Arm attacks are boosted by Arm Attack stickers in Super Smash Bros. Brawl's The Subspace Emissary, the Strong Punch power in Super Smash Bros. for Nintendo 3DS's Smash Run, and the Spirit skill or trait Fist Attack ↑ as well as certain Spirit Battle conditions in Super Smash Bros. Ultimate.
The Arm type is subdivided into two subtypes: Hand and Elbow. In Super Smash Bros. Ultimate, the supertype physical (which is boosted by the Physical Attack ↑ Spirit skill) encompasses the types Arm, Leg, and Bite.
