Pantosite - Everyone's Mega Stone

Pantosite

"An extremely rare Mega Stone, which is infused with such a variety of mystical energies that it is believed to be able to Mega Evolve any Pokemon that can."

"This Mega Stone glistens beautifully in sunlight, depending upon which angle one looks at it, different colours appear in different areas, but every colour is believed to be contained in this rarity."

This is a theoretical item for the world of Pokemon. I created it because of the increasing popularity of creating fake Mega Evolutions. If this continues, soon every Pokemon line will have a Mega Evolution - which would require a huge number of Mega Stones to be put in a game. So, here is the solution. One stone to evolve them all, one stone to find them, one stone.... wait. Different world. But yes, this would be a held item, which Mega Evolves any Pokemon which has a Mega Evolution. It is a little larger than the individual Mega Stones, to signify its greater power. The name Pantosite is derived from the Greek: παντός meaning all.
