Reveevee's three evolutions! they are based on the three original Eeveelutions, but they are very different...

When a Water Stone fits the missing piece in Reveevee’s head, it evolves into Revapor. Revapor are often told in old tales of Kasal, of a sea spirit that spirits away anyone who goes too close to the water on quiet, moonless nights. Because of this, it isn’t recommended to visit watery places during the night in fear of the stories being true. Revapor hides itself in its own water, and strikes prey when they least expect it.

When a Thunder Stone fits the missing piece in Reveevee’s head, it evolves into Revunder. Revunder’s forked tail acts as a giant lightning rod, drawing in lightning from thunderstorms. When provoked, it can shoot out all the lightning from its tail in a single burst, and it is told in old tales to appear before those doomed to die by lightning, seemingly wanting to bring the remains to the afterlife.

When a Fire Stone fits the missing piece in Reveevee’s head, it evolves into Revlare. Revlare’s body emits a constant scent of burning, so much so it causes irritation if standing beside one for too long. It has been known to set trees ablaze and to feast on the burned wood afterward; this gives Revlare strength. However, it has been known to cause forest fires because of this.
