The lord of the flies, Beelzebub was originally a Canaanite deity named Baal and was later explained to be one of the seven princes of Hell in Christian sources. He is also considered to be synonymous with Satan. In Judaism, he was a mockery of the religions surrounding them that worshipped Baal, and in Rabbinical texts the name Ba'al Zebub was a mockery of the religion of Baal. Some scholars believe the name Ba'al Zebub ("Lord of the Flies") was a way of referring to Baal as a pile of dung and his followers as flies, as well as a pun on Ba'al Zebul ("Lord of the High Place").
In Catholic demonology, he is sometimes considered to be one of the first three angels to fall from heaven, along with Lucifer and Leviathan. He is said to be one of the seven demon princes, and is often associated with pride, gluttony and the worship of false gods.
In the fifth area of the Expanse, the Mountain of Horror, the protagonist comes across a village of anthropomorphic flies. There is a dungeon nearby in the depths of which a battle with Beelzebub awaits. However, if Frog Bael is in the protagonist's company, Beelzebub will ask to fuse with him. If this is allowed to happen, Baal will emerge from the two and gladly join the ranks of the protagonist's digital demon horde. If the protagonist chooses not to let them fuse, or decided to kill Bael, he will fight Beelzebub. If he is fought, Lucifer's Sword is found on the ground afterwards. Regardless of whether he joins or fights, the Palace Stone gets changed into the Palace Ring.
"Origin: Babylonia. The lord of Hell that presides over gluttony. He is king of the fallen Seraphs and is said to be Lucifer's second-in-command. His original name is Baal Zevuv in Hebrew ('Lord of the Heavenly Dwelling'). When he was passed into Christianity, his name became Baal Zebub ('Lord of the Flies')."

Beelzebub appears as Lucifer's right-hand man in Shin Megami Tensei. Late in the game, Louis Cyphre sends the protagonist over to Shiroganedai. Should the protagonist follow the Law or Neutral alignment paths, Louis Cyphre will lie about what is hidden there, speaking of a powerful weapon; should the protagonist take the bait, Beelzebub will engage them in battle. In the Chaos alignment path, Louis Cyphre will tell the truth, and Beelzebub joins the protagonist instead.
Beelzebub appears in Castle Kether in the Expanse. He is a voluntary challenge; if Aleph walks into his chamber, he will challenge him and he may decline and even come back later. He doesn't need to fight him to complete the game and can be skipped entirely, although Aleph must defeat him in order to create him through fusion.
Beelzebub only appears in the updated release of Nocturne titled Shin Megami Tensei III: Nocturne Maniacs. Should the Demi-fiend accept the old man's request of retrieving all of the stolen Candelabra, he can face Beelzebub in the Fourth Kalpa of The Labyrinth of Amala, in Hell's Hall.
The Fourth Kalpa of the Labyrinth of Amala is arguably one of the more difficult sections to venture into, as the majority of its sections are areas with a curse cast by Beelzebub himself, which periodically inflict damage and cannot be avoided by using a Float Ball or Liftoma, since the curse encompasses the whole area and not just the surface. Furthermore, the random enemy encounters in said areas consist of stronger demons.
There is also the infamous "12 Meters of Eternity" where a warp takes the Demi-fiend to varying places in Beelzebub's realm depending on the phase of Kagutsuchi. Beelzebub's inner sanctum can only be accessed during a New Kagutsuchi phase, which is considered "the darkest hour."
Upon reaching Beelzebub's throne, Beelzebub appears in his human guise and expresses gratitude towards the Demi-fiend for helping to further his master's plans, and will offer his assistance. He is also slightly amused by the fact the Demi-fiend had no idea of the true purpose of the Candelabra and chides him for his naiveté in so recklessly aiding Lucifer's plan having no idea of what it truly entailed.
As a prerequisite for his assistance, however, Beelzebub would like to test the limits of the Demi-fiend's demon powers firsthand. He then reverts to his true fly form to engage him in battle.
