Receptionist: A strong one-on-one would be with Metal Mario, but he's currently facing a woman named Mai, so you'll have to wait for their battle to finish. ^_^
Spazzy:
This RP takes place in the Subspace Emissary world. (Y'know, with all the geographic locations, the Arena, etc.)
Most characters start out in the Arena, though some can start in other locations, like the forest or swamp/jungle or whatever. You didn't note specific locations, so I'll assume all your pplz are at the Arena.
