10 Comic Characters You Won't Believe Joined The Fantastic Four
7. Medusa
The Queen of the Inhumans and sister to Crystal, Medusa is one of the most politically powerful people in the standard 616 realm of Marvel Comics. First appearing in Fantastic Four #36 as part of the antagonistic Frightful Four group, she later formally joined Marvel's First Family in Fantastic Four #132.
Like her sister Crystal, Medusa replaced Sue Storm on the team while Sue took some time out to care for her catatonic son, Franklin Richards. As a member of both the Inhuman Royal family and the Fantastic Four, Medusa attempted to build a relationship between humanity and the Inhumans. Unfortunately, her efforts failed, and the Inhumans relocated to Attilan to avoid human aggression. Later, she would joined Scott Lang's version of the Fantastic Four to help arrest Doctor Doom.
Medusa has always been a helpful ally to the Fantastic Four. Through her connections with the Inhumans and the Illuminati, she has always been a force for good.
