Marvel’s Avengers’ enemy variety was severely lacking as far as how dynamic or varied its pool of Marvel factions and villains could’ve been, but AIM (Advanced Idea Mechanics) wasn’t an inherently bad choice as its bedrock. An endless horde of yellow automatons surely isn’t the most extravagant or thrilling enemy, and yet there are few factions who could viably go up against an entire Avengers squad anyhow. Even if players’ teams in Marvel’s Avengers consisted of Iron Man, Hulk, Spider-Man, and Black Panther, AIM holds up decently well whereas any random assortment of human enemies would be wholly unrealistic.
