It is said she was born from the left eye of Izanagi."— Amaterasu's compendium info from Shin Megami Tensei: Strange Journey"A god of Japanese legend, born along with Amaterasu and Tsukuyomi.

Two Gods of Japanese lore who were born from Izanagi after he washed himself to cleanse him from the filth of Yomi.
- Amnesiac God: In Strange Journey, Amaterasu appears under the guise of Kinmamon in Sector Eridanus in the Schwarzwelt. She appears to be lost and confused, drawn to the powers of the land by her nature as a mother goddess. The Schwarzwelt's powers were trying to incorporate her into the group of the Demon Mothers, and she wound up talking senseless gibberish in a corner on Eridanus until the Protagonist, with the aid of Ame no Uzume and Futotama shone a magical mirror upon her, waking her up from her delusional dreams and allowing her to leave the dimension with her caretakers.
- Character Filibuster: After freeing the Shinto gods in II, Amaterasu proceeds to go on a fairly lengthy rant about how the vain, grasping "Hebrew gods" (literally Hebrew gods, straight from the Japanese script, not an invention of Aeon Genesis) tricked the Kunitsukami into locking the Amatsukami and then turned on the Kunitsukami themselves. To anyone from Abrahamic Religions, it comes across really uncomfortably.

- Relationship Values:
- In Persona 4, Konohana Sakuya will evolve into Amaterasu once the High Priestess Social Link reaches Rank 10, making Amaterasu the ultimate Persona for Yukiko Amagi. Likewise, Jiraiya will evolve into Susano-o once the Magician Social Link reaches Rank 10, making him the ultimate persona for Yosuke Hanamura.
- In Persona 5, Goemon will evolve into Kamu Susano-o once the Emperor Confidant reaches Rank 10, making Susano-o (under an alternate name) the Ultimate Persona for Yusuke Kitagawa.
- In Devil Survivor 2, Amaterasu is a Unique demon that doesn't require a particular fusion combination to create. Instead, the player must achieve a Fate level of 5 with Otome Yanagiya before it is available. Once this has been achieved, it is unlocked for fusion on all subsequent runs as long as the player imports his/her save. Susano-o is also a Unique demon that must be unlocked by getting to Fate level 5, but with Keita Wakui instead.

- Sealed Good in a Can: In II, with the rest of the Shinto Gods.
- Side Quest: In IV, Futotama, found at the Meiji Shrine in Shinjuku, explains that Amaterasu was sealed away and asks that the player obtain the three imperial regalia from demon's domains around Tokyo to revive her. She bestows the Torifune's Shrawl upon resurrection.
- Signature Move: Amaterasu has Godly Light in Nocturne.

- Bonus Boss:
- Digital Devil Saga 2:
- Vishnu appears as an optional boss in a room opposite that of Shiva's. To meet with Vishnu, the Embryon must first prove their worth to his avatar Narasimha and obtain his sword. Upon meeting the Seraph, Vishnu states that it has been a while since the dharma (righteousness) has vanished from people's hearts and been replaced by adharma (wickedness) as it has now. He claims that he must cleanse this impurity by destroying Seraph and the others, and the only way to change his mind is for them to show the strength of their dharma. In Vishnu's room is the bullet Pandemonium, the strongest in the game, and defeating him infuses the Nandaka with his power, unlocking the God of Light Mantra.

- Digital Devil Saga 2:
- Combination Attack:
- "Trimurti" from Persona 2 by the personas Shiva, Vishnu, and Brahma. It will KO all non-boss enemies.

This only applies to Innocent Sin since it was nerfed in Eternal Punishment.

- Eye Beams: Shiva's Pasupata is a Wave-Motion Gun shot out of his third eye.
- Fusion Dance:
- The traditional method of fusing Shiva from Barong and Rangda originated from the first game.

