Brinstar

BRINSTAR

Throughout the Metroid series, only a few areas have ever reappeared. One of the most common of these is Brinstar, the first area of Planet Zebes in both Metroid and Super Metroid, which also typically acts as the area where Kraid lives.

Super Smash Bros. represents the area well through their Brinstar stage, giving you a good visual grasp of what you can expect from any given Metroid game, with the Chozo statue in the background, the acid/lava rising and lowering, and the alien, almost-living platforms that provide just enough of an alien feel reminiscent of Alien movies and the art of H.R. Geiger.
