Grass (effect)

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.

Due to type effectiveness, grass attacks deal 110% knockback to and 90% knockback to. Aside from being boosted by Grass Attack stickers, this is its only gameplay effect.

is the only character that has grass attacks, other than copying Ivysaur's Bullet Seed.

Grass is the only major effect to not return in future games. No known attacks in Super Smash Bros. 4 or Super Smash Bros. Ultimate use it; despite Ivysaur being present in the latter, its attacks are generally Normal. It is unknown whether the effect is merely unused, or removed outright.

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.

Trivia

 * Although some attacks have a plant-like aesthetic to them, they are considered slash attacks instead. These include Venusaur and Snivy's Razor Leaf and Mega Man's Leaf Shield. This is due to the grass effect being exclusive to Brawl.
 * Additionally, Chikorita is a Poké Ball summon in Brawl, but its Razor Leaf attack does not have the Grass effect.
