Brinstar (ブリンスタ, Brinstar) is the default Metroid stage that appears in Super Smash Bros. Melee, Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS, and Super Smash Bros. Ultimate. It is a redesigned version of Planet Zebes from the original Super Smash Bros. In Ultimate, Zero Suit Samus is fought here for her unlock battle.
The stage has a similar appearance to Battlefield and consists of a main, rocky platform, two soft platforms on the side and a hovering metallic soft platform in the center. The main platform can be passed through from below, and it actually consists of two parts held together by a fleshy blob on the right side: said blob can be weakened by attacks, and when destroyed the main platform gets separated. The same can happen to the fleshy poles which keep the main platform and the side ones together: when they are destroyed, the platforms that were being supported tilt at a very sharp angle.
The destroyable parts will start to regenerate if they are not continuously attacked, fully growing back after a while. While regenerating, the substance that holds the stage together is fall-through.
Occasionally, an earthquake occurs and acid starts to rise, sometimes covering parts of the stage. The acid deals damage and heavy knockback on touch, though while it is rising it will prevent characters from being KO'd on the bottom blast line. It will rise and pause at various intervals, rarely reaching its highest point where it will cover everything except the topmost platform (and the tops of the side platforms if their supports are broken). After a while, the acid subsides.
In the back of the main platforms there are some ruins and a lone Chozo statue, which occasionally gets up and walks around with no gameplay effect. The background is occupied by a large pool of acid with an unidentified life form hanging above it. When the acid rises the brain-like creature may occasionally shake and even grow boils due to possible irritation from the acid.
Brinstar is considered the best Jigglypuff and Ganondorf stage in Melee (due to Rest combos with Jigglypuff and forward aerial combos with Ganon off the acid) and one of the better Mr. Game & Watch and Wario stages in Brawl (due to air camping beneath the platform).
If hazards are turned off in Ultimate the flesh is not destructible and the acid never rises in which players can always be KO'd at the bottom blast line no matter when.
Ω form and Battlefield form
In Super Smash Bros. for Nintendo 3DS, the Ω form consists of a completely flat and larger version of the regular form's middle platform. The acid never rises.
In Super Smash Bros. Ultimate, the Ω form and Battlefield form are set on a slightly redesigned version of SSB4's Ω form, but is resized and reshaped to match Final Destination and Battlefield, respectively. The three soft platform's designs are the same as the walkway of the main platform.
This stage is loosely based on the area Brinstar from Metroid and Super Metroid. However, its overall design is largely original to the Smash series; the only clear references include the yellow acid (featured in some rooms in Brinstar), the blocks with angry faces in the background (which originally appeared in Brinstar in Metroid, in the room where the Morph Ball is found), and the pillars at the sides of the stage (which behave similarly to the Zebetite pillars in Mother Brain's room in both games).
The acid rising up and down in this stage is similar to the acid in some rooms in Metroid II: Return of Samus that would lower upon Samus killing enough Metroids, and the acid in Mother Brain's room in Super Metroid that rose after earthquakes. A large part of Metroid's gameplay is exploration, which often involves destroying blocks with Morph Ball bombs to reveal secret passages: in particular, some blocks have a fleshy appearance similar to the one of the middle section of the stage.
In Super Metroid, Chozo Statues act as pedestals, carrying items in their hands. Some of them are able to walk, carrying Samus with them and enabling her to reach hidden areas, while others, called Torizos, are hostile and act as mini-bosses. In this stage, a Torizo is seen in the background and will occasionally walk around.
Brinstar used to be a counterpick stage, in both Melee and Brawl, due to the much more lax attitudes towards stage hazards and unorthodox stage designs. However, as time went on, characters such as Melee Jigglypuff, and Brawl Meta Knight, proved to be extremely powerful on this stage, as when the acid engulfs the main body of the stage, they can maintain extremely powerful control over the platforms with little to no risk of falling into the acid themselves. Additionally, in Melee, the ceiling glitch can cause players to be unfairly K.Oed at extremely low percents by the acid, and the much less forgiving ledge mechanics further benefited floaty characters due to the lack of walls for most recoveries to ride. Meanwhile, in Brawl, the stage would ultimately be banned due to the rapidly growing dominance of Meta Knight, and growing desires for a more conservative stagelist among regions in which the character was extremely common.
With the addition of the stage hazard toggle in Ultimate, Brinstar was initially considered for a counterpick due to the acid no longer being a factor, but its very small blast zones relative to the body of the stage cause greater volatility due to noticeably lower average K.O percents over the course of a match, and its heavily sloped surfaces can disproportionately favor short, small characters who are already difficult to attack. As a consequence, it is rarely, if ever, used in competitive play.
