Well, perhaps in this fanfiction, the quirks in the BNHA world start to have an unexpected effect on the Afton family. Freddy Fazbear could gain a quirk that makes him able to control people's minds, similar to some of the mind - control quirks in BNHA. The Afton family then uses this newfound power to try and create chaos in the BNHA world. And the BNHA characters have to figure out how to stop them while also dealing with their own internal conflicts and challenges.
Definitely Izuku and William Afton. Izuku is all about heroism and saving people, while William is a devious and manipulative character. Their interactions would be full of tension as Izuku tries to understand William's motives and stop him from causing harm. Another interesting pair could be Bakugo and one of the Afton kids. Bakugo's brash and explosive personality would clash with the more mysterious and potentially menacing nature of the Afton kid.
Well, it could be a really wild plot. Maybe the Afton family members from their own dark and creepy world encounter various Creepypasta characters. There could be a battle of who's scarier or they might team up for some strange and evil purpose. For example, the Afton family's murderous tendencies could be combined with the unique and often disturbing powers of Creepypasta entities like Jeff the Killer or Slenderman. It would be a chaos of different horror elements colliding.
A cool plot might be that the BNHA villains discover the Dream SMP and see it as a new place to expand their evil plans. They kidnap some of the SMP members thinking they can use them for something. The SMP members then team up with the BNHA heroes to fight back. Techno could use his combat skills and the BNHA heroes would be amazed at his fighting style without having a Quirk. And the SMP members could learn about the importance of working as a team like the BNHA heroes do.
You could write a story where the Afton family members are reborn in a different time period, but they still carry the memories of their past lives. They have to deal with the knowledge of what they did in their previous existence while trying to fit into this new world. This could lead to internal struggles, as well as external conflicts with those who might recognize them from their past.
The interaction between the Afton family's children, such as Elizabeth Afton, and the female Creepypasta characters like Jane the Killer could be really engaging. Elizabeth has her own dark backstory within the Afton family lore, and Jane is a strong - willed and vengeful Creepypasta character. They could either become enemies or find some sort of strange kinship in their shared experiences of being part of a dark and often male - dominated world of horror.
Maybe there's a villain in the Pokemon world who is using some kind of Pokemon - related power to cause chaos, similar to the villains in BNHA. The heroes from BNHA have to team up with local Pokemon trainers to stop this threat. They discover new Pokemon abilities that they can incorporate into their own fighting styles. For example, Todoroki could learn from ice - type Pokemon how to better control his ice powers.
One possible plot could be that the Big Three - Mirio, Nejire, and Tamaki - are transported to an alternate universe where they have to team up with their counterparts from different versions of BNHA. They face new villains and challenges that require them to combine their unique quirks in unexpected ways. For example, they might encounter a villain who can manipulate time, and they have to figure out how to use Mirio's intangibility, Nejire's wave motion, and Tamaki's transformation quirks to stop the villain before he destroys the fabric of the universes.
Well, one possible plot could be that Inuyasha somehow gets transported to the Family Guy universe. He might be really confused by all the modern and wacky things there, like Peter's antics. Maybe he would team up with Stewie, who's always into some sort of strange plan, and they could go on an adventure together. It could also involve Inuyasha's sword skills being put to use against some of the villains in the Family Guy world.
The Afton bedtime story might be about a group of Afton children who discovered a hidden garden in their backyard one day. At night, when it was time for bed, they couldn't stop thinking about the garden. In their dreams, they all went back to the garden. But this time, it was filled with glowing plants and friendly fairies. The fairies taught them about the magic of nature and how every living thing was connected. They showed the children how to make wishes on the dandelion seeds that floated in the air. When the children woke up, they were excited to go back to the real garden and explore more. They started taking better care of the plants in the garden, knowing that there was a special magic there. This story could teach Afton children to respect and love nature.
Well, it could be about Nico being nervous to meet Will's family at first. Maybe he's worried they won't accept him because of his dark past or his powers. But then, as he gets to know them, he realizes they're really warm and welcoming.
