Pidove
The Tiny Pigeon Pokémon
Type: Normal/Flying
Official Registration #: 519
Entry: A small, pigeon-like pokémon endemic to the urban areas of Unova and Kalos. Notorious for its forgetfulness, pidove have a tendency to wait for their next orders, even if a trainer had already issued one. They also have the tendency to forget that they can fly, that the window they had flown into three seconds earlier exists, that purrloin eat them, and practically anything at all if shown a small chunk of bread.
Tranquill
The Wild Pigeon Pokémon
Type: Normal/Psychic
Official Registration #: 520
Entry: The evolved form of pidove, by battle experience. Tranquill are known for being excellent messengers, largely because they possess the ability to return to their trainers, regardless of how far they have to fly in order to do so. Given the forgetfulness of tranquill’s previous evolution, this has naturally baffled behaviorists for centuries. Less baffling: the fact that tranquill don’t seem to take “it’s amazing that you can remember you have your trainer, given, you know, what you were like as a pidove” as a compliment.
Unfezant
The Proud Pokémon
Type: Normal/Flying
Official Registration #: 521
Entry: The evolved form of tranquill, by battle experience. The sexual dimorphism of this pokémon has been a point of interest to pokémonologists for years. Males possess elaborate, brightly colored plumage, which they show off during mating season by swinging their heads in a display designed to simultaneously attract females and threaten males away from mating candidates. The females, meanwhile, possess duller plumage but stronger wings, the latter of which grant them flying abilities that are practically unrivaled among bird pokémon, their male counterparts included. To be fair, though, it’s perfectly understandable. Whenever certain subsets of the human species display similar behaviors to male unfezant, their potential mating candidates, too, display impressive flight abilities for the sake of evacuating immediately, and the author, to be frank, can hardly blame them.
