Rayquaza is a Pokeball Pokemon for Smash Bros. Clash. He makes a re-appearance in the game, however with a slightly different personality. Once released, Rayquaza will fly up and go into the background. From there, he will shoot out a powerful green blast of Dragon Pulse to around the area he was released, that works in the same manner as Lugia's. This does decent damage and knockback so it's best to avoid him when he's not summoned by you.
