It felt like about time for one of these kinds of threads. And, like it says in the title, your assignment is to pick your own Avengers lineup out of characters that Marvel Comics once did, but no longer has the licence to use. Bonus points if they actually interacted with Earth-616 at some point (which is actually a surprising number of 'em).
My personal picks—admittedly a bit small, for the moment, anyway:
•Conan the Barbarian. This one practically happened in one “What If,” actually.
•The Doctor. Gotta love Marvel Comics UK.
•Optimus Prime. Give him Cap’s shield. Plus, he can double as a transport.
•Snake Eyes. 'Nuff said.
…for the five to fifteen minutes the team would likely stay together, it’d be unadulterated awesomeness. They probably wouldn’t take any guff from Spider-Man antagonists, either. What with their collective store of brains, savvy, and ability to stab.
Throw in Keifer Sutherland for a handicap match and Old Man Chuck, who apparently has already taken a few too many to the head, will be readily outmatched.
