They are Secondary Bone Suckers, transformed from Goblins.
Next are the Bone Suckers that somewhat resemble Bear Goblins.
The final highlight is the Advanced Bone Suckers, with bodies exceeding four or five meters, clearly possessing Giant blood.
The original Bone Suckers were transformed by a mysterious ritual created by a Goblin High Priest who worshipped the Undead Monarch, making the transformation of goblin-class creatures into Bone Suckers a tradition.
But in reality, with slight modifications to the transformation ceremony, other humanoid creatures, including Giants, can become Bone Suckers.
Under normal circumstances, neither the Giant Bone King nor the Skeleton Dragon King would even allow these Bone Suckers a chance to approach.
They would directly manipulate skeleton remains to pierce them like a sieve or crush them by controlling their own bones.
