Editing The Gauntlet

|footer=Mario and Luigi battling [[Dark Star X]] in the Gauntlet from ''[[Mario & Luigi: Bowser's Inside Story]]'' (left) and ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]'' (right).

'''The Gauntlet''' is an area in the [[Challenge Node]] that appears in ''[[Mario & Luigi: Bowser's Inside Story]]'' and its [[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey|Nintendo 3DS version]]. It is where [[Mario]] and [[Luigi]] can face harder versions of seven bosses whom they have battled over the course of the game; the [[Emoglobin]] near the entrance explains that they mined the Bros.' memories to create stronger versions of bosses previously encountered. All of the boss rematches are denoted with the letter "X" (e.g. [[Durmite X]] for [[Durmite]]), and use faster and more powerful variants of attacks from their base movesets. A similar area called the [[Battle Ring]] appears in ''[[Mario & Luigi: Dream Team]]'' and ''[[Mario & Luigi: Paper Jam]]''.

The following Mario Bros. Bosses can be fought in The Gauntlet:
