To all "Pokémon Omega Ruby" and "Pokémon Alpha Sapphire" fans, there's new information about Mega Rayquaza. The details were revealed during a live stream for "Pokémon ORAS."

In the live stream, it was seen that Mega Rayquaza has a different way of achieving its Mega Evolution. However, the game developer still wants the evolution method to be kept a secret — a secret that can be unlocked while playing the game.

Meanwhile, all the new details for "Pokémon Omega Ruby" and "Pokémon Alpha Sapphire" are in the official website. There, it describes the boosted stats for Mega Rayquaza due to its Mega Evolution. Its Attack and SP stats increase.

There's one very special ability that players should be excited about when it comes to Mega Rayquaza. The ability is called Delta Stream. This ability can bring forth strong winds to change the weather. On top of that, Delta Stream will help fail skills like Hail, Sunny Day, Rain Dance, and Sandstorm. Further, Drizzle, Snow Warning, Drought, and Sand Stream will not activate.

Players can head on over to the official website to see a couple of screenshots of Mega Rayquaza and his skills. In the meantime, "Pokémon X and Y" should keep gamers busy with some Halloween competitions. There's the Trick or Treat Battle Competition, wherein players from Europe and the U.S. can join in.

The Trick or Treat Battle Competition will feature Pumpkaboo, who has an insomnia ability. This competition will last throughout October.

Another event will be the Hoenn Pokémon NicoNico Match, which will be specially catered to Japan players. This competition will feature Double Battles. Players can use Pokémon between 252 and 384 under the National Pokédex.

The competition will run from Oct. 10 to 14. Registration will be on Oct. 10. The reward for participants is 2525 Hoenn Poké Miles.
