Fox (SSBB)/Back aerial
Fox performs a fast kick behind himself. Deals 15% damage. It is rather powerful, being capable of KO'ing reliably under 150%, and is useful for edgeguarding. If the move is sweetspotted, it hits opponents on a semi-spike trajectory, and is one of the strongest semi-spikes in Brawl. However, its short range and short-lasting hitbox hinders its effectiveness, especially for spacing. It also has high ending lag, making it somewhat risky to use offstage. Despite its high ending lag, however, it has little landing lag (similar to Lucario's neutral aerial), making it a safe move to use in a short hop fast fall or RAR. If sourspotted, it instead hits opponents at the Sakurai angle.
