Destrachan

Do not be fooled their somewhat unorthodox appearance or garish colors: the destrachan is a fearsome predator of the depths. Their mastery of their sonar capabilities is such that they can produce the frequencies required to shatter glass, crumble stone, and dissolve metal with little to no difficulty.

When hunting, they can modulate their vocal frequency so as to disrupt the very air itself, resulting in a shockwave of explosions as the water in the air is instantaneously boiled by way of resonant frequency. When pressed, destrachans resort to their claws rather than their sonic attacks, and while not as deadly as their harmonics, they can still rend flesh with relative ease.

As a side effect of having such destructive powers, destrachans themselves are highly resistant to kinetic force: explosions will do little to faze them.
