"You think me afraid of death? Fool! It is death itself that must learn to fear me, Bahamut, the most powerful being in the universe!!" ~ Tyrannus DracoRex
Bahamut was was once a valuable ally to the Warriors of Light, but he was only fighting with them to acquire godhood so he can end the timeless struggle between light and darkness on his own terms. When he became an Astral, Bahamut was immediately corrupted into the Tyrannus DracoRex, and is retroactively the ultimate (if not overarching) antagonist of the Final Fantasy series as a whole.
Bahamut had taken on many forms throughout his existence, but the context of this page strongly accounts his physical appearance in Final Fantasy XV and it's expanded media; a giant winged humanoid with a helmet styled like a dragon's head, and a more grandiose semblance of Kain Highwind's appearance in Final Fantasy IV. His real face, however, is a disgusting, gruesomely mangled perversion of Somnus Lucis Caelum and/or Noctis' face with reptilian eyes.
Even before his transformation into arguably the most evil and corrupt deity in existence, Bahamut was an amoral, headstrong, arrogant, judgmental, ruthless, power-hungry dragon who rationalizes his thirst for battle and reckless destruction of lesser life-forms under his unflinching belief that sacrifice is, and always will be always necessary for victory and progress, and valued his duty above other lives and even his kin and allies. He sees himself as above the common conventions of good and evil and believes the ends justify the means, reacting in an abnormally violent or harsh manner to any moral backlash against his ways, stubbornly dismissing any alternate, more mutually acceptable solutions to any problem he is faced with, and at times even killing those who so much as rebuke him in the slightest. Bahamut also sees himself as the single absolute good of all existence, that the fate of the entire universe depends strictly on his self preservation and self-interest, which is why he wanted the Warriors of Light to become so overly dependent on his awesome power.
"He is now a malicious, sanctimonious, omnipotent warlord, wearing the face of a benevolent ruler, sowing much discord, bloodshed, destruction, sorrow, and death, all under the wretched lie that he is a wise God King making difficult decisions to save as many lives as realistically possible. But we know better now!" ~ Lightning
When he became the God of War by the events of Final Fantasy XV, Bahamut had finally lost all his moral light and became a truly evil, incredibly self righteous, and utterly cruel, tyrannical warlord who saw the destruction of an entire world as acceptable compared to an ever spreading pandemic of the daemons he so despised. As Tyrannus DracoRex, he had devolved from a harsh, morally ambiguous extremist into an egotistic, misanthropic, uncaring, deceitful, hubristic, vindictive, bloodthirsty, greedy, sadistic, lying, uncompromising, nihilistic, intimidating, ill-tempered, blame-shifting elitist and a complete hypocrite who enjoys toying with innocent life, torturing or persecuting his haters, committing war crimes, forcing people to violate their own principles, killing anyone who disagrees with his iniquitous personal narrative, and has no problem with sacrificing or betraying anyone to meet his goals and indefinitely maintain his undeserved godhood. He is also not above utilizing the darkness for his personal gain, despite his hatred of it, or cursing explicitly in the Hexatheon language to voice his angst-ridden contempt for anyone with the guts to rightly denounce him as the disgusting cosmic tyrant he has become.
The second time Bahamut intended to use TerraFlare on Eos, he especially desired to punish the other Gods and the people of Eos for disagreeing with his endeavors to make Noctis pay for the Gods' mistakes, contrary to Shiva likening his act to the work of a gardener; she believed in vain that Bahamut could realize his error as she had with her initial opinion on the humans of Eos. Even with his true nature exposed, Bahamut maintained his vile delusions to the bitter end, demonstrating his complete inability to realize the wickedness that slowly consumed him, or care what anyone else thinks or feels.
The only time Bahamut showed any remorse, or at least feigned it, was when he claimed the humans of Eos would be nothing without the gods, after his true face was exposed in the final battle. Whether the DracoRex was truly remorseful, or simply trying to better justify his profound greed and self-centeredness, Noctis still had to end Bahamut as punishment for the Great Betrayer's crimes, and so humanity can let go of the past and move on to a new age with no more incentive to take up arms against the remaining gods for the sins of just one. In fact, Somnus' newly found desire to make amends for his sins is an insight to Bahamut if he were truly sorry instead of hopelessly persistent in the hypocritical megalomania and realism that forever ruined his image and made millions of people believe the Hexatheon deserved to crumble under the weight of their leader's spiteful arrogance.
