Curiosities
- Parasite Cage and Vexen are the only bosses not to appear in the Room of Truth on each floor. These appear in The Room of Guides and the Room of Beginnings respectively.
- False Riku is the only boss that gives Item Cards, except in Riku's story, where he doesn't give any bonuses.
- In Reverse / Rebirth mode, bosses always appear in the Beginning Room. Except for Maleficent.
- Although Axel seems like a Boss on the final floor of Castle Oblivion (in Sora's story), he is considered more like a Deputy Boss.
