History Characters / ReverieTouhouCombinations

* TheLastOfTheseIsNotLikeTheOthers: Whereas the other bosses are themed after characters from ''Touhou Project''[[note]]Or in Kogasa's or Doremy's cases, are straight-up Touhou characters[[/note]], Guppet is an outlier for not being based on a specific character in ''Touhou''.

* BossRush: The revamped version of her boss fight can be best described as Mega Satan on crack. Her spell cards now incorporate attacks from ''every other final boss in the game'' (which includes the likes of Mega Satan, Mother, and even ''Delirium''). Hope you found a Wafer!

* TheLastOfTheseIsNotLikeTheOthers: The new alt-path bosses are very much in-line with the other ''Isaac'' enemies and only loosely based on ''Touhou'' characters… except for Kogasa, who appears as herself with little-to-no changes to her design.

* SequenceBreaking: While you'd typically fight this instead of Hush, you can still teleport out of the room if you have the means to do so (0 - The Fool, Teleport!, etc.), not unlike with Mom. So if you can get back to Womb II's boss room within 30 minutes of the current run[[note]]Or if you have Mama Mega or the Strange Key trinket[[/note]], it is entirely possible to fight both Reverie Music and Hush in one run.

!!Eika

!!Tainted Eika
Eika depicted as a bloody fetus. She starts with Fetus Blood as a pocket active, which allows her to spawn unique Blood Bony's once per floor. She can only have red hearts but can still collect Soul, Evil, and Bone hearts to summon her own friendly Bonies, with the former two upgrade-able upon collecting more.\\\

Her Birthright effect makes her Blood Bonys explode upon forcibly respawning from her Fetus Blood active.
----
* BloodyMurder: Blood Bony's, summoned via Fetus Blood. [[TheMinionMaster who fight for Eika]].
* DeathOfAChild: This incarnation of Eika takes her core concept, being a spirit of a miscarried child, and takes it to its logical conclusion by making her a bloody fetus.
* DemBones: Each of her summons are Bony's of differing abilities and characteristics.
* UndeadChild: Even moreso than her regular counterpart. Here, she is effectively a DistaffCounterpart to ???, with her inability to gain any health other than red hearts being an inversion to ???'s inability to gain red hearts, and her physical appearance and monster-summoning powers also drawing parallels to Hush.

!!Satori

!!Tainted Satori
Satori... but she's in a wheelchair. Her wheelchair makes her start slow, but she gradually gains speed while moving. At high enough speed, she becomes hazardous to the foe, [[CarFu running them over or damaging them]] as long as her speed is not negated.\\\

She also starts with a pocket active item called Transfuse, which deals half-a-heart of damage to temporarily increase her speed and damage stats, similarly to the IV Bag.

Her Birthright effect results in her charging attacks causing an explosion upon collision with an enemy at charging speeds.
----
* CarFu: Her playstyle mainly revolves around building up enough speed to run over every enemy in her path.
* HandicappedBadass: Being in a wheelchair doesn't stop her from slaughtering any enemies in her path. If anything, it makes her more dangerous than if she decided to just use her tears exclusively.

!!Seija

!!Tainted Seija
Seija trapped in mediocrity. While she still has the same "Weak is Stronger, Strong is Weaker" gimmick like her non-tainted counterpart, all item pedestals now exclusively spawn items at quality level 2. Her pocket active D Siphon can either re-roll items to a lower or higher quality, depending on the number of rerolled item pedestals beforehand.\\\

Her Birthright effect allows for her to better control the D Siphon's ability to raise or lower item qualities; reducing the quality by default, while increasing the quality by holding down the drop button while using it.
----
* DifficultButAwesome: Because of the items' quality being set in stone whenever they spawn, she's stuck [[MasterOfNone without any items that drastically affect her build]], and the only way to get lower or higher quality items is through careful and efficient use of her pocket active. But because of said pocket active, she can effectively get any item quality with efficient use -- the {{Balance Buff}}ed quality 0 items which are obtained in two rolls, and the (generally) more valuable 3 or 4 qualities that are earned with sufficient siphoning. The latter qualities are still particularly risky due to Seija's gimmick, making it a toss-up to whether or not they'd be a worthwhile grab.

