Gasceus haunts ancient temples dedicated to the worship of Pokémon in the past. It has been observed possessing statues and changing their positions, but to what end it does this is not yet known.

It is described in mythology as the Pokémon that shaped the universe with its 1,000 arms. When exposed to a strong wind, a Gasceus's gaseous body quickly dwindles away.
