Fan Works / Burn The Witch

Warning: As a potential Death Trope for successful examples, many unmarked spoilers are ahead.

The Doctor Who/Star Trek: Enterprise fanfic A Fair Cop portrays Star Trek's No Transhumanism Allowed as this, which is bad news for the Doctor's genetically enhanced companion Zoë Herriot.

In Shadow of the Dragon, Takashi tells a story about witch burnings and trials... which obviously makes Sakura uncomfortable. As a result, Chiharu mistakenly believes that he too has found out about Sakura's magic and chews him out for scaring her, only to discover that he was merely telling a story that Eriol informed him of back in elementary school and end up blowing the masquerade to him herself.

In Destiny (Afterandalasia), Frollo successfully burns Esmeralda after he falsely accuses her of witchcraft. The entirety of the film is her Dying Dream.

They Burn Witches, Don't They? is an Alternate Universe fic set in the Middle Ages. The titular witch-burning involves the fire, a torturous Inquisition, and an angry mob.

Several fics such as A Brand Plucked Out of the Burning feature America being victimized by the Puritan moral panic about witches when he accidentally reveals some inhuman characteristics, but it's mostly historically accurate as he's hanged — even if he's physically a child. Fanon enjoys making this the reason why he Does Not Like Magic in the modern era.

In one fanfic set in a medieval AU, Jade Harley is almost burned at the stake, despite her insistence that she's a "good witch". Fortunately, Dave Strider (a knight) manages to convince the townspeople to let her go.

In Witch Hunt an alternate universe set in Puritan times, Gaz is accused of being a witch and performing evil magic against her neighbors. Although she is highly unpleasant and anti-social, her brother Dib knows she is not a witch and tries his best to defend her. Her only defense is to sneer that she's not a witch and call everyone idiots for believing in them. She eventually gets burned at the stake.
Similarly, in Witching Hour, set in Medieval times, Gaz becomes suspected of being a witch after a series of strange events happen around her all arranged by Zim. The final nail in her coffin is when she's found in the woods surrounded by ritualistically slaughtered animals, covered in their blood; after this, she's seized, put through a Kangaroo Court, and finally burned at the stake.

Appropriately featured in BURN THE WITCH:
- After learning the hard way that Lila is a Con Artist, Rose gets akumatized into Witch Hunter, who uses her powers to whip up everyone who hears her listing out Lila's myriad crimes into a Medieval mob frenzy. Much of the drama revolves around Marinette trying to ensure Lila doesn't meet such a painful demise, despite Lila actively working against her best efforts.
- Tikki's past is also touched upon; as canon established that Joan of Arc was one of her previous Ladybugs. As far as Tikki is concerned, the fact that she couldn't save her from being accused of witchcraft and burned at the stake was one of her deepest regrets.
Soulmate Survey: After finding out that her crush and idol Adrien Agreste was matched up with another girl on the highly-acclaimed and scientifically accurate dating app Soulmate Searcher, Vivienne (who changed her name to Adrienne out of her obsession with him) is akumatized into Fandoom, who plans to burn Marinette at the stake for getting perfect compatibility with him.

In Mutant, Kittery Abigail is called a witch, and the mob is glad when she was killed by stray bullets when a member Shot The Lock.

Chasing Dragons: During the height of the Upper Mander Rebellion, Septon Ryman's radical faction of the Faith starts burning those they deem heretics (which is basically all prominent nobles who refuse to convert to their teachings).

In I'm a doctor, not a freaking marshmallow!, Dr McCoy ends up in this situation after a landing party goes wrong and he is captured by the primitive planet's natives. Unfortunately, Prime Directive means they can't just beam him out...

In Breaking Boundaries, Koko seems to really want the witch hunt to happen and constantly does whatever he can to 'find' a witch and get them hung or burned. Ironically, he is the witch.
