Back Slash grants a small jump while initiating, making it useful for jumping over small projectiles. It does grant some horizontal movement, but is risky for recovery as Shulk can grab the ledge while using Back Slash, although it requires a long falling distance for this to come into effect. Because of this, as well as the move's inability to be cancelled, Shulk will inevitably self-destruct if Back Slash is used off-stage.
The move does around 7% to 9% if used against enemies that are facing Shulk, but can deal between 11% to 16% when striking behind them. The damage on a back-hitting Back Slash is increased to 22% with high shield damage while in Buster mode, and is a reliable KO option in Smash mode, KOing at around 90% at the back (middle of stage) and 118% at the front (near the edge).
Back Slash is a useful move for avoiding low projectiles, as well as a good punishing move. As the name implies, it is an effective sneak attack against unaware opponents. However, Back Slash also has high ending lag, making it very unsafe if shielded and leading Shulk to be punished.

Back Slash was one of Shulk's Physical Arts in Xenoblade Chronicles; he performed a simple strike which did extra damage when used from behind.
- If Shulk connects with Back Slash from behind, the opponent will be launched while continuing to be facing away from Shulk, making the move unique as most characters turn around when hit.
