Doburin

Doburin's skin is purple and her ears take the shape of webbed fins. She is bald, hiding a Daimon star mark on her forehead beneath a green and yellow swim cap, and rounds out the diver look with black goggles, a pink snorkel, an oxygen tank strapped to her back, and a pair of inflatable rings. A black one-piece suit bearing a red emblem completes the outfit.

She spits jets of water from her mouth and can bend that water to her will, snaring victims in it, dragging them down through whirlpools, or hurling it well beyond the pool that spawned her. The inflatable rings on her body serve as traps of their own, and she can harden the water into a yellow, wax-like solid that locks a target in place.

Kaolinite drew her out of the pool right after Ami and Michiru had finished a race there. Doburin ambushed Ami, freezing her inside amber-like water to draw out her crystal, but Tuxedo Mask snatched the Pure Heart away and sent the Daimon tumbling into the water. Luna and Artemis then bit and burst her flotation raft, leaving her thrashing near drowning, and Sailor Moon seized the moment to finish her with Moon Spiral Heart Attack. Like Thetis before her, she melts back into water when destroyed.
