Giant X Bosses

 * Robo-Drilldigger X
 * Mount Pajamaja X
 * Earthwake X
 * Zeekeeper X
 * Giant Bowser X
 * Giant Medley: All previous giant bosses.

Trivia

 * Bowser Jr. is the only boss without X in his name.
 * Grobot X is a required boss, as beating him after the second trip to Dream's Deep awards the bros. the Zeekeeper's Feathers, which are required to make the Ultibed.
 * Kamek is the only major antagonist in the game who is not fought in the Battle Ring.
 * Antasma is the only major antagonist fought in the Battle Ring to have an alternate color scheme, as Bowser and the Elite Trio retain their original color scheme.
