M'gann M'orzz, better known as Miss Martian, is a Martian superheroine in DC Comics who debuted in Teen Titans (Volume 3) #37 in August 2006, created by writer Geoff Johns and artist Tony Daniel. Originating from Mars, she is a White Martian who fled her homeworld amid the civil war between the peaceful Green Martians and the aggressive White Martians. Upon arriving on Earth, she adopted the human alias Megan Morse and disguised herself as a Green Martian, claiming to be the niece of J'onn J'onzz, the Martian Manhunter, in order to emulate his heroic ideals while hiding her true heritage, given the prejudice against White Martians as conquerors.
Miss Martian possesses an extensive array of Martian abilities, including shapeshifting, telepathy, telekinesis, flight, superhuman strength, durability, invisibility, and intangibility, with her telepathic skills often described as exceptionally powerful. She initially joined the Teen Titans as a provisional member during the "One Year Later" storyline following Infinite Crisis, eventually earning full membership after demonstrating her loyalty in battles against threats such as Bombshell and the Terror Titans. Her empathetic nature and desire for acceptance drove her to form strong bonds with teammates, though she maintained strict personal ethics regarding the use of her powers.
A significant character development occurred with the revelation of her White Martian identity, which initially strained relationships with her allies due to ingrained biases but ultimately underscored her rejection of her race's violent tendencies in favor of heroism. M'gann has since navigated internal conflicts, including influences from darker future versions of herself and struggles with power instability, while continuing to serve with the Titans and as a liaison to groups like the Justice League in various continuities, affirming her commitment to protecting Earth despite her origins.
