What are some interesting ideas for a Chucky crossover fanfiction?

One idea could be that the reader is a detective trying to solve the mystery of Chucky's murders and ends up in a strange psychological battle with him. Another could be that the reader is a dollmaker who discovers Chucky's true nature and has to decide whether to help him or stop him. Or perhaps the reader is a psychic who can communicate with Chucky on a spiritual level and tries to exorcise his evil.

A really interesting plot could be that Chucky and Tiffany discover a way to reverse their doll - turned - human situation. But as they try to do so, they face various obstacles, like a powerful enemy who wants to keep them as humans for their own malicious purposes. They have to fight this enemy while also dealing with their own internal conflicts about whether they really want to go back to being dolls.

One idea could be that Chucky and Buddi form an unlikely alliance to take on a common enemy in the toy world. Maybe a new, more evil toy is threatening their existence.

A plot idea could be that Chucky gets cursed in a way that he is forced to protect Andy. So, he has to follow Andy around and keep him safe from other threats in the horror - filled world they inhabit. This would lead to a lot of comical and also tense situations as Chucky is not used to being a protector. And they could gradually develop an understanding of each other's perspectives during this time.

One idea could be that Andy, now grown up, has to face Chucky again when Chucky resurfaces in a new, more devious form. Maybe Chucky is using modern technology to his advantage, like hacking into security systems to get to Andy.

One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.

One plot idea could be Chucky and Tiffany going on a wild adventure to find a powerful voodoo artifact that could make them even more invincible. They face various obstacles and other evil dolls along the way.

Another interesting concept could be a crossover with a historical setting. Imagine a world where historical figures' actions are judged by karma in a modern - day - like system. So, for instance, a cruel king from history might be reincarnated into a peasant in this fanfiction and has to endure hardships to pay off his bad karma.

A Goku crossover with the Pokémon world could be really fun. Goku could try to catch Pokémon using his speed and strength. He might also team up with Ash to battle powerful Pokémon trainers. Or how about a crossover with the Digimon world? Goku could enter the Digital World and help the Digimon in their battles against evil Digimon using his energy attacks.

One idea could be a crossover with the Halo universe. Imagine the Doom Slayer facing off against the Covenant. Another could be a crossover with the Warhammer 40K universe, where the Doom Slayer battles Chaos forces in a hellish landscape that combines both universes. Or a crossover with the Mass Effect universe, where the Doom Slayer's brutal combat style clashes with the more strategic and technological approach of the Mass Effect races.
