Mega Rayquaza

Type: Dragon/Flying
Classification: Sky High Pokémon
Height: ??
Ability: Delta Stream

Rayquaza's connection to the mysteries of Mega Evolution is still a subject of discussion. The Legendary Pokémon Rayquaza is said to achieve Mega Evolution in a unique way—unlike that of other Pokémon—due to its unique biology. This unique method and the mystery of Mega Evolution will become clear as players go along the story.

Rayquaza is a Pokémon distinguished by its high Attack, Sp. Atk and great overall stats. After Mega Evolving, its two excellent stats gets significant boost and almost all of its other stats get a good increase as well.

Particles stream from the long filaments that extend from its jutting jaw. These particles can control the density and humidity of the air, allowing Rayquaza to manipulate the weather. Its green hide sparkles with an emerald-like quality.

Mega Rayquaza's ability is Delta Stream which fills the air with mysterious strong winds that affect the weather. These strong winds cannot be dispelled by changing the weather condition, except by a very limited number of Pokémon. Only Mega Rayquaza has this ability.

Deltra Stream effects:
  • The weather stays active as long as the ability-bearer remains in battle, but stops when the Pokémon is switched out.
  • The moves Rain Dance, Sunny Day, Sandstorm, and Hail will fail.
  • The Abilities Drizzle, Drought, Sand Stream, and Snow Warning will fail to activate.
  • Electric-, Ice-, and Rock-type moves deal normal damage to any Flying-type Pokémon in battle instead of being super-effective..

Also, with Delta Stream, weather effects last indefinitely as long as Mega Rayquaza remains in battle. When it is swapped out for another Pokémon on your team, the weather immediately returns to normal.

This is different than the Abilities Drizzle, Drought, Sand Stream, and Snow Warning, which can all affect the weather for five turns after being activated in battle, regardless of whether the Pokémon with these Abilities are still in battle or not.

The Delta Stream Ability and the Air Lock Ability are different in that Delta Stream fills the air with strong winds for as long as Mega Rayquaza remains in battle. Air Lock cancels out all weather-condition effects for all of the Pokémon in a battle as long as Rayquaza remains in the battle.

Dragon Ascent is Rayquaza's signature move. It boasts one of the greatest power ratings of all Flying-type moves, putting it at the top of its class. Not only will you be surprised by its overwhelming power—you'll be mesmerized by its majestic appearance! After soaring up toward the heavens in a great burst of speed, it crashes down in attack, dealing massive damage.
