Beelzebub

Beelzebub is portrayed as both a fertility guardian god and the infamous fly demon known as the “Lord of the Flies.”

He is feared even among gods as “The One Cursed by Satan” and is believed to bring misfortune to anyone who becomes involved with him.

He appears as a young man dressed entirely in black, reminiscent of a scientist or a monk.

His defining traits are his broken ethics as a mad scientist and a deep-rooted desire to find someone capable of killing him.

He holds one of the highest levels of scientific and technical genius in Heaven.

Using that genius, he conducts horrific experiments primarily to discover a being who can end his life.

In the Record of Ragnarok tournament, he joins as the gods’ fighter in the eighth match, facing Nikola Tesla.

His participation is driven less by loyalty to the gods and more by the possibility that a human might finally be able to kill him.

Beelzebub is a textbook mad scientist with virtually no ethical restraints.

He keeps horrific experimental creatures in his heavenly laboratory and casually uses even fellow gods as test subjects.

His curiosity is cold and clinical, directed toward extreme results rather than moral considerations.

This is evident when he turns Hajun into a seed and implants it into Zerofuku simply because the conditions seem convenient.

Underneath this rational cruelty lies a profound self-destructive impulse.

His research, his interest in strong beings, and his participation in the tournament all stem from his longing for someone who can end his life.

He is fully aware of his own monstrosity.

He views himself as cursed and sees a grotesque, agonizing death as the only form of atonement for the loved ones he destroyed.

Despite his cruelty, he is capable of trust and respect.

His relationship with Hades in particular shows that Beelzebub can value others deeply, even if that bond is twisted by his guilt and self-hatred.

Beelzebub bears the epithet “The One Cursed by Satan” (Anathema).

Among the gods, it is widely believed that getting involved with him leads to disaster, causing him to live in isolation for a long time.

The core of this curse is his unique destructive trait called “Demonic Instinct of Life-Destruction (Destrudo).”

When his love for someone reaches its absolute peak, Destrudo takes over and forces him to destroy the very person he cherishes—against his own conscious will.

Because of Destrudo, Beelzebub is both victim and perpetrator of tragedy.

He sincerely loves, yet is compelled to murder those he loves, reinforcing his belief that he is a walking calamity.

This leads to a self-image of being Satan’s chosen ruin.

In time, he comes to accept that the “Satan” responsible for his misery is none other than himself.

Life as Anathema

In Heaven, Beelzebub lived with the reputation that he was cursed by Satan.

Gods believed that associating with him would bring misfortune, and most avoided him entirely.

In that loneliness, three angels reached out to him: Lucifer, Azazel, and Samael.

These three were curious about him and unafraid of his ominous reputation, becoming his first genuine companions.

With them, Beelzebub finally experienced daily life filled with joy, friendship, and acceptance.

Their presence gave him a reason to exist, easing his sense of being cursed.

However, this fragile happiness was shattered when Lucifer, Azazel, and Samael were suddenly murdered.

Beelzebub was convinced that the culprit was Satan, and revenge became his new reason to live.

Quest for Satan and Meeting Lilith

To hunt down Satan, Beelzebub began researching the demon’s true identity.

He teamed up with Lilith, Lucifer’s childhood friend, who shared his determination to uncover Satan.

Together, Beelzebub and Lilith journeyed across Heaven and the Underworld.

During this time, Lilith became another emotional anchor for him, deepening his ability to care for someone.

But at the end of this journey, a horrific truth emerged.

Beelzebub suddenly realized he was standing over Lilith’s corpse, having unconsciously killed her with his own hands.

In that moment, he understood the nature of Destrudo.

The “Satan” who killed his friends and Lilith was not some external demon, but Beelzebub himself, driven by his uncontrollable destructive impulse.

He tried to apologize to Lilith, overwhelmed by despair and guilt.

Lilith, in her final moments, commanded him to live on in their stead and carved a tattoo onto his body before dying.

This tattoo became a powerful mark that would not allow Beelzebub to die.

Every attempt at suicide was thwarted as the tattoo forcibly preserved his life.

Seeking Death in the Underworld

Broken by the realization that he himself was Satan, Beelzebub abandoned revenge as a purpose.

He now desired only to die and went to the Underworld in search of someone strong enough to kill him.

There he fought countless monsters, hoping to fall in battle.

Eventually, he reached Hades, the king of the Underworld, and challenged him.

Beelzebub lost the fight against Hades.

During their encounter, he explained that Lilith’s tattoo prevented him from dying and viewed it as a curse forcing him to suffer.

Hades rejected that interpretation, calling the tattoo not a curse but Lilith’s prayer for Beelzebub to live.

