Ornes (オーン, Orne) are members of the Underworld Army in the Kid Icarus franchise. They appear as a giant horned skull with a mass of smaller skulls.
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 only non-boss enemy that can do so. They are invulnerable to all forms of weaponry except for the Arrows of Light. Pit even voices his dismay when Ornes appear before the Chaos Kin's battle.
Ornes rarely appear as enemies. Like in Uprising, they slowly pursue players and instantly kill them on contact. Ornes do not deal any damage, but their unique Obliviate effect instantly destroys anything that touches them unless invincible or intangible. As an added auditory cue, the currently-playing music will be replaced by creepy 8-bit music from Uprising that would play whenever Ornes got close to Pit.
An Orne is immune to all damage and knockback: therefore, the only defense from this enemy is to either avoid it entirely, or use rolls, air dodges (spot dodges aren't recommended) to become intangible and safely pass through it, or using Powers such as Warp and Brief Invincibility. Orne moves faster if the player's back is turned towards it. The Super Star can allow players to touch Orne without evading or being KOed, but they still cannot KO it, or even make it flinch.
