The Seashocker is a medium-sized Tidal Class dragon that first appeared in How to Train Your Dragon 2.

Official Description

Supremely furtive, Seashockers share attributes with many of the the ocean's most extraordinary creature: the morphology of a Manta Ray, the sonar of a dolphin, and the bioluminescence of a deep dweller.

Similar to Hideous Zipplebacks, the Seashocker also possess two heads. But unlike their airborne cousins, Seashockers only have one thing on their twin heads: predation. If you ever see their dark fins amongst the waves, it's it's already too late for you - the rest of their pod has already moved in to attack!

Being water-based dragons, Seashockers do not breathe fire. Instead, their bites paralyze victims with an electrical charge that stuns even the biggest prey into submission. Perhaps this is the reason why all dragons fear the Seashocker's closest evolutionary relative - the electric eel!

Seashockers are wonderful ice-breakers, but not in the conversational sense -- their dorsal fins, comprised of super-dense cartilage, can cut through even the most frigid floes, allowing Seashockers to carve a path to any ice-bound prey.


A deep diver of the Tidal Class that travels in large groups (or pods). It emits underwater sonar to stealthily detect unsuspecting prey... or overboard Vikings!

The mighty Seashocker builds up a powerful charge of electricity that it unleashes on it's opponents in battle.
