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 Falcon, 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 Toni Ho.
Rogue presently leads the Avengers Unity Squad with Wasp, Scarlet Witch, Human Torch, Synapse and Doctor Voodoo.
