Vision
BlackKnight
Black Widow
Swordsman (joined Avengers #20, membership taken away when discovered he betrayed them. Reformed and reinstated. Recommended full membership from Thor)
Mantis
Moondragon
Beast
Hellcat
Two Gun Kid (My thought he was granted Avenger status when he went into battle with Thor and Hawkeye. Possibly even Moondragon granted full status.)
Captain Marvel (Ms. MARVEL, Warbird)
Wonderman (Accepted on probationary member Avengers #9, betrayed team and status was taken away. Reinstated as probationary member after battle with Gravitron. )
Falcon
Jocasta
Tigra
She Hulk
Spectrum (Captain Marvel, Pulsar, Photon)
Starfox
Mockingbird
Iron Patriot (Ironman, War Machine) (Was told during first Secret Wars though on leave he was with the Avengers, this may have given him official status or just to clarify among the other heroes. It was revealed later on Prof Xavier and Reed Richards knew of Ironman's identity.)

Doctor Druid
D-man
Mister Fantastic
Invisible Woman
Gilgamesh (Hero, Hercules, Forgotten One)
USAgent
Quasar
Espirita

Sersi
Spiderman
Stingray
Rage (status in question. When found out he was underage he had his membership downgraded to Avenger in Training. Later he hijacked a quinjet and he was expelled. It might have been reinstated after Morgan Le Fay battle.)
Sandman (left in a huff, has been stated in other posts he was only a reserve, never a full member. My thought an Avenger is an Avenger. Plus there were two times he status was upgraded to full when filling in during the substitute Avenger status was implemented. When the Avengers battled the Sinister Six Captain America offered him reinstatement. His mind was scrambled by the Wizard. This has never been addressed.)

I listed, but wasn't sure of Cho and Stature due to there age. I didn't list Agent 13 and Agent Hill, thinking it was more of an assignment. Ironman (Teen Tony, though listed as honorary I thought had full status. I felt the original Captain Marvel was given reserve status.)


That gives them 100 members.
