Totally Kool Dragons

Yook is the Water Dragon who used to be a koi fish.  He earned the right to be a dragon when he swam up the Great Waterfall.  His tenet is perseverance and his color is blue-green.  He is often dreamy and soft-spoken, and always kind.

When Yook is calm, he looks a little like a sweet seahorse with green scales and an ice-blue spine.

When Yook is ready to go into battle (or the sparring ring), he transforms into his fighting mode, Kyorugi Yook.  Tendrils stream from his eyebrows and whiskers, and his spine resembles a shock of seaweed streaming from his back.
