Cape

The Cape is a magical item first appearing in Super Mario World as well as its Game Boy Advance remake. Mario and Luigi gain it upon touching a Feather (an item usually found in ? Blocks), and it gives them the ability to fly, among other things.

In Super Mario World 2: Yoshi's Island and its Game Boy Advance remake, Baby Mario could get a cape and become invincible by touching a star; Yoshi, upon doing this, would turn into a Yoshi Egg and follow with the rest of the eggs.

The cape also makes an appearance in Super Mario Advance 4: Super Mario Bros 3. It could only be obtained by using an e-Reader card to scan the feather in to the player's item inventory. The feather and in turn the cape was also found in the Japan-only World-e level Henshin Mario de Tsukisusume!!. The cape has the same effects as it does in Super Mario World.

Mario later uses it as an attack in Super Smash Bros. Melee and Super Smash Bros. Brawl. It is his Side + B move. While this attack is not particularly powerful, it is useful in that it can reverse the direction of certain projectile attacks. It can also make the foe spin around, and face the other direction.