Cerberus is one amongst the earliest of demon allies to appear as part of the Megami Tensei franchise. His roots put him as far back as the very first Digital Devil Story: Megami Tensei publications.
- Bragging Rights Reward: In Shin Megami Tensei III: Nocturne, Cerberus first appears at the Burial Chamber in the Amala Labyrinth's First Kalpa, where it will challenge Demi-Fiend to prove his worth as a demon by quickly vanquishing once more those that he has once killed in the Vortex World using the Black Visor. After meeting all the requirements and starting a new cycle, meeting with Cerberus again in the same location will have him take Demi-Fiend to his master's resting place instead at the Tomb of Yomi in the hidden 666th floor, where Demi-Fiend will receive an extra Press Turn.
- Crutch Character:
- Shin Megami Tensei I: Because of Pascal's former loyalty towards his master passed on to him by the fusion, Kerberos can be used even when his level far surpasses that of the Hero—something that generally is impossible. He aids him in only one battle however, disappearing through a teleporter after a boss fight. He later rejoins in Tokyo Destiny Land provided you give him a Golden Apple.
- Shin Megami Tensei II: Cerberus first joins you on the quest Madam gives you: Find and bring back Hanada. After the quest, he leaves the party. Later when Valhalla is swallowed by Abaddon, you will find him at the former entrance to the city from the underground passageway. He joins your party shortly after meeting him for the 2nd time.
- In Shin Megami Tensei if... there is a sidequest involving a computer disk that unlocks a Cerberus even if you're at the low low level of 20. You can probably most comfortably access the resolution of this quest between the dungeons of Sloth and Envy/Wrathnote . Well, Envy/Wrath starts with your main character losing their human partner for that dungeon. Don't you feel good having this mon 2-3 times your level just in case?
- "Get Back Here!" Boss: In a Challenge Quest from Shin Megami Tensei IV where he always flees after his Hell Horde takes a certain amount of damage. He fights for real after being chased down three times.
- HeelFace Turn: The Cerberus from Tokyo Revelation was a demon sent to kill the Protagonist by Ose's dragon, Gagyson. The Monk who defeats him convinces him to protect the protagonist in the name of his master Hecate instead.
- The Horde: Cerberus is leading a Hell Horde in Shin Megami Tensei IV, which is made of Fire related beasts.
- Legacy Character: Averted, the Cerberus that appears in Shin Megami Tensei II is the same one that appeared in the first game.
- Multiple Head Case: Averted for his original design as he has a single head. Soul Hacker depicts the similar design but with the three heads that he is most familiar with, as well as his design in Digital Devil Saga and Persona 3. It is to reference the original novel that the Megami Tensei franchise was based on.
- Mythology Gag:
- The reason why Cerberus is usually portrayed with one head is not because of graphical limitations (somewhat) but because that's how he was portrayed in the original Digital Devil Story novel.
- Cerberus takes you to his master's grave in the land of Yomi in Nocturne. This is a reference to Akemi Nakajima who is also the reincarnation of Izanagi.
- Playing with Fire: He is primarily affiliated with Fire skills.
- Tragic Monster: in Digital Devil Saga, due to Lupa not eating flesh when needed to.
- You Don't Look Like You: He typically appears as a white dog with a lion-like mane, unlike the Cerberus of Greek mythology. However, his appearance in Soul Hackers (which is similar to his original design), the Atma Avatar of Lupa and Koromaru's Persona are three-headed.
- A phantom copy of a living being. The name comes from the German phrase "double goer" Doppelgangers are a sign of bad luck. Often, others see your doppleganger from afar, but it is said you may also see your own doppleganger right before you die.— Doppelgänger's compendium info from Shin Megami Tensei: Strange Journey
A Doppelgänger can transform into any person it sees. It is said that whomsoever meets it will die within a few days, and much folklore stems from this creature. They may also become physical incarnations of psychological ailments.
- Attack Reflector: Doppelgangers usually are resistant to physical skills of all kinds, usually being capable of reflecting all physicals attacks out-right. This could be attributed to their own nature as shadow copies of the protagonist, were all the harm done to them goes back to the protagonist, for being one and the same.
Long, Gui Xian, Feng Huang, and Baihu (The Four Gods)
The Four Gods are the central figures of an ancient Chinese system of astrology and geomancy which was imported to Japan and absorbed into Onmyodo mysticism, among other beliefs. In this system, there were 28 'star houses' (constellations) which ran the circumference of the sky. The Heavenly Emperor divided the sky into the northern, southern, eastern, and western quadrants, each with 7 star houses; each quadrant was ruled by a divine beast.
- All Your Powers Combined: In several games in the series (including Strange Journey, Shin Megami Tensei IV, and Persona 4), using all four of them in a Special Fusion unlocks Huang Long/Kohryu, one of the strongest demons in the game that it appears in.
- Bonus Boss: After the party has reached the top floor of the final dungeon in Digital Devil Saga and if the player returns to the bottom, a Tribe member will notify Serph that several enemies have occupied old areas, later to be called the Four Guardian Beasts.
- Evolutionary Levels:
- In Nocturne, Gui Xian can be obtained by evolving Nozuchi.
