Cape Feather

The Cape Feather is an Item in Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2. Gaining it turns Mario into 'Cape Mario' which makes him fashion a superhero-esque yellow cape and grants him flying capabilities. It is exclusive to the  Game Style (though it does have equivalents in other Game Styles).

When present, it will float down while swaying from left to right, like that of a feather.

Origins
The Cape Feather made its debut in 1990's Super Mario World for the SNES. However, it should be noted that the tiering system introduced in Super Mario Bros. 3 for Power-Ups that the Super Mario Maker series relies was not present in  Super Mario World. So it could be considered mechanically different from the original game.



Flight
Becoming 'Cape Mario' via the Cape Feather gives Mario the ability to fly. This can be achieved by running and then pressing B. Being hit while flying also only halts your flight rather than make you revert to Super Mario.

Spinning
You can spin as Cape Mario when you're not flying and your cape will hurt enemies near you. It can also hit nearby blocks.

Fast Dive
If you hold down Y and a directional button, you can make a fast dive. You can land and hurt an enemy this way, or if you fast dive on the ground, you can make it shake and destroy nearby enemies.

Slow Landing
With the use a directional button and B, you can slow Mario's descent and make a jump easier to land.

Night Behavior
Exclusive to Super Mario Maker 2, the Cape Feather will sway back and forth with greater distance than normal when Night Mode is enabled for the Overworld Theme.



Trivia

 * According to 'datamined' sprites from the original Super Mario World and Super Mario Maker, there are some differences between both sprites.
 * Some sprites for Super Mario/Cape Mario jumping at full speed are missing one of Mario's feet. This has since been fixed in Super Mario Maker 2.
 * The colors aren't 100% accurate to the original.