Beelzebub holds the distinction of using the strongest Almighty/Death skill, Death Flies, which instantaneously kills all present characters not immune to Death. If the targets are immune to Death, they will still be subject to some Almighty damage. Beelzebub also sports a "hidden" resistance to Physical, Ice, Electricity and Force attacks, which he will only take half damage from despite them not being shown as resisted against.
The Demi-fiend can summon Beelzebub's human form (Baal Zebul) in the Cathedral of Shadows after defeating Beelzebub and after reaching Level 84 or above. The fly-form Beelzebub can be obtained by evolving Baal Zebul by completing his skillset when the Demi-fiend is at Level 95 or above. This is the only way to later gain use of Beelzebub's "Death Flies" skill. Beelzebub's fly form is also required to open a sealed door in the Fifth Kalpa.
Beelzebub (Human) appears as the central boss and orchestrator of the events within the Lord of the Flies quest in the Alternate Shinjuku. His fly form is only alluded to in the final cutscene players see when leaving the area. He also appeared in the Tokyo Nostalgia series of bossfights. In the Judgement Battle event, Beelzebub (Fly) was introduced as one of the bosses. His summon PG and later the summon PG for his human form were made available in the end chests for this event. In the Devil Royale event, a swarm of Beelzebub (Fly) spawned after players defeated Ishtar and Astaroth.
They were both added as Secret Room plug-ins in Summer 2013. Beelzebub (Human) is a triple fusion of Astaroth, Moloch and Ghoul. Beelzebub (Fly) is a triple fusion of Astaroth, Moloch, and Baphomet.
Beelzebub appears in the Empyrean Ascent as a bonus boss on a New Game Plus. He bestows the Lucifer Mail (140 DF, Resist elements, Null Curse) on defeat.
Of the four superbosses in this game, Beelzebub is the most dangerous of them all and should ideally be faced last. Unlike the other bosses, Beelzebub has no tolerance for debuffs, and reacts to them by casting Doomsday, a powerful almighty spell that's all but guaranteed to kill. Refrain from using Debilitate or Antichthon to avoid an untimely death. He doesn't use Doomsday in response to buffing; he just casts Dekaja, and is the only boss among Louisa Ferre's generals to actually use this skill.
The rest of the fight is more straightforward. Beelzebub possesses several skills that the other of Lousia's generals sport, but he has a preference for spamming Antichthon to weaken the party. He lacks resistance to Gun, so spamming Riot Gun is an effective way to bring his health down.
If he falls to around 3,000 HP, he will fully heal himself with Diarahan; gauge his health and aim to burst him down from there. If the Diarahan goes off the battle might as well be over, as trying to wear down a full health bar all over again will have the battle go over the usual 20-turn time limit. If that time limit is crossed, like with the other generals, he will start spamming Doomsday.
"The slaying of a king is like the slaying of a god. Now, I must put an end to your blood streaked soul. But, rejoice, for I shall use your body as my new vessel."
—Beelzebub, Shin Megami Tensei IV
The true form of Baal, who is fought in the Challenge Quest, Rebirth of an Overlord. He seeks to kill Flynn for being an "extreme danger" and for slaying his king, which to Beelzebub is the same as killing a god. Beelzebub plans on making Flynn's body into his new vessel once he kills him. Upon being defeated, Beelzebub warns that he shall not perish and will return just as thousands of flies appear from filth, dying afterwards. His body becomes a swarm of flies that scatter away upon his death.
Following Lucifer's defeat, Beelzebub appears as a member of the Divine Powers. He is one of the Defenders of the Cosmic Egg alongside Apsu and Seth, assuming the form of Baal through Inanna's power.
Beelzebub can be summoned in the Cathedral of Shadows through special fusion of Baal, Ghoul and Morax. He can teach Nanashi the Mamudoon, Riot Gun and Thunder Gods skills through his Demon Whisper. He benefits from learning Gun, Electricity and Dark skills.
