Kraid

Kraid is a monster with reptilian-like attributes from the Metroid franchise. In the Super Smash Bros. games, Kraid is a hazard in the stage Brinstar Depths, which appears in Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. Ultimate. Here, Kraid rises out of the magma and rotates the stage by hitting it. Fighters who are not quick enough fall into the magma pit and are KO'd.
