M'gann is 58 Earth years old, which makes physiologically makes her the Martian equivalent of a 19 year old (approx.). When she's interacting with people who are unaware that she's Martian (eg: the kids she counsels), she presents herself as a human woman in her mid-twenties.
As an adult in the Titans of Tomorrow... Today! storyline, M'gann's default physical form is that of a White Martian having embraced her heritage (and Martian physiology reflecting their state of mind). To compensate for her pyrophobia, adult M'Gann wears a forcefield that protects her from flame.
Miss Martian's natural White Martian form. Miss Martian's true appearance is that of what most humans would consider an inhuman monster, with white skin, long limbs, and a hunchback.
In Action Comics #1057, Superboy and Miss Martian officially start a romantic relationship after being together in Young Justice, a change that might surprise comic readers.
Because her White Martian heritage had brought on persecution, she portrayed herself as a Green Martian — something she did for years. M'gann shortened her hair as she aged, and in a later attempt to better connect with her heritage, she left her skin white and tried going bald.
She wasn't comfortable displaying or telling others that she was actually of the White Martian minority, and changed her color to “fit in.” Her Martian humanoid form also mimicked the Hello Megan's hair symbolizing her desire to live the picturesque life, as picturesque as the life can get basically.
Having become obsessed with Earth TV during her time on Mars, M'gann started emulating the mannerisms and behaviors of the main character in her favorite program, Hello Megan. She even used the catchphrase from the show, "Hello Megan," as her own during the events of Season 1.
Her clothing is simple and appealing in looks. Miss Martian's body is green colored where she wears special Miss Martian Costume which includes white shirt with red belts and blue skia rt with belt on the waist.
Super Strength: She possesses superhuman strength that allows her to lift in excess of 100 tons with little effort. Martian Senses: M'gann is said to possess nine different senses. Martian Vision: M'gann can emit beams of concussive force with damage potential in excess of 1000 tons of TNT from her eyes.
They struck up a relationship shortly after M'gann's relationship with Superboy ended. M'gann felt La'gaan made her happy with herself. La'gaan was uncomfortable with his "impure" appearance, and the way it sidelined him for most missions.
In Season 2, both are sidelined. Kid Flash and Artemis have retired, Aqualad quit the team and turned evil (or so it would seem) and Robin has become Nightwing.
From biological point of view, Megan can't have children with Conner since they are different species (she is Martian and he is human-cryptonian hybrid).
The two heroes broke up between season 1 and season 2 of Young Justice, after Superboy objected to M'gann using her telepathy to mess with the minds of supervillains. Given how his own memories had been altered by the scientists who created him, he had strong opinions on such things happening to other people.
He grew up on an animal sanctuary in Qurac, with his mother. After an accident Miss Martian was forced to give him a blood transfusion which resulted in him gaining the ability to shape-shift into any animal. After the death of his mother, Beast Boy is now under the care of Miss Martian, who he addresses as his sister.
Martian Manhunter is the uncle of Miss Martian (and now also of Beast Boy?), who both are Martians from Mars. I thought a bit about the powers of the three related characters and noticed something important: All three are immortal because of their shape-shifting powers.
In an all out brawl, Raven may be more powerful, but she's often hesitant about using her powers so she gets taken out sometimes that way. Miss Martian has a multitude of abilities. It'd be a tough fight.
Miss Martian, aka M'gann M'orzz (who also goes by Megan Morse), is a White Martian who travels to Earth and becomes a superhero. She has similar abilities to Martian Manhunter, including shapeshifting, telepathy, telekinesis, and superstrength.
Wally was more interested in Miss Martian, but his frequent arguments with Artemis was the spark of romance. The time skip between seasons one and two upgraded Wally and Artemis' relationship. Much like in the comics, Wally retired from Kid Flash to attend college. He and Artemis lived together.
By the end of Season 1, he started dating his teammate Artemis Crock after they slowly started to fall in love during the season. Their relationship lasted until the end of season 2 where Wally died saving the earth.
