Joining the Teen Titans (2006)
When she first joined the Teen Titans, M’gann’s teammates didn’t understand her, and she soon left the group. On her own, she operated as a hero in Australia, but returned to the team during an adventure in which the Titan called Bombshell was revealed to be a traitor (Teen Titans vol. 3 #37-41). M’gann’s White Martian nature was revealed during these events, but her efforts to protect the Titans convinced them she could be trusted. She was welcomed back onto the team.
The Titans later fought a group of Super-Villains Deathstroke had recruited specifically to battle them, in 2007’s Teen Titans vol. 3 #43. Due to her fire-based abilities, the villain Sun Girl proved a particular problem for M’gann. A time-traveler, Sun Girl claimed M’gann’s actions in the future would lead to the surviving Martians’ enslavement. Miss Martian eventually defeated Sun Girl by forcing her underwater, dousing her flames. It was later revealed that in Sun Girl’s future, she kept M’gann as a personal slave.
Titans Tomorrow (2007)
In 2007’s Teen Titans vol. 3 #51, the Teen Titans met another group of villains: themselves, from the future. This “Titans Tomorrow” team included an older version of M’gann who now used the name Martian Manhunter and embraced her White Martian appearance and aggressive nature. M’gann was startled by her own potential for evil. During the battle, Miss Martian beheaded her future self, but the older M’gann saved her own life by transmitting her consciousness into her younger self. Afterward, M’gann would frequently wrestle against the influence of her older self.
M’gann established a human identity as “Megan Morse,” attending Arizona’s Wolfman and Perez High School. But after repeated evidence that her dark future self could still influence her, she decided it would be safer to leave the team and find a solution for her divided mind on her own. She left in 2008’s Teen Titans vol. 3 #62.
Final Crisis and Beyond
A more stable M’gann later appeared when she disguised herself as the hero Star-Spangled Kid and infiltrated the Dark Side Club in 2009’s Terror Titans #1-8. Under the control of Darkseid, the club was a safe house where he kept children and teenagers whom he brainwashed to serve his will. M’gann used her telepathy to free the kids and led them against the Terror Titans. Victorious, they left the Dark Side Club and M’gann helped Earth’s heroes and the agency Checkmate against the threat of Final Crisis in 2009. When Final Crisis concluded, M’gann rejoined the Teen Titans as a full member in 2009’s Teen Titans vol. 3 #69, though she took another leave of absence a few months later.
