Planet Zebes: Brinstar

Brinstar is the default Metroid stage that first appeared in Super Smash Bros. Melee. This stage is based after a section of Zebes. This stage has a base platform, two sides held by fleshy stalk-like poles, and a hovering metallic platform. There is another fleshy substance in the middle of the base platform that holds the stage together. The main obstacle is a ocean of acid in the background which occasionally surfaces and will burn opponents. There is also a lone Chozo statue in the background which occasionally gets up and walks around. The fleshy stalk-like poles and substance can be destroyed to separate the platforms and break the stage in half. Both of the destructable substances will start to regenerate if they are not continuously attacked. After being destroyed, they will grow back once a certain amount of time has passed.

Brinstar has many similarities to Planet Zebes of SSB. As Brinstar is also available at the start of Super Smash Bros. Brawl as a Melee Stage, this makes it one of only two stages that has been playable in all three games, the other being Corneria.

Trivia

 * There are several references to Mother Brain in this stage. The fleshy stalks that connect the platforms have all the characteristics of the 'Zebetites' (life veins of Mother Brain) that Samus had to break before reaching the final boss in Metroid and Super Metroid. Also, it is popular belief that the gigantic alien organism in the far background is actually Mother Brain itself. Although this is unconfirmed, the behaviour of the organism is very similar to that of Mother Brain during the battle against it.
 * If the poles on either side of the stage are broken, the platforms that were being supported shall tilt at a very sharp angle.
 * The Chozo's design and actions come from Super Metroid.
 * Near to the Chozo Statue are bricks with angry faces. These appeared in the famous "Morph Ball room" in the original Metroid.
 * In Brawl, when a player selects the Pokemon Trainer, the Trainer himself is situated on a brand new platform in the background, which is not usually there.
