Cape

Cape is Mario's side special move in SSBGA. Mario pulls out his cape from SMW and whips it across to turn anybody in the opposite direction as well as 10% of damage obtained by the enemy coming into contact. This move propels Mario forwards. This move in addition reflects projectiles to guide them directly back on the foe who launched, whether its an item, or a personal projectile of their moveset. However, this move cannot repel Final Smashes that are consisting of launched projectiles, as it interrupts the Cape animation and Mario will be attacked. A new technique, known as the Cape Glide, is implemented in the game.

Origin
This move is originated from Super Mario World. When Mario or Luigi acquire a Cape Feather, they will become Cape Mario/Luigi. This form can allow them to fly as soon as they dashed briefly for a short period and then jump. They ascend to the sky. If the player presses the d-pad downwards, the plumber will plunge downward and vice versa to become mobile in midair. When the player press the corresponding button of jumping while in midair, Mario/Luigi will slowly descend to the ground. If they mount Yoshi, while performing the action of gliding, they fly vertically until they come into contact by an enemy or affected by an obstacle. Though, unlike the regular procedure, The player is unable to descend downward to gain speed.