Beelzebub's appearance in this game is unique in the series, as instead of he, it is a she, depicted as a female wearing an outfit designed around a fly. Beelzebub is fought in Ahrqa of Paranoia, if the protagonist is on a route where they defeat Lucifer, they will fight Beelzebub last, otherwise they will fight her first.
"Hmmmmm? Who's there? Hmm... I smell the scent of humanity. The scent of a fool, whose futile strength means nothing. But, still, I never imagined a day would come in which I might unleash my power once again... I am Beelzebub, the keeper of this corridor and the king of Hell. The five Manji of Time shall not be allowed to fall into your hands!"
Beelzebub appears as the ultimate boss and highest level summonable demon in the game. He must be defeated at the lowest level of the Training Hall.
Raidou must save at the last save point in the game and return to the Training Hall. A voice will speak to Raidou when he enters the northern section of the bottom floor. Then Raidou must collect 3 special items to prove his worth to Beelzebub. These items are obtained by fighting 3 Hyakki Yakou battles (Battles where 100 demons attack) at certain moon phases in certain sections of different floors (A Kudan will hint at their location a phase or two before the battle's set phase). Then Raidou can fight Beelzebub in the same spot where he heard the voice, but he must beat some Ukobach and Nebiros before Beelzebub will appear.
"Lord of the Flies, and the prince of Hell. His flies carry souls down to the abyss. He may be the bastardization of the Canaanite god Ba'al."
—Gouma-Den devil chart
Beelzebub can be normally summoned once Raidou reaches Lv. 75 or above. Beelzebub will also fight Raidou during the battle with Lucifer's true demon form. In this battle, he is in fact an aspect of Lucifer, taking the form the Mushibito see him as. Once he realizes he wasn't talking like the real Beelzebub, Lucifer proceeds to speak more like him.
Beelzebub appears as the ultimate Persona of the Devil Arcana. He is available to be summoned once the protagonist reaches Lv. 81 or above. Beelzebub's fusion prerequisite requires the protagonist to perform a hexagon-spread fusion consisting of Lilim, Vetala, Incubus, Succubus, Lilith and Abaddon in the Velvet Room.
Beelzebub returns as the ultimate Persona of the Devil Arcana in Persona 3 FES, retaining most of his attributes. His humanoid form, Baal Zebul of the Moon Arcana was also added to the Persona repertoire, which can be summoned once the protagonist reaches Lv. 71 or above and fuses the appropriate Personas resulting in a Persona of the Moon Arcana. As different Personas of the Devil Arcana were added, Beelzebub's fusion prerequisite now requires the protagonist to perform a hexagon-spread fusion that consists of Incubus, Succubus, Pazuzu, Lilith, Abaddon and Baal Zebul in the Velvet Room. The strongest distinct bludgeon-class weapon, "Corpse Staff," can also only be acquired via fusing Beelzebub with a Nihil weapon via the Weapon Fusion system.
Beelzebub appears as the ultimate Persona of the Devil Arcana in Persona 4. His humanoid form, Baal Zebul, instead appears as a Persona of the Moon Arcana, which can be summoned once the protagonist reaches Lv. 77 or above.
Beelzebub, on the other hand, is available to be summoned once the protagonist completes the Devil Arcana Social Link with Sayoko Uehara. Furthermore, the protagonist must reach at least Lv 81 or above before summoning Beelzebub. Beelzebub's fusion prerequisite requires the protagonist to perform a hexagon-spread fusion consisting of Pazuzu, Belphegor, Belial, Mot, Seth and Baal Zebul in the Velvet Room.
In episode 17 of Persona 4 the Animation, Yu does his second on-screen fusion to make Beelzebub of the Devil Arcana, requiring six Arcana cards, similar to the way he is fused in the game. He was able to finish off Shadow Naoto with Megidolaon and completely destroy the battlefield.
