Lopmon is a brown-furred Beast-species Digimon at the Rookie level, marked by distinctive pink patterns across its collarbone, paws, and ear tips. Three horns protrude from its forehead, contrasting with its twin Terriermon's single horn, and it possesses notably long, frayed ears. Classified with a Data attribute, its beast-like physiology exists within a largely mysterious ecosystem. Personality-wise, Lopmon displays a reserved and compassionate nature, differing from Terriermon's robust demeanor. It shows deep concern for other Digimon and their environments, actively aiding those displaced by habitat destruction. This gentleness coexists with potent combat abilities, utilizing ear-based techniques like Petit Twister—generating small tornadoes by whipping its ears—and energy attacks such as Blazing Ice, firing supercooled air projectiles. Within *Digimon Adventure:*, Lopmon's background identifies it as the reincarnated form of Cherubimon, a Holy Digimon veteran of the ancient war against Millenniummon's Army of Darkness. After the conflict, it regressed to Rookie form and lost its memories. Witnessing MetalGreymon evolve into WarGreymon, a warrior it fought alongside centuries prior, triggered the return of its memories. This restoration enabled Lopmon to warn Tai Kamiya and Sora Takenouchi about Millenniummon's resurgence and the looming threat to both worlds. Lopmon actively supports the DigiDestined, using residual holy powers to resurrect Komondomon for transportation. Later, it psychically communicates with Patamon after he loses his ability to evolve into Angemon, guiding him toward an alternative evolutionary path as the "light of hope"; this guidance culminates in Patamon achieving Pegasmon to defeat Cerberumon and Fangmon. Following Millenniummon's defeat, Lopmon journeys with Digimon displaced by the Dark Army's attacks—including two Peckmon, Falcomon, Spadamon, and Baby-level Digimon—aboard a grey Komondomon. During the "Great Catastrophe" caused by Negamon, Lopmon communicates with the DigiDestined via digital screens alongside Xiaomon, explaining the phenomenon and expressing faith in their ability to create miracles beyond their victory over Millenniummon. After Negamon's defeat, Lopmon resides atop a Jyureimon tree accompanied by the grey Komondomon and groups of Budmon and Woodmon. It recounts the origin of the human world to these Digimon and participates in Leomon's reflections on the DigiDestined's role as protectors and friends, underscoring its transition from ancient warrior to a spiritual guide fostering inter-world understanding. Its evolutionary line progresses from Lopmon (Rookie) to Turuiemon (Champion), then to Andiramon (Perfect/Ultimate) as one of the Deva, and finally to Cherubimon (Ultimate/Mega) in its Virtue form, reflecting its restored holy heritage.
