Sirfetch'd is an avian Pokémon that resembles a white duck, standing no taller than its pre-evolved form Farfetch'd and retaining its yellow beak, brown eyes, and eyebrow-like marking. Its legs and webbed feet are colored yellow, while the three-feather crest on its head and stubby tail are white. Its wings serve as humanoid hands, with the feathers at the end resembling fingers. It carries a massive leek in two parts, wielding the long, sharpened stalk as a lance and using the hard leaves as a shield.
It is said that this evolution was attained by Farfetch'd who have experienced and survived many battles. It is known to be calm and collected, preferring to fight fairly. Due to its noble nature, Sirfetch'd is often chosen as a motif for paintings; one famous painting in the Galar region shows a Sirfetch'd dueling with an Escavalier. The leek it carries is its most prized possession; it is used as both weapon and food, and maintained for many years. Once the leek finally withers, Sirfetch'd will retire from battle for good.
Sirfetch'd and Farfetch'd are the only Pokémon capable of using the Leek item.
Sirfetch'd can be seen as a parallel to Cursola. They are both mono-typed evolutions of regional forms whose original forms do not evolve. Bea uses Sirfetch'd in her team in Pokémon Sword in the Stow-on-Side Gym and during the Champion Cup Finals, while Allister uses Cursola in his team in Pokémon Shield.
Sirfetch'd appears to be based on a Pekin duck and a knight, with its leek halves resembling medieval weapons: a sword or lance and a shield. Like Farfetch'd, it may be inspired by the Japanese saying 「鴨が葱を背負って来る」, literally translating to "a duck comes bearing spring onions". As a saying, it means "easy target" or "golden opportunity". Sirfetch'd carrying a leek may also be inspired by the fact that the leek is one of the national symbols of Wales, part of the United Kingdom, which serves as the inspiration for the Galar region.
Sirfetch'd appearance may also be based on Sir Lancelot du Lac, one of the members of the Knights of the Round Table. In Arthurian legend, before he revealed his identity to King Arthur, he was known as the "White Knight" for his white armor. The Lancelot leek, which is a wild onion variant named after him, may also be referenced. Sirfetch'd's overall personality may be based on the code of chivalry.
The official Pokémon Sword and Shield website mentions a painting depicting Sirfetch'd battling an Escavalier; which may be based on the motif of knights fighting snails, which are sometimes found in medieval and Renaissance manuscripts, as well as Escavalier's own references to medieval jousting.
Sirfetch'd may be a combination of sir and far-fetched or Farfetch'd.
Negigaknight may be a combination of 葱 negi (spring onion), the prefix giga-, and knight. It may also be a pun on 葱がないと negi ga nai to (must have a spring onion).
