Morton Koopa was made paralyzer after I came to the realization that in almost all of his appearances he stuns Mario / others by slamming into the ground.
I think Wario can be any of the following: Zombie - there is a zombie Wario form Prophet - lol play on words for profit Politician - he plays both sides of the field, also he's the head of a corporation
The next two Smash 64 cameos - Caroler and Celebrity(?)
I'd make Pikachu lightkeeper but I want to keep Watt, so the only other role that works is Celebrity. To be fair, Pikachu is probably more famous than Mario at this point.
Progress updated. Made Rosalina granny since she's really old and tells stories - Lakitu is now Driver since he's the closest thing Mario has to a vehicle driver (aside from mario kart hurrrrr)
I drew Luma for Mimic/Amnesiac, since they can transform, but then I thought about it. He doesn't transform into other characters, he transforms into... space stuff.
I was thinking Vivian for Ghoul, but is she really a ghoul? Dry Bones fits a few roles. BP - he can take more than one hit. Survivor - no matter how many times you stomp him, he survives. Zombie - self explanitory.
I'm going back to TheWorst's suggestions from a while ago. I'm going to make Luma's amnesiac or mimic, and Kirby will be the other.
Tubba Blubba's heart should be strong man. He was a tough boss as a kid.
Also, for some of the unassigned ones in the OP:
Geno for Deputy/Sheriff/Vig [The bullet finger move] Toadswoth for Granny [Mostly because old] Grodus for Enforcer [Sounds intimidating for him] Koopa for BP Wario for Consierge? Unless you want him 3rd party.