He urged Beelzebub to think about what had truly been left to him rather than fixating on death.

After reflecting, Beelzebub concluded that he still deserved to die.

However, he accepted that a clean, dignified death was not his path.

Instead, he decided he should live until he could die a death that was painful, miserable, vile, brutal, and ugly.

To him, such a death would be the only fitting atonement for what he had done to Lucifer, Lilith, and the others.

From that point on, his guiding principle became: “to find someone who can kill me” in the worst possible way.

This decision pushed him deeper into his grotesque research and experiments.

Hades became a crucial figure to Beelzebub.

Although Hades defeated him, he also gave Beelzebub a new perspective on Lilith’s tattoo and his own existence.

Hades gifted Beelzebub his divine weapon, the Staff of Apomyios, symbolizing recognition and trust.

Beelzebub, in turn, came to deeply respect and rely on Hades as his only emotional refuge.

Later, when Hades asked him to save his brother Adamas, Beelzebub agreed and performed surgery on Adamas.

This shows that Beelzebub’s actions are not solely guided by cold curiosity; he honors the requests of those he truly respects.

After witnessing Hades’ death in the Record of Ragnarok, Beelzebub’s inner feelings shifted.

He had always secretly wanted Hades to be the one to kill him, but losing his last emotional anchor twisted his desires.

His grief transformed into a new hatred toward humanity, whom he saw as responsible for Hades’ death.

This rage motivated him to participate in the eighth match, carrying a stronger intention to slaughter humans.

Hajun and Zerofuku

Hajun is a legendary berserker who once half-destroyed the Underworld (Helheim) with his overwhelming power.

His body eventually self-destructed because it could not withstand his own strength, and he disappeared.

However, traces of Hajun’s remains were left behind in the Underworld.

Beelzebub secretly collected and cultivated these remnants into a seed.

He then implanted this seed into Zerofuku, a god of fortune, without Zerofuku’s knowledge.

The host did not matter to him; Beelzebub chose Zerofuku simply because he was conveniently suitable and right in front of him.

During the sixth round of Ragnarok, when Zerofuku entered the arena, Hajun finally awakened.

He absorbed Zerofuku entirely and resurrected, much to Beelzebub’s scientific satisfaction.

As Zerofuku disappeared within Hajun, Beelzebub merely observed and remarked, “So this is what happens when the soil is good.”

He displayed no guilt or remorse, treating the entire event as a successful experiment.

After the sixth match ended, Beelzebub burned all research documents related to Hajun.

When confronted by Odin, who had deduced he was behind Hajun’s revival, Beelzebub did not bother to deny it or hide.

From his attitude, it is implied he destroyed the data not to conceal evidence, but because Hajun failed to be the one who could kill him.

Once he lost interest, the experiment, in his eyes, became nothing more than discarded data.

Adamas and the Cyborg Body

Adamas is the god of conquest and younger brother of Poseidon, who had previously been executed by Poseidon.

At Hades’ request, Beelzebub took on the task of restoring Adamas.

Originally, the plan was to regrow his body by cultivating the two halves that Poseidon had torn apart.

However, during the cultivation process, Adamas told Beelzebub that he had “terrible taste,” irritating Beelzebub.

Annoyed, Beelzebub abruptly changed course and forcibly transformed Adamas into a cyborg instead.

Despite this, Adamas actually liked the new, flashy mechanical body and commented that it was “pretty stylish.”

Beelzebub, amused, responded that Adamas “has good sense after all.”

This interaction shows Beelzebub’s unpredictable temperament and how his ego can twist the outcomes of his experiments.

Demonic Wingbeat (Balmura)

Beelzebub’s signature ability is “Demonic Wingbeat” (Balmura), which allows him to manipulate vibrations.

He specializes his left hand for defense and his right hand for offense, maximizing both sides of combat.

By controlling vibration, he can generate shockwaves, shatter targets, or dampen incoming attacks.

This dual specialization grants him extraordinary versatility on the battlefield.

Hermes describes Balmura as an ability that is “simple, and therefore infinitely adaptable.”

Brunhilde calls Beelzebub a god who possesses the strongest spear and shield, referring to his offensive and defensive mastery.

Within the Underworld, he is regarded as having some of the highest combat sense among its denizens.

His fighting style is calculated yet reckless toward his own safety, reflecting his lack of concern for his own life.

Staff of Apomyios

Beelzebub’s divine weapon is the Staff of Apomyios, given to him by Hades.

The staff is topped with a skull-like orb called Apomyios, which further amplifies his vibration ability.

By channeling Demonic Wingbeat through the Staff of Apomyios, Beelzebub can vastly increase the power and precision of his vibrations.

