Honestly I think most the Gen 1 Pokemon would work fine as Smashers;
looks set to prove his worth in Pokken for example alongside
.
or
could easily make for that fighting game staple who steals other people's moves to fight.
would work fine were it not for
filling his niche as telekinetic glass cannon.
as you said would be a great speedy fighter.
obviously have fighting movesets based off real life fight styles. Mac fills Hitmonchan's niche a bit though.
would both work fine as bulky projectile characters with Venusaur not even needing much of a change from
's moveset.
Essentially Dillon; claws and spin attacks.
Could also double as a cross between a Sonic style spinner and a heavy projectile character.
; come on this guy screams potential.
tl;dr: I think you're selling Gen 1 short in terms of abilities. It's just there's a lot of crossover.
