Uncanny X-Men #346 (8/97) - Marrow and Callisto arrive in Manhattan to kill mutant-hater Peter Gyrich. Marrow looks more human now, and has a full head of hair. With the exception of the bone arsenal she carries on her back, Marrow appears to have no bones growing out of her. Spider-Man stops Marrow's murder attempt, but while they are squabbling Callisto is seriously injured when she takes a blast from a Prime Sentinel meant for Marrow. Spider-Man becomes the first upworlder to try to make Marrow consider the consequences for her actions and to not let her past dictate the person she will become. Marrow leaves with Callisto, apparently contemplating Spider-Man's words.