Bahamut was created eons ago to help protect the universe, but he was far more concerned with destroying evil to buy the fear and respect of mortals, and only protected them for his own pragmatic reasons. Some time after granting the original Warriors of Light additional power to defeat Chaos and the four fiends, Bahamut decided to destroy Palamecia to prevent the birth of Emperor Mateus and his consequential rise to power, or kill him and his royal family, depending on how prior to Final Fantasy II's events this attack happened. The summons Shiva, Ramuh, and Ifrit were morally against the idea, despite his unyielding insistence that it was the only way to save the world, and stopped Bahamut before he could completely destroy the nation, banishing him for his attempted genocide, thus explaining the true in-universe reason for their absence in Final Fantasy II. Bahamut was also weakened as further punishment for causing the deaths of thousands and made to answer the call of future Warriors of Light, starting with the Onion Knights, to learn humility, but secretly, he was furious at the rejection of his harsh ideology and methods of protecting the universe, and plotted to somehow become a god himself, so he can be free to satisfy his mass destructive urges without fear of admonishment or retribution from his contemporaries, without them ever escaping his cruel wrath; to do whatever unforgivable things he wanted and still be exalted on high as the ultimate force of "good". As time passed, Bahamut became increasingly addicted to slaughter, desensitized to injustice, and jealous of the Warriors of Light for their victories, believing them to have only succeeded in their goals because of his power.
At one point after becoming the ruler of Eos, Bahamut abused the Crystal's power to perpetuate a time-loop to continuously falsify his image and the Lucian Kings' history in the Cosmogony texts, and make the planet suffer again and again at the hands of Ardyn Izunia, it's people never knowing who the bigger-scale true offender is. But the Crystal eventually rebelled late in the fourteenth cycle, allowing for Noctis to finally learn about Bahamut's true nature during the fifteenth and final cycle. Despite his dwindling power, the Great Betrayer tried to keep the truth from being exposed but ultimately fails, leading to his demise at the hands of Noctis and Ardyn, who finally takes responsibility for doing to Noctis what Somnus did to Ardyn 2000 years ago. This also marked the end of the other Astral Gods, who repentantly accepted their deaths with dignity as the Crystal follows just after cleansing the Starscourge. Even with the timeloop broken and Noctis and Lunafreya being saved, the monstrous tyrant Bahamut's actions still had terrible consequences, such as creating a massively negative stigma around Crystals, Summoned Creatures and Gods, even if the Lucian Kings forgive them for their sins against humanity. There are those who still firmly and foolishly believe Bahamut did nothing wrong, despite the evidence of his crimes finally being apparent to the universe, and may even wish to assume his former seat of power, whether they wish to carry on his bloodstained legacy themselves or sate their own enormous ambitions and enforce their own warped doctrines. But there are also those who believe that even if Bahamut does somehow revive, as he had times before, he will already be stripped of his godly power, conferring a better chance to defeat him again, and he will be forbidden from returning to any world he had previously been summoned to.
Bahamut was, at one point, rumored to have been sighted in Ancient Egypt, tracking down Ardyn at a very late point in the 14th cycle. This rumor was later confirmed as true by an Abstergo employee-turned Assassin, and many sources correctly assume that Bahamut was there to stop Ardyn from potentially exposing the Dracorex's crimes to anyone, whatever the means either used to get to Egypt or what Ardyn's intent was at the moment in time.
Eventually, the other Warriors of Light discovered Bahamut's treachery and were so distraught and disgusted by his hypocrisy and the consequences thereof, that they vowed never to to use any kind of Bahamut-derived power or let another summoned monster manipulate anybody to rise to Bahamut's height of power again.
Powers and Abilities
Despite his awesome destructive power and his ability to exist in both the physical and spirit worlds at once, Bahamut is either not as all-knowing as he arrogantly claims, or he is deliberately blind to how his actions, like commanding one to sacrifice him/herself, can be seen as vile and heinous in the eyes of the subject's loved ones and the common man in general.
He must continuously siphon the (supposedly) limitless energies of Crystals to be able to warp reality to his liking, destroy entire planets, and maintain complete invulnerability. When the Crystal of Eos stopped letting him use it's power selfishly, Bahamut was forced to resort to harvesting the darkness he seeks to destroy as a power source for his TerraFlare, heedless of the hypocrisy this would entail. Even with both those options exhausted, Bahamut was still very formidable in battle, but not invulnerable to the combined might of the other Astral Gods and Noctis in the real world, much less the to Lucians and Ardyn using the very power Bahamut intended to use on Ardyn.
