Crateria

Crateria is a starter stage in Super Smash Flash 2. It hails from the Metroid universe. It based on the surface location from Planet Zebes, a recurring location in the series, and is notably known for its constant never-ending raining and its acid rain.

Layout
The stage is somehow big and a bit complex compared to the Metroid stages in the past. It consists of 3 large platforms and a small floating platform that at times gradually moves around the stage. Occasional acid rains will also deal damage to players. However, they will not flinch. One can avoid taking damage from the rain by hiding behind the glasses underneath the ledges.

Music
The music that plays in Crateria is a medley consisting of 3 tunes from Super Metroid (Upper Brinstar, Crateria Underground and Lower Maridia). It also features, as an intro, the "Load Game/Start" tune from Super Metroid.

Origin
Crateria first appeared in the SNES game Super Metroid and is depicted as the surface of planet Zebes. It is a mountainous and rocky zone and contained many caves for Samus Aran to explore. It had little vegetation, except for grass and other small plants. After Tourian's destruction in "Metroid: Zero Mission", the landing site was constantly drenched by acid rain (most likely due to pollution from the destruction). This rain could not harm her due to the physical adaptations she had gone through while on Zebes. However, the Metroid Manga seems to suggest that acid rain has always been a part of Zebes. In the Wii game Metroid Prime 3: Corruption, Acid Rain is also present in the Space Pirate Homeworld and is a very hazardous substance as it can kill Samus almost immediately if she is exposed to it without the suit called the Hazard Shield. In SSF2, Crateria is shown as a dark, gloomy area that is barely illuminated, surrounded in the inner caves of planet Zebes; much like in Super Metroid, it is constantly raining on the stage with some alarm sirens sounding to warn fighters about the incoming acid rain. The fact the acid rain causes damage might have come from the acid rain from Metroid Prime 3: Corruption as opposed to the harmless acid rain from the original Crateria.

Trivia

 * Four different medleys were composed for this stage's music track. Ironically, the one that was included was the only version that did not include the original Crateria theme.
