The Joker from the Batman universe could be an interesting crossover character. His chaotic and unpredictable nature would contrast well with Alice's own struggle with madness. He could be the one causing more chaos in Wonderland or wherever the crossover takes place, and Alice would have to find a way to stop him while also dealing with her own mental state.
Sailor Moon could be a great crossover character. Her positive and heroic nature would be a contrast to Alice's darker world. They could team up in a crossover where a new evil threatens both their worlds. Sailor Moon's powers of love and justice and Alice's determination from 'Alice Madness Returns' could make for a powerful duo against the common foe.
First, you need to study both universes thoroughly. Know the characters, their abilities, and the rules of their worlds. For Naruto, understand the chakra system, the different jutsus, and the various clans. For Alice: Madness Returns, be familiar with the nightmarish landscapes, the significance of the different items Alice uses, and her mental state. Then, find a common ground for the crossover, like a shared enemy or a similar theme such as fighting inner demons.
A crossover with a steampunk world would be cool. Picture Alice from 'Alice Madness Returns' arriving in a steampunk city where machinery and magic coexist. She could encounter characters like a steampunk Mad Hatter who is an inventor gone mad. The contrast between the dark, dreamy world of 'Alice Madness Returns' and the mechanical, yet fantastical, steampunk world would create interesting storylines and character interactions.
You can start by looking on fanfiction websites like Archive of Our Own. There are often many creative works related to 'Alice Madness Returns' there. Just use the search function and type in 'Alice Madness Returns Carpenter' to narrow down the results.
Sora from Kingdom Hearts could be an interesting choice. Sora's positive and heroic nature would contrast with Ragna's more brooding personality. They could team up to fight against the Heartless that somehow invaded Ragna's world or vice versa.
Definitely Geralt from The Witcher. His knowledge of monsters and magic could complement the Doom Slayer's brute force. They could work together to hunt down some powerful demons that are causing chaos in both their worlds.
Another theme is the exploration of the characters' mental states. In both the original works, the characters have their own traumas and challenges. In fanfics, this is often delved into deeper. For instance, how Naruto's experiences with loneliness might compare to Alice's feelings of being lost in her own madness. It's a way to create deeper connections between the characters from different universes.
Character development is key. The fanfic should develop Carpenter's character further, maybe give him a backstory that wasn't fully explored in the game. It could also show his relationship with Alice in a more complex and interesting way. If it can make the readers feel more connected to the character, it's a great fanfic.
Well, 'Alice and Naruto's Adventure' is a fanfic that focuses on a team - up between Alice and Naruto. They embark on a journey to solve the mysteries that connect their two worlds. It has a lot of character development for both of them as they learn from each other's strengths and weaknesses.
Aang could be a great crossover character. Since he is from the previous Avatar cycle, his different approach to bending and his more laid - back personality compared to Korra could create interesting interactions. He could offer her wisdom from his own experiences as an Avatar.
Sanford and Deimos are also great choices. Their friendship and teamwork could be a contrast or complement to the relationships in the other world of the crossover. They could bring in their own unique skills, like Sanford's strength and Deimos' marksmanship.
