If I'm not mistaken, Remix is a lot of independent devs making their own characters. That's why there's such a quality gap between Toad and Simon.
Oh yeah, some characters look really good, like Toad or Bomberman. But then you have others like Masked Man and Toon Zelda who stick out like a sore thumb.
And then there's Palutena, who has Autoreticle, despite it being neither homing nor actually showing a reticle. I feel like they should've taken more liberties with using her SSB4 custom moves instead of trying to copy Ultimate's moveset, considering that move's homing ability is what made it useful.
But then again, I might be biased, considering she was my main in SSB4, but I did kind of drop her in Ultimate for the most part. Apparently she's pretty good this time around though.
