when flaroreon was a eevee, he liked swimming with his old trainer, his trainer also liked flareon and vaporeon. one day flaroreon's trainer tried making a potion with parts of a water stone and with parts of fire stone. when the potion was done, his trainer made a meal for him to eat while adding some of the potion onto it, flaroreon ate it then grew into a big fusion of flareon and vaporeon (or you can just call it flaroreon). flaroreon got better at swimming because of this and ran away to a city in kalos because there was a swimming tournament in one of the cities, flaroreon's trainer never saw flaroreon again.
