Litwick is a small, candle-like Pokémon with a purple flame atop its head, which is powered by life energy that it absorbs. Its body and two stubby arms are made of primarily of white wax. The folded, melted wax lays over its right eye, and leaves only the bright yellow left eye visible. It has a small smile under a protruding upper lip. Litwick pretends to guide people and Pokémon around by illuminating darkened areas. However, it is actually sucking away their life energy and leading them to the Ghost World. In the anime, the flame is shown to grow as it continually absorbs life energy.
Litwick, the Candle Pokémon. Litwick appear to be helping to guide the way of people by illuminating areas that are darkened, but in reality they are actually leading them to the Ghost World. They feed off the life energy of people and Pokémon, and use it as fuel for the flames on their heads.
This concludes the entries from the Best Wishes series.
Litwick is a combination of hitodama (a blue, black, or purple-fire associated with ghosts and yōkai, equivalent to the western will-o'-the-wisp) and a candle. It may also be based on the cliché of ghostly floating candles.
Litwick may to be a combination of lit (past tense of to light) or little and wick. Wick might also refer to wicked.
Hitomoshi may be derived from 火点し hitomoshi, which means to light a lamp but also describes the person who leads a funeral procession in Japan with a torch, matching its Pokédex entry saying it leads people astray and then sucks out their life force. It may also derive from 人燃し hitomoshi (to burn a man [to death]).