- The player can get Seiryu in Nocturne by leveling a Mizuchi to level 40 or until it evolves. It has the ability to drain Ice attacks and null Expel. However its weakness is Fire.
- Sadly Mythtaken: The vermillion bird that represents the South is called Zhu Que. The Feng Huang is something completely different, but the games confuse them almost every time they use their Chinese names.
Bishamonten, Jikokuten, Koumokuten and Zouchouten (The Four Heavenly Kings)Four powerful Buddhist devas: Bishamonten, Lord of the North, Jikokuten, Lord of the East, Koumokuten, Lord of the West, and Zouchouten, Lord of the South, under the service of Taira no Masakado.
- Affably Evil: The Four of them are friendly fellows while being part of the Chaos faction in Shin Megami Tensei: Strange Journey.
- Barrier Maiden: The Four act as a barrier between the physical and demon worlds in Devil Survivor.
- Bonus Boss
- In Shin Megami Tensei III: Nocturne, Bishamonten appears first at the Temple north of Ueno Park after finding the Kimon Sphere, and second in the Bandou Shrine. After the first fight, the player will receive the Gundari Magatama, and Bishamonten will tell the player to collect all of the Magatama and find him again with his master. After acquiring the Lord's Blade after collecting all 24 Magatama, the player can access the Bandou Shrine and fight the four Devas for the right to receive the Masakados Magatama.
- In Shin Megami Tensei: Strange Journey, you can fight them if you satisfy their conditions.
- Broken Bridge: You must beat them on the Neutral or Law routes to access the Cathedral in Shin Megami Tensei I.
- Dual Boss:
- Evil All Along: In Shin Megami Tensei IV the four of them appear to Flynn in a Neutral-only quest involving helping Tokyo. In Apocalypse they are revealed to actually be members of the Polytheistic Alliance and their challenge to Flynn becomes a Secret Test of Character for the Alliance Evil Plan.
- Improbable Weapon User: Koumokuten uses an ink pen and scroll in Devil Survivor and Zouchouten uses a sutra made of pearls in Nocturne.
- Optional Party Member: On the chaos route of Shin Megami Tensei I, they will join the party if the protagonist is strong enough.
- Secret A.I. Moves: In Devil Survivor, the Four Heavenly Kings have their unique racial ability if you fight them as bosses, while the fusable versions are just regular Kishin.
- Skippable Boss: They will join the party in Shin Megami Tensei I without a fight if the protagonist is strong enough for them on the Chaos Path.
- The Unfought: Jikokuten was dead before the events of Devil Survivor.
- Wake-Up Call Boss: Bishamonten in Devil Survivor. Not only is his fight the second with Rangda enemies (which Repel Physical, making Atsuro and Izuna completely useless), his Hassohappa (which can deal 1000+ damage to the entire party) makes it almost impossible to approach him unless you at least Null Phys. Not to mention he has (respawning) allies that can heal his massive HP stores (making Hassohappa hit worse). While most battles so far were almost all affairs where you mostly attack and exploit weaknesses, this one puts emphasis on defense using passive abilities.
- As Long as There is Evil: Humorously, Black Frost makes this claim if you use him in a fusion in Devil Survivor 2.
- Berserk Button:
- In Strange Journey, do NOT call yourself a "hee-ho" around Jack Frost or Pyro Jack unless you want them to have a free turn.
- In the same game, calling Pyro Jack a mascot is a very bad idea.
- In Shin Megami Tensei IV, call yourself the main character and he tells you about how his father said to kill the main character. Free enemy turns ensue.note
- In Strange Journey, do NOT call yourself a "hee-ho" around Jack Frost or Pyro Jack unless you want them to have a free turn.
- Beware the Silly Ones: Unlike a regular Frost and despite his appearance, King Frost is ruthless and his power unyielding. He is not friendly and likes to exercise his status as a king to even go so far as to consider his summoners as his subjects as well.
- Bonus Boss:
- Raiho is an optional Boss fight in both Soulless Army and King Abaddon. He can only be faced in New Game Plus in Soulless Army and a case file on the first playthrough onwards in King Abaddon. He also summons demons to help him.
- King Abaddon also has the Jack-san Five which are a group of four Black Frosts and one Jack Frost. They are creating noise pollution with their music and Raidou has to put an end to it.
- After Serph and company defeat Mick the Slug in Digital Devil Saga, King Frost takes the opportunity to reoccupy Coordinate 136 with his own demons. Upon reentering the castle, Serph encounters two Pyro Jacks fiddling away at a treasure chest. Having tried their luck, the Pyro Jacks turn to the party to find a suitable key within the castle promising that the treasure within is for Embryon to keep. It was however a lie. After the party retrieves the correct key, the Pyro Jacks run off with the treasure to present it to their king. To get back their spoils, the party ventures to the top of the tower to find King Frost sitting on the platform above the bed in the Princess' Bedchamber. Declaring that all possessions belong to him, King Frost decides to smite the party for their insolence. After a harsh struggle combined with the forces of his minion Jack Frosts, the party defeats King Frost and obtains the Ice Crystal.
- Throughout Digital Devil Saga 2, a Jack Frost may enter a battle and ask a series of questions. Answer 100 correctly throughout the game and you'll have the opportunity to fight said Jack Frost in the final dungeon.
- Breakout Mook Character:
- Jack Frost is the protagonist in Jack Bros. He, along with Pyro Jack and Jack the Ripper, have to make it back to the Makai world before midnight.

