Priority is a property of hitboxes in the Super Smash Bros. series that defines their behaviour when interacting with other hitboxes. The mechanics of normal priority state that two attacks will cancel each other out if they deal similar damage (within 8%), whereas otherwise one attack will overpower and go through the other - aerial attacks, however, are not completely interrupted. Certain hitboxes also have transcendent priority, which prevents them from colliding with other attacks, for example, the hitboxes of Fox's lasers cannot be canceled by attacks. The term "priority" is often - technically incorrectly - used as a measure of an attack's hitbox location and timing. (more...)]
