Flash Tracer

Flash Tracer (フラッシュトレーサー) is a mini-game that appears in Kingdom Hearts III. There are two versions of the mini-game, simply labelled Course A (Aコース) and Course B (B Kōsu). Course A is first played after arriving at Hiro's Garage, and can be replayed at any time after San Fransokyo is cleared by speaking to Fred. Course B can be played by speaking to Go Go Tomago after San Fransokyo is cleared.

Story
After Sora, Donald, and Goofy defeat the Heartless on the Golden Gate Bridge, the members of Big Hero 6 rendezvous in Hiro's Garage, where they are introduced to the off-worlders. Once Sora has explained the nature of Heartless, the team comes to the conclusion that they are ill-prepared to fight them, and Fred proposes that they undergo training, or shugyo. Hiro then bestows Sora with an AR Device and explains its functions before preparing the Flash Tracer setup. Sora and Big Hero 6 then go through Course A, with Sora's abilities inspiring the members of Big Hero 6 to vary their skill sets and request Hiro to upgrade their devices.

Mechanics
Flash Tracer consists of an obstacle course of colored rings that Sora can pass through, as well as holographic Heartless to fight, en route to a star-shaped end goal; Course B also introduces colored targets that Sora can shoot. Defeating Heartless and passing through rings will score points. Travel throughout the City is more limited during Flash Tracer, with virtual boundaries that are not present during normal gameplay. Both courses include areas where Rail Slide must be used, with multiple rails that Sora may jump between using a Situation Command. Course B also begins with the use of Baymax's Interceptor Wing.