- Jack Frost returns as the star of Shin Megami Tensei: Synchrocity Prologue, a side story to the Shin Megami Tensei: Strange Journey remake.
- Char Clone: Frost Ace is a Jack Frost who put on a mask in order to avenge... something. His outfit's design is based off of Char's, and the "Ace" in his name comes from this reference, as he's never actually shown piloting anything.
- Cute Little Fangs: Suitable for a mascot, they've got adorable little fangs.
- Drill Sergeant Nasty: Demonee-ho in SMTIV. He barks commands at the player, and calls him a maggot. He even mentions how he'll unscrew Flynn's head and hee-ho down his neck. Makes sense, as he is wearing a military uniform.
- Dub Name Change: Because of space limitations, what was originally Jack Lantern became Pyro Jack outside of Japan.

Jack asks 20 questions per battle, stopping only when the player answers wrong or correctly answers all questions for the round. Should the player correctly answer all 100 questions they win a certificate for answering the 100th question correctly, and a set of Stat-increasing Data. Players will also have the opportunity to fight Jack Frost should all questions are answered correctly in the final dungeon, the third layer of the Sun.

- In Strange Journey and IV, King Frost has the unique skill Cold World, essentially Mabufudyne with an additional 15% chance to One-Hit Kill.

If Demi-Fiend revisits the facility and runs into Black Frost, the latter will force Demi-Fiend to battle him to test out his new powers as the new Great Emperor. He will revert to a normal Jack Frost upon his defeat, and eventually melt. He later returns to join the group if Demi-Fiend visits the Third Kalpa of the Labyrinth of Amala.
- Devil Survivor: In the middle of the week, Midori enlightens a lowly Jack Frost (level 14 Fairy) of the virtues of fighting for love and justice. Near the end of the week, he shows up to defend a bunch of low level demons as Black Frost, a level 47 team leader Demon. And you get to use him in a few routes.
- In the first Raidou Kuzunoha game, in a second playthrough, an NPC will gift you a Bancho cape, which will be promptly stolen by a Jack Frost and taken to local Mad Scientist Dr. Victor to fuse with it. This will turn Jack Frost into Raiho, who will instantly challenge you.
- Strange Journey: A lonely Jack Frost appears in Sector Carina's basement, moping over the loss of his family.

Kresnik and Kudlak
A Krsnik or Kresnik is a Slovenian type of vampire hunter, a shaman whose spirit wanders from the body in the form of an animal. The krsnik turns into an animal at night to fight off the kudlak, his evil vampire antithesis, with the krsnik appearing as a white animal and the kudlak as a black one.
- Anthropomorphic Personification: The Kresnik is the representative of goodness and light and the Kudlak symbolized evil and darkness.

After receiving their weapons, the two will go to the far north of the 1st Floor to battle. If his mission is done then he will inflict great harm to Kudlak, who will retreat. If Kudlak has the Pest Crop he will poison Kresnik, who retreats. If they both have the weapons it will end in a draw.
- The Starscream: Kudlak in Devichil: Light & Dark first worked for the Dark Imperius Azrael only to later betray him to Light Imperius Remiel. Once he gets mistreated by Remiel during one of his temper tantrums does he decide to turn on him as well. Unlike with Azrael he dies in the process.

- Mad Scientist: He loves engaging in fusion and practicing with them, advancing the art of fusion with each experiment just for the love of fusing.
- Monster Compendium: Another one of his usual services.
- Ominous Pipe Organ: Always accompanied by an organ leitmotif, at different tempos and rhythms.
- Took a Level in Kindness: In his first appearances, The Minister had a rather sinister presence but maintained a civil approach towards the players. His latest incarnations however took on the "Mido" moniker, and together with it a gleeful, dorkish attitude.
Oberon and TitaniaThe King and Queen of Fairies from A Midsummer Night's Dream, respectively.
- Abduction Is Love: Titania kidnaps and traps Raidou in Faerie Land to keep him for herself so he can be loved by her in King Abaddon. Agreeing to stay with her is lawful.
- Adipose Rex: Oberon's redesign (notably seen in Soul Hackers and IV) is a fat old king, as opposed to his youthful appearance in most games.
- Brainwashed and Crazy: Both of them, in Nocturne, by Sakahagi. The entire Fairy populace of Yoyogi Park follows.

