Awesome substitute for Owlicious. I remember being so disappointed when I realized that Noctowl wasn't Psychic/Flying but instead Normal/Flying. Since then I've never been able to appreciate Noctowl, myself.
Even so, Noctowl has a very impressive move pool. It can learn psychic and zen headbutt, and sky attack. If anything, being a normal type gives it an advantage over the weaknesses of a psychic type against ghosts and dark types.
I know, it's just that by then we already had Pidgey, Spearow, Doduo and Farfetch'd who were Normal/Flying and after that we got even more of them in the third, fourth (ugh!) and fifth generation. Sure, we got Natu in the second, but even so; ten years later and I'm still not over it.
