Well, in this crossover, Sakura's medical ninjutsu could be a great asset. She could heal any injuries that the Until Dawn characters might get during their encounters with the supernatural. In return, the Until Dawn characters could show her how to use the limited resources in the spooky environment for medical purposes. Naruto's ability to sense chakra could be used to detect the hidden threats in the Until Dawn world, which are not visible to the normal eye. And the Until Dawn characters could teach Naruto and his friends how to set up better traps using the materials available in their world.
Naruto's ability to create shadow clones could be used in the Until Dawn world for various things. For example, he could send clones to scout different areas of the spooky lodge. The Until Dawn characters' survival skills could combine with Naruto's combat skills. They could teach him how to make better use of the environment for protection, while he teaches them some basic ninjutsu moves.
The characters from Until Dawn might not have the flashy powers like in Naruto, but they have strong survival instincts. If combined with Naruto's chakra control, they could achieve some amazing feats. For instance, a character like Sam could use chakra to enhance her stealth even more. And Naruto could learn from their ability to stay calm under pressure. His Rasengan could be modified with the knowledge of the Until Dawn world's unique elements, like using the cold weather to make it more powerful.
If Naruto was in the Splatoon world, his Shadow Clone Jutsu could be used in interesting ways. He could send clones to cover more ground during an ink battle, confusing the enemy. And for the Inkling's part, their ability to swim in ink could help Naruto move around in ink - filled areas more easily. They could also use their ink guns to provide cover for Naruto while he attacks up close.
Well, if Izaya from Durarara and Shikamaru from Naruto were to team up, Izaya's intelligence in manipulating people and Shikamaru's strategic thinking could create some really devious plans. Shikamaru could use his shadow - binding jutsu to physically restrain opponents while Izaya uses his words to mislead and confuse their enemies. Another example is if Celty's shadow powers were combined with Naruto's chakra - enhanced strength. Naruto could use Celty's shadows to extend his reach in battle, like creating shadow - arms that are empowered by his chakra.
Naruto's ability to use chakra and his shadow clone jutsu could be combined with the Ninjago ninjas' elemental powers. For example, Naruto could create shadow clones to help Kai with his fire - based attacks in a battle.
The sharingan ability from Naruto's world could be used in an interesting way with the Voltron technology. For example, a character with the sharingan could quickly analyze the weak points in the Galra's defenses or the mechanisms of the Voltron lions themselves, allowing for more efficient repairs or strategic attacks. And Voltron's ability to form into a giant robot could be used as a cover or a platform for Naruto characters to perform their long - range jutsus from a safe vantage point.
Naruto's ability to use chakra could be combined with Batman's gadgets. For example, Naruto could use his chakra to power up some of Batman's energy - based weapons. Batman's detective skills could help Naruto in his ninja missions in the Naruto world. He could analyze the enemy's patterns and strategies better. Also, Naruto's shadow clone technique could be used for reconnaissance in Gotham, while Batman's stealth could be applied in the Hidden Villages for spying on potential threats.
Naruto's Rasengan could be combined with Kirby's inhaling ability. Kirby could inhale an object and then spit it out with the force of a Rasengan. Or Naruto could use his shadow clones and have each clone team up with a Kirby ability. For example, one clone could work with Kirby's sword ability to fight enemies.
Naruto's Rasengan could be combined with Aladdin's acrobatic skills. Imagine Aladdin using his speed and agility to get close to an enemy while Naruto forms a Rasengan, and then Aladdin quickly delivers the Rasengan - powered attack. It would be a very effective and unexpected combination.
Naruto's Rasengan could potentially be enhanced with the power of Okami's Celestial Brush. Imagine a Rasengan that can not only cause physical damage but also purify the area it touches, similar to how Amaterasu in Okami purifies the corrupted areas. For the Okami characters, Issun could use his small size and agility in combination with Naruto's shadow clone jutsu. He could ride on the clones and direct them to different strategic positions during a battle. Amaterasu from Okami could combine her fire - like powers with Sasuke's fire jutsu, creating an even more intense and powerful flame attack.
If Pikachu were in the Naruto universe, Naruto could use his Rasengan and Pikachu could add an electric charge to it, creating a super - powerful attack. Sasuke could use his Sharingan to predict the moves of Pokémon in battle and then counter them with his ninjutsu. Sakura, with her superhuman strength, could potentially team up with a Machamp to do some really powerful physical combos.
In terms of speed, characters like Sasuke from Naruto are extremely fast. If combined with the agility of a Descendants character like Evie, they could perform some amazing acrobatic feats. Evie could use her knowledge of potions and such to enhance Sasuke's Sharingan abilities further. Maybe she could create a potion that makes the Sharingan more perceptive or gives it the ability to see through certain types of magic.
