In Subspace Emissary, it suddenly emerges from a lake after hearing Diddy Kong, who had been looking at the nearly destroyed Arwing nearby. It attacks the Arwing with an energy ball and grabs Diddy Kong. Diddy screams for help, so Fox McCloud, who manages to escape the damaged Arwing, leaps from it and breaks Diddy free of Rayquaza's grasp using Fox Illusion. Rayquaza, furious, launches another energy ball at Fox, who deflects it back at Rayquaza with his Reflector, causing it to fall back into the lake.
Fox and Diddy engage in a fight with Rayquaza, resulting in the second main boss fight of the Subspace Emissary. Some of its attacks involve burrowing into the ground and then bursting upwards. It also flies with great speed horizontally over the stage and sometimes drops a lightning bolt. The player can defeat it by attacking it around the head.
Although Rayquaza does not appear to have any connections with the Subspace Army, it is fought again in The Great Maze. Rayquaza also appears as both a trophy and a sticker, making it the only Pokémon that is neither playable nor summoned from a Poké Ball to have its own sticker.
Rayquaza also appears in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate as a hazard on the stage Kalos Pokémon League. It sometimes appears in the Dragon-type chamber, where it periodically flies from one side of the screen to another, damaging anyone that it comes into contact with. It also appears a trophy in Super Smash Bros. for Wii U and as a spirit in Super Smash Bros. Ultimate.
