A retroactive one. I wish Rogue and Marrow could have interacted like... at all during the later's brief time as an X-men, seeing how they were both former villains the team was reluctant to let in. Sure Marrow's crimes were harsher than Rogue's, but so were the circumstances of how she became what she was.
However if it would be done now, it just wouldn't fit anymore, since the world moved on and the circumstances in which it would have worked are gone.
Infact i think after the last 22 years, Marrow needs to be build from ground up again as if she was a new character, before she can develop or show any ties or relationships with the bigger named characters. She was gone from the team all of a sudden, nobody cared, nobody aknowledged it, nobody remembered. That's too much of an elephant in the room, to have her suddently be buddy buddy with the big name X-men. She needs re-introduction first.
You can't just have long established characters interact as if they had been good friends or know each other well, if the on pannel evidence contradicts or can't support it. That's bad handling of continuity and character progression.
I recall she and Kitty only really interacted during an X-men Unlimited story written by BKV. Though it was a pretty nice little story.
She never found out about Gambit's involvement.
Because her powers are bone blades and a healing factor, combined with an agressive brawler mentality and traumatic past?
Though if there was another cartoon involving X-23, i feel it would be interesting if Marrow had some non-genetic connection to her. Laura could need some named characters in her past who had a relation to her beyond tormentor, friend or family.
Of course that wouldn't work in the current comics continuity.
Indeed. They seem big on pushing the idea of a Wolverine Family, yet never bother with actualy showing them as that.
