Apollyon (アポリオン, Aporion?) is a skeleton warrior-like Bakugan Battle Planet Bakugan that was first seen at Emerald City Comic Con 2019. Its shield can be seen in the Action Card Bone Defense. In the anime, it is owned by Philomena Dusk.
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. Its monster form debuts in the episode Awesome vs. AAAnimus, Part 2, 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.
While Apollyon has not yet seen a physical release as a standalone toy, it is a component of the fusion bakugan Cloptor x Apollyon from Armored Alliance.
- Apollyon is the first character-owned Bakugan to have over 600 B-Power.
