Brionacmon is a Dragon Digimon whose scales on his serpentine body are made of Blue Chrome-Digizoid. He bears a pair of leathery wings which marked by the Digital Hazard symbol. Brionacmon is a creature that thirsts for the blood of all Digimon deemed impure in his eyes, though his sense of judgment is to question, thus placing him as a possible threat to all.
- Razor Zephyr: Beats his wings together to produce a powerful gust that slashes anything within distance.
- Berserk Hazard: The Digital Hazard symbols on his wings begin to glow until they are unleashed as devastating energy blasts.
- In Celtic mythology, Brionac was the magical living spear of the god/hero Lugh. It was said that its thirst for blood was so great that only by steeping its head in a sleeping-draught of pounded fresh poppy seeds could it be kept at rest.
