Vision: No relation to Ultron at all, he was an android created by Project: Pegasus who was originally supposed to be their guardian, but eventually evolved to become a fulltime hero.

Domino: I've already told you about her.

Hulkling: Mutant who was exposed to a small dose of Gamma Radiation, which gave him strength close to the Hulk's, but he maintained his shape shifting abilities.

Wiccan: One of Dr. Stange's (who I still need to add) former students who had mastered every spell he was told to learn, and eventually used them to become the hero known as Wiccan.

Giant Man: Scott Lang idolized the hero Yellowjacket for his growth serum using Pym Particles, so Scott got a sample and manipulated them until he could control them without using a suit, and he became the hero Giant Man.

Wonder Man: After losing his job, Simon Williams went to his successful brother, Eric, who offered him a spot as a guinea pig in a new AIM experiment. He regretfully agreed, and was transformed into Wonder Man. At first he was a villain, but later reformed himself.

Iron Fist: Not so sure about him yet.

Cannonball: Just a mutant

Goliath: After Luke Cage left the Avengers, he got his hands on some Pym Particles as well, and used them to become the hero Goliath. He was offered a spot on S.H.I.E.L.D.'s New Ultimates, and after a while he accepted.
