Thinking outside the box, because I play Showdown and stuff like Kizaru = Pikachu isn't enough for me:
- Charizard X based on Zoro with Santoryu being flame charge, iron tail, and dragon rush.
- Mega Aggron based on Kaido using meowstic as Bao Huang to set up the screens.
- another mega as Kaido, Gyrados, where I bait fighting and ground for intimidate until it's safe to set up "hybrid" with dragon dance.
- Blaziken is actually Doflamingo because in doubles, using hone claws under mat block is so devious
- tag team Smoothie and Amande with tsareena and pheremosa
- well, Mamoswine is clearly Jack
