here's my script for it (if you're interested)

(all 9 marios land on final destination)

N64 mario: here we go!

(N64 mario goes for wii mario, who propels away with the propellor hat, as SNES mario flies at switch mario)

(NES mario jumps on paper mario and DS mario, but N64 mario kicks NES mario from behind, knocking him off the platform)

(galaxy mario jumps and hits SNES mario, who flies around with the cape feather and spin attacks, knocking galaxy mario away)

(N64 mario ground pounds towards NES mario and squishes him instantly)

(DS mario consumes a mega mushroom and becomes giant, but SNES mario flies just out of reach, and waits for the mushroom to wear off, before spin attacking DS mario off the platform)

DS mario: oh no!

(paper mario jumps up, and summons the fan, blowing final destination across the cosmos)

(wii mario wobbles around dizzy, when gamecube mario uses FLUDD to blast him away and jumps on him to knock him off the platform)

wii mario: ahhhh!

(gamecube mario is celebrating, when paper mario whacks him with a shiny hammer, and sends him flying into a nearby black hole)

gamecube mario: waaaaaaaa!

(paper mario is attacked from behind by galaxy mario, and knocked back, while SNES mario and switch mario fight each other)

(N64 mario tries to attack paper, but paper mario pulls out shiny boots, and with one giant stomp, squishes N64 mario...)

(or so he thought, as N64 mario puts on the metal cap and punches paper mario into the sky before punching him again, knocking him out cold)

(switch mario uses cappy to take control of SNES mario, and dives into the pit, killing both of them)

(N64 mario, paper mario and galaxy mario stand facing each other)

(N64 mario BLGs into galaxy mario, and puts on the winged cap and picks him up)

(he unleashes a flurry of punches, but realizes galaxy mario has used the spring mushroom, and he springs into N64 mario, knocking him back)

(N64 mario puts on the winged and metal cap at the same time, and he punches galaxy mario so hard, he flies into a nearby planet, blowing it up)

(N64 mario grabs galaxy mario by the foot)

N64 mario: so long, gay plumber! (sorry i just had to)

(galaxy mario is launched into the sun and dies instantly)

(N64 mario celebrates, but looks back too late to see paper mario spinning his hammer)

(paper mario grabs a shiny hurlhammer and puts on legendary iron boots, and with a stomp and hammer, vaporizes N64 mario instantly)

(with that, paper mario finally speaks:)

paper mario: wahoo! i'm the winner!

K.O!

out of all these marios, who would win?
