Mega Stone used to evolve Lucario into its Mega Counterpart, Mega Lucario. The Lucarionite is an item that is not normally obtainable in-game without the means of cheating or hacking. It is the first non-event Mega Stone revealed for Pokémon X and Pokémon Y. The Lucarionite was revealed to be a held item in the trailer it was introduced in, as was its flavor text.
|Flavor Text||One variety of the mysterious Mega Stones. Have Lucario hold it, and this stone will enable it to Mega Evolve during battle.|
