Impalicus is a creature in the Kaijudo: Rise of the Duel Masters series.
Writhing Bone Ghouls are frightening creatures. With arms that curve into blades and a spiked skull, just its appearance has caused creatures to run away in horror. They are known for their aggression, attacking creatures of all sizes. Their incredible ferocity is so renowned that they have even managed to attract The Choten's attention for his experiments. There's no telling what devious plan he might use it for. The Choten tested his evolution serum on many different creatures. Writhing Bone Ghoul evolved into a significantly more dangerous form — Impalicus after The Choten used him in an experiment.
