Instead of specific characters, there are series that I seriously think got shafted in the trophy department:
-The Mother series (hooray, the only new Wii U trophy is a from the Ultimate Chimera form NPC)
-Fire Emblem (lol at all the trophies being shat out from Brawl, nice going there guys)
-Post-Air Ride Kirby trophies (imho, it has to do with sakurai bias since air ride was the last game he worked on, which also explains why we haven't gotten a Kirby stage from any game past KSS, a game which came out 20 years ago)
-Wario series (it's improved from Brawls pathetic selection, but it's not great either....i guess he got it better than yoshi though?)
