For each company, add a character

[Perkilator]

Simply put, just add a character from each company that has one. You can do multiple ones for Nintendo (as many as you want), but only ONE per third party company (including ONE freebie for a company who's not represented yet). I'll start:

Nintendo
-Pauline (Mario)
-Shy Guy (Yoshi)
-Bandana Dee (Kirby)
-Slippy (Star Fox)
-Scorbunny (Pokémon)
-Porky (Earthbound)
-Caeda (Fire Emblem)
-Cpt. Syrup (Wario)
-Alph (Pikmin; 40 Echo)
-Tom Nook (Animal Crossing)
-King Hippo (Punch-Out!!)
-Riki (Xenoblade)
-Ninjara (ARMS; 76 Echo)
-Balloon Fighter (Retro Nintendo)
-DeMille (Tomato Adventure; misc. Nintendo)

Now, for the third parties:

Konami: Frogger
SEGA: Sakura Shinguji (Sakura Wars)
