Eevee Super Evolve

Unlike Mega Evolve, the Super Evolve is permanent. Super Stone has no sub-categories and only one of them exists on the Pokemon planet. It's location is currently unknown. After each Super evolution, the stone descends to the core of the planet and comes back up again in a new spot through volcanic eruptions. It is able to Super Evolve any Pokemon from the beginner stage to a Super stage. The capabilities of a Super Evolved Pokemon are enormously beyond Mega Evolved Pokemon.
