Dullahan Cube

Dullahan Cube (地陰星 デュラハンのキューブ, Chiinsei Dyurahan no Kyūbu) is a Specter who was sent among the 17 Specters infiltrating Athena's Sanctuary, to keep tabs on the revived Gold Saints. Takes his power from the Terrestrial Shadowy Star

Plot (TLC)
Cube was first seen among the group of Specters that attacked Alone and Tenma's village in Italy and, along with Bat Wimber, he is one of the assassins that Pandora sends to the Sanctuary in order to kill Pegasus Tenma. He is almost done with his task, but is stopped by Taurus Rasgado while delivering the finishing blow. Nevertheless, he is the one who kills the Taurus Saint, albeit he is slain soon after by the Titan's Nova.

Plot (Hades Arc)
During the invasion of the Sanctuary, the revived Gold Saints feigned their defeat in an attack from Virgo Shaka, which destroyed the Cancer Temple. In the confusion, Saga killed Cube and took his Surplice as a disguise, as it covered most of the Gemini Saint's body. Cube's dead body was later found by the four Bronze Saints, noticing he had exploded from inside, suspecting he was victim of a familiar technique, the "Galaxian Explosion".

In Leo Temple, this wingless-headless-centaur feature of Dullahan Surplice hurted Aiolia emotionally because his brother Aiolos wore the winged-unbeheaded-centaur (Sagittarius) Cloth. Aiolia declared he would kill all enemies who try to trespass his Temple, but was distracted by the approaching of the friendly Cosmos of Saga, Camus and Shura. Giving a chance Worm Raimi to bind Aiolia. When the three revived Gold Saints reached the Virgo Temple, Shaka used his power to destroy the Surplices, revealing the true identity of the impostors.

Surplice, Star & Name

 * Dullahan Surplice.jpgDullahan Surplice

The Irish dullahan is a type of unseelie fairie. It is headless, usually seen riding a black horse and carrying his head under one arm. The head's eyes are massive and constantly dart about like flies, while the mouth is constantly in a hideous grin that touches both sides of the head. The flesh of the head is said to have the color and consistency of moldy cheese. The dullahan's whip is actually a human corpse's spine, and the wagons they sometimes use are made of similarly funereal objects (e.g. candles in skulls to light the way, the spokes of the wheels made from thigh bones, the wagon's covering made from a worm-chewn pall). When the dullahan stops riding, it is where a person is due to die. The dullahan calls out their name, at which point they immediately perish.

There is no way to bar the road against a dullahan―all locks and gates open on their own when it approaches. Also, they do not appreciate being watched while on their errands, throwing a basin of blood on those who dare to do so (often a mark that they are among the next to die), or even lashing out the watchers' eyes with their whips. Nonetheless, they are frightened of gold, and even a single gold pin can drive a dullahan away.
 * Terrestrial Shadow Star

Cube's star originates from the character Gu Dasao, from the Water Margin story.
