Fafnir

Fafnir is one of the Seven Great Dragon Kings, and Evil Dragons. He is the Golden Dragon known as the Panzer Dragon.

Appearance
He has the ability to shapeshift into a human form or a Dragon form. In his human form, Fafnir has the appearance of a tall man wearing a black trench coat with a mixture of silver and blond hairs as well as purple eyes.

In his true form, Fafnir resembles a majestic golden Dragon with a silver and purple aura surrounding him. Since he has black wings, Fafnir is a Western Dragon.

Personality
Unlike the other Evil Dragons, Fafnir appears to be calm and quiet as he usually leans on nearby walls when on standby, and is highly loyal to Siegfried. He also appears to put his objectives first as, despite his love for battles, he was willing to leave after seven minutes when he was only told to hold off Cythraul. He also seems to have a much greater amount of self-control since he backed down after Arthur refused to fight due to exhaustion.

Fafnir also has an extremely merciless side which is what earned him an infamous reputation as an Evil Dragon as shown when he ruthlessly brutalized Niðhoggr after the latter threaten to attacked Ophis and Maria who were in the Dimensional Gap, and then kill Siegfried and his siblings.

Despite all of this traits, he has a great deal of honorable and respectful nature of a true Dragon, even though an Evil Dragon just like Ladon, Apophis and Azi Dahaka since he also hates dirty and nasty tactics and tricks, as he states, during his intervention against Niðhöggr through the Siegfried, that he will relentlessly and ruthlessly beat him up until his consciousness fades, and all thats left is a pile of blood, organs and scales. Tannin also noted that out of all the Evil Dragons, he is the purest one despite being called the most evil out of all of them, because he lived for many centuries and Fafnir's eyes have seen many things including the vast changes in the history of the Human world which, in turn, have changed his views, and his also the reason he chose to form a pact with Siegfried.

History
Not much is known about Fafnir except that he was previously killed by the original Siegfried Sellzen of the Hero Clan who wielded the Demon Sword Gram but was later revived by the Norse Gods.

Fafnir is amongst the strongest of ancient Dragon Kings and Evil Dragons that lived in a space separate from that of the Vampyres, Demons and Seraphs. During the Great Mythology War, Jin, Siegfried, Maria, and Ophis ended up trapped inside of Limbo as all of them were trying to escape. Together, all four of them were able to fight off Fafnir and was asked by Siegfried if he would want to form a pact which Fafnir accepted. He also helped Jin and Siegfried fend off the Evil Dragon, Ladon and 20 clones of the dragon Grendel.
