Hildon

Hildon is zombie who resembles a stitched-up vampire whom Nami, Chopper, and Usopp met in a tree while hiding from the Cerberus.

Appearance
Hildon has a bat like body with wings capable of flight, and legs capable of suspending him upside down. He has sharp fangs, claws and his eyes, if not sunken, that seem to have strange tattoos encircling them. Above his right eye is the number 21.

History
After the three Straw Hats escaped from the Cerberus, Hildon offered to take Nami, Usopp and Chopper on a carriage ride to the mansion where Dr. 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 Moria of this as well as when Ryuuma is beaten by Zoro.

As of chapter 481 his shadow was absorbed by Gecko Moria's Shadow Asgard technique to increase his power, leaving him a hollow shell once again.

Trivia

 * Hildon bears a striking resemblance to Eyeshield 21's (an American football sports manga also published in weekly shonen jump) Yoichi Hiruma. Hildon also has the number 21 over one of his eyes and when in flight is similar in appearance to the cartoonish bat mascot of the Deimon Devilbats, Hiruma's team.