- The Maze: In Nocturne, she had several Pixies warp intruders back to a certain point if they run into them.
- Tiny Guy, Huge Girl: Oberon is the tiny guy and Titania is the huge girl. Justified because Oberon was cursed as a child and has not grown any larger since.
- Took a Level in Badass: Titania has been a fairly average demon/persona in many games. In Devil Survivor 2, Titania becomes extremely useful when you unlock her, since she has a natural Null Elements (in other words, she can only be affected by status effects, physical attacks, and magic attacks that have pierce; at this point in the game, there are many strong magic demons) that do not take up any skill slots and has fairly high Magic. Fuse her so that she has Null Everything and she could be one of the best demons in the game.
Ose, Flauros, Decarabia, and ForneusFour demons from the Ars Goetia, Ose and Flauros are known for sometimes interacting with each other and the same goes for Decarabia and Forneus.
- Ascended Demon: Ose and Flauros once they go Hallel thanks to Chiaki in Nocturne. The two show up as Hallel again in Shin Megami Tensei IMAGINE.

- Light Is Not Good: The Hallel forms given to them by Chiaki in Shin Megami Tensei: Nocturne, in which they are purified and regain the shape they had before their fall. The two later achieve Hallel status in Shin Megami Tensei: Imagine where they act as Co-Dragons to Satan.
- Odd Friendship: Decarabia and Forneus even have a Fusion Spell named Best Friends in Persona 3.
- Panthera Awesome: Ose and Flauros are bipedal leopards.
- Stealth Pun: Forneus is described as a "sea monster" in the Ars Goetia, Kazuma Kaneko designed him as a manta ray, also known as the "devil fish". Likewise Decarabia is described simply as "a pentagram"; he appears in-game as a starfish with an eye in its center.
Pixie is one of the most frequently appearing demons in the Megami Tensei universe. She is almost always the first demon recruited and helps the protagonist through healing.
- Breakout Mook Character: Stars in a game with Jack Frost and his bros for the Virtual Boy.
- Disk One Nuke: There is a special staff password in Strange Journey that will unlock a Pixie with special starting stats. The resulting Pixie will only be Lv.1, but will have a magic stat of 10 and a luck stat of 99 along with knowing the skills Megidolaon and Mediarahan. * Expy: According to Kaneko's notes, Pixies design was heavily influenced by Cham Huau from Aura Battler Dunbine.
- Fairy Companion: The player occasionally gets them as a Starter Mon.
- Fairy Sexy: She's a very attractive little pixie.
- Fiery Redhead: She has red hair, and some of her appearances give her a spunky personality.
- Gender Bender: Pixie is male in the Devil Children series.
- Give Me Your Inventory Item: In Shin Megami Tensei: Strange Journey, Pixie will issue the first possible EX Mission, The Injured Little Fairy, in which Pixie requests a Bead, which can be obtained as the spoils of the battle against Morax. Accomplishing this mission is rewarded with a Pixie Knife, a melee weapon that can inflict charm. Later, the same Pixie will evolve to High Pixie and begin issuing requests to bring Fairy demons to her so she can create a land for Fairies. However, direct evolution of Pixie to High Pixie in this game is not possible (the only way to do so is through a Special Fusion).
- Leotard of Power: She wears a blue leotard.
- Lethal Joke Character: Pixies can appear randomly in Samsara Tunnels in Digital Devil Saga and can be summoned by Bonus Boss Elizabeth in Persona 3. Both of which know Megidolaon, the latter of which does ten times the maximum health cap for the game.
- Magikarp Power:
- The first demon you get in Nocturne is a Pixie, who wants to get out of the hospital and go to Yoyogi Park. She'll help you out in getting the card needed to get out. After you arrive at one end of Yoyogi Park, she'll try to part ways with you, but if you tell her you need her, she'll stay with you. For Nocturne Maniax, if you take Pixie (or one of her 'descendants') to a certain area of the Fifth Kalpa, she'll turn into a level 80 "super" Pixie.
- Raise a Pixie in Nocturne properly and she'll evolve into High Pixie. Keep her for long enough and you'll get Queen Mab.
- In Majin Tensei II: Spiral Nemesis Pixie is one of the early mons with skills that unlock at Rank 50, if you guessed these (in Pixie's case 'Once More' that let's a unit act twice a round) are some of the rarest and most useful in the whole game you're absolutely right.
- Shock and Awe: Most of her appearances give her the basic Zio skills.
- Starter Mon: She is the first demon you recruit in Nocturne, Strange Journey, and Persona 5.
