Earth's Mightiest Heroes. Originally founded by Iron Man, Thor, Hulk, Ant-Man and the Wasp, the Avengers have been the premiere super-hero team of the Marvel Universe ever since. A full list of members unrelated to the X-Men would be too numerous, but presently:
The Avengers include the current versions of Captain America, Thor, Spider-Man, Vision, Hercules, and the Wasp.
U.S. Avengers, the strike force for American Intelligence Mechanics, includes Roberto Dacosta, Cannonball, Squirrel Girl, Red Hulk II, Enigma, and Iron Patriot III.
Rogue presently leads the Avengers Unity Squad with Cable, Deadpool, Quicksilver, Wasp, Human Torch, Synapse and Doctor Voodoo.
