One of the Olympos XII and Jupitermon's partner. They take their place on the battlefield as Jupitermon's loving protector, prepared to exterminate anyone who would oppose Jupitermon's will. Perhaps it is because of Junomon's deep fondness for Jupitermon and its affectionate nature, but it has a good understanding of all of Jupitermon habits.
Junomon's special moves include Needle Hive, where it stabs opponents repeatedly with the katars on its arms, and Graceful Lance, in which its lance automatically attacks surrounding enemies using its own will. Junomon can also summon Love Basket to augment Jupitermon's power, a move that befits its position as Jupitermon's partner.
