I'll try and beef this up a bit later, but this is the basic timeline I see for M'gann.  If anyone has any objections, recommendations, etc, feel free to send them to me either here or in a PM.  Thanks!  Once this is done I'll throw it into her profile in the Character Repository.<br/><br/>2005 - M'gann M'orrz flees Mars on one of her uncle's trips to and from his adopted homeworld, and quickly establishes herself as a sidekick to Martian Manhunter<br/><br/>2006 - Darkseid attacks for the first time, and M'gann does what little she can to help defend the world against his forces alongside her uncle J'onn.  Both she and he survive.  Later that year however she ends up captured by Lex Luthor and experimented on for three months until Orin, her uncle J'onn, Dick Grayson known as Robin at this time, and Booster Gold save her alongside other members of the League.<br/><br/>2007 - Decides to help Aquaman when he asks the League for help reclaiming his throne.  Since he was part of the team that saved her, she felt it was only natural she return the favor in some small way.  Even if he hadn't, it was the right thing to do in any event.<br/><br/>2008 - Despite the League disbanding when it's discovered Batman had contingency plans to deal with the League should they ever turn hostile, which Ra's Al Ghul attempted to use against them, M'gann remains in Atlantis, doing what she can to help Orin stabilize his kingdom.  Her psychic powers are a massive help in the rebuilding process, both literally and otherwise.  That and she found the culture and history to be quite fascinating.  Orin and her become close, she seeing him as an honorary uncle figure and a wonderful teacher on all things Atlantian.<br/><br/>2009 - Returning to the surface, M'gann rejoins her uncle when the League faces off against Brainaic.  Orin and her are still good friends and remain in contact despite the distance between them.<br/><br/>2010 -  Atlantis falls off the grid in every sense of the word.  She tries to find out why, despite the Justice League sending her down anyway to do just that, but can't get close because of all the raw rage and pain that radiated from the underwater realm like a sickness.  She returns hours before Darkseid is due to arrive, and tells them that something's wrong under the ocean.  Soon after, before they can mobilize a response, the League falls, and M'gann's darker nature and impulses start to surface when her uncle dies right in front of her.  Unleashing her full telekinetic might for the first time, the Apokoliptian super soldiers that killed him are shredded apart.  Her first comatose victim, having been on the receiving end of her mental barrage before having information forcibly removed from his brain, also surfaces later that year in a Metropolis hospital after Darkseid's defeat.  Meets and helps Superboy later that same year.<br/><br/>As for her return to Atlantis, it is postponed indefinitely because of the chaos Darkseid's attack left behind in its wake.  With so many heroes and heroines alike dead or MIA, many of the world's supervillians and common criminals alike ran amok.  The world needed time to heal on top of that, and there was only so many heroes to go around.  But she had a personal reason as well for not returning to Atlantis.  Despite her shift in personality, M'gann didn't want Orin to see her darker nature, to have his image of her younger, more innocent, carefree self shattered by the darkness she had been all too happy to embrace to survive the onslaught.<br/><br/>2015 - King Orin returns to reestablish contact with the JLA in the early days of February, as well as find M'gann M'orzz, but finds out the League has fallen and M'gann has changed dramatically since their last meeting.  After an emotional heart to heart, she breaks down in front of him and he does his best to comfort the young woman he considers an honorary niece.<br/><br/>There, hopefully that helps.  ;D  Sorry it took so damn long.
