History Characters / FiendFolio

* PuppeteerParasite: The tumor on Mr. Dead's head appears to be in complete control of the body.

[[folder:Tainted Fiend, the Bastard]]

* ArcSymbol: Rorschach tests, they appear as her boss icon, her bestiary icon, and if you die to it, Isaac's Last Will gets replaced with one.

* BlackAndRedAndEvilAllOver: She's a Gehenna boss, did you expect anything different?

* {{Dominatrix}}: Madomme herself, who controls all of the other minions, and is a living leather suit. Even Champ, the "king", is kept locked in a cage for no reason other than Madomme's amusement (Champ at least seems okay with this arrangement).

* HellBentForLeather: Exaggerated; Madomme is a ''sentient, demonic dom suit''. Played straight with all of the bitches, who only ''wear'' leather gear instead of ''being'' leather gear.

* ShoutOut: Some of the hats given by Birthright include [[{{VideoGame/Pikmin}} Captain Olimar's helmet, a flower]], [[Franchise/SuperMarioBros Mario's hat]] (but with an "F" in place of the "M"), [[VideoGame/TeamFortress2 the Ghastly Gibus, the Tyrant's Helm]], and a pair of [[WesternAnimation/DespicableMe googly-eyed goggles]].

* ShoutOut: To ''{{Film/Ghostbusters}}''.

A LivingStatue who focuses on collecting and smelting trinkets, with the twist that all trinkets are replaced with rock trinkets unique to Golem. By entering the Subway, he can pay one and a half Soul Hearts to permanently gain the effect of a trinket, spend coins to grind a trinket into a different trinket, or give unwanted trinkets by crushing them into Soul Hearts. Golem's rock trinkets come in three forms: Normal rocks that merely act like normal trinkets; Geodes, which give a greater bonus if Golem's other trinket slot is another geode; and Fossils, which have unique effects when crushed.\\

Golem's Birthright effect gives him +2 Luck and causes tinted rocks to drop rock trinkets in lieu of Soul Hearts.

Fiend's girlfriend. China is a genetically-modified apple who is only available in the Handle With Care challenge or if the player dies with the Cursed Urn trinket. Much like the Lost, China has no hearts. Instead, when China takes damage, she instead gains a Broken Heart. The twist is that China is also incredibly fragile and takes damage if she so much as brushes up against a solid object.\\

China has a 15% chance to find a Horse Push-Pop after clearing a room, which will remove one of her broken hearts. Additionally, she has a 20% smaller hitbox and has an innate .75x tear delay multiplier.\\

* ObviousRulePatch: To accomodate China not being able to press up against objects without taking damage, she's able to interact with doors and key blocks from a short distance away.

A humanoid frog only available in the Frog Mode challenge, or if the player dies while holding the Frog Puppet or Tattered Frog Puppet trinkets. Slippy's gimmick is that she is constantly on the move. If the player stops inputting movement, Slippy will [[MeaningfulName slip]] in the last direction she moved. The only way for Slippy to stand still is to use her Golden Frog Head active item, which will cause her to stop moving while its attack charges.\\

* AlmightyJanitor: Averted. He's literally a janitor, but he's not good at anything else

* TheStoner: He is heavily associated with weed, is Fiend's weed supplier, and starts with the [[MushroomSamba Wavy Cap]] item in his pocket slot

* DungFu: Obviously.
* FatBastard
* {{Gasshole}}

A BlobMonster made entirely of water.

* KillItWithWater

* ShoutOut: The tapeworms are based on ''Tapeworm'', a board game made by Edmund [=McMillen=].

* TalkingPoo

* FacelessEye

* BulletHell: Some room layouts feature this.

* TheWallsHaveEyes: And they shoot at you.

Fiend corrupted and tainted by the horrors in the basement. His body has degraded into black sludge. The Bastard is a character focused on the DoppelgangerAttack.

The Bastard gains one mini-copy per full heart in his health bar, but is only able to hold a maximum of six hearts.\\
