My list of MU experience for Wii Fit Trainer
Extremely bad MU's for Wii Fit:
--Mario- Reflect, combos us badly, out ranges us and is a small target and he can out camp us. He's literally made to counter all Wii Fit options.
--Villager - Disjointed hit boxes and fair/Blair/nair prevent our usual movements. Can camp us and absorb our projectiles and use them against us. Can gimp us pretty well.
--Olimar/Alph- Side B Pikmin throw. This move alone shuts us down and there's not too mucH we can do against it. We can't really rush down, because we are pretty floaty and Olimar avoids attacks due to his small size. He out ranges and just has to run away from us. Olimar times Wii Fit out pretty easily.
--Diddy Kong- This guy literally says "FU" to almost every option. All his aerials out beat and outrange us. Banana pressure is tough and he is also small and speedy.
--Mr. Game and Watch- Small target who can absorb our stuff. Spaced back air and up air is hella annoying against Wii Fit and he has combos out of grabs.
--Pikachu- Super small, speedy and mobile. Combos us and can camp us with thunder jolt. Quick attack shenanigans make it tough to hit and gimp.
--Sonic- You need a semi charged to full charged Sun ball to hit him out of spin dash. His damage output is silly and he wrecks Wii Fit when he closes in and there isn't too much we can do about it.
--Sheik- Fair literally shuts us down. That's all she needs to get the lead against us. Her needles out beat so much of our stuff. Super speedy and a combo freak.
--Luigi- Fire balls and grabs is all he needs. Fighting Wii fit is pretty easy for Luigi since Wii Fit can't really approach him safely to begin with.
--Duck Hunt- Hide behind projectiles is all he needs to do. Wii fit is trying to close in? Duck hunt can just retreat and repeat the cycle. His gunmen and crap protect Duck Hunt from our projectiles. He out ranges and badly camps us out.
Great players with these characters will be an extreme nuciance. Prepare for an extremely stressful battle that will require great reflexes and massive thought. One error can easily turn the tide against you instantly against these characters. The MU isn't impossible, but it kinda feels like it. Do your best and try to be perfect no matter what.
Bad Match ups for Wii Fit:
Rosalina
Captain Falcon
Ness
Yoshi
Fox
Kirby
MegaMan
Toon Link
Mii Gunner(if customs for Mii's are legal)
These characters all counter Wii Fit very well. Wii Fit either gets out ranged, rush downed or zoned out badly by all these characters. Some of them are tough to hit for him\her. The battle is doable, but pretty tough.
Somewhat bad match ups for Wii Fit:
--Peach(combo us for days, Rush us down and ledge guard us pretty bad. She also out ranges and out prioritizes as well)
--Falco(Reflector shuts down our projectiles pretty bad and he outrages and out prioritizes us)
--Meta Knight(Can rush you down me get early kills on you, pretty tough to gimp as well)
--Dr. Mario(Easier to gimp, but still very annoying like Mario)
--Marth(Tippers and outrages you when spaced correctly. Can rush you down as well)
--Pac Man(I don't understand why people say Wii Fit has the MU advantage on this one lol. A good pac man is hell for Wii fit. A total camp fest)
--Greninja(Small stance makes him tough to hit and he outrages us)
--Jigglypuff(She's very light, but she does outrange us with aerials and she can gimp us easily when used right)
--Zero Suit Samus(She out ranges us, can close in well and do silly kills with combos)
--Mii Brawler(tiny custom brawler)(He's small and can rush you down easily. Can score early kills with helicopter kick)
--Lucas(Small, out ranges us, can combo us and can absorb our Sun. Pretty tough to gimp)
--Ryu(The stupid combos he can execute into kill moves. Pretty tough to gimp and has annoying shield stun and breaking capabilities)
Match ups Wii Fit has the advantage against:
--Robin(Literally a free win for me. No reason to lose this MU. Combo fodder, slow and easy to gimp)
--Mii Brawler(Default 1111)(Gimp bait and you can just camp him out)
--Bowser Jr(Literally all you have to do is play campy and throw out header and Sun balls when you see him approach or use Koopa drift. Extremely easy to gimp. Extreme combo fodder)
--Zelda(She is forced to approach you. She has a reflector, but she's combo fodder as well and you out camp her pretty bad. Her kill moves are pretty easy to see coming)
--Charizard(Ultra combo fodder and pretty easy to gimp as well. Just avoid grab and side b and you are pretty much set in this MU)
Anyone else not listed has like around a 50|50 MU vs Wii Fit Trainer.
