Lore notes
the stories behind the unusual arrowsAngemon's Sacrifice
The last partner to reach Champion in Adventure and the anime's first partner death: Angemon spent all his power to defeat Devimon, reverting to a Digi-Egg and restarting the cycle from Poyomon.
Every Devimon Is a Fallen Angemon
Devimon's official profile says it was an Angemon that fell into the Dark Area, with the Mark of Evil on its chest as proof. The red Angemon arrow also retells the corruption arc of the 2020 reboot.
Tsukaimon, the Familiar
Named after the tsukaima, the occult familiar spirit: despite looking like Patamon it serves Devimon, attacking by whispering slander (Bad Message).
Daemon, the Fallen Seraphimon
Seraphimon's official profile states that Daemon is said to have originally been a Seraphimon that fell to the Dark Area after rebelling against the embodiment of good.
Daemon (Mantled)
Under this crimson mantle Daemon led the Daemon Corps in Adventure 02; too powerful to destroy, it was only banished into the Dark Ocean. A look, not an evolution.
ShadowSeraphimon
The Frontier dub name for BlackSeraphimon: officially a form of Seraphimon engulfed by its concealed inner resentment. In the anime it is Mercurymon fused with Seraphimon's stolen data.
BlackSeraphimon
The Digimon World 3 boss shares its Japanese name with ShadowSeraphimon but is treated as a separate entity: an unobtainable jet-black recolor of Seraphimon.
One Absorption from the Top
Daemon (Ultra) exists only in the V-Tamer 01 manga, where Daemon absorbs Arkadimon's data and surpasses the Mega level.
