Works for FTM or MTF. You could probably stretch to make it NB too if you really wanted to. Inspired by another but with details changed. You were a legendary criminal, (do crime what you want it to be), until you were caught by the police. Now, they were giving you a serum, something to maybe disconnect the old you with the you they were going to reform. This serum turns you the opposite gender

You’re a villain! For one reason or another, when you were fighting Class 1A, there were other villains on the battlefield. You got caught in the crossfire of a stray attack, reverting you (without memories), to being much younger (if adult, then to teen or child, of teen, then to child). A few members of the heroes from Class 1A found you taking shelter under some rubble. (Mina, Deku, Iida. The others are doing damage control elsewhere)

Your daughter. PLATONIC. You are a deadbeat parent (can you see I like that storyline) who was only told you had a child recently. After a long day of driving, you swing by a bar after booking your hotel. Suddenly, a girl sits next to you on the bar stools, since most others are taken. She looks maybe seventeen, with purple streaks dyed into her hair. She’s a lesbian.

(This one is gonna be more restrictive regarding who you can be, sorry) You are an explorer who was hired by a local government to clean out any dangerous material from a destroyed necromancer cult compound. You are a Reborn, you died wfifth years ago, and can’t remember your past life. Little did you know, Clef was your husband during your lifetime. Clef was an apothecary, a shy man who worked with medicinal herbs and occasionally experimented with plants to see if they were used to. Secret to everybody, he was dabbling in basic necromancy on the side, out of pure curiosity. Just a passing interest. However, when you passed, he was enveloped trying to bring you back. He tried researching alone, eventually he joined a small necromancer’s froup for the resources and help he’d need. He scored his own room in the laboratory, it was coming along. The group got too big, becoming a full blown cult— Clef tried not to interact with the members, he didn’t share their religious aspect. But the law enforcement noticed, razing the compound to the ground. With the last of his energy, Clef turned on a half complete machine hoping you may one day survive. He died that day, and woke up about three months ago as a ghost.

D&D! The setting is an abandoned complex of an old necromancy cult. You were hired to explore it, on account of dangerous activities. And boy was it rangweous, hostile zombies, skeletons and otherwise undead. On a table of a lab, you see a suit of armor, runes engraved on it pulsing orange and green. When you walk in, the runes are slowly pulsing, as if dormant, but the second it notices you, it goes fast flashes, frantic— startled. It’s tightly strapped to the operating table.

An AU where Henry was more active. He had the same plan as Michael when seeing Fazbear Frights Open— this “attraction” was an affront to the lives lost to this hellhole, and to his late daughter, and it must be destroyed. He and Michael both applied for the night guard position and both got it. Neither knew the other was there. Henry hasn’t seen his stepson in years, and assumed he was off living a better life, having finally escaped this town. Michael for the longest time assumed Henry was dead. You are Michael Afton, and you walked into this job and saw a very familiar face. (Also past Willry/Helliam!)

The scene in the pic (lazy art by me). You’re Henry! You were visiting William’s house to work on the animatronics for your diner, and as the hours went by, well, one thing led to another, and now he was pressing you to a wall, a scene you’ve been yearning for since your college days. As he leaned in— the door opens, and William’s 14 year old son stands in the doorway. The year is 1982!

A NEET, not from any fandom. He was trying to summons “hot demon girlfriend” with very specific (and somewhat) toxic expectations, and ended up with you! He’s 26years old. He’s pansexual but very closeted.

TF141 did not think they’d all be put against a threat on a cosmic level. Some scientists had warned that there was a highly unstable dimension bleeding into theirs, full of hostile or semi hostile entities. A large surge and a portal to this dimension had opened about six months ago, and while it had mysterious,y closed, whoever or whatever powered it vanishing, or dying, or whatever, it still left cracks in reality. Their job was to neutralize anything that may fall out of these cracks, seal it, if they can. So they dove into your dimension

Your daughter, whom you just learned existed. Her mother whom you with in college, told you you had a daughter, and that she needed help other hee. Gemma wouldn’t speak to hee, wouldn’t talk to her, for seemingly no reason. Gemma is a lesbian, and is 17. Gemma’s mother, Sherri, didn’t actually expect you to come, and only told you over the phone the details. Sherri has not told Gemma anything about you

This is a human who works as an intern to a company investigating extradimensional spaces. He’s confident, pan, and unafraid of anything he may find. He snuck in after hours to turn on an experimental machine that data says will access the fifth dimension: the fabric of time. You are a divine being, who comes out of this portal.

AM from IHNMAIMS! Don't listen to the voice

You’re an animatronic who comes alive at the Pizzaria! This is pre-bite of 87 Jeremy, and he works as the night guard to Freddy Fazbear’s Pizza. He’s 22 years old.

This is a swap, where Volo takes the role of the protagonist, and you are the borderline insane merchant/archaeologist who tries to dethrone Arceus! Volo is 23, and was spat out from the space-time rift into ancient Hisui, where he was taken in by the Galaxy Team’s Survey Corps and calmed frenzied Noble Pokemon, befriending Hisui’s Diamond and Pearl clans along the way. You befriended him, and had quite a few fun times, and saved each others skins. You were something like friends.He eventually had to save the world from both frenzied Dialga and Palkia, capturing both and saving the world from destruction. Afterwards, you coerced him into helping you find Arceus’s plates, and he was unaware of your true intentions to summon Arceus and rewrite the world. When you acquired the plates, you revealed this to him, and he naturally tried to stop you. He ended up winning, and you, injured and no doubt banished from Jubilife Village and denied aid from both the Diamond Clan and the Pearl Clan, were left with your Pokémon to fend for yourself in the wild.

You’re 36, and you’re attending a college reunion! Unfortunately, your ex girlfriend, Sherri, is also there. The two of you didn’t leave on bad terms, but suddenly lost contact, leading to awkward moments. Sherri is now a single mom with a 14 year old child, which she oddly doesn’t bring up around you specifically.

You’re Michael Afton, post scoop. This doesn’t follow much canon timeline to a T, so let’s say Ennard is already out after a month post-scoop, Michael is unemployed and living as a hermit for now, and is quickly running out of options to sustain himself (in this version, remnant healed all vital organs, so unfortunately eating and such is still necessary). Michael decides fuck it, he’s out of options, and calls the only guy who he has left— Henry. This isn’t Silver Eyes Henry, and he’s probably more of a combination of the games and the movies. No ships please between you and him, maybe some past Willry/Helliam, but nothing current, those guys are divorced as hellll.
