The main body of Pyrosphere is a fairly long platform with a metallic surface mounted on top of a tall metal shaft extending down below the surface of the lava. Above it floats four metallic platforms sporting green glowing strips wrapped around them. The lava appears pouring in the background, but does not affect the playing area.

[[Ridley]] will appear periodically to attack players and destroy floating platforms. He can increase his strength from absorbing energy from the tanks under the ledges, which blackens his skin in the process. If he receives enough damage, he will become an ally to the last attacker. Defeating him counts as a point in [[Time]]d matches.

During the fight at the Geothermal Power Plant against Ridley, he could harden his skin to render himself invulnerable to Samus' Plasma Beam, signified by his darkened skin. In ''SSB4'', he absorbs the energy from the vats on either side of the stage to further augment his strength. The result is erroneously stated as a transformation into [[Meta Ridley]] in the English translation of the [[Nintendo Direct#Super Smash Bros. for Wii U: 50-Fact Extravaganza (October 23, 2014)|50-Fact Extravaganza]]; the Japanese version calls it {{ja|黒リドリー|Kuro Ridorī}} instead, which is more accurately translated as ''Black Ridley'' and does not reference the ''Metroid Prime'' series.

*The specifics of Ridley's role on Pyrosphere was withheld from [[Miiverse]] over a year after its announcement on August 20, 2013, when [[Masahiro Sakurai]] [https://miiverse.nintendo.net/posts/AYMHAAABAABnUYnWb9pUTQ revealed] the stage with a caption stating "An enemy from Samus's past may appear at any second…" On the April 8, 2014 [[Nintendo Direct]], Sakurai showed a clip of Pikachu being chased by Ridley on the stage - although only his shadow, wings, and tail could be seen - implying that he was set to appear on the stage. Ridley was eventually shown and his role as a stage hazard was ultimately detailed in the October 2014 {{forwiiu}} 50-Fact Extravaganza.

*Pyrosphere is one of five stages from ''Super Smash Bros for Wii U'' not to return in ''Ultimate'', the others being [[Orbital Gate Assault]], [[Woolly World]], [[Jungle Hijinxs]] and [[Miiverse]]. In Pyrosphere's case, it is most likely due to {{SSBU|Ridley}} being a playable character, although it should be noted that the Ridley in ''Other M'' is a genetic clone of the playable  Ridley.

*Pyrosphere is the only new stage in ''Wii U'' where the most likely track by default is an older remix rather than a new remix or a direct port.
