Noctowl is a nocturnal Pokémon, and has large red eyes that can see in pitch-darkness. Called "the emperor of dark nights" by some, it never lets its prey escape. It has exceptional hearing and eyesight, can fly silently and twists its head at a 180° angle to increase its intellect. It can also turn its head upside down, which signals that it is troubled by something. Noctowl is most commonly found nesting in trees and forests. It pecks those who disturb it.
Noctowl debuted in Fowl Play!. A man was trying to capture the smaller, Shiny Noctowl with traps, but kept failing due to the Owl Pokémon's intelligence. After Team Rocket was sent flying, Noctowl allowed Ash to have the chance to catch it. After an intense battle, Ash succeeded.
