Nihilego (Japanese: ウツロイド Uturoid) is a dual-type Rock/Poison Pokémon.

It is one of the Ultra Beasts and is known by the code name UB-01 Symbiont.

Nihilego is an Ultra Beast that resembles a jellyfish. The bell is semi-translucent and encircled with several white, star-shaped markings. The wavy rim of the bell flares outward and is bright blue. Its tentacles appear gelatinous and give it a vaguely humanoid shape. Several tentacles mesh together forming the appearance of long hair or a cape, while four shorter tentacles resemble shorter hair and arms. Two long tentacles make up the legs of the human-shape. In addition to its shape, it is sometimes seen acting like a young girl.

Nihilego has the ability Beast Boost, which boosts the bearer's highest non-HP stat by one stage upon knocking out a Pokémon. It shares this ability with the other Ultra Beasts.
