Spider-Man: Decide who your Spider-Woman is and get rid of the rest. Miles can stay. Spider-Boy is gone.
Captain Marvel: Genis and Ms. Marvel can stay. Lauri-Ell and Phyla are gone.
Wolverine: Laura? Gone. Daken? Gone. Gabby? Gone. Reine? She can stay. Reine can stay because she shares enough stuff with Wolverine to be similar but different enough that she doesn't take anything away from Wolverine. What is her continuity situation anyway?
