Cockatrices are rooster/chicken and lizard combination ceatures. Yes, they fly! They are so awesome, most of their body is bird-like, but their tail and underbelly is lizard-like. They are so cool!
Many cockatrices were born on Azizi, the world of Origin, and they migrated to Whithith. All were hunted, the only ones that survived were the ones that did not enter that world.
However, there are rumors going about that there is one cockatrice that is still out there.
