Who would be the most interesting character combination in an 'FNAF Undertale crossover fanfiction'?

I think Freddy Fazbear and Toriel would make an interesting pairing. Freddy is this big, imposing animatronic, while Toriel is a motherly figure. Their interactions could be really cool, like Toriel trying to understand what Freddy is and Freddy being a bit confused by Toriel's kindness.

Naruto would be really interesting. His never - give - up attitude would make him stand out in the spooky FNAF world. He'd probably be the one to charge headfirst into danger, whether it's facing the creepy animatronics or trying to solve the mysteries of the place. He could also try to befriend the animatronics if he thought they were being controlled against their will, just like he did with some of his enemies in the Naruto world.

Carly and Jade could be really cool together. Carly is sweet and friendly, while Jade is edgy and a bit of a troublemaker. Their interactions would be full of contrast. Carly might try to soften Jade a bit, and Jade could introduce Carly to a more rebellious side of life in Hollywood Arts.

I think the combination of the Doom Slayer and Anya Oliwa from Wolfenstein could be really interesting. Anya is a strong and intelligent character. She could provide the Doom Slayer with valuable information about the Wolfenstein world, like the layout of Nazi bases and their technology. Meanwhile, the Doom Slayer could protect her with his incredible combat prowess. This dynamic could lead to a story where they work together to uncover a deeper conspiracy that links the demons and the Nazis.

Definitely Spider - Man and Mr. Incredible. Mr. Incredible has brute strength and experience in dealing with super - villains. Spider - Man, on the other hand, has his acrobatic skills and spider - sense. Their combination would be interesting as they could learn from each other's combat styles. Mr. Incredible could teach Spider - Man how to use his strength more effectively in close - quarters combat, while Spider - Man could show Mr. Incredible how to be more agile and use the environment to his advantage with his web - slinging.

I think Leonardo and Papyrus would make an interesting pairing. Leonardo's leadership and discipline could contrast with Papyrus' more naive and enthusiastic nature. They could learn from each other, like Leonardo teaching Papyrus some ninja moves, and Papyrus showing Leonardo how to have more fun. Another great pairing could be Donatello and Alphys. They are both the 'tech - smart' characters in their respective universes. They could collaborate on some crazy inventions that combine Undertale technology and Turtle - made gadgets.

I think Monika would be really interesting. In DDLC, she has that self - awareness and a certain level of power over her world. If she were in Undertale, her attempts to understand the very different rules of that world would be fascinating. She might try to use her powers to change things, but in Undertale, the concept of determination and the power of the player is very different. So seeing her interact with characters like Flowey, who also has some unique powers and knowledge, could lead to some really intense and thought - provoking scenes.

Sans is another great choice. His laid - back but extremely powerful nature in Undertale would create a lot of interesting dynamics in a Deltarune world. He could befriend or baffle the Deltarune characters. For example, his time - related abilities would be very different from anything in Deltarune, and it would be fascinating to see how he uses them in a crossover situation, like against the Darkners.

Ruby and Frisk would be a really interesting pairing. Ruby is full of energy and determination, and Frisk has that unwavering kindness. They could learn a lot from each other, especially in terms of how they approach difficult situations and make decisions.

Aphmau from MyStreet and Freddy Fazbear would be an interesting combination. Aphmau is a strong - willed leader in her world, and seeing her face off against Freddy, the iconic animatronic from FNAF, would be exciting. Another interesting pair could be Aaron from MyStreet and Foxy. Aaron is often protective, and Foxy has that unpredictable nature.
