Fletchling is a small bird-like Pokémon. It has a bright orange head and a mostly pale purplish-gray body. The tips of its grayish wings are white, and it has a small black and white striped tail. It has round black eyes, a small black beak, and tiny black feet and talons.
Fletchling is highly docile and fond to people, especially trainers. They emit beautiful chirps to listeners and bird-watchers. In battle, Fletchling is volatile, being hasty, swift and relentless. Fletchling is shown to have great determination, as it hardly shows any signs of "chickening-out" from battles.
Fletchling resembles the Flying-type Pokémon sprite in Red and Blue versions.
Fletching's name is purely based from the word "fletch", a material (commonly in the early age when they used pure tail feathers) in archery that serves as the stabilizer for the arrows, while "hatchling" is a newborn animal that is born from an egg (commonly baby birds are referred to as hatchlings). Its small-size body may refer to itself as a "hatchling" while its "fletch" shape and stylized diagonally striped tail is very similar to the fletching of an arrow.
