Myrka

The Myrka was a large species of reptile that was used by the Silurians for heavy backup in times of war. They were genetically modified by the Silurians from an unknown deep-sea creature.

Overview
Myrka were reptilian creatures with thick, rubbery skin, four legs, two arms, a long tail and a large head. They were taller than a human and much longer than a horse. They had wide, pale eyes and a large fin on their head. Under their chins and around their body they had strange kelp-like growths. Myrkas were well adapted to deep-sea life, with large webbed feet, a flat tail and a powerful body.

Myrkas could create powerful electrical charges. These charges were powerful enough to kill a human, but the target needed to be close or touching metal which the Myrka was also touching.

Because they were created from a deep-sea creature, their skin withstood a lot of damage. They were highly bullet-resistant, and could take out a missile by themselves. They could also survive on land, but they moved slowly and had trouble staying upright. On the other hand, due to their origin, they were very susceptible to bright lights and UV rays. Small amounts stunned and potentially blinded them, but large amounts killed them outright. (MA: The Scales of Injustice, DW: Warriors of the Deep)
