Orne

Ornes (オーン, Ōn) are members of the Underworld Army in the Kid Icarus franchise. They appear as a giant horned skull with a mass of smaller skulls. They appear as an enemy in Super Smash Bros. 4's Smash Run. Like in Uprising, they immediately annihilate those they touch.

Origins
Ornes were introduced in Kid Icarus: Uprising as one of the Underworld troops. Although they simply move about a pattern and rarely seek Pit out, they would instantly cause death on contact with him, and are the one non-boss enemy that can do so. They are invulnerable to all forms of weaponry except for the Arrows of Light.
