I don't like Wii Fit Trainer.
Piranha Plant works way better as a joke character in a crossover videogame fighter, since you know, he's actually a character just like all the others, with a moveset filled to the brim with references to his original appearances and everything. It's just that instead of a superstar or a menacing villain, it's a random Mario enemy, and even one of the most absurd ones. I mean, a potted plant?? And then you see it beat up Ridley, Ganondorf and Mario himself and, yep, that's a joke character. Mr. Game & Watch and R.O.B. more or less fall into the same cateogry.
The Wii Fit Trainer meanwhile just does yoga poses. That's it. That's one joke repeated 20 times (or how many moves a Smash moveset has, too lazy to count now).
She's also so generic and so detached from everything that she could very well may not have come from any game, but just be a generic real-world yoga instructor somehow translated into Smash. You could conjure up a moveset of that kind even for a football player, or for a swimmer, or even for a guitarist or for a business manager (ahahah, see? he throws paperwork and money at you!) or basically anything else.
Not a fan at all. Back during Smash 4 I thought she was a wasted spot. now I've kinda eased up on her but I still think that almost anyone else would have been a better choice.
