Zuree

Zuree is an enemy that appears in both Kid Icarus and Kid Icarus: Uprising. In the latter game, they can shift into a blue flame that is not affected by attacks, but it will shift back to its true form to attack which can also be attacked at this state.

In Super Smash Bros. for Nintendo 3DS, Zurees appear as enemies in Smash Run. Like in Kid Icarus: Uprising, they are generally invisible, distinguished only by a blue flame. Eventually, they attempt to ambush the player, revealing themselves, making a characteristic noise, and swiping with their claws, which deals high, downward knockback. Their attack patter is similar to the Flage, another enemy that has originated in Kid Icarus: Uprising.

One variety on the Survive! Challenge on Hard difficulty, which can be triggered if players enter a Challenge Door, has a multitude of Zurees attacking the player.
