Giants

Giants or Gigantum Mortis, are a species of gigantic undead creatures that live in the United Kingdom (England).

History
Giants long ago populated the British lands until they were forced and killed by humans who organized themselves into "Wild Hunt" members to partake in Giant slaying in order to keep human villages safe from these monsters. The Osiris Club consisted a group of regularly giant hunters, and on one occasion in which Professor Broom partook in their mission. After a decade the Osiris Club invites Hellboy to partake in one of their hunts while they also reveal him his origins and past. After the hunters betray him, three giants arrive and slaughter all the members expect for Hellboy, who was unconscious because of his wounds. After regaining consciousness, Hellboy then battles the giants by easily killing all three of them before eventually passing out.

Characteristics
Giants are huge humanoid beings that are mostly covered in mammal fur and several manmade junk parts that they could find. They have several horns on their heads and some have small tusks inside their mouths. After they are killed, the giants come back from the dead as undead monsters. Their favourite food is spinal fluid found in human bodies and they never leave bodies of uneaten humans behind.
