Skrill

The Skrill is a dragon that charges itself with electicity and rides lightning bolts to reach supersonic speed. It is a villain in DreamWorks Dragons: Defenders of Berk. It appeared in the episodes View to a Skrill Part I and View to a Skrill Part II.

Description
It is written under the strike class for its ability to ride lightning bolts like air torpedos, intelligence, and jaw strength. This elusive dragon has large wings, a spiked back and tail, and a large mouth. The spikes on the Skrill's back and tail are sharp enough to cut with the slightest abrasion, and it is an excellent flyer. It apparently resembles a Night Fury in flight and rivals its speed, being slightly slower. Like the Monstrous Nightmare, its locomotion on land resembles that of a pterosaur, using the large claws on its wings to walk and run on land.

As with most of the dragons in the manual, it is listed as being "extremely dangerous" and the manual instructs readers to "kill on sight". It slightly resembles a Thunder Drum, and its head also resembles that of a Deadly Nadder. When a Skrill is riding lightning, it seems to wrap itself in its wings and dive down.

Defenders of Berk
In A View to a Skrill Part I, A Skrill was found trapped in an iceberg by the Berserkers. Bucket and Mulch, who thought the Berserkers had crashed into an iceberg, came to help until they saw the Skrill. The Berserkers then fought Bucket and Mulch and were easily overpowered by the duo. The dragon riders arrived and the Berserkers retreated. Mulch then showed Hiccup and his friends the frozen Skrill. The dragon riders took the frozen Skrill back to Berk and placed it inside the Dragon Training Academy. The Skrill was later freed by Barf and Belch and Ruffnut and Tuffnut. The dragons and their riders try to keep the Skrill caged in but it managed to escape into the wild.
