Fafnir

Fafnir is a demon in the series.

History
Fafnir was the son of the dwarf king Hreidmar, and the brother of Regin and Ótr in Norse mythology.

After Ótr was killed by Loki, Hreidmar received the cursed gold of the dwarf Andvari's as repayment for the loss of his son. Fafnir and Regin then killed their father to get the gold, but Fafnir decided he wanted it all, becoming a dragon (symbol of greed). Regin then sent his foster-son, Sigurd, to kill the dragon. Sigurd succeeded by digging a pit under the trail Fáfnir used to walk to a stream and plunging his sword Gram into his heart as he walked past. Regin, however, corrupted by the curse on Andvari's gold, planned to kill Sigurd to take the treasure for himself, but Sigurd, having eaten part of Fafnir's cooked heart, was warned by birds of Regin's attack and ended up killing him.

Shin Megami Tensei IMAGINE
Fafnir was implemented during the 2015 Halloween event and his plug-in could be acquired during this time. He is fused in a special triple fusion of Titan, Dwarf and Vouivre.

Shin Megami Tensei: Strange Journey
Fafnir appears as a random encounter enemy in Sector Horologium. He mostly appears in the basement floors and especially in the dark areas. His "mechanical dragon" appearance in this game is a key point in an EX Mission, The mecha-dragon's secret, where a part of him can be requested - either screws, scales or circuits - which will be made into a piece of equipment.

Shin Megami Tensei IV Apocalypse
Fafnir can teach Nanashi the Poison Breath, Earthquake and War Cry skills through his Demon Whisper. He benefits from learning Physical, ailment and support skills.

Shin Megami Tensei V
Fafnir is a member of the Nordic branch of Bethel and can be found as a common enemy in Da'at: Taito's Nordic section. He is one of the demons required to fuse Vasuki.

Devil Summoner: Soul Hackers
A Fafnir is necessary in order to fuse Zeed into the General Hagen.

Devil Survivor 2 Record Breaker
Fafnir appears as one of the downloadable demons in the game. It can only be fused using Hagen and Culebre.

Persona: Tsumi to Batsu
A Fafnir appears on chapter 3, with its Soul Hackers design. Narui attempts to negotiate with it, but it gets angry and injures several civilians with its Poison Breath, before being defeated by Narui and Kazumi's Fusion Spell

Persona 5 Royal
Fafnir is the eleventh Persona of the Hermit Arcana, and can either be found during the Third Semester Arc within Maruki's Palace or otherwise available to be fused after 1/12. They can be found past the warehouse and stop appearing after the Counseling Room. As a Shadow, it is known as "Evil Voracious Dragon." Due to its unique set of resistances and lack of weaknesses, it can only be knocked down via Technical damage or Down Shot, and as it is a Savage Shadow it must be at low health before it can be negotiated with. A Fafnir also stands guard in front of the Blue Sorrow Will Seed.

Fafnir's negotiation and drop yield consists of only Sooty Scale Armor, which can be washed into Old Scale Scarf and Dragon Scale Scarf, the latter of which is Morgana's strongest armor. Dragon Scale Scarf greatly reduces damage taken from Physical attacks.

When itemized via Electric Chair execution, Fafnir offers the Spiral Reactor Ring accessory, which allows whoever wears it the ability to cast Mafreidyne, though during a fusion alarm, Fafnir instead offers the Fire Dragon Horn accessory, which instead allows the use of Atomic Flare.

Trivia

 * Prior to Devil Summoner: Soul Hackers, Fafnir's design was a palette swap of Pendragon. In the Devil Summoner series, it gone through a distinct redesign and has retained this appearance in subsequent games.
