Skrill

Hidden Abilities: They can hibernate in icy glaciers for decades at a time, and emerge as fierce as the day they were frozen.

One of the most mysterious and feared species in the Book of Dragons, the Skrill is aggressive, powerful, and nearly untrainable. Skrills do not breathe fire. Instead, they channel lightning down their metallic spines, firing it from their mouths in a shower of destructive blasts. They can also store this electrical power in their bodies and release it later on. Because of this unique firepower, Skrills tend to gravitate towards stormy weather. If you find yourself flying through a thunderstorm, watch out! Skrills are also tough. They can take a lot of damage in battle, and give as good as they get. However, the Skrill has one weakness...it cannot fire its lightning from the water. Force a Skrill into the ocean and it loses the upper hand.
