History Characters / ShinMegamitensei

** Jack Frost returns as the star of ''Shin Megami Tensei: Synchrocity Prologue'', a side story to the ''Shin Megami Tensei: Strange Journey'' remake.

* DubNameChange: Because of space limitations, what was originally Jack Lantern became Pyro Jack outside of Japan. Jack Ripper was likewise changed to Jack Skelton in the English release of ''Jack Bros.'', though that may have been to remove connections to a real-life serial killer in a [[BleachedUnderpants kids' game]].

* DropTheHammer: As you would expect of Thor, he wields the hammer Mjolnir.

* BonusBoss: In ''NINE'', Susano-o can be fought in Chapter 5, after defeating all five fighters in Akiba Arena.

* BonusBoss:
** Kazfiel was an optional boss fight in ''Shin Megami Tensei I''.
** In ''Strange Journey'', both Aniel and Kazfiel were optional boss fights in the three EX Missions ''Before The Holy Battle''. The third one being a DualBoss against the two. Samael also appears, but is more of a random boss due to the mechanics of finding hidden demons in the game.
** In ''IV'' Kazfiel is a boss faced in the Challenge Quest "Escorting Your Comrade", where he is the last angel preventing you from helping [[spoiler:Navarre]] escape from Mikado.

* BonusBoss:
** Nebiros appears as one in ''VideoGame/DevilSurvivor: Overclocked''. Having come to test the protagonist at the request of his master.
** [[spoiler:In ''Devil Survivor 2'', both of them have their own separate battles and join Alice in the BonusBoss battle against her.]]
** [[spoiler:In ''Strange Journey Redux'', both of them, along with Beelzebub and Lucifuge, spawn separately on the lower floor of the new final dungeon on a New Game Plus, and each alone are stronger than anything else in the game. Belial guards the Lucifer Sword, which comes with a passive Pierce when using it, and Nebiros has the Lucifer Gun, which has a move that guarantees critical hits.]]

* {{Necromancer}}: In Nebiros's BonusBoss battle in ''VideoGame/DevilSurvivor2,'' he spawns a bunch of undead demons as EliteMooks. [[spoiler:If his turn comes around and even a single enemy team has been destroyed, he'll revive every enemy team. If you destroy him, he will BodySurf into one of his Mooks and turn it into a new Nebiros. To win, it's necessary to destroy every single team, including Nebiros's, in a single turn.]]

* BonusBoss: After the party has reached the top floor of the final dungeon in ''VideoGame/DigitalDevilSaga'' 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.

* BonusBoss:
** 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 ''VideoGame/DigitalDevilSaga'', 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.

* LethalJokeCharacter: Pixies can appear randomly in Samsara Tunnels in ''Digital Devil Saga'' and can be summoned by BonusBoss Elizabeth in Persona 3. Both of which know Megidolaon, the latter of which does ten times the maximum health cap for the game.

* VoiceForTheVoiceless: Since the Demi-Fiend retains his qualities as a HeroicMime even as a BonusBoss in ''Shin Megami Tensei V'', it's Pixie who does the talking for him.

* RestrainingBolt: Turns out, [[spoiler:his ''wheelchair'' serves as this. When you face him as a BonusBoss in the [=DLC=] of ''Apocalypse'', standing up from it makes him just as powerful, if not more so than ''[[{{God}} YHVH]]! '']]

** [[spoiler:Given [[BonusBoss what happens with him]] in IV: Apocalypse's Diamond Realm DLC, this also counts as BadassInANiceSuit.]]

* UnderestimatingBadassery: [[spoiler:Fighting against him as [[BonusBoss 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 [[{{God}} YHVH]].]]

** In ''VideoGame/ShinMegamiTenseiIV'', Masakado joins you if you take the Neutral route, but he's pretty so-so as a combatant, subverting this trope. Double subverted when you unlock Masakado's ''Shadow'' as a reward for defeating him in his brutally hard DLC BonusBoss fight, as he gains some extremely powerful abilities, such as one that not only does Almighty damage but ''constitutes a weakness hit'', resulting in extra turns and a possible Smirk for him no matter who it hits.

* BonusBoss: Infamous for being an entire race of them, with Matador in ''Nocturne'' being the sole straight mainline exception.

** ''King Abaddon'' also has the [[JustForPun 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.
