"Child's Play" is a 1994 Marvel Comics crossover storyline featuring the New Warriors, X-Force, and the Upstarts.
Accordingly, during this story, Magma divorces herself from the Amara Aquilla persona and decides to uncover her origins as “Alison Crestmere.” In the process, she demands Empath keep his distance.
Deceased members of the New Mutants and the Hellions not available for capture include: Cypher, Warlock, Jetstream, Beef, Bevatron, Catseye, Roulette, and Magik.
Sunspot was a surviving New Mutant who was not targeted by the Upstarts because he and Locus were lost in the timestream at that time.
Rusty and Skids, also former New Mutants, were not targeted in the Younghunt, likely because of their affiliation with the Acolytes and were under Magneto's protection, far from Earth on Avalon.
