Honestly there is A LOT of JRPG characters in the roster right now. Ness, Pikachu, Jigglypuff, Marth, Roy, Pichu, Mewtwo, Ike, Lucas, Squirtel, Ivysaur, Charizard, Robin, Lucina, Lucario, Greninja, Corrin, Cloud, Chrom, Joker, The Hero, Sephiroth, Incineroar, Shulk, Pyra, Mythra.
That's 26, which is over 1/4 of the roster. I get JRPGs are popular, especially in Japan, but I feel as if it's a bit much considering how many see Smash as "Gamings ultimate crossover" when an entire fraction of the roster belongs to one genre as some of the biggest have no reps in general. Run n' Guns, Survival Horror, FPS, MOBA, simulator, Shoot em' Ups, Rhythm, Text based Adventures, ect.
I don't hate JRPGs, sword fighters or any of the inclusions. I just kind of wish Smash representation was a little more balanced on genre and origin.
