Mercurymon: Spirit Evolution tree

Names link to DigimonWiki/Fandom (Fandom community, CC BY-SA unless noted otherwise); artwork © Bandai, via the official Reference Book. Card labels show the Spirit tier; edge colors show the Spirit trigger. Frontier has no partner Digimon: Cherubimon gave life to the H Spirit of Steel as Mercurymon, who also holds the B Spirit to become Sakkakumon; AncientWisemon is the Warrior of Steel who left those Spirits (lore links, not steps). No Fusion of the Steel Spirits is recorded. In episode 28 Mercurymon takes in Seraphimon's data to become ShadowSeraphimon, which is not a Spirit Evolution. In episode 35 Koji unifies the Spirits of Steel with four other Warriors' Spirits into MagnaGarurumon (see panel). In episodes 48 to 50 Takuya and Koji, and in the last one all five children, merge with the ten Warriors' Spirits into Susanoomon; the tree draws it from MagnaGarurumon and Takuya's EmperorGreymon (see panel), which hold those Spirits, as the Hybrid-Digivolving figures do. Sakkakumon, AncientMermaidmon and Susanoomon are DigimonWiki's names for the official Sephirothmon, AncientMermaimon and Susanomon.
