115 is one of David Haller's sub-personalities.
During the Second Coming, the X-Men were besieged in San Francisco and Utopia, isolated under an energy dome by Bastion and attacked by waves of Nimrods from the future.
Cyclops, the leader of the mutant race decided so to use all of his resources on hand, and asked Charles Xavier to use the Legion as a weapon against the Sentinels. Xavier then launched the Nemesis Protocol, calling the personas to fight for Legion. 115 was the first personality selected during the battle, arriving just at time to save the overwhelmed and wounded Colossus. Her powers were soon assimilated by the Nimrods' defenses, and she had to leave her place to 762.
