Boost Kick is Zero Suit Samus' Up Special Move in Super Smash Bros. for Nintendo 3DS and Wii U, replacing the Plasma Wire from Super Smash Bros. Brawl. Zero Suit Samus uses her jet boots and does a kick that propel herself upward, finishing with an outwards kick. Opponents hit by the start of the move will be carried upwards with her and then launched by the second kick.
