Delta Stream (Japanese: デルタストリーム Delta Stream) is an Ability introduced in Generation VI. It is the signature Ability of Mega Rayquaza.

Effect

In battle

When a Pokémon with Delta Stream enters battle, the Ability creates strong winds, a unique weather condition. The strong winds last as long as the Pokémon with Delta Stream is in battle.

Strong winds cause the moves Sunny Day, Rain Dance, Hail and Sandstorm to fail and cause the Abilities Drought, Drizzle, Sand Stream and Snow Warning to fail to activate. If either Desolate Land or Primordial Sea are active, Delta Stream will override both abilities when Delta Stream activates. They also cause moves that are super-effective against Flying-type Pokémon to only deal normal damage to Flying types.
