!!! Helloooo :D
I would /gen love to write it all your Odyssey Duo takes are so peak, I was actually the one who sent the anon ask about your Wifies design (I am scared of people). But the idea of Wifies being a diamond player is so peak, I never really considered it because combat isn't really his thing, but I think that would actually make the fights way more interesting? It would also probably give him some major character growth (for better or worse) since he would be actively engaging in killing, something we don't really see Odyssey Duo do a lot.
Plus just like, Odyssey Duo is basically always in conflict/on the run, so seeing them in a static place like the mafia headquarters (which, the diamon players live in luxury as well) would be such a different pace and put them in a very different position. Like, they're living the domestic life, and then Wifies just goes out and kills a guy occasionally. Plus, forcing Parrot to grapple with the fact that even if he isn't actively engaging in murder he is still killing hundreds of players through his plans and tactics at Ash's side? Peak. Wifies would 100% bring that up any time Parrot criticizes him too, since Technically Parrot would have killed *more* people than he had.
I dunno, there's just so much to be done with it, I could probably come up with something more coherent in an actual google doc. I'm very new to the Unstable Universe fandom (I currently have one fic and one chapter lol) so this is most definitely something I may do <3
