Toad (move)

The Toad move in the Super Smash Bros. series will cause Princess Peach to release Toad, a character and species from the Super Mario series, and basically use him as a shield, though unlike a regular shield he'll only stay out for a second, though will also deliver health to Princess Peach if he manages to block a progjectile such as a Missile.

It should also be noted that this is Kirby's copy ability if he Inhales Peach.
