Hildon

Hildon is stitched-up vampire whom Nami, Chopper, and Usopp met in a tree while hiding from the Cerberus. 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. He 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 riden by a hunchback holding a lantern, Hildon takes the three through the forest of Thriller Barque and leaves them in a graveyard. He then flies off towards the mansion.
