Dark Cloud™

Have her own running series? Other than Target-X, I think she deserves just as much recognition as Wolverine.
 
This would be a great opportunity for Laura to get acquainted with the Marvel Universe. To meet new Mutants, other Superheroes, and possibly have her engage in some rather brutal battles. Perhaps she could win over a love, have a relationship that doesn't really, or necessarily, tie into her other story arcs.
 
Besides, she's a wonderful character. Who doesn't love her?
