Frequently found haunting shipwrecks, Gaseon is a surprisingly peaceful creature. It often will attempt to guide the spirits of lost Pokémon to the water's surface with bubbles in order to allow them to rejoin their Trainers in the afterlife.
Gaseon underwent a spontaneous mutation and grew fins and gills that allow them to live underwater. When exposed to a strong wind, a Gaseon's gaseous body quickly dwindles away.
