Octillery is a red, cephalopod-like Pokémon with large, round eyes and a turret-like mouth. There are yellow bumps on its rock-hard head and yellow suction cups on each of its eight tentacles. These suction cups and yellow bumps are smaller on a female Octillery. It uses its tentacles for manipulating objects and the suction cups give it strong gripping power. Because of this, it is very hard for it to be blown away.
Octillery is a relaxed Pokémon who loves fuss from its Trainer. In the wild, it will spurt ink containing substances that dull predators' sense of smell to protect its young from danger. Even though it is more docile when domesticated, it can be very stubborn at times in the wild. It instinctively sneaks into rocky holes, and if it gets sleepy, it steals the nest of a fellow Octillery. It sometimes sprays ink on prey by sticking out only its mouth, and its suction cups hold prey tightly. Octillery is normally found in oceans. Octazooka is its former signature move.
It is thought to be a distant relative to Omastar.
Octillery debuted in Octillery The Outcast, under the ownership of Marcellus. It evolved from one of his Remoraid, a task that Marcellus had been spending the majority of the episode trying to do.
In The Pirates of Decolore!, an Octillery abandoned by its Trainer was a powerful member of Croconaw's pirate gang, and it would often battle any Pokémon it came across. It eventually joined Officer Jenny's new squad.
