Poipole is a small, purple Ultra Beast. It has a bipedal build with a large head and relatively small limbs with no visible digits. On its head are three spikes: one in the front and one on each side. A single gray needle protrudes from the top of its head and there are additional needles in the spikes on the sides of its head. It has oval eyes with a single eyelash-like spike above each; its mouth and eyes give off a cyan glow. It has a long, tapering tail with a single spine in the middle. While most of its body is dark purple, it has several fuchsia markings: at the tip of each head-spike, on its chest, on top of its head, and on its face.
Poipole originates from Ultra Megalopolis in Ultra Space, where it is popular as a First partner Pokémon. It is capable of understanding human speech after spending enough time with humans. Poipole's large head is filled with a glowing, adhesive poison, which it can fire from the needles on its head. While spraying opponents with this venom, it laughs wildly.As seen in the anime, Poipole can also shoot a harmless multicolored substance as a way to paint and even communicate to humans and Pokémon. It's shown to have the habit to stand upside down and spin rapidly as a sign of happiness and excitement. Like all Ultra Beasts, it stores an energy within its body similar to the aura seen around Totem Pokémon. This energy is called Z-Power. In The Shape of Love to Come!, it is revealed that wild Poipole live in large numbers in huge nests that resemble wasp or hornet nests alongside Naganadel, serving as a queen.
