Imagine a story where the Deathly Hallows are in the Teen Wolf world. The Teen Wolf characters don't understand what they are at first. But then they team up with some HP characters who have come to retrieve them. They have to battle a powerful dark force that wants to use the Hallows for evil in the Teen Wolf realm. This would combine the magical elements of HP with the action - packed werewolf lore of Teen Wolf.
First, you need to understand the two universes well. Know the rules of magic in Harry Potter and the werewolf lore in Teen Wolf. Then, create a unique plot that combines elements from both. For example, a spell that affects werewolves in a new way. Next, develop your characters. Let them interact in interesting ways. If Harry Potter meets Scott, how would they react to each other's powers? Also, keep the pacing right. Don't rush through the story but also don't drag it out too long.
One popular idea is a crossover with 'The Vampire Diaries'. The werewolves from 'Teen Wolf' could interact with the vampires and witches in that universe. It could lead to some really interesting power dynamics and relationships.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Use the search function and type in 'Teen Wolf crossover' and then browse through the results. Check the ratings and reviews of the stories to see which ones are highly recommended.
There could be a fanfiction where the Teen Wolf gang travels to a city where the Criminal Minds team is based. They notice some odd killings that seem to be related to a supernatural force. The BAU starts to investigate, not realizing the true nature of what they're dealing with at first. As the two groups interact, there are misunderstandings, like when the BAU tries to profile Scott as a potential suspect because of his enhanced abilities. But eventually, they join forces. Scott shares his knowledge of the supernatural world with the BAU, and the BAU uses their profiling skills to track down the real culprit, which is a powerful supernatural being that has been using human proxies to carry out its killings.
There's a fanfic called 'Teen Wolf in the MCU'. In this, the characters from Teen Wolf somehow end up in the Marvel Cinematic Universe. It's fascinating to see how Scott McCall and his pack deal with superheroes and super - villains. Also, 'Teen Wolf and Buffy the Vampire Slayer Crossover' is quite popular. It has Buffy coming to Beacon Hills to help deal with a new type of supernatural threat that the Teen Wolf gang can't handle on their own.
A must - read 'Teen Wolf Wolf OC Fanfiction' is 'The Wolf OC's Alliance'. This story focuses on the OC forming an unexpected alliance. It's a great read because it shows how the OC can change the power dynamics in the Teen Wolf world. The relationships developed in this fanfiction are complex and engaging.
Maybe a fusion where the Teen Wolf characters are transported to the Star Wars universe. They could get involved in the galactic conflict, using their Teen Wolf abilities in unique ways. For instance, their enhanced senses could help them detect Sith plots or find hidden Jedi artifacts.
One idea could be that the characters from Teen Wolf end up in the Fate universe and have to deal with the complex magic system there. For example, Scott could try to use his werewolf abilities to control the powerful magical forces in Fate. Another could be a love story where a character from Teen Wolf falls in love with a Fate character, like Stiles falling for a Fate mage. Maybe the Teen Wolf pack has to fight against a common enemy in the Fate world, something that combines the bestial nature of the werewolves with the magical threats of Fate.
Sure, it's normal. Just think about it. Fanfiction often delves deeper into the emotions, relationships, and backstories of the characters. For Teen Wolf, seeing these different takes on their own story could be really interesting. It's no different from an actor reading reviews or interpretations of their work. It's a way to be more involved in the cultural phenomenon that has grown around the show.
Survival is another big theme. In both Spartacus' world where they have to fight for their freedom against the Romans and in the Teen Wolf world where they are constantly facing supernatural threats, survival is crucial. In the crossover fanfiction, the characters often have to combine their skills to survive in new and unexpected situations.
