Noctowl in depth
The Forest Zuku
Its Japanese name, ヨルノズク (Yorunozuku), combines 夜 yoru, night, with ズク zuku, the ending carried by Japanese names for horned owls — the same one found in 木菟. The English name is flatter and does the same job: nocturnal joined to owl. Both versions say exactly the same thing, which is unusual in this series, where the Japanese joke usually gets lost along the way.
The model is a forest owl, with the light feathers above its eyes acting as eyebrows and its chest striped in a zigzag pattern. Its upright posture and size point to the large Asian owls, and the head turn mentioned by the Pokédex is not a designer's exaggeration: real owls have fixed eyeballs in their sockets and compensate by turning their necks.
The Ten Points That Came Late
From the second through the sixth generation, its Special Attack was 76, for a total of 442. In the seventh generation it rose to 86 and the total became 452. It is one of those quiet tweaks Game Freak hands out every few years, and in this case it arrived late: the Ability that gives it purpose, Tinted Lens, had existed since the fifth generation, but the stat that could take advantage of it was not adjusted until two generations later.
It shares that Ability with Venomoth and Yanmega, which use it better because they have Speed and Special Attack to spare. On an owl with 70 Speed, Tinted Lens does not turn anyone into a threat; it just stops its two attacking types from crashing into resistances, and that is it.
The List of Moves It Learns on Its Own
The order in which it gets its attacks says a lot about what it is meant to do. Air Slash at 18 and Extrasensory at 23 are its first two proper special attacks. Roost at 38 restores half its health. At 43 it learns Moonblast, a Fairy-type move, which is unusual on a brown bird and one of the few ways it has to hit Dragon- and Dark-types. At 48 and 53 it finishes with Hypnosis and Dream Eater, the classic pair: put them to sleep first, drain them afterwards.
The problem with the combo is that Dream Eater needs a sleeping opponent, and Hypnosis's accuracy odds are not on its side. Against an opponent with Insomnia, the same Ability it can carry, the entire plan fails to get off the ground. In a single-player run, it works well enough to get through entire routes without taking damage.
The Owl Nobody Remembers
It is one of the second-generation species that appears early, gets used for twenty levels, and is replaced by something else before the League. Johto's early routes fill with Hoothoot as soon as night falls, and the player who keeps one has a decent Flying type early on and dead weight by the end. The cruel comparison is Xatu, which distributes its points in a similar way and hits quite a bit harder.
Even so, it has one quiet achievement: it is one of the few Pokémon with access to Insomnia, Keen Eye, and Tinted Lens at the same time, three Abilities that have nothing in common with one another. In Scarlet and Violet, it keeps its 452 points and a long TM list — Flamethrower, Shadow Ball, Psychic Noise, Tera Blast — that lets it cover things its typing could never reach.
