Digimon World: Next Order
A Youkomon in Bony Resort asks if the knows, Boltmon, and WereGarurumon, as it had found an engraving stating it needed to defeat the trio to fulfil a prophecy. After learning that the Hero was friends with them Myotismon and WereGarurumon, Youkomon realises it was too late to defeat them, though still holds out hope about defeating Boltmon. After the Hero finds Boltmon, Boltmon turns to be a coward and tells the Hero to inform Youkomon that it had drowned in a lake, though Youkomon doesn't believe it. Boltmon then asks the Hero to ask Myotismon to come up with a plan so that it could avoid fighting Youkomon, which Myotismon agrees to do. Myotismon asks Youkomon to fight it as part of the prophecy, and then Myotismon uses its magic to make Boltmon appear as though it is actually Myotismon. Youkomon attacks "Myotismon", and when Boltmon tries to run away from conflict, Youkomon is accidentally defeated when it comes into contact with Boltmon's battle axe. Confused as to what was going in, Boltmon assumes it lost to the Youkomon, and then joins the City after being convinced by WereGarurumon and Myotismon. Youkomon however, aware of its defeat, states it will train until it is strong enough to defeat the trio, so it can fulfil the prophecy.
