Orpheon

From Wikitroid, the Metroid wiki

Orpheon is the name of a Space Pirate frigate Samus receives a distress signal from in Metroid Prime. It is featured at the beginning of the game. The vessel is operated by Space Pirate Science Team as a transport and research vessel and was key in the transportation of Metroid samples from the fallen base of Zebes to the research facilities on Tallon IV. Other than Metroids, the vessel housed various other bizarre species that the Space Pirates were running tests on, most likely for militaristic purposes; the most notable being the Parasite Queen. Phazon could also be found on the frigate. The ship was crippled in orbit due to a fusion core accident. The frigate later crashed into the surface of the planet shortly after Samus defeats the Parasite Queen. Samus would later find the wreckage and have to traverse through it to reach the Phazon Mines.

The vessel makes an appearence in Super Smash Bros. Brawl as a stage, the stage is located in the reactor core with the Parasite Queen watching. The stage occasionally rotates 180 degrees.