Also, he vehemently insisted that fear is the invincible ruling power, mainly due to how expertly he wielded the power to threaten others with violence and such. Bahamut's pride, which he thought contributed to his strength, was ironically also his greatest weakness, and it finally let to his destruction and that of the fraudulent myths he created around himself.
Tyrannus DracoRex's leitmotif of the same name is remixed from the final boss theme of Blue Dragon, by Nobuo Uematsu.
Another associated theme is "I AM KAISER", a variant of "The Gate of The Hell" by JAM Project.

Etymology and Symbolism
Tyrannus is latin for "tyrant", and DracoRex means "dragon king" in latin. This title means "Tyrant Dragon King" in latin, an appropriate description of the vile terror Bahamut had become, even calling the Tyrannosaurus Rex and it's pop-cultural connotations with villainy to mind. His title of "Great Betrayer" in latin is "Magna Proditor".
His character, mindset and desire for the "right" to play God have become synonymous with an outrageously disturbing form of hypocrisy GokaiWhite calls "Authoritative/Divine Privilege", which suggests that an exceedingly high status or tremendous power somehow grants individuals the "license" to inflict tragedy on those who don't deserve it, and still be viewed by the vast majority as the undisputed "good guy", often excusing it as "just doing their jobs" or serving a "higher good". The delusions that pervaded Bahamut's conscience, or solidified the lack thereof, serve to give the series' title a whole new, morbid layer of meaning.
Since Satan is referred to as a dragon in some sources, especially the book of Revelation (12:9), Bahamut's painting Ifrit in a satanic light to the people of Eos, and his own betrayal of humanity, ironically makes Bahamut the real "devil" of Final Fantasy XV, (and arguably the whole series) particularly in the context of Bahamut being literally dragon-like in appearance, a traitor to his kind who gave in to jealousy, and so unbelievably malicious.
The ways Bahamut symbolizes the seven deadly sins are as follows:
- Lust: Not (necessarily) of a sexual nature, but his obsessions are unhealthy ones nonetheless. He might have, at some point, entertained lustful thoughts concerning Shiva and/or other beings resembling beautiful women, or considered (sexually) torturing Shiva when she finally accepted the DracoRex has gone too far.
- Gluttony: His overreliance on the Crystal's energy to maintain his godly powers over space and time, regardless what happens to said Crystal or similar power source. Bahamut also refused to let anyone, even Lucian royalty, use the Ring of the Lucii's powers without incurring some heavy toll.
- Greed: Mostly his desire for power, but also his desire to conquer all the Final Fantasy worlds. Fearing the loss of his power or some other adverse effect on it is another important reason why he wanted to sacrifice the Lucian bloodline instead of take responsibility for his role in the spread of the StarScourge.
- Envy: The more powerful the beings he struck down or helped Warriors of Light strike down, the worse his envy for those like Bhunivelze grew. The fact that the Warriors of Light got less dependent on Bahamut as they grew stronger themselves fueled Bahamut's jealousy further, and it even extends to Summoned Creatures like Zodiark, Anima, Ark, Eden, and the Knights of the Round.
- Sloth: His refusal to better himself and devise a solution to the StarScourge Crisis without sacrificing so many lives, and ignorance of the consequences his actions can/will have. It can also refer to his squandering his godly powers by not saving the individuals he picked to be his pawns in Final Fantasy XV.
- Wrath: His killing, torturing, or mistreating of others who speak out against his ways and overinflating ego. With his lies being unraveled, Bahamut finally allows his anger at humanity and the other Astrals to override his ability to plan ahead and devise a contingency plan to return from the dead if he lost, which he does.
- Pride: The most dangerous of all, especially Bahamut's pride in his pragmatism and might-makes-right mentality, which suggests the idea that ultimate power grants him leave to do as he pleases without any consequences to himself.
- Bahamut is the second recurring character to be confirmed as the same being who merely changes his appearance in between mainline games and spinoffs, after Gilgamesh in Dissidia 012 Final Fantasy. This presumably applies to most other summoned creatures as well.
- Cid, Biggs, and Wedge do NOT count toward this context, as they are just "popular names" assumed by completely different characters.
