"Its eyes are specially adapted. They concentrate even faint light and enable it to see in the dark."
Noctowl is one cool Pokemon, especially if you remember how it was in the anime. It was actually Ash's first and only Shiny Pokemon. Plus, his Noctowl was incredibly smart, using Hypnosis on any who tried to catch it, including Ash. He eventually did catch it though, and it helped him in many battles, including Gym and League battles.
Noctowl's Basic Attacks are Extrasensory and Wing Attack, while its Special Attacks are Psychic, Night Shade, and Sky Attack.
