Re: Characters you'd like to see in future Avengers movies?
The Masters of Evil make the most sense to me. There are a few members that are confirmed for a movie or have been featured in one. Abomination has been featured. Crossbones is confirmed for Captain America 2 (and the actor has a multi-film contract). Characters like Baron Zemo, Enchantress, and Executioner could easily feature in Phase III films.
