Beetlemon: 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: J.P. Spirit-Evolves into these forms and has no Child form; AncientBeetlemon is the Warrior of Thunder whose Spirits J.P. wields (lore links, not steps). RhinoKabuterimon, the Fusion of the two Thunder Spirits, comes from the D-Tector V-pet, outside the Frontier anime. In episode 35 Koji unifies the Spirits of Thunder 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. Susanoomon and AncientMermaidmon are DigimonWiki's names for the official Susanomon and AncientMermaimon.
