Tsunawataro is a Remless sent by Fish Eye to fight the Sailor Scouts. His only attack is forcing people to walk on tightropes, as well as walking on one himself, and is quite skilled at doing so. He appeared in Sailor Moon Super S Episode 10, Phony Fairy.
When Fish Eye looked through the dreams of an artist for Pegasus, she didn't find him, so she decided to kill the artist. Sailor Moon and Sailor Mini Moon arrived at the scene, so Fish Eye summoned Tsunawataro and left. Tsunawataro made Sailor Moon walk on a tightrope, but Tuxedo Mask attacked him. He fell off the tightrope, and so did Sailor Moon. Tuxedo Mask caught Sailor Moon while Tsunawataro fell and hit the ground. Sailor Mini Moon used Crystal Twinkle Bell to summon Pegasus, and Sailor Moon destroyed him with Moon Gorgeous Meditation.
- Tsunawataro is the first male Remless, and also the first male monster of the week since the droids Doom and Gloom from Sailor Moon R. This is because he is the first of Fish Eye's Remless, and all her followers are men, unlike those of Tiger's Eye and Hawk's Eye.
- His skin color is similar to that of Bojack from the Dragonball Z movie Bojack Unbound , as well as transformed DBZ villain Garlic Jr.
