I'd love to see your take on a naga or snake girl, with a full snake tail and an unhingeable jaw

I've shared a few types of Naga before, including the water naga, guardian naga, and even the Tsuchinoko Naga, so I thought I'd display a Fire Naga today.
Also known as a Flametongue Naga, a Flame Naga, Inferno Naga, or as they're best known, Agninaga.
Agninaga are like other Naga, and can be created in many ways. Sometimes through the transformation of a serpent, or other times through transformation of a human. Regardless they are imbued with a divine spark of Eden, and ignited within them is the world furnace, an endless fire that roils out of control for eternity deep within their gullet. Serpents and priestesses who inherit this spark consume all around them in their endless hunger, and as they do, they cultivate the furnace and they begin to transform. Their bodies grow larger, and their hair begins to wisp away into cinder as the air around them heats and burns those that stand too close. Offerings brought to them ignite and are burned to cinder as they consume them, and in time they fully transform into an Angninaga. There is even a curse that can transform a creature into an Agninaga forever.
Agninaga can of course unleash a destructive flame breath, however the fire they release consumes not only materials it touches and burns them away, but it also burns magic and as such can destroy even magic items or creatures immune to fire as it burns away the creature's immunities granted by magic. The flames created from the world furnace are nearly impossible to extinguish if there is magic in the area, as magic will fuel the fire to burn even in water or a vacuum, and as such they are the bane of arcane spellcasters, as some immediately detonate like powder kegs from the spark of fire from the Agnigaga. It's mane of fire that trails down it's back can equally be as destructive, though it can choose what it's mane does and does not burn. Even it's blood can ignite flames, working similarly to gasoline or lighter fluid, and spellcasters occasionally utilize said blood in spellcasting to improve their fire spells capability.
Not only is it deadly for it's flames, however it can inflict a terrible bite on it's foes that does the same, it's mythical venom igniting the blood of it's foes and burning away all magic potential. Spellcasters whom have survived battles against Agninaga have been left unable to ever perform magic again and in chronic pain due to their actual magic ability, and even portions of their soul can be burned away by this attack, leaving them vacant and soulless husks of their former selves.
Many learn to wield weapons, or retain knowledge of their weapon wielding from their life as a human, and some know how to harness the flames of their world serpent to cast destructive fire spells, imbuing the spells with the flames of the world furnace to make them unstoppable.
Incredibly powerful Agninaga may grow multiple sets of arms, up to possessing 20 pairs of arms, and may even sprout multiple heads.
Worshippers of the Serpent God Yig, or of his consort Jormungandr, may be cursed with this form as a gift or as punishment by the serpentfolk followers of the deities.
Agninaga are of very few words, often times simply commanding creatures to be gone from their territory as they often times are used to protect treasures or prevent entry to divine gates. Some can take a human form, and those who can often times also work as hunters, tracking down enemies of their deity and killing them, devouring them and casting them into the world furnace to work as fuel to empower them. During the Godswar, the Flame god Saroth created Agninaga with the aid of Ifrit to protect their divine locations and to face off against the Tojanaga created by Degra.
