harry potter and undertale crossover fanfiction

One idea could be that Harry Potter accidentally finds a portal to the Undertale universe while exploring the Forbidden Forest. He has to learn the rules of this new world, like dealing with the concept of LOVE and EXP. Maybe he teams up with Sans to fight off Voldemort who has also found his way into the Undertale world and is causing chaos by using dark magic on the monsters.

Another interesting pairing would be Ron and Papyrus. Ron is known for his loyalty and his love for food, and Papyrus is this enthusiastic skeleton who loves cooking and making friends. They could bond over food, with Ron introducing Papyrus to some wizarding world delicacies like Butterbeer and Pumpkin Pasties, and Papyrus showing Ron his 'Spaghetti Surprise'. Their friendship could also be a source of comic relief in a more serious crossover story.

One common theme is the exploration of different worlds. Since Harry Potter has Hogwarts and the wizarding world, and Undertale has the Underground, fanfictions often focus on how characters move between and adapt to these different settings. For example, a character from Harry Potter might be confused by the rules in the Underground at first.

Maybe in the 'Harry Potter in Undertale fanfiction', Harry discovers that Voldemort has also found his way into the Undertale world and is trying to gain power there. Harry has to learn the rules of this new world quickly. He befriends Sans and Papyrus. Sans, with his knowledge of the resets in Undertale, helps Harry understand how to manipulate time in a way that could give him an edge against Voldemort. Papyrus, on the other hand, is enthusiastic about Harry's magic and they train together to fight off Voldemort's minions in the Undertale world.

There's 'Potter in the Underground'. This fanfiction delves deep into how Harry Potter would navigate the Underground world of Undertale. It has a great plot where Harry uses his magic in new and creative ways within the Undertale universe, and the author does a wonderful job of merging the two storylines.

Sure, it's quite possible. Fanfiction writers love to blend different fictional worlds. In a 'The Mummy (2017)' and 'Harry Potter' crossover, we could see the mummy's powers being pitted against the spells of Hogwarts students. Maybe the mummy is brought back to life in the wizarding world and causes chaos. There are endless possibilities for interesting storylines in such a crossover fanfiction.

One idea could be that Tinkerbell finds her way into the wizarding world of Harry Potter. Maybe she gets accidentally transported there by some magical mishap. She could use her fairy magic in Hogwarts, like helping to repair broken objects in a more sparkly and unique way compared to the Reparo charm.

A popular one is 'Fem Harry and the World of Middle - earth'. This fanfic is really interesting because it crosses over the Harry Potter universe with Tolkien's Middle - earth. Here, Fem Harry has to adapt to the very different cultures and magic systems in Middle - earth, and there are some great character interactions that add depth to the story.

Yes, it could be. It's a very interesting and unique concept. Combining Harry Potter with the Riddler from Batman is quite unexpected. It might involve putting Harry Potter in a situation where he has to solve riddles like the Riddler creates, or perhaps there are elements of mystery from the Riddler's world incorporated into the magical world of Harry Potter.

One idea could be that the Avengers are somehow transported to the wizarding world. They might be initially confused by the magic but then start to work with the Hogwarts students and teachers to fight a common enemy, like a dark wizard who has also harnessed some sort of Muggle - like technology to become even more powerful. For example, Voldemort could team up with Hydra remnants to create a super - weapon that threatens both the magical and non - magical worlds.
