David re-manifested in the physical world, although his core David personality had been imprisoned in his mindscape by his other personalities, allowing the more malicious personalities to take turns controlling his body. One of these personalities killed and absorbed the mind of a young girl, Marci Sobol, who became another personality within Legion. David was discovered by the New Mutants as they investigated a possible mutant case in Westcliffe, Colorado. David absorbed Karma and Magik into his mind. As the rest of the team fought a losing battle against various personalities that seized control of Legion's body, in his mindscape Karma and Magik destroyed other hostile personalities. Eventually they found the Marci personality, who led them to David's imprisoned core self. By freeing David and helping him reassert control, Karma and Magik saved the rest of the team and were restored to their bodies. David was detained by the X-Men and put in the care of Professor X, Doctor Nemesis, Danger, and Rogue.
