Ground attack is an attack made while the character is standing on the ground, as opposed to air attacks, which are performed while the character is airborne. Both special moves and normal attacks can be ground attacks. Some attacks behave differently when performed as ground attacks. An example of this is Link's up special move, which can be charged (starting in Brawl) if performed on the ground. A few special attacks can only be performed on the ground, specifically Donkey Kong's Hand Slap (prior to Super Smash Bros. for Nintendo 3DS/Wii U) and Peach's Vegetable; in a similar way, Olimar's Pikmin Pluck can be used in the air, but only has an effect when grounded.
