Naruto and Inuyasha themselves would be a very intriguing combination. Naruto's positive attitude and never - give - up spirit combined with Inuyasha's rough - around - the - edges but strong - willed personality would create a lot of interesting interactions. They could start off not liking each other but gradually become friends as they face challenges together.
Kakashi and Miroku would also make for a great combination. Kakashi is a very skilled and mysterious ninja, while Miroku is a monk with his own set of skills and a bit of a playboy personality. They could share their knowledge of different fighting styles and also have some humorous exchanges about their different cultures and ways of life.
Sakura and Kagome would be an interesting pair. Sakura, with her medical skills and combat abilities from the Naruto world, could team up with Kagome, who has her own spiritual powers and knowledge of the Inuyasha world. They could support the male characters in different ways, like Sakura healing wounds and Kagome using her spiritual powers to detect threats.
Sasuke and a fox demon with a similar past of loss. Sasuke has his own dark past with the Uchiha clan's massacre. A fox demon who has lost their family or pack could bond with Sasuke over their shared experiences. They might even develop a unique fighting style together, combining Sasuke's Sharingan - enhanced jutsu with the fox demon's special abilities.
One intriguing combination would be Hermione and Neytiri. Hermione's thirst for knowledge and Neytiri's connection to Pandora's nature could lead to some great interactions. Hermione could learn from Neytiri about the unique flora and fauna of Pandora, and Neytiri could be fascinated by Hermione's magic and her ability to study and understand complex things.
Sesshomaru could also be a very powerful character in this crossover. He has his own powerful sword, Bakusaiga, and his inhuman strength and speed. He is very experienced in combat against demons. Compared to Naruto's friends like Sakura, Sesshomaru would likely be much more powerful in terms of raw strength and combat ability. But Sakura has her own medical ninjutsu and superhuman strength when she releases her inner power, which could also be useful in different situations.
It's hard to say for sure. Naruto in his Sage Mode or with the power of the Nine - Tails is extremely powerful. He has a vast amount of chakra and can perform powerful jutsus. However, Inuyasha with his Tessaiga, especially when it's in its upgraded forms, is also a force to be reckoned with. He has superhuman strength and speed, and the Tessaiga can cut through almost anything. But if we consider all aspects, Naruto might have an edge as he can use a wider variety of techniques and has more experience in large - scale battles.
Naruto and Kirby would be really interesting. Kirby could copy Naruto's abilities, like his running speed or his ability to use chakra. And Naruto could be amazed at Kirby's cuteness and his unique way of fighting, like inhaling enemies. They could have a really fun dynamic together.
One of the most intriguing combinations is Harley Quinn and Alice Cullen. Harley's chaotic and unpredictable nature paired with Alice's calm and prescient abilities would create a really interesting dynamic. They could either be at odds or find a strange kind of friendship. Another good combination is Deadshot and Edward Cullen. Deadshot's sharpshooting skills and his more jaded view of the world contrasted with Edward's brooding and his vampiric powers would make for some great scenes.
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.
Well, for one, Harrison Wells from Flashpoint and Castiel would be really interesting. Wells is a brilliant scientist, and Castiel is an angel. Wells could be intrigued by Castiel's otherworldly nature and try to study him, while Castiel could use Wells' knowledge to better understand the science - based threats in the Flashpoint universe. Another cool combination would be Felicity Smoak from Flashpoint and Rowena from Supernatural. Felicity is a tech - genius, and Rowena is a powerful witch. They could either be rivals, with Felicity trying to use her tech to counter Rowena's magic, or they could team up and create some really powerful spells or gadgets. And then there's Oliver Queen from Flashpoint and Sam Winchester. Oliver is a skilled archer and fighter, and Sam is a hunter. They could share their combat techniques and knowledge, and together they could take on some really tough opponents in both the Flashpoint and Supernatural worlds.
Definitely Superman and Thor. They both have super strength and are associated with powerful, other - worldly elements. Thor has his hammer and lightning powers, while Superman has his super - strength, heat vision, etc. It would be interesting to see them compete in a friendly strength - based challenge or fight side by side against a really strong foe.
In my opinion, Aizen could be one of the most powerful characters in such a crossover. His intelligence and his ability to manipulate others are already very dangerous in the Bleach universe. If he were to enter the Inuyasha world, he could easily use his wits to turn the different factions against each other. He could also potentially find a way to use the demon energy for his own gain. His Zanpakuto's powers are also very versatile and could give him an edge against the characters in Inuyasha's world.
