Fury Shadow

Fury Shadows are a new type of enemy that make their debut exclusively in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury. They are black, goop-covered creatures with luminescent red eyes, resembling Luigi. A yellowish-orange health-bar rests above their heads. They seem to possess many of Mario's abilities, such as the Wall Jump. They taunt the player if they are not pursued.

It is not currently known what causes Fury Shadows to appear, but when they do, they show up in a spiky black ball of goop (similar to what Fury Bowser is covered in), which they quickly explode out of upon arrival. They also have the ability to revert to this form whenever they are hit, allowing them to move faster. Mario must then chase after them and land three hits in order to make them disintegrate, rewarding him with a Cat Shine.
