Figure-8 Circuit (stage)

Figure-8 Circuit (formerly known as Mario Circuit) is a stage in Super Smash Bros. Brawl, and reappears in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate. The stage takes place on a 8-figure intersection of a course resembling the Figure-8 Circuit from Mario Kart DS. In Ultimate, the stage was renamed to Figure-8 Circuit to be distinguished from the for Wii U stage of the same name.

The stage is set up with two levels; the bottom level, which is a flat surface across the race course, and the upper level, which takes place on a few platforms of the race course. On occasion, go-karts driven by Shy Guys (the ones from DS Download Play of Mario Kart DS) race along the back or sides of the stage, crashing into characters, damaging them greatly. When they come in from the back, they hit the bottom level, and when coming from the left, they hit the upper level. Players can keep track of where the Shy Guys are from the screen in the back of the stage. However, like in Mute City and Onett from Super Smash Bros. Melee, the Shy Guys can be knocked aside with items, such as the Home-Run Bat. In the background of the stage, there is a big screen which shows the racers' positions on the track (by which fighters can guide themselves as to where to stay, if on the upper or the lower section). The Ω form of the stage takes place in front of the normal stage on a raised platform. Shy Guys can be seen but do not interfere with the fighters.

In 8-Player Smash versions of the stage in Super Smash Bros. for Wii U, Shy Guy racers do not appear.

My Music
The My Music songs present in Super Smash Bros. Brawl all return in Super Smash Bros. for Wii U for this stage, however the requirements to unlock them listed below only apply to the former, as all songs in the latter are available from the start.

Trivia

 * In the trailer that originally revealed this stage, the Shy Guys were all driving white karts and the screen in the background was blank. Since then, the radar has been added to the screen and the eight Shy Guys participating are now paired, with the kart colors being either green, blue, orange, or white.
 * Players can affect the way the race turns out. If the player attacks or flings themselves in front of anyone except the Shy Guy in the lead, the leading Shy Guy could get so far ahead, that as it flies over the stage, the others are coming below it.
 * In Mario Kart DS, on the Touch Screen map, the logo of a particular cup floats about underneath the map and names (for example, multiple mushrooms float around for the Mushroom Cup, stars for Star Cup, and so on). In Super Smash Bros. Brawl, the symbol of the Super Smash Bros. series is displayed instead.
 * In Super Smash Bros. Brawl, the game logo used to identify the origin for this stage is the older Mario Kart series logo, used up until Mario Kart Arcade GP 2. In Super Smash Bros. for Wii U, the logo is the current version used from Mario Kart DS onward.
