Octiler's tough, crown-shaped ridge on its head keeps it from being able to squeeze fully through tight spots to escape predators. Instead, it incorporates the shed shells of crustacean Pokémon into armor for offense and defense.

It waves its huge, oversized claw in the air to communicate with others. It ensnares its foe with its suction- cupped tentacles before delivering the finishing blow.
