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 that grow on his back unlike the usual Western Dragon, 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 pervertness, he is shown to be exceptionally faithful to every masters and contractors that he serve, as he faithfully always lending his powers from all of Azazel's fights, and protecting Asia while risking his life on the line, and didn't stand aside despite his grave injuries, while giving a smile.


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.

In Volume 4, Azazel reveals that he made a pact with Fafnir to be sealed inside his Artificial Sacred Gear, the "Down Fall Dragon Spear".

The Heroic Oppai DragonEdit

In Volume 10, Ddraig privately contacted Azazel through Fafnir's jewel to ask him to search for a Dragon Counsellor as he has been crying unconsciously.

The Legend of Oppai Dragon and his Lively CompanionsEdit

It was revealed in Volume 14 that he had made a pact with Asia after being freed from his contract with Azazel. He helped awaken Ddraig from his slumber with the help of Vritra during the battle between Khaos Brigade and the members of the Occult Research Club and the Student Council.

In Volume 15, he is shown to be in the indoor pool of the Hyoudou Residence while having both Ophis and Rassei seated on his head. After standing in the pool next to Asia he commented on wanting to drink the pool water she had been in after he saw her in her swimsuit.

In Volume 16, Fafnir participated in the battle against Crom Cruach but demanded Asia's school swimsuit first as payment for their pact. He provided the replica of the magical bullet, Tathlum, that Azazel gave to him as payment for their previous pact to be used against Crom Cruach.

Fafnir, together with Vritra, was asked by Ddraig and Albion in Volume 17 for help to convince the past possessors of Divine Dividing into helping them. It was later revealed that they were able to convince the past possessors and it was Fafnir who greatly contributed to the cause by introducing the wonders of panties to the past possessors.

After being summoned by Asia to help them in the battle against the mass-produced Evil Dragon, Fafnir appeared wearing a chef's hat with equipment and props used in a cooking show. He then cooked an original recipe of his, "Diavola Asia-tan Fried Panty" and was able to captivate the hearts of the mass-produced Evil Dragons with some of them even crying.

In Volume 18, Fafnir was summoned by Asia to help defend heaven. He took a brutal beating from Rizevim Livan Lucifer but went into Outrage mode after seeing Rizevim slap Asia, knocking Lilith aside and biting one of Rizevim's arms. Issei then took over the fight. Afterward, Fafnir lost consciousness, going into a deep hibernation of sorts until his injuries had healed.

In Volume 20, it was revealed that after his fight with Rizevim in Volume 18, Fafnir converted his spirit into a curse that allowed him to endlessly attack the Super Devil in his dreams, chasing Rizevim relentlessly and killing him again and again. Then, just before Vali was about to deliver the killing strike, Fafnir appeared and bit Rizevim in half with his mouth, killing him.

In Volume 23, Fafnir was a guest appearance for the announcer for the Rating Game match between Issei's team and Dulio's team, throughout most of which he made perverted comments regarding Asia and her panties.

Fafnir reappeared in True Volume 2, assisting Asia and her team match against Rias and her team, by letting the Church Trio ride on him through the gate and was confronted by Crom Cruach. Fafnir entered his Outrage mode when he revealed he was ordered by Rias to take out Asia and he plans to slaughter her, with Fafnir accepting his challenge to protect Asia from him. They began exchange punches that the houses around them were destroyed and tried to attack Crom with his claws, fangs, and all other body parts, but they were deflected and Fafnir was blown away by Crom’s strength. He asked Asia to take out the panties so he can summon the mini Fafnirs from his mouth and latched onto Crom’s body, biting and scratching him, while those that latched onto his back punched him. The mini Fafnirs were blown when Crom unleashed his aura and fired powerful aura bullets, which causes Fafnir to shield Asia from the explosion and damaging him. When Asia was healing him, Fafnir summon his last strength to get up and bite Crom’s arm, which excites Crom that someone managed to break his arm. Fafnir was later engulfed by Crom’s flames and he apologized to Asia as he disappeared from the field.