- Took a Level in Badass: In Persona, she can learn Zionga. Got a decay in Persona 2: Innocent Sin by having that skill removed and then another boost in Eternal Punishment where she can now naturally learn Megido. Another decay in Persona 3, in which she doesn't learn a single offensive spell by natural means. And another boost in Persona 4, in which can naturally learn Zio.
- Video Game Cruelty Potential: After getting the leader Pixie in Shin Megami Tensei IMAGINE, you can choose to give her to Snakeman to create healing salves or you could keep her to get a valuable item.
- White Mage: Many of her appearances give her the basic Dia skills.
Cu Chulainn is an Irish mythological hero who appears in the stories of the Ulster Cycle, as well as in Scottish and Manx folklore. The son of the god Lugh and Deichtine, sister of the king of Ulster, he was originally named Setanta, but gained his better-known name as a child after he killed Culann's fierce guard-dog in self-defense, and offered to take its place until a replacement could be reared.
- Bridal Carry: In Imagine, Cu Chulainn's mount animation has him carry around the player character in his arms.
- Combination Attack: Persona 3: Cu Chulainn, along with Scathach, can use the Shadow Hound Fusion Spell, which inflicts severe Strike damage upon all enemies.
- Dub Name Change: Cu Chulainn is renamed to Lance in the English release of Megami Ibunroku Persona.
- Evolutionary Levels: Cu Chulainn appears as a distinct demon in Shin Megami Tensei III: Nocturne. He cannot be encountered nor recruited by the Demi-fiend, rather, the Demi-fiend can only obtain him by evolving Setanta by reaching at least Lv. 52 himself and completely mastering Setanta's skillset.
- Only Known by Their Nickname: Although the real name is Setanta while Cu Chulainn means "the Hound of Culann" (a title he got after killing Culann's hound and taking its place)
- Our Fairies Are Different: Setanta is part of the Fairy race, which is replaced by Genma upon evolving into Cu Chulainn.
- Palette Swap:
- Tam Lin is basically Cu Chulainn in blue. In fact, Tam Lin has been a recolor of Cu Chulainn since the first Shin Megami Tensei game. Interestingly, Cu Chulainn's old design from Soul Hackers returns in Devil Survivor 2, while Tam Lin uses the recolor of the Nocturne design, thus he and Tam Lin don't share the same, palette-swapped appearance.
- In Majin Tensei II, Diarmuid is a palette swap of Cu Chulainn.
- Side Quest:
- Cu Chulainn appears as a NPC in the EX Mission A formal search request in Strange Journey, in which his mother has traveled to the Schwarzwelt to find him. The trail for him leads first to Sector Bootes, where an Orthrus will indicate he has moved to Sector Antlia to offer support to his old teacher Scathach. Meeting with Scathach will reveal Cu Chulainn has heard of the search and is moving to meet the protagonist. Near the entrance to Sector Antlia, Cu Chulainn will be found with Enemy Search. He will leave for Sector Carina to meet with his mother; once met there, he will reward the protagonist by unlocking Cu Chulainn fusion, giving him Gae Bolg, his spear, and giving him the Knight's Oath, which contains a Demonica code to summon him.
- In IV, Scathach's gotten tired of trying to control his bloodlust, so she transforms him back into Setanta and has Flynn duel him so he can realize how counterproductive it is for him. After a beatdown, he's allowed to regain his full form and his Special Fusion is unlocked.
- "The product of a failed summoning. Bereft of its original powers, it's trapped in an incomplete gel form. Its journey from the Atziluth world to the Assiah world was incomplete in some way."— Compendium info from Shin Megami Tensei: Strange Journey
- Art Shift: Either looks like a typical blob monster or a dissolving skeleton covered in slime depending on the game.
- Joke Character: Especially prevalent in Strange Journey and IV, where they're weak to nearly every type of attack.
- Lethal Joke Character: In Dx 2, one appears as the boss of the 40th floor of the Aura Gate, also making him the penultimate major boss of the dungeon. While he has all the weaknesses of regular Slimes, he also has a boatload of HP to cover for it, as well as Life Drain, Megaton Raid, and two Phys Amps.
- Palette Swap: Has different colored versions of itself as regular enemies.
- Weaksauce Weakness: In the IV duology and Dx 2, in addition to keeping their weakness to all magic except Dark, they're now also weak to basic physical attacks.
- "I extended salvation to you, even thought it meant bending the laws of the universe. That is because I sensed that humans have the potential to exceed the Axiom."— Shin Megami Tensei IV: Apocalypse
Not a demon, but rather, a recurring human throughout the series. He's the wheelchair-bound genius who created and distributed the Demon Summoning Program. He was also the inventor of a teleportation system that inadvertently opened a portal to the underworld, setting off the events of the first game. Bears absolutely no resemblance to Stephen Hawking.
