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.
Fletchling's eye looks similar to another bird. For instance, when it looks from the left side, the bird on its eye looks right.
In Super Smash Bros., Fletchling is one of the Pokémon that can be freed from Pokéballs. During this time, it uses the move Peck.
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.
