{Short note of explanation: The following is a complete rewrite of the pidgey line’s pokédex entries, rather than simply an entry for mega pidgeot. This probably won’t be a common thing but rather just a thing that might happen from time to time with the least funny entries. Sorry! Carry on!}
Pidgey
The Tiny Birb Pokémon
Type: Normal/Flying
Official Registration #: 16
Entry: A small, extremely common bird-like pokémon native to Kanto. This pokémon is popular among younger trainers, not only for how easy it is to catch and train but also because humans apparently take delight in calling a nearly direct descendant of the majestic dinosaur pokémon “birb,” “smol boi,” and/or “four pounds of whoop-[EXPLETIVE].”
Pidgeotto
The Birb Pokémon
Type: Normal/Flying
Official Registration #: 17
Entry: The evolved form of pidgey, by battle experience. The crest on its head is a set of feathers that help stabilize this pokémon during high-speed flight. However, the author will not discourage anyone from assuming that they are “leafs” that pidgeotto “wears on its head to enhance its beauties.”
Pidgeot
The Birb Pokémon
Type: Normal/Flying
Official Registration #: 18
Entry: The evolved form of pidgeotto, by battle experience. The author can neither confirm nor deny whether or not this pokémon would sell its trainers to Giratina for one corn chip, but he can say it’s more likely for pidgeot to do it than honchkrow.
Mega Pidgeot
The Birb Pokémon
Type: Normal/Flying
Official Registration #: 18+
Entry: The advanced form of pidgeot, via pidgeotite. This bird-like pokémon keeps itself in the air by sheer force of anger alone. You may think the author is quoting yet another bird-themed meme, but actually, no, that is a literal and scientifically accurate statement.