- Action Survivor: He manages to survive through every catastrophe that occurs, which is amazing, considering that he's, well, crippled ... at least he would be this if he was still a normal human.
- Adaptational Attractiveness: Looked more clearly like Stephen Hawking in the first two SMT games, given his posture and facial features, but was changed to look much more youthful, and much less handicapped, by the fourth game.
- Ambiguously Human:
- He has a strange habit of going wherever he pleases, be it a demon's Domain or the Void Between the Worlds. Add to that his shining glasses, the odd echoes in his voice, and the fact he's been alive since Shin Megami Tensei I, a timeline implied to have been erased from existence by the events of the Raidou Kuzunoha duology, and suddenly the good Doctor seems a lot weirder...
- It is explained in IV: Apocalypse that he has transcended his previous state as a human, and has seemingly reached attunement with the Axiom over time as he traveled across the various SMT verses, something that scant few gods have had the chance to do. Right before the heroes fight Stephen, the Hero notes that magnetite/MAG is flowing out of his body as he shows off his true abilities, something that is implied to come as a result of reaching the level of power that Stephen has.
- Ascended Extra: Goes from being a Recurring Extra to a key character of the fourth game's Neutral path.
- Big Good: In short, if you see him, it's quite likely he's orchestrating victory for humanity. In IV: Apocalypse, he's very much your primary supporter on the Neutral path.
- Bonus Boss: Apocalypse finally lets you fight him through DLC. He has apparently grown so powerful that an alliance between the Hero, Aleph, the Demi-fiend, Flynn, and Nanashi is required to beat him.
- Gadgeteer Genius: He created the Demon Summoning Program that forms the basis of the franchise, and in some games regularly updates it as you meet him.
- Genius Cripple: Became crippled after he was attacked by a demon. IV: Apocalypse's Diamond Realm DLC shows that he definitely ISN'T.
- Gondor Calls for Aid: In the first Shin Megami Tensei game, he sent the Demon Summoning Program to as many people as possible before getting captured.
- Gone Horribly Wrong: Testing of his teleportation program randomly managed to rip a hole in reality that filled the world full of demons.
- I Am Not Left-Handed: He proves that he has become so powerful in IV: Apocalypse by getting up from his wheelchair when he fights you in the Diamond Realm DLC.
- I Owe You My Life: The SNES series protagonists would be dead if they didn't have Stephen's Demon Summoning Program.
- Mythology Gag: In Soul Hackers, a New Game+ COMP software is named after him, and it removes the fusion level limit.
- Being based on the views of the real Stephen Hawking, he believes that Gods, even if they exist, are not needed and that humans should rely on their own strength instead.
- Up to the point that he interferes only a bare minimum with Dagda's plans in Shin Megami Tensei IV: Apocalypse, because of their common goals, despise them culminating in destroying and remaking the world. For comparison, any other game where the player showed any kind of affinity towards an evil goal, he either dropped all contacts with them or openly showed hostility. In the same calm voice tone from always.
- Pro-Human Transhuman: He clearly has become something more than human by this point and he generally believes that humans should not need to rely on gods and therefore represents a humanistic Neutral view that rejected the esoteric, supernatural outcomes of Law and Chaos. This is apparently based on the real Stephen Hawking on how he doesn't reject gods, but rather view them as unnecessary.
- Recurring Extra: Through the main series Shin Megami Tensei games, with the exception of Nocturne.
- Restraining Bolt: Turns out, his wheelchair serves as this. When you face him as a Bonus Boss in the DLC of Apocalypse, standing up from it makes him just as powerful, if not more so than YHVH!
- Sharp-Dressed Man:
- Underestimating Badassery: Fighting against him as ultimate boss of IV: Apocalypse makes this much more obvious, as it takes all five mainline SMT protagonists to merely prove their strength and resolve against him in battle. It is especially telling how powerful he has become, given how he shares many moves and even a Leitmotif with YHVH.
- Unwitting Instigator of Doom: The first one to open the gate to the Abyss and set off the events of the franchise.
- Vocal Dissonance: Always speaks in a soft, calm tone, and occasionally is even a Terse Talker. It becomes very disturbing to hear what he says in this tone in the darker parts of IV: Apocalypse.
