Elderlymon

Biodata

Power Progression

Background / History

Elderlymon is regarded as File Island’s oldest Digimon. Some inhabitants believe he is as old as the island itself, though his exact age is not established. His standing is so high that he and Elecmon are described as the island’s true rulers despite their relatively low evolution levels 12 13.

He helped other Digimon excavate Infinite Mountain’s Mountain Ring Road during the island’s sacred heyday. At that time, File Island contained the Digimon World’s only Village of Beginnings, and many In-Training Digimon were sent to the mountain’s summit to pass through its Gate to their destinations 13.

As Mastermon, he guarded the Gate day and night and learned about the countless worlds it connected. The loss of the Gate during the Darkness Invasion left him despondent. Believing he could no longer contribute to future battles, he donated its evolution-granting power to Digivice research, becoming Elderlymon 13 31 47.

He also preserved knowledge of the Metal Empire’s failed attempt to transform File Island into a Sea Ark using the lingering power of fallen Mega Digimon. The attempt shattered the island and killed many Digimon. When Infinite Mountain subsequently began corrupting its inhabitants with Dark Power, the island’s Digimon sealed it off 13.

Appearance

Elderlymon resembles a kindly, frail old man, while Mastermon appears as a handsome, robust middle-aged man without his former sickliness 29 30 31 41.

• Elderlymon: Wrinkled forehead, an elderly but strong voice, and a cane used for support and combat 16 31 49.
• Mastermon: A powerful physique described as potentially more robust than Leomon’s 31.
• Aura: Elderlymon gives off no intimidating aura despite his strength. After his restoration, Mastermon deliberately releases his aura so Zheng Fan can recognize him 13 42.

Personality

Elderlymon is protective but stern. He sharply reprimands Leomon for visiting Infinite Mountain and initially refuses to tolerate further attempts to explore it. His approachable appearance nevertheless makes him someone Mimi readily turns to for help 13 30.

He is willing to reconsider his judgments. Zheng Fan’s explanation of the mountain’s possible consciousness persuades him to investigate personally. Although he cannot put Zheng Fan’s spirit-fighting techniques into practice, he discusses them openly and offers insights of his own 14.

His concern for others overrides his safety: he intercepts a potentially fatal attack aimed at Mimi. He also exercises restraint with his support powers, refusing further use on humans after noticing adverse effects rather than granting Mimi’s repeated requests 30 31.

Restoring Mastermon brings out a more exuberant and proud side. He celebrates the return of his power, but later emphasizes that he has reclaimed an old ability rather than gained an entirely new one 31 42.
