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 primarily out 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.
In the Hoopa's Surprise Ring Adventures short In the Dark, multiple Litwick were summoned by Hoopa in order to light up a dark cave for Ash. However, Hoopa summoned so many that it rudely awakened a group of Noivern, Noibat, Sableye, and Carbink.
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.
Litwick is tied with Yamask for the lowest base Attack stat of all Ghost-type Pokémon. Likewise, Litwick ties with Zen Mode Darmanitan for the lowest base Attack stat of all Fire-type Pokémon.
Litwick may be a combination of lit (past tense of to light) and wick. Lit might also refer to little, while wick might 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]).
