Rayquaza (レックウザ, Rayquaza) is a fictional creature from the Pokémon media franchise.
Rayquaza is a legendary Pokémon that debuted in the third generation of Pokémon games, serving as the version mascot for Pokémon Emerald, the third special edition game to Pokémon Ruby and Sapphire, and is categorized within the Pokédex at #384 as the "Sky High Pokémon". A green, serpentine creature, it is part of a trio of legendary Pokémon commonly referred to as the weather trio along with Groudon and Kyogre, and in its games is able to mediate the fights between those two. Its types are Dragon and Flying. It is considered very territorial and usually flies around in the ozone layer.
Rayquaza first appeared in Pokémon Ruby and Sapphire as a legendary Pokémon residing in Sky Pillar. However, it did not have much of a role in these games. In the fifth Pokémon game of Generation III, Pokémon Emerald, Rayquaza is the mascot and served a much bigger role, becoming the one who stops the fight between Kyogre and Groudon. It also stays in Sky Pillar once the conflict is finished and can be obtained much earlier.
Role in The Subspace Emissary
Rayquaza is the second boss in The Subspace Emissary in Brawl. In the mode, Rayquaza first appears in the level The Lake after Diddy Kong goes to investigate a crashed Arwing. Seeing Diddy and the Arwing's pilot as intruders of its territory, Rayquaza bursts out of the water, destroys the Arwing with an attack resembling a ball of energy, and then grabs Diddy. Before it can retreat into the water, Fox leaps from the burning Arwing and attacks Rayquaza using Fox Illusion, causing it to lose its grip on Diddy Kong. The beast attacks Fox with the energy ball attack again, but Fox reflects the attack back at Rayquaza using his Reflector, sending it tumbling back into the water. Both Diddy and Fox face off against the dangerous legendary Pokémon.
Even though it wasn't working for the Subspace army, Tabuu brings back Rayquaza to slow down the heroes in The Great Maze.
Also, when Rayquaza is defeated, it twitches at the last second, which probably means it was only knocked out (a possible throwback to the Pokémon series, where a Pokémon who is defeated in battle is said to have fainted).
It can also be battled at any given time in Boss Battles Mode.
Rayquaza's attacks & stats
Like all bosses, Rayquaza can be controlled in Boss Battles Mode by hacking. The start button will, like all bosses self-destruct it.
HP and damage taken
While Rayquaza technically has less health than later bosses, its massive battery of resistances practically gives Rayquaza a very large amount of health. In fact, the only moves which it does not resist are those with freezing hitboxes, which is a nod to the Pokémon games where Rayquaza's typing makes it weakest to Ice-type moves. However with there being only a few moves in the game with hitboxes of the freezing type, only possessed by the Ice Climbers and Lucas, this lone relative weakness can rarely be exploited. Even then those few freezing moves are projectiles, meaning Rayquaza will still resist them, while also being low-damaging and laggy moves that would make them ineffective for using against bosses. With this inability to use moves that Rayquaza doesn't possess an at least x0.7 resistance to, it is effectively about as or even more durable than Duon, the most durable boss outside of Tabuu.
None of Rayquaza's hurtboxes are programmed to be a weak point, though interestingly it has weak point numbers programmed in that are not the default ×2.0 like they are for other enemies that lack a weak point. This may indicate that Rayquaza originally had a weak point to counterbalance its massive resistances, that was scrapped late in development.
Like all bosses in Brawl, Rayquaza gains an additional ×0.6 damage resistance modifier when fought in co-op mode, effectively gaining 67% more health. This modifier is applied whenever the second player is in-game, and is no longer applied if the second player loses all their stocks.
Rayquaza's trophy must be obtained by using a Trophy Stand on it during its Subspace Emissary fight.
As a stage element
Rayquaza appears in the Kalos Pokémon League stage as a stage element. Appearing rarely in the Dragonmark Chamber, it flies across the stage at various angles, dealing damage to fighters. Its path is shown briefly by lightning before it appears, giving players time to avoid it.
