Think about Sakura's superhuman strength. In a RWBY crossover, she could use that strength to help move heavy objects or in close - combat against the Grimm. Her medical ninjutsu could also be combined with RWBY's technology. Maybe she could develop new ways to heal using Dust - infused medical tools. For the RWBY characters, Yang's Semblance of absorbing damage and then releasing it as power could be combined with Naruto's ability to draw on the Nine - Tailed Fox's power. Yang could learn to better control the absorbed energy by using some of Naruto's chakra control techniques.
Well, Naruto's Rasengan could be combined with Ruby's Crescent Rose. For example, Ruby could use the spinning force of the Rasengan and incorporate it into her scythe attacks. It would add a new level of power and unpredictability. Sasuke's Chidori could be used in a similar way, perhaps with Weiss' Glyphs. She could create Glyphs that enhance and direct the power of the Chidori for more precise attacks. And Naruto's shadow clones could be used in RWBY battles. They could be used to distract Grimm while the RWBY characters set up more powerful attacks.
Well, Soldier 76 has his healing ability. In a crossover, this could be used to keep RWBY characters alive during tough battles. Let's say Weiss is in a fight and gets injured. Soldier 76 could heal her up quickly so she can continue using her Glyphs. His ultimate ability, the Tactical Visor, could be combined with Ruby's sniper skills. They could both target enemies from afar and take them out more efficiently. Also, his combat experience and training could be shared with the RWBY team, improving their overall combat strategy. And the RWBY characters' unique Semblances could also enhance Soldier 76's abilities. For instance, if he teams up with Pyrrha, her polarity semblance could be used to manipulate the path of his bullets.
Ruby's speed and scythe - wielding skills could be enhanced by the Keyblade's magic. For example, she could use the Keyblade's power to make her Crescent Rose even more powerful, like adding elemental attacks. Sora's ability to quickly adapt to new situations and his combat skills with the Keyblade could be combined with the Huntsmen training in RWBY. He could learn new fighting styles from the RWBY characters and they could learn from his experience with different enemies. Donald and Goofy's support abilities could be used to assist the RWBY teams in battles, like Donald's magic for healing or Goofy's defense - boosting skills.
Ruby's speed and scythe - wielding skills could be combined with Kaneki's kagune attacks. For example, Ruby could use her speed to quickly dodge an enemy's attack and then Kaneki could follow up with a powerful kagune strike. Weiss's glyphs could be used to enhance or control the movement of a ghoul's kagune. Blake's shadow clones could be used to confuse the ghouls while the Tokyo Ghoul characters attack from different angles.
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.
