Mario being hit by Ivysaur's Bullet Seed, a grass attack, in Brawl
Grass is an attack effect in Super Smash Bros. Brawl. Grass attacks have the same visual appearance as slash attacks, generating a crescent-shaped visual effect.
In Brawl, due to type effectiveness, grass attacks deal 110% knockback to Squirtle and 90% knockback to Charizard. The only playable characters that can use grass attacks are Ivysaur and Kirby (by copying Ivysaur).
Ivysaur is the only character that has grass attacks, other than Kirby copying Ivysaur's Bullet Seed.
The Subspace Emissary
In The Subspace Emissary, almost all enemies have the same resistance to both slash and grass attacks; Primids are the only exception, taking 1.3× damage from slash attacks but 1.0× from grass attacks.
