Farfetch'd is a Flying type Pokemon from the Kanto region. It is known for carrying around a scallion. Farfetch'd is not very strong and is not seen as a useful Pokémon.
Its name comes from the phrase far-fetched, perhaps referring to its rarity.
Farfetch'd is always seen with a stalk from a plant of some sort. Apparently, there are good stalks and bad stalks. This Pokémon has been known to fight with others over stalks.
In Generation VIII, it's discovered that it has its own Galarian form which is a Fighting-Type, and can evolve into Sirfetch'd after landing 3 critical hits in a battle.