- Bahamut's true characterization, as revealed through this page (and displayed in -The Dawn of the Future-), draws heavy parallels to Teridax: both started out as very powerful beings who did the right thing for the wrong reasons, but then became arrogant and evil, turned on those they were sworn to protect and seized control of a planet, but then finally met their end by the main hero, or because of him. He may have just surpassed even Kefka as the darkest, most evil villain in all Final Fantasy history, the impact made stronger and all the more upsetting with his former status as such an iconic summoned creature considered.
- GokaiWhite describes DracoRex as also being a symbol of his fury at Hajime Tabata(much like how Yiazmat in Final Fantasy XII was inspired by Yasumi Matsuno) for leaving Square Enix before -The Dawn of the Future- can be completed in it's entirety, saying: "This is not only about saving a beloved character; this is about holding all the Bahamuts and Hajime Tabatas of the universe responsible for their misdeeds; a wakeup call to their collaborators, who let their respect for such individuals override their morality, to own up to their acceptance of the hypocrisy of it all."
- Gokai also said, "The DracoRex's character is also a grander-scale allegory to the idea that Delita Heiral's ruling dynasty which he established by the end of Final Fantasy Tactics, if not Delita himself, will inevitably turn corrupt by his morally dubious ideology and become just like the purveyors of injustice Deltia had wished to expunge, in some form or another, reinforcing the idea that Ramza Beoulve is, especially morally speaking, the true hero that should be remembered by history". Fittingly, Final Fantasy Tactics also had themes of historical censorship long before Ardyn's backstory was truly fleshed out.
- He was once arch-rivals with Shinryu, and they competed fervently for what they personally referred to as "the Throne of the Gods". However close either got to this goal, they nonetheless became corrupted by their latent base desires for ultimate power.
- The Undying in Final Fantasy XII, being it's final boss, not only foreshadows Bahamut's antagonistic true colors, but the Dragon King also borrows some of the Undying's attacks.
- Bahamut's role as a malevolent parasitic deity is similar to the Elder God in the Legacy of Kain series(now owned by Square Enix through their acquisition of Crystal Dynamics), which perhaps even foreshadowed this.
- His attempted destruction of Palamecia, as mentioned above, gave Emperor Mateus the idea of conquering the world when he found out about it. This make Bahamut the real reason the Emperor became evil, whether or not the Stone of Iludia had anything to do with his corruption, as Bahamut seemingly refused to consider. He never even tried to destroy the stone himself, since his indifference/disrespect for lower life-forms, power-lust and appetite for destruction are the Dragon King's defining characteristics.
- According to a new rumor by GokaiWhite, Bahamut was the one who directed Jenova to Gaia and gave her the idea to control Sephiroth. He may also have something to do with the (true) origin of the Arbiters of Fate.
- His action of starting a time-loop just to make Noctis suffer and die over and over again for Bahamut's own amusement slightly echoes what Garland did to ensure his constant rebirth.
- Instigating this endless spiral of death also makes him a far more blatantly evil analogue to Sin and the Church of Yevon from Final Fantasy X.
- In fact, Gokai now believes that Bahamut had, at one point, wanted to become Sin through sticking with the plan to defeat him permanently, only to kill Yuna and her guardians upon letting Yu Yevon possess him. Of course, he'd have underestimated her and her guardians' own strength, or have realized it wasn't the ideal plan to reach his ulterior ultimate goal.
- Instigating this endless spiral of death also makes him a far more blatantly evil analogue to Sin and the Church of Yevon from Final Fantasy X.
- After his ultimate death, Bahamut's name became another word for "betrayer/backstabber", solidifying his synonymy with treachery. Though his name is not censored out of the histories (this would make whoever does so no better than Bahamut), many still prefer to call him the Great Betrayer to emphasize his shameful legacy.
- Assuming Noctis ever appears in Kingdom Hearts: Lost Firmament, Gokai wants to retcon Bahamut's treachery as a key part of the lore behind the ideology of the Oathbreakers(the fan game's main antagonists) by having Noct personally inform Sarah Serenity and friends about Bahamut's vile hypocrisy, that the Dragon King was the first of the Oathbreakers and their God.
- In Bionic Fantasy, Scryptorek's elaborate deception that Jikanmu was only "manipulating" the Toa Luminus into helping the Makuta's scheme, as well as the appearance of Kardahamut, was a foreshadowing to the revelation that Bahamut had been doing the same thing with the Warriors of Light up until ascending to godhood as shown in the FFXV Universe, which evokes the idea of trading one evil for another, if unintentionally.