!!Hourai

!!Tainted Hourai
Hourai, but half of her face is replaced with bloody flesh. This character is only accessible by touching the Hourai doll after attacking it to turn it into a Tainted Hourai doll.\\\

Whereas Hourai's corruption revolves around her dying in many different ways, Tainted Hourai's revolves around her killing enemies in different ways, with a reward spawning with her on the next floor depending on how many ways she killed her enemies. Her Birthright makes non-boss enemies immune to damage from a triggered kill type when they take damage from a kill type that hasn't been triggered yet.

----
* DifficultButAwesome: While getting all 8 of the kill types triggered per floor is tricky, getting most of them nets you some powerful rewards. Getting at least 3 will net you a random item, 4 nets you an Ultra Secret Room item, 5 nets you a Devil Item, 6 and 7 increase the number of devil room items. And if you get all 8, You get a '''[[InfinityPlusOneSword Death Certificate.]]'''

!Bosses
!!Normal
[[folder:The Abandoned]]
The cheery forgotten umbrella, Kogasa Tatara. Fought in Downpour.

* InvisibilityFlicker: Only the {{Karakasa}} umbrella that she holds is seen normally, with the exception of her taking damage and fleeing the boss room, depicting her silhouette as a solid white light.
* TheLastOfTheseIsNotLikeTheOthers: The new alt-path bosses are very much in-line with the other ''Isaac'' enemies and only loosely based on ''Touhou'' characters… except for Kogasa, who appears as herself with little-to-no changes to her design.
* ScrewThisImOuttaHere: Upon depleting her health, she briefly trips over herself, before grabbing her Umbrella and fleeing the area, but not before leaving the writing of "Boo!" in the corner of the room.

[[folder:Necrospyder]]
Giant fungus-infected spider, based on Yamame Kurodani. Fought in Dross.

* FesteringFungus: The spider has mushrooms growing from the top of its head and one eye, with the implication that it is taken over by a ''Cordyceps''-style fungus.

[[folder:The Centipede]]
Rock-burrowing ''oomukade'', based on Momoyo Himemushi. Fought in the Mines.

* CurrencyCuisine: If there are pennies in the very room it's in (of which there will be when it spawns), it'll rush over to devour the money and restore any health lost, though thankfully it won't [[TurnsRed speed up]] like Ultra Greed does.
* SegmentedSerpent: Each of The Centipede's segments have their own health bar, with it becoming shorter and shorter each time one of them is taken out.

[[folder:Pyroplume]]
A phoenix, loosely based on Fujiwara no Mokou. Fought in the Ashpit.

* AutoRevive: It has hilariously low HP for a boss, but makes up for that by resurrecting itself twice.
* PlayingWithFire: It's a phoenix, so most of its attacks are fire-based.

[[folder:The Summoner & The Immortal]]
A {{necromancer}} and their invulnerable mummy minion, based on Seiga Kaku and Yoshika Miyako, respectively. Fought in the Mausoleum.

* InvincibleMinorMinion: The Immortal is completely immune to damage, and is only properly beaten by defeating the Summoner themselves.

[[folder:Devilcrow]]
A birdlike machine with the power of nuclear fusion, based on Utusho Reiuji. Fought in Gehenna.

* ActionBomb: Upon having its health depleted, it'll unleash a massive, room-encompassing explosion that'll hurt Isaac if he doesn't take shelter behind the corner pillars.
* OneHitKill: Staying in the radiation beam for too long will kill Isaac, regardless of how much health he's got.
* SchmuckBait: The radiation beam also covers what would be a glaringly large blind spot in Devilcrow's attack pattern, which may lead a new player who's unaware of the gimmick to hang out there (oh, look, a safe spot highlighted with a spotlight), oblivious to the significance of Isaac glowing green and rapidly beeping until he abruptly keels over.

[[folder:Guppet]]
The remains of Isaac's pet turned into a marionette. Possibly based on Alice Margatroid and/or Medicine Melancholy. Fought in the Corpse.

* TheLastOfTheseIsNotLikeTheOthers: Whereas the other bosses are themed after characters from ''Touhou Project''[[note]]Or in Kogasa's or Doremy's cases, are straight-up Touhou characters[[/note]], Guppet is an outlier for not being based on a specific character in ''Touhou''.
* PunnyName: A mix of Guppy and Puppet, fitting for Isaac's pet turned into a puppet.