Yu summons Beelzebub while under the possession of Kunino-sagiri during their battle in Heaven. Beelzebub was about to use Megidolaon against the Investigation Team, but Yu was able to gain control over his body and call off the attack.
In the True Ending special, Beelzebub appeared once more to attack Margaret'sLoki and bring a message of support to Yu from Sayoko, as he began to regain confidence.
"Demonic Lord of the Flies whose insect minions carry souls for him to control. He is mentioned in the Bible as a leader of evil spirits and is seen as a powerful demon."
—Persona 5 background
Beelzebub is the ultimate Persona of the Devil Arcana and the Devil Confidant with Ichiko Ohya must be completed before he can be fused in the Velvet Room. He is the second of two Personas to learn the Curse Amp and Repel Ice skills and the only source of the Demonic Decree skill. When itemized through Electric Chair execution, Beelzebub produces the Fleurs du Mal axe for Haru Okumura, which has 308 ATK, 86 ACC and increases her Magic stat by five and grants her attacks the Dizzy (high) effect.
Beelzebub is present in its two forms - Baal Zebul and Beelzebub. They are the highest-levelled Sub-Personas of the Hierophant and Devil Arcana respectively. Beelzebub's fly form can only be obtained through a special fusion involving Baal Zebul and Astaroth, and this special fusion can only be unlocked with the Gluttony's Mark that is found after defeating a Namtaru in the Theater District.
Zebul and his brothers have declared war on Enoch and his angels before the game began. Their forces clashing on Earth, Tenkai and Makai. Eventually Akira arrives at the Deep Hole and defeats both Fake Belphegor and Berith. He mentions that Amy Kashihara came and begged him to find a way to restore Valhalla, which he did by sending her to the world of Fire, Muspelheim. After his defeat it is revealed that the Zebul he fought was a fake like his brothers.
In Muspelheim, the real Zebul can be found as a statue. The blood of the wicked will free him from his imprisonment and he will offer to join Akira after revealing that he was imprisoned by the demons pretending to be his brothers. The Fake Zebul like the other Fake Brothers has a different face and skin tone when compared to the real one.
Known as Beelzebu (ベルゼブ, Beruzebu)?, he is the final boss of Jin's route. He had revived the Imperium to sacrifice souls in order to be free of the seal placed on him in ancient times by the Messiah. Thanks to his servant Pazuzu manipulating Jin into using the crystals to destroy his seal, he is freed. With his newfound freedom, his first act is to kill his servant Pazuzu as he had served his purpose. Beelzebu does not switch elements thanks to the crystals like Gaap, instead nulling all damage of an element as long as the crystal that represents that element isn't destroyed. Beelzebu will teleport to any crystals attacked on his stage and acts like a magnetic force that brings all nearby foes to him. Once he dies, the Dark Palace begins to fall apart, forcing Jin and Rand to flee.
Not to be confused with Zebul, who is a recurring character in the Devil Children series.
"So, you ignorant shadows have arrived at last. Behold, I am Beelzebub! Now is the time to rise out of purgatory and cover the present world with terror and corruption. Kneel before the Wicked King. Offer yourselves to me!"
—Beelzebub, before the second battle
Beelzebub appears as an optional boss. Unlike other optional bosses, the party is required to fight him twice before killing him for good. He can be challenged after retrieving the Key Item Red Key in the Svadhisthana Waterways and using it to unlock the red wall in the Vanguard's Base in Svadhisthana. The party will eventually run into a member of the Embryon, who proclaims that he would be a more suitable leader for the Embryon. Transforming himself into the human form of Beelzebub, the member engages the party in a battle.
During the first battle, Beelzebub will start off using Mazionga and Mind Scream and later switch to turns of Mahamaon/Mamudoon or Makakaja/Megidolaon. Skills such as Resist Death/Expel or Null Death/Expel and Null Nerve will come in handy. Also access to the Makanda, Debilitate or two party members with -nda skills will allow them to remove his Makakaja boosts via the Dekaja combo.
