An idea I've always had for Marceline, and one that can be explored even further now that she's a champion, is to have her face off against top-tier characters and “Ace” characters that other players have (I'm open to both male and female rivals as opponents). Instead of relying on brute force or technique, she should use her knowledge and military expertise to overcome these challenges.
Scenario 2: Iron Will
This is an idea I’ve wanted to do with Marceline for quite a while now. It involves pitting her against an opponent who relies on mind games and eroticism, trying to break the Misfits’ leader’s fighting spirit and turn her into a submissive... But what they didn’t count on is Marceline’s devotion to her loved ones and her genuine love that goes beyond the sexual, which allows her to avoid falling into the adversary’s traps.
Pretty cheesy, I know, and not typical for this forum, but I love the idea of Marcy having a moment like that.
Spoiler

This is more of a comedic situation, and it’s one where her paranoia and the fact that she’s a 40-year-old boomer can really mess with White’s head, making her think everyone is out to get her and leading to hilarious situations where her distrust and lack of familiarity with the world of wrestling, especially with Law, come to the surface. It’s another setting for comedy, but I still think the belt lends itself well to this kind of thing.
That's about it. This thread is open on MD, both here and on Discord (godzillaoverlord), and I'm open to hearing ideas and discussing the topic. Also, I have no problem with Marceline facing off against men or women in any kind of hardcore scenario.
