A dash attack (ダッシュ攻撃) is an attack performed by pressing the attack button while dashing. Most dash attacks come out quickly but have noticeable ending lag, making them very easy for wary opponents to punish (particularly using a shield grab). Prior to Super Smash Bros. Ultimate, many dash attacks could be used for cross-ups due to a large amount of momentum inherited from the prior dash, though there are still multiple dash attacks with this property in Ultimate.
If the grab button or either of the shield buttons are pressed repeatedly right after attempting a dash attack, the attack will be canceled and turned into a boost grab. Similarly, in Brawl, many dash attacks can be interrupted by performing an up smash in a technique labeled the dash attack canceled up smash (DACUS) to provide a large boost of momentum. Certain dash attacks are fast enough to hit before the up smash comes out, allowing for a Gatling Combo.
