Shadow Mario vs Wario - Ehh, Shadow Mario is Bowser Junior anyways

Cappy vs Luma - Maybe if I do like a 3D Mario Games battle Royale with their representatives, like Cappy for Odyseey, Luma for Galaxy, FLUDD for Sunshine, not sure for 64 and 3D World

Rosalina vs Kirby (Crossover special? (bpf)) -This is not Mario vs Anything, but if I'm gonna make a crossover special, maybe it's Sonic the hedgehog (Mario and Sonic at the Olympics Games) vs Someone in Dragon Quest (Fortune Street)

Geno vs Imajin - Maybe the connection is collaboration, because of Square and Fuji TV. Maybe

Petey Piranha vs Chain Chomp - Petey Piranha is a character of it's own, and Chain Chomp is more of a species. So maybe just Piranha Plant vs Chain Chomp would do just fine
