Fury Shadow

Fury Shadows are enemies that appear 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. They seem to possess many of Mario's abilities, such as the Wall Jump.

Fury Shadows appear in Fur Step Island, Scamper Shores, Crisp Climb Castle, and Risky Whisker Island. Each of these islands has a corresponding mission with "Fury Shadow" in its name. When one of these missions becomes available, a spiky black ball of goop similar to what covers Fury Bowser appears near the entrance of the island. The Fury Shadow will burst out of this ball as its red eyes flare, and it will then begin to run away from Mario.

Similarly to Shadow Mario encounters from Super Mario Sunshine, the Fury Shadow follows a set path around the island it is found on. The player must chase after it to land a hit, either by jumping on it with Mario or using Bowser Jr.'s Magic Paintbrush. If not pursued, the Fury Shadow will taunt the player as it waits in place. Landing a hit on it will cause the yellowish-orange health bar above its head to deplete. It will then enter its ball form to quickly retreat away from Mario before turning back into its humanoid form as the process repeats.

After being hit three times, the Fury Shadow will disintegrate, and Mario is rewarded with a Cat Shine.
