This is about the Mario Circuit in Super Smash Bros. for Wii U. For the Mario Circuit in Super Smash Bros. Brawl, see Mario Circuit (Brawl).
Mario Circuit (マリオサーキット, Mario Circuit) is a stage based on the course of the same name from Mario Kart 8 in Super Smash Bros. for Wii U.
The stage takes place on a set of platforms that move around the track, and will stop 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.
