So... yeah. I know I didn't expect her. Anyway, her moveset consists of various yoga poses and stuff inspired by exercises from the Wii Fit games, and her Final Smash, "Wii Fit," has her summon silhouettes of yoga poses to attack the enemy. Overall, while her introduction is very tongue-in-cheek, I have to say the Trainer is a welcome addition to this game just from her trailer.
So yeah, as new stages and characters for Smash Bros. 4 are announced, I'll be here, updating on the new stuff that is known. I'll do another post soon detailing the Animal Crossing Villager, Megaman, and what we know of the new stages. If you want more immediate updates, make sure to visit the Super Smash Bros. website, or, if you have a Wii U, the Smash Bros. Series Miiverse Community, where Sakurai will be updating about 5 times a week.
HBM, signing out.
