It is not known to evolve into or from any other Pokémon.
Farfetch'd resemble brown, cartoon-like Mallard ducks, but Farfetch'd is always brown regardless of gender. It has a large head in proportion to its body, it has a yellow beak, and it bears a black plumage on its forehead that resembles eyebrows. Its body and head are primarily brown in coloration and it has a white underbelly. It has wings as big as its body which appear to be prehensile enough to work like hands, and it always holds a leek in one of these wings. It also has yellow legs with webbed feet.
Its wings are a bit more versatile than most birds' as their feathers can be used as "fingers," allowing it to carry a leek, or spring onion. The leeks they carry can be used as a weapon, allowing them to use moves like Night Slash, Poison Jab, Fury Cutter, and Leaf Blade.
Farfetch'd are always seen carrying a leek stalk, or spring onion. They carry it in their wings, sometimes choosing to hold it in their beaks instead and holding it in their feet when flying. Farfetch'd cannot live without their stick for unknown reasons, and will defend their stick with their life. The stick is also known to be used as nesting material and as a weapon. In case of an emergency situation where the Farfetch'd is starving, it will eat its own stick and hurry off to find a new one.
They are known to be picky in the kinds of sticks they accept. Farfetch'd have been known to fight each other over one 'good' stalk.
Farfetch'd are found in grasslands, but it always has to be near water. Farfetch'd are also very good swimmers and are often found swimming in ponds. Farfetch'd are quite rare and are normally caught in Johto, although have been sighted in Kanto.
Farfetch'd are an herbivorous species, usually eating weeds and water plants.
