Pokémon Omega Ruby & Alpha Sapphire — 02 October, 2014

Following on from the recent reveals of Primal Groudon/Kyogre and their abilities/moves, Rayqauza has now been confirmed to receive a Mega Evolution!
Mega Rayquaza remains Dragon/Flying type but gains a brand new ability,Delta Stream, which creates a new weather conditionstrong winds. Just like Desolate Land and Primordial Sea revealed previously, the strong winds summoned by Delta Stream cannot be removed by normal moves or abilities while Rayquaza stays in battle – in fact Delta Stream appears to take priority over Desolate Land and Primordial Sea.
Strong winds also reduce damage from the types Flying is normally weak to (Electric, Ice and Rock) to any Flying type Pokémon in battle.
Rayquaza also has a new moveDragon Ascentwhich is Flying type and apparently will be the most powerful Flying type move in existence (which currently is Sky Attack at 140 base power). Check out the official video below:
