Donkey Kong Country: Tropical Freeze is a game in dire need of proper representation in Smash, and if K. Rool is the only newcomer, the game would appear to be entirely ignored (since I doubt we're getting any DKCTF stage, item, or AT)... Unless, Dixie makes it in (or Cranky of Funky, I guess, but most likely Dixie). Seeing its success on Switch makes me hopeful, but also, I doubt the game's port was on the radar when Sakurai started the roster. But dangit, Tropical Freeze is the best received DKC game ever (well, some fans argue DKC2, but from a design perspective, DKCTF seems to be the best of the bunch), and it'd be a complete shame if it's not given the attention it deserves.
I just wish Smash Ultimate can give us both K. Rool and Dixie Kong, because both characters can represent very different parts of the DK franchise, and are both completely deserving. If Kirby could get two unique newcomers in Brawl, this game can too (so could the last game, but... ugh).
