Miss Martian is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Comics franchise.
M'Gann M'Orzz (pronounced muh-gann muh-orse), aka Megan Morse, aka Miss Martian is a member of the Teen Titans. She is a White Martian who used her shape-shifting powers to take the appearance of a humanoid green Martian. This decision was motivated by her fears of rejection from other heroes, as the White Martians are widely considered villains. To try and amend for her species' crimes, she uses her shape shifting, telepathy and telekinesis to fight evil. She claims to be the niece of John Jones/Martian Manhunter, although this has yet to be proven or could simply be a term of endearment.
