The Gauntlet is an optional inside Bowser that is located in the Challenge Node. The player fights several bosses, who are stronger versions of bosses fought in the main story. Defeating them all unlocks the final battle class, with a secret boss at the end. Completing the Challenger's Road unlocks the TRUE Gauntlet, consisting of a series of fights against the Challenger's Road bosses.
