History
Marrow's history followed a similar history to her Prime Universe counterpart. A century after the Twelves, she married Gambit and traveled to X-World for their centennial celebration. When they attempted to use a strange device to restore Xavier, Marrow was one of the mutants who contributed her energy before it was revealed to be a ploy by Apocalypse.[1]
