Hybodus

Overview
The Hybodus (Charcaradon Hybodus) was a carnivorous shark that lived from the Ordovecian period to the Cretaceous period. It is well-known for being the Descendant of The Uchiha Clan and its Kekkai Genkai. It appeared mid-Permian period along with the Hainosaurus, which is the Hybodus's greatest enemy. The Hybodus patrolled the oceans, ruthlessly killing everything on sight. It died off later in the Cretaceous period while having one last fight with the Hainosaurus.
