Rayquaza is a Pokémon species in Nintendo and Game Freak's Pokémon franchise, appearing in the 2002 video games Pokémon Ruby and Sapphire and subsequent sequels, later appearing in various merchandise, spinoff titles and animated, printed and film adaptations of the franchise. It is a legendary Pokémon. Rayquaza is the version mascot of the 2004 video game Pokémon Emerald. It is also the master of the Weather Trio, which contains Kyogre, Groudon and itself. It is known for being one of the strongest Pokémon in the franchise, since it is able to Mega Evolve and hold an item at the same time. This, together with the fact that Mega Rayquaza has the highest base stat total of all Pokémon, led to it being the only Pokémon to be banned from the community-selected Uber tier.