Taira No MasakadoA feudal Japanese warlord, one of the few true historical figures in the series. Masakado was a samurai during the Heian period and hatched a plan to conquer most of the Kanto region. While he was slain, his influence was so strong his head was sent to Kyoto and later Edo, where it was set in a special shrine. To this day he is considered a demigod of sorts, and it is said condition of his shrine dictates the city's fortune. Due to his fervant loyalty to his country and faith in humanity in general, he is widely considered to be the closest thing the series has to a Neutral representative.
- Ascend to a Higher Plane of Existence: Not in game, but historically. From rebel samurai to protector deity of Tokyo, not bad at all.
- Badass Normal: How else could a samurai lead the Four Heavenly Kings?
- Balance Between Good and Evil: He must reside in balance and should either one overcome the other inside him he will go berserk. The bad luck and misfortune in the capital in Raidou Kuzunoha vs. King Abaddon allowed his rage to possess his body, leaving his rational half to leave his body to find Raidou Kuzunoha. In Shin Megami Tensei IV his balance going out of whack leads to the final DLC battle against him in order to calm him down.
- Big Damn Heroes: If Masakado is restored in Shin Megami Tensei II, he will help in banishing the guards around Castle Kether in the Neutral Alignment.
- Bonus Boss:
- One of the two ultimate bosses of the game alongside Lucifer in Raidou Kuzunoha vs. King Abaddon. He can only be fought on New Game+, 99% completion of all case file at least once which requires beating the chaos route and facing the New Game+ ones given by Lucifer, and talking to a man outside the Narumi Detective Agency to get the case file. He can be found on the 999th floor of the confinement chamber and will be joined by an "imposter" Masakados who acts as a Mag Drain Battery but are not infinite in number. After bringing his HP down to zero Raidou must negotiate with him to end the battle. The reward for beating him is the material needed for the ultimate sword Masakados and the ability to fuse Masakados.
- In IV's final DLC quest he goes berserk as an ICBM is looming in the horizon over Tokyo. He wanted to cover the entire city with his body, but lost control of his power and had to be woken. He, quite simply, requires the Pierce DLC skills, as he flat-out drains everything. Except Light, Dark and Almighty. Light and Dark he nulls, and Almighty is a complete joke against him. To add insult to injury, he wastes many of his six turns in moves that don't do anything like Move Slowly, Aim Carefully, Clench Fist and Prayer. Then he breaks out Curse Thy Enemy and Guardian's Eye. He has double the amount of raw HP of one Lucifer's forms or more than four times the HP of Merkabah's first form and almost three times as his second form. Oh, and you only have ten turns to defeat him.
- Came Back Wrong: When you resurrect him in Shin Megami Tensei II, he will be nothing but an animated corpse until Hiruko gives you the final part needed - Masakado's soul.
- Continuity Nod: To summon him, an item known as Masakados is almost always needed.
- Emotion Eater: A rare semi-heroic example on the Neutral Path of IV. He devours the emotions of Hope, Goodwill, and Spite in order to regain his strength.
- Evil Makes You Ugly: His anger possessing his body in Raidou Kuzunoha vs. King Abaddon turns him into the bald form he had when he Came Back Wrong in II.
- God in Human Form: The protagonist from the OVA Tokyo Revelation is the reincarnation of Masakado.
- Gotta Catch 'Em All:
- In Shin Megami Tensei II, his servant, Hiruko, will reveal Masakado was slain some time earlier. So he asks Aleph to gather the pieces of his corpse so he can be brought back to life.
- In Shin Megami Tensei III: Nocturne, should the Demi-fiend gather all twenty-four Magatama, the priest at the Cathedral of Shadows will give him the Lord's Blade, allowing him to reach the Bandou Shrine and confront the Four Heavenly Kings, his servants, for the right of a single conversation with Masakado.
- When awakened in IV's Neutral Path, he's lost access to his physical form that became the dome and thus the source of most of his powers. So he must devour the three Great Spirits as a substitute so he can remove the Firmament above Tokyo to restore everything to normal. He needs Flynn to recreate the Great Spirit of Hope by taking on missions to restore Tokyo's citizens' hope, and to retake the Great Spirits of Goodwill and Spite by taking them from the entities who have absorbed them - Merkabah and Lucifer, after they interfere with his first attempt to remove the firmament when he devoured the Great Spirit of Hope.
- Guardian Entity: For Tokyo. He's had his ups and his downs.
- Infinity +1 Sword: If he appears as a fusable demon or his name appears on a piece of equipment, you can damn well bet that there will be some difficult requirements and a lot of power attached:
