Hydruka

Hydruka are Rahi who are known to be ill-tempered.

Hydruka are herd Rahi of the inhabitants of Mahri Nui. They are used by the Matoran to harvest Airweed, which is used by the Matoran to create air bubbles for them to live safely underwater. They also have the ability to create Solidified Air Bubbles that can be launched at sea creatures. Hydruka are favorite prey for Ehlek's eels. Like Nocturn, they are unaffected by the mutagenic water surrounding Mahri Nui.
