Puko

Puko is a Remless sent by Tiger's Eye to fight Sailor Moon.

She has the appearance of a humanoid balloon, and is completely round when fully inflated, and suffocates her victims. She appeared in Sailor Moon Super S Episode 5, Perfect Couple.

When Tiger's Eye targeted Saori to look for Pegasus in her dreams, Sailor Moon and Sailor Mini Moon came to stop him, so he summoned Puko to kill them. Puko tried to suffocate Sailor Mini Moon, but was thrown off her by Sailor Moon, and then went after Darien, but Sailor Moon jumped in front of him and was nearly suffocated, when Darien stabbed her with a knife that Tiger's Eye had earlier used to pin him to the ground. Puko was deflated because of this, but reassumed a humaoid form. Rini summoned Pegasus with Crystal Twinkle Bell, and Sailor Moon destroyed Puko with Moon Gorgeous Meditation.

Puko has a cousin named Sea Lion, who resembles a beachball.

Also has a sister named Peropero.
