The Wii Fit Trainer was an odd and yet perfect addition to the Super Smash Bros. roster in its latest iteration on the Wii U. Not because she so perfectly fits as a fighter, but actually the opposite. Super Smash Bros. has always been just as much about introducing fun characters that deserve that may not fit the fighter theme as it is about which character is strongest. Megaman is about finding finding out who is strongest, Wii Fit Trainer and Villager are about keeping Smash Bros. unique and fun.
There's no better example of this, I think, than these recently released screenshots showcasing the Wii Fit Trainer's powers and abilities. Instead of transforming her in a punching and kicking shadow of the Wii Fit Trainer, Namco Bandai does what Smash Bros. does best -- they use aspects that the character is known for and turn them into attacks. Stretches, sports, exercises, they're all perfectly strong enough to stand up against the rest of the crew without giving her Chun Li thighs or something.
Retaining that iconic feel for every character is the key to the Super Smash Bros. experience. Megaman wouldn't be Megaman if he couldn't use multiple abilities, if he couldn't slide. Captain Falcon wouldn't be himself without his paunch. When I see the Wii Fit Trainer's ultimate, which flashes the shapes the Trainer asks to player to conform to while playing her game, I see every reason I love Smash Bros. It's not just the fighting, its pulling characters out of their game with as little changes as possible and seeing who is strongest.
Super Smash Bros. for Wii U and 3DS is scheduled for release in 2014 (gah). The wait will be painful, but it will be a wonderful torture as each roster spot is revealed to us one by one. Good to have you back in excellent form, Smash.
