Suggest a paring for Mewtwo (Patreon)

I did this sketch 2 months ago inspired by Diddy Kong's side+B special from Smash Ultimate, but I decided to better not drawing Diddy cuz seems he's not an adult.

So why not reading suggestions from my patrons :p Say, what medium size character would you like to be in there? Copyrighted characters only. (The pose might result a bit different)

Comment your ideas and this time,  I'll choose the most I like.
