Hildon

Hildon was a zombie who resembled a stitched-up vampire. He appears to act as a messenger in-between the members of Thriller Bark's Mysterious Four, reporting to them noteworthy events that are happening throughout the island ship before it fell.

Appearance
Hildon had a bat like body with a black cape that is also his wings that enable him flight, and legs capable of suspending him upside down. He had sharp fangs and claws, a long stitched nose, pointed ears, and his eyes, if not sunken, seem to have strange tattoos encircling them. Above his right eye is the number 21.

When he first appeared, he carried with him, over his back, a very large long-necked bottle of what appeared to be liquor. He somewhat resembles a vampire.

History
After the three Straw Hats escaped from the Cerberus, Hildon offered to take Nami, Chopper and Usopp on a carriage ride to the mansion where Hogback lives.

In the carriage drawn by a Centaur and by what looks like a hound ridden by a hunchback holding a lantern, Hildon takes the three through the forest of Thriller Bark and leaves them in a graveyard. He then flies off towards the mansion.

Later, after the Straw Hats begin their counter attack on Thriller Bark, he warns Moriah of this as well as when Ryuma is beaten by Zoro.

Moriah, after being beaten by Luffy, used his Shadow Asgard technique to increase his power by absorbing all one thousand shadows in Thriller Bark, thus leaving Hildon a hollow shell once again.