!!Secret Bosses (spoilers)
[[folder:Doremy]]
Doremy Sweet, the {{Baku}} and ruler of the Dream World. Upon collecting the Dream Soul in the Ascent, she replaces Dogma and the Mother Beast as the TrueFinalBoss.

* BattleThemeMusic: The theme that plays for her boss battle is the stage theme for ''[[VideoGame/TouhouKanjudenLegacyOfLunaticKingdom Legacy of Lunatic Kingdom]]'', "A World of Nightmares Never Seen Before". Before the overhaul, she had her battle theme from the same game, "Eternal Spring Dream".
* BossRush: The revamped version of her boss fight can be best described as Mega Satan on crack. Her spell cards now incorporate attacks from ''every other final boss in the game'' (which includes the likes of Mega Satan, Mother, and even ''Delirium''). Hope you found a Wafer!
* DreamWeaver: Doremy, naturally as the {{Baku}} youkai, can manipulate dreams. In the secret boss fight, she appears to Isaac in his DyingDream to avert his fate.
* TrueFinalBoss: Doremy continues the SerialEscalation of this trope, this time being the FinalExamBoss of all prior Final Bosses.

[[folder:Reverie Music]]
A series of sentient music notes representing various ''Touhou'' characters. Upon meeting its requirements[[note]]Picking up its item in Basement I after hearing at least 5 songs, hearing at least 15 songs total, defeating Mom's Heart or It Lives, and then standing on the snowglobe that spawns immediately afterwards[[/note]], it effectively replaces Hush as the very difficult {{Superboss}} for the run.

* BattleThemeMusic: Its theme song is "[[https://www.youtube.com/watch?v=ge71HoKN_0s Illusionary Joururi]]", shared with the Tsukumo sisters.
* ItemDropMechanic: Each phase drops an item from a certain pool when the fight is completely done[[note]]Hecatia drops a Planetarium item, Reimu and Marisa drop a Treasure Room item, Wakasagihime, Kagerou, and Sekibanki drop a Secret Room item, Flandre drops a Devil Room item, and the Prismriver and Tsukumo sisters drop an Angel Room item[[/note]]. Additionally, just like with Hush, a portal to The Void is guaranteed to spawn here alongide Sheol and Cathedral.
* MusicalAssassin: Inverted, as its literal music notes that fight like their respective ''Touhou'' counterpart. Played Straight with the Prismriver Sisters' and Tsukumo Sisters' counterparts, who canonically fight with danmaku music notes.
* MythologyGag: Marisa's counterpart exclusively uses two spells taken straight from ''Imperishable Night'': Earthlight Ray, and of course, her signature [[WaveMotionGun Master Spark]].
* SequenceBreaking: While you'd typically fight this instead of Hush, you can still teleport out of the room if you have the means to do so (0 - The Fool, Teleport!, etc.), not unlike with Mom. So if you can get back to Womb II's boss room within 30 minutes of the current run[[note]]Or if you have Mama Mega or the Strange Key trinket[[/note]], it is entirely possible to fight both Reverie Music and Hush in one run.
* SequentialBoss: It has five phases, each with their own health bars and unique BulletHell attack patterns.

* FeedItWithFire: Cursed Blood, which normally turns damage from fire and explosions into a OneHitKill, instead makes explosions heal her.

A machine with the power of nuclear fusion, based on Utusho Reiuji. Fought in Gehenna.

* InvincibleMinorEnemy: The Immortal is completely immune to damage, and is only properly beaten by defeating the Summoner themselves.

* CurrencyCuisine: If there are pennies in the very room it's in (of which there will be when it spawns), it'll rush over to devour the money and restore any health lost.

* BattleThemeMusic: The theme that plays for her boss battle is the stage theme for ''VideoGame/LegacyOfLunaticKingdom'', "A World Of Nightmares Never Seen Before." Before the overhaul, she had her battle theme from the same game, "Eternal Spring Dream."

[[/folder]]

* {{Nerf}}: My Reflection originally made her tears inflict constant damage for as long as it overlaps with a foe, but has since been reduced to just visually changing the tears into shurikens.
