Mario Circuit (SSB4)
The stage takes place on a set of platforms that move around the track, and will stop at certain parts of the track, similar to Mute City, Port Town Aero Dive, and the 3DS-exclusive Mario Kart stage Rainbow Road. Shy Guys drive around the track, which is a reoccurring theme in the Mario Kart stages. Because of the track's antigravity effect, the road will sometimes be above or to the side of the fighters. Unlike in Mario Galaxy, fighters are not affected by the unusual gravity. The track is able to meteor smash anyone under it while moving. Star KO's are normally banned on the stage, though Screen KO's can happen.
There are eight locations the platforms can stop at. The platforms will skip a random number of locations between each stop as they follow the track. In order around the track:
Ω forms and Battlefield form
In Super Smash Bros. for Wii U, the Ω form uses the same base platform as the regular form, but it can not be passed through from below. The platform also doesn't stop at any locations, and the track doesn't interact with the stage.
In Super Smash Bros. Ultimate, the Ω form and Battlefield form are similar to the Ω form in SSB4; however, the main platform is resized and reshaped to match Final Destination. The three soft platforms of the Battlefield form are metallic and are unique to this form.
Mario Circuit is the name of a track that appears in every Mario Kart game since Super Mario Kart. This stage is an accurate recreation of Mario Circuit in Mario Kart 8 and Mario Kart 8 Deluxe, which is a prime example of the twisting, F-Zero-esque course layouts made possible by the game's new anti-gravity mechanic. The design references a Möbius Strip, which is used in experiments with magnets, including magnetic levitation, which ties back back to the anti-gravity mechanic.
Mario Kart DS is the first game that allowed Shy Guys as playable characters, but only through DS Download Play. If friends wanted to play the game together, but somebody didn't have the game, they could still connect together through DS Download Play. It wasn't until Mario Kart 7 that Shy Guys were playable through normal means. In this stage, the karts are driven by Shy Guys, and the karts they drive on are the Standard Karts from that game.
The movement of this stage causes stage hazards due to parts of the road dealing damage to fighters. Some of the landing positions also have strange layouts that make competitive fighting difficult; as such, this stage is usually banned in competitive play.
