Definitely Sakura and Sid. Sakura is a strong - willed and intelligent character. Sid is a bit of a goofball. Sakura could be constantly exasperated by Sid's antics, but at the same time, Sid could bring out a more fun - loving side of Sakura. And Sakura could use her medical ninjutsu to help Sid if he gets injured during their adventures in the Ice Age world.
I think Naruto and Manny would be an interesting combination. Manny is this big, strong mammoth, and Naruto is a skilled ninja. Their personalities are so different. Naruto is full of energy and always eager to prove himself, while Manny is more of a calm and protective leader. It would be fun to see how they interact and how Naruto's ninja skills might come in handy in the Ice Age world with Manny's brute strength.
Manny from the Ice Age could be very interesting. In a crossover, he would be the big, strong and somewhat skeptical character towards the Naruto bunch. He has his own code of honor in protecting his herd, and seeing how he interacts with the ninja, especially with their strange powers like Naruto's Rasengan, would be really cool. He might start off not trusting them but eventually come to respect them.
Naruto and Eren would be an interesting combination. Naruto is full of optimism and determination, while Eren has a deep - seated hatred for the Titans. Their different personalities could create some great character dynamics. Naruto could inspire Eren to be more positive in his fight against the Titans, and Eren could show Naruto the harsh reality of the world he lives in.
Naruto and Rick would be a really interesting combination. Naruto's optimism and never - give - up attitude could inspire Rick, who has seen so much horror. And Rick's leadership skills and survival instincts could teach Naruto a thing or two about dealing with a post - apocalyptic world. They could work together to lead their respective groups and fight off the walkers and any other threats.
Naruto and Rias would be really interesting. Naruto's straightforward and determined personality combined with Rias' leadership and strategic mind could lead to some great interactions. They could learn from each other's fighting styles and ways of dealing with problems in their respective worlds.
I think Naruto and Alice would make a great combination. Alice can see the future, and Naruto has his ninja skills and immortality. They could team up to prevent some disasters in both worlds. Alice could foresee the problems, and Naruto could use his powers to stop them. And Naruto's immortality would give them more time to plan and execute their strategies.
I think Ben's Heatblast and Thor would be an interesting combination. Heatblast can generate intense heat and fire, while Thor has his lightning powers. They could create some really powerful elemental attacks together.
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.
Frisk and Chica would also be a cool combination. Frisk is all about kindness and determination, and Chica is this animatronic with a bit of a goofy side. Frisk could try to understand Chica's motives and maybe even help her find a new purpose other than scaring people at night.
