Agumon: evolution tree

Names link to DigimonWiki/Fandom (Fandom community, CC BY-SA unless noted otherwise); artwork © Bandai, via the official Reference Book and Wikimon. Card labels show Level (+ X); edge colors show the digivolution trigger. AncientGreymon is an ancestral (lore) relation, not a direct path. Kimeramon is a composite of parts from various Digimon, so it has no incoming arrow. The Virus forms are drawn as one chain from BlackAgumon because each profile makes its form the Virus counterpart of the Vaccine one, not because a source shows them digivolving; the BlackWarGreymon of Adventure 02 was built by Arukenimon from 100 Control Spires. Omnimon Zwart and Omnimon Alter-B are temporary forms caused by Black Digitron, drawn as Mode Changes. Omnimon Merciful Mode is a collective composition (Adventure tri.): Omnimon plus Phoenixmon, HerculesKabuterimon, Rosemon, Vikemon, Seraphimon and Magnadramon. Omnimon Alter-S, Alter-B and Zwart Defeat keep their official names here (Omegamon on DigimonWiki).