After defeating the human form of Beelzebub, the Embryon member runs away, but not before telling the party that he will become stronger upon their next encounter. He can later be challenged in the Samsara Tunnels under Manipura. Upon the second encounter, Beelzebub transforms into his true, fly-form, sporting more powerful skills and attributes. Throughout the battle, Beelzebub retains several attacks reminiscent of Shin Megami Tensei III: Nocturne, including his distinct instant-kill attack, Death Flies. He will also constantly use Mazandyne and Maziodyne followed by Physical attacks on characters with Shock status. Beelzebub will use Dekunda every so often, but may react immediately if 4 debuffs are applied to him.
Defeating Beelzebub's fly-form will grant access to the ammo Magatama and the item "Tyrant's Skull," which unlocks the High Priest Mantra, granting the access to several of Beelzebub's skills. Next to the nodes containing the Magatama ammo and Tyrant Skull is the third node which contains the Murder Rock, an reusable item that grants unlimited castings of Mamudoon. Players will also net the Karma Ring which protects the wearer from Dark-based attacks, which can be equipped in the sequel.
Belzaboul starts the battle with 4 other teams of demons, but once 2 of these teams are defeated, he converts all other surviving teams into maggot flies, and begins using the Spawn ability. The Spawn attack has the ability to inflict the Egg ailment, which, after one turn, inflicts a large amount of Almighty damage to the afflicted team member (most likely killing them in the process) while spawning another team of maggots. In order to prevent this, it is necessary to heal the ailment status or replace the infected team member.
During Amane's or Naoya's routes, Belzaboul is summoned once again along with the other Bels during the fight with Babel.
Because Belzaboul is a Bel, unlike in other games where Beelzebub is featured in, he cannot be used by the player at all and is exclusive as an enemy unit.
"Lord of the Flies and the prince of Hell. He is established as a high-ranking demon in the Bible, and his flies carry souls down to the abyss. He may be a bastardization of the Canaanite god Baal."
—Devil Survivor 2 compendium
Beelzebub shows up as a bonus boss on a New Game Plus during the 6th Day at 19:00, as soon as the protagonist gets the opportunity to attack Mizar. This battle will remain available until the end of the day.
Beelzebub carries a tricky gimmick to his fight: when the party defeats his demon teams scattered across the map, his resistance to one element will change: first to Null, then Strong, then neutral resistance, then Weak. However, after the protagonist engages Beelzebub, regardless of how many demon teams have been defeated, Beelzebub will raise his defenses to reflect all non-Curse elements, and switch to a different set of demons. The sole exception to this is Almighty, which he inherently resists despite not having Anti-Almighty as a passive ability. Beelzebub's element-dyne and elemental Amp skills will also change accordingly to reflect which element the summoned demons are related to, and when he summons a wave of phys-oriented demons he switches them with Deathbound, Mighty Hit and Phys Amp.
The protagonist either has the option of continuously exterminating the demons Beelzebub summons until the right wave is present, or can simply hammer away with Almighty attacks once a team gets within attack range. Anti-Almighty is nearly mandated for surviving his Holy Strike and Ultimate Hits.
Defeating Beelzebub earns the Fly Swatter title and the ability to fuse him in the Cathedral of Shadows. This fight also presents the only opportunity to crack Holy Strike.
"The King of Hell, known as "Lord of the Flies". By making them carry the souls of the dead, he keeps his flies he rules in order. In the Bible, he is mentioned as one of the most formidable demons of high rank. It is also said that he was once the lord Baal of Canaan who was punished and became Beelzebub."
"It would seem you are the ones I've heard about."

"What? You're still runts. Why is Louis Cyphre afraid of you? If he refuses to attack you, then I shall be the one wading through a pool of blood. ...To think the blood I would wade through would be my own... Now I know why Louis Cyphre fears you..."
