I just realized; certain characters’ playstyle are the way they are to (possibly) fill a playstyle archetype.
Mario: Mr. Basic playstyle
Donkey Kong: Gorilla playstyle
Samus: Space Marine playstyle (kinda?)
Kirby: Mimic playstyle
Ice Climbers: 2-in-1 Fighter playstyle
Sheik and Greninja: Ninja playstyle (in case you couldn’t tell from the latter’s name)
Zelda: Mystic Girl playstyle
Marth, Roy, Ike, Lucina and Chrom: Bare Swordsman playstyle
Diddy Kong: Small Animal playstyle
Olimar: Commander playstyle
Mega Man and the Belmonts: NES Platformer playstyle
Little Mac: Boxer playstyle
Miis: ANY playstyle the player chooses
Robin: Magical Knight playstyle
Bowser Jr. and the Koopalings: Mech Suit playstyle
Ryu, Ken and Terry: Traditional Fighting Game playstyle
Incineroar: Wrester playstyle
Joker: Master Thief playstyle
Hero: Turn-Based RPG playstyle
Byleth: Master of Arms playstyle
Min-Min: Master of TWO Arms playstyle
I’m not necessarily defending or knocking these playstyles. Just wanted to get analytical about them.
