Gastly
Sun

Should a strange light be seen flickering in an abandoned building, Gastly is lurking there.

Moon

Although Gastly is barely visible, when it’s near, a faint sweet smell lingers.

Ultra Sun

It’s said that gas emanating from a graveyard was possessed by the grievances of the deceased and thus became a Pokémon.

Ultra Moon

Poisonous gas comprises 95% of its body. It’s said that the remaining 5% is made up of the souls of those who died from the gas.

Lets Go Pikachu/Lets Go Eevee

Said to appear in decrepit, deserted buildings. It has no real shape, as it appears to be made of a gas.
