Nebatakos operates within the antagonistic organization Eternal in *Yes! Pretty Cure 5 GoGo!*. His human guise presents a stout, balding businessman with two side hair strands, consistently wearing an orange or honey-brown suit, maroon shirt, rose tie, brownish-black trousers, and red shoes. His true form manifests as an octopus-like entity featuring six tentacles serving as legs or whip weapons, moist skin, a jagged mouth, and an ink-shooting necklace.

He pursues thrills, readily ignoring collateral damage during missions and openly defying rules or protocols. This conduct sparks repeated clashes with his superior, Anacondy, often over reports and procedures.

His debut involves crashing into the Palmier Kingdom via meteorite to find the Rose Pact. There, he morphs a rock into a Hoshina monster to fight the Pretty Cure, captures Coco, but faces repulsion from King Donuts' light and Cure Aqua's Sapparrow Arrow.

Later, he infiltrates Cinq Lumière, delivering basketballs possessed by Hoshina. Chaos erupts after Kurumi (Milk) kicks one ball, leading to a battle resolved by Cure Dream, Rouge, Mint, Aqua, and Milky Rose. Nebatakos directly assaults the personal dreams of specific Cures: he sabotages Urara's acting aspirations, undermines Komachi's resolve to deliver Madoka's bag, and smashes Nozomi's cooking lessons.

His final arc sees him seeking vengeance against the Pretty Cure team following his dismissal from Eternal. This quest ends with his defeat and destruction by the combined Rainbow Rose Explosion attack from the Cures.
