Anime and Manga
- Yolei's "Mimi fantasy," in which Mimi suddenly has blue eyes so that she looks more like Utena.
- There is a quick blink-and-you-miss-it shout out in episode 15; when ShogunGekomon sees the dark tower erected, he cries out "GeGeGe no Ge!"
- Diablomon Strikes Back has Armageddemon, whose appearance is reminiscent of an Angel. Furthermore, when Omegamon is severely wounded in the battle, he is left standing up with his arms having fallen off in a pose that echoes Unit 02 after being defeated by Zeruel.
Literature
- The Dark Ocean and Dagomon, to the Cthulhu Mythos (the episode was written by Chiaki Konaka, who actually has written Cthulhu Mythos stories).
- A cool reference to catch after watching Interstellar: during the final episode, as Malomyotismon covers both worlds in darkness, he boasts, "The dying of the light, and no one to rage against it!" This is a reference to Dylan Thomas's poem, "Do not go gentle into that good night."
- The Drama CD Natsu e no Tobira refers to a Robert A. Heinlein story called The Door into Summer, and derives its own title from the Japanese translation of the novel's.
Film
- Ebidramon seems to be a reference to Godzilla's Ebirah, with both being large crustacean-like sea creatures.
- The dub title of Revenge of Diaboromon is a Star Wars reference, paralleling Diablomon Strikes Back. Revenge of the Sith had just been released a few months prior.
Other
- When facing a Dark Ring-controlled Ninjamon, Miyako in the Japanese dub nonchalantly compliments him that compared to Shurimon, his skill with the shuriken is second-best in the Digital World.
