Hirondeleor doesn’t have any natural predators left, since he killed them all. No one really knows what made this creature so lethal, but he's a danger to life in the ocean. Now he’s gotten greedy and he also wants to destroy the only creature that can pose a threat to him: Enypiast.

In battle, Hirondeleor is a very balanced attacker, with powerful skills that can make his enemies Bleed and have Nightmares. When infuriated, he can give himself a Damage Increase and even Double Damage that can make his attacks terrifying. Hirondelleor has the Hardened trait, but just in case that is not enough, he can also become Immune to Freeze!
