–Fafnir while protecting Asia, Volume 14, Life.4

Fafnir is one of the Five Great Dragon Kings. He is the Golden Dragon known as the Gigantis Dragon.


Fafnir is a golden Western Dragon that is more than 10 meters tall, who lacks a pair of wings on his back, which are possessed by most Western Dragons, and has a horn on the tip of his nose. In his first appearance, Fafnir had a pair of Asia's panties on his horn. In Outrage mode, Fafnir is able to manifest a pair of wings.


Little is known of Fafnir's personality due to him being sealed in Azazel's Artificial Sacred Gear, as well as the fact that there are very few instances of him being described. He's not as proud as other dragons. As mentioned by Sona, Fafnir has a tendency to collect treasures throughout the world.

In his first appearance, Fafnir is revealed to be a perverted Dragon with a fetish for panties, sniffing them and referring to them as "treasures". According to Ddraig and Albion, Fafnir wasn't as perverted in the past as he is right now. However despite his perverseness, he is shown to be exceptionally faithful to those he serves, as he frequently lends his powers to Azazel, and protects Asia while risking his own life in the process, and didn't stand aside despite his grave injuries.


Not much is known about Fafnir except that he was previously killed by the original Siegfried who wielded the Demon Sword Gram but was later revived by the Norse Gods. Azazel also believes that the influence of Odin in his revival is the reason for the dragon king's pervertness. Prior to the series, he made a contract with Azazel to aide him in his Sacred Gear research by allowing himself to be sealed inside Azazel's Artificial Sacred Gear.
