Adaro – The Adaro are mean half-man and half fish spirits. They had the overall shape of a human male with gills behind their ears and a shark-like dorsal fin on their backs. They also had fins for feet and a spear growing out of their head.

They would live in the Sun and travel back and forth to earth on rainbows. These hybrid creatures were known to kill humans by shooting poisonous flying fish into their necks.
