Piranha Plant - Oddball picks can be fun, can't be mad at this one.
Joker - I would've rather they simply done Jack Frost or SMT4's Flynn, but I get why they went with the main character of their most popular game ever. Hero - Cool Banjo & Kazooie - Meh Terry - Extra meh Byleth - lol, but I don't really mind it. Should've been Claude.
Min Min - Don't care about ARMS, but this probably means there will be a sequel. Steve/Alex - Meh Sephiroth - I hate this. Pyra/Mythra - Hooray! I would've preferred Rex in a Pokemon Trainer style, but this is fine. Kazuya - Extra meh Sora - Great