This combination allows the staff to function as both a devastating weapon and an impenetrable shield.

The name “Apomyios” comes from one of Zeus’s historical epithets, meaning “he who drives away flies” in Greek.

Ironically, it links directly to Beelzebub’s identity as the “Lord of the Flies,” highlighting the tension between him and other gods.

Seventh Round Aftermath and Warning to Brunhilde

After the seventh round, Beelzebub intervenes in an incident involving Adamas and Brunhilde.

Adamas attempts to kill Brunhilde to avenge Hades, but Beelzebub stops him, effectively saving her life.

While doing so, he issues a blunt warning to Brunhilde.

He tells her that not only he and Adamas, but many other gods harbor an almost uncontrollable urge to massacre humanity, and she should stay alert.

His anger is visible as he speaks, showing that his animosity toward humans has grown since Hades’ death.

Nevertheless, he leaves without harming Brunhilde, suggesting a complex sense of restraint and purpose.

Afterward, Beelzebub goes to Hermes and asks him to inform Zeus that he wishes to fight in the eighth round.

This firmly sets him up as the gods’ next representative against mankind.

Eighth Round: Beelzebub vs. Nikola Tesla

In the eighth match of Ragnarok, Beelzebub faces Nikola Tesla, a human genius scientist.

The duel is not only a clash of power but also a thematic battle between two extreme forms of scientific obsession.

During the fight, Beelzebub recalls his past with Hades and realizes how much Hades influenced him.

He concludes that Hades’ difficult personality has made him “even more troublesome” than Hades himself.

Deep down, Beelzebub had always wanted Hades to be the one to kill him.

However, having witnessed Hades’ death at humanity’s hands, his longing for death transforms into a desire to annihilate humans.

In battle, he shows no regard for his own body or survival.

He unleashes relentless attacks, repeatedly pushing himself beyond safe limits.

He even uses a forbidden technique called “Void God”, something Hades had explicitly banned him from employing.

This technique emphasizes how far he is willing to go, breaking taboos and risking everything in his desperation.

Normally, Lilith’s tattoo would interfere and prevent him from dying.

But Beelzebub stakes his very life on his will, momentarily overriding the tattoo’s protection, forcing it to stop interfering with his self-destructive assault.

As the fight reaches its climax, he refuses to believe Nikola Tesla would launch a final attack without a plan.

Trusting in Tesla’s intellect, Beelzebub reads and counters his ultimate move, successfully defending himself.

He then lands a fatal blow on Tesla, causing Tesla’s complete annihilation.

With this, Beelzebub secures victory for the gods in the eighth round.

Reflections After Victory

After the match, Beelzebub looks at the Staff of Apomyios and mutters that Hades has “interfered” with him once again.

This implies that Hades’ influence—through the staff and his teachings—still shapes Beelzebub’s actions and survival.

He observes how the gods suddenly shower him with praise after his victory.

Seeing this swift change of attitude, he remarks that gods, humans, and even himself are not so different in their fickleness and hypocrisy.

He then quietly leaves the arena, his inner emptiness and unresolved desire for death untouched by his triumph.

The victory fails to bring him satisfaction, only more confirmation of his own emptiness.

Confrontation with Odin and Buddha

After receiving medical treatment post-battle, Beelzebub appears during an argument between Buddha and Odin.

He interrupts, offering his own analysis of Odin’s hidden objective.

Beelzebub speculates that Odin’s long-held wish is the revival of the primordial gods.

He tries to ask Odin directly about this assumption, provoking Odin’s anger.

The tension between them escalates to the brink of a fight.

Only the intervention of Thor and others prevents a full-scale confrontation.

In the ensuing conversation, Beelzebub turns to Buddha.

He confesses that he was the one who implanted Hajun’s seed into Zerofuku.

He bluntly asks Buddha whether he hates him for what he did.

Buddha’s response, however, is not driven by hatred or easy condemnation.

Hearing Buddha’s answer, Beelzebub reassesses him.

He concludes that Buddha might actually be a being capable of killing him someday.

Beelzebub then tells Buddha that, if he ever feels like it, he should come and kill him.

With that invitation, he walks away, once again pursuing his twisted wish to eventually die at the hands of a worthy opponent.

Beelzebub’s catchphrase-like observation when experiments go “well” is: “I see… when the soil is good, this is what happens.”

This line encapsulates his view of living beings as experimental “soil” rather than individuals with intrinsic value.

His voice in the anime adaptation is provided by Daisuke Namikawa (in the original Japanese cast).

Combined with his quiet tone and measured speech, the performance highlights both his eerie calm and underlying madness.
