Apollyon first appears in the episode Punch the Clock, where its ball form appears in a large container of liquid, as Philomena Dusk looks at it with a smile before the episode ends. Apollyon appeared again, in his ball form, in Backfire Brawl. Its monster form debuts in the episode Awesome vs AAAnimus Part II, where Philomena uses it to battle the Awesome Ones. Apollyon easily defeats Lupitheon, Vicerox, Gorthion, Artulean, and Cyndeous in one hit before being defeated by the evolved forms of Dragonoid, Trox, Howlkor, Pegatrix, and Hydorous.
