Fan Casting Miss Martian in Martian Manhunter

Daughter of a Green Martian and a White Martian, M'gann M'orzz was one of the only (along with another sibling) to inherit the traits of a White Martian. It is revealed throughout the film that his first contact with Earth (and with J'onn, albeit from a distance), was during the events of the Invasion of Mars, even though he did not support the Hyperclan's violent acts, deciding to hide on Earth. Despite this, she is willing to help Martian Manhunter, believing that she must also protect that planet now. At the end of the movie, it is revealed that J'onn was actually her uncle.
