9. Moondragon

Moondragon is the super-name of Heather Douglas. She first appeared as Moondragon in Daredevil (vol. 1) #105 in November of 1973, having previously first appeared as Madam MacEvil in Iron Man (vol. 1) #54 in January of the same year.
She first joined the Avengers in Avengers #151 in September of 1976, having previously been given probationary membership in Avengers #137 in July of 1975.
Born a human, Moondragon was raised and trained on Titan by the monks of Shao-Lom, having been taken there by Thanos’ father Mentor when Thanos killed her parents on Earth. As a result, she developed a number of powers and abilities, including enormously powerful telepathy; low-level telekinesis; incredible martial arts skills; and great adeptness in genetics, engineering, and piloting starships.
And now we move on to an insanely powerful character, who is undoubtedly the most powerful female ever to join the Avengers.
