Wars
- Karla Sofen getting the Kree artifact moonstone in The Marvels
- Erik Josten getting Pym Particles in Quantumania
- I'd be fine with replacing Fixer/Techno with Ghost
- Of course having Zemo as the leader
- Maybe adding Taskmaster
Alternatively they could combine it with the Dark Avengers, in which case it would be what Val is building
- U.S. Agent
- Black Widow II (Yelena)
- Abomination
- maybe Detroit Steel (Hammer) or some other armored villain from Armor Wars
- maybe Taskmaster could mimic Hawkeye?
- maybe Mordo?
I'm not sure who else would be good fits here. I don't think we really have good fits for "dark" versions of Thor, Hawkeye, Scarlet Witch, Vision, Falcon, War Machine, Black Panther, Captain Marvel, Ant-Man, etc. yet who are still alive?
I wouldn't really mind such a team, but I would prefer they not be "The Thunderbolts".
Third possibility is just making it a group of existing villains without considering the comics or whether they make a good Avengers parallel. That would probably combine characters like
- Zemo
- Abomination
- Ghost
- Taskmaster
and who knows who else..
I'm curious to see which way they'll go. I'm hoping for the first, but I'm afraid it's not very likely..
