Norfair
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
Norfair is the name of a location on Planet Zebes in the Metroid series, and a stage in the upcoming, Super Smash Bros. Brawl. Very little is known about this stage, at this point. What is known, however, is that the stage takes place in a cavern filled with lava, and the players fight on a metallic platform. It is assumed the lava on the stage may rise up, as was the case with the acid in the Brinstar and Planet Zebes stages in previous Super Smash Bros. games.
