If we consider how the characters' abilities would combine in a Blue Exorcist and D Gray - Man crossover fanfiction, it's quite fascinating. Take Lavi from D Gray - Man, his Bookman skills of gathering information could be paired with the knowledge of the demon world that the Blue Exorcist characters possess. This could lead to a more in - depth understanding of the new threats they face. In terms of combat abilities, Bon from Blue Exorcist has his physical strength and martial arts skills. If he were to work with the more magically inclined characters from D Gray - Man like Miranda, they could create a balance between brute force and magical support. The combination of abilities would not only make for exciting battles but also open up new storylines as the characters discover new ways to use their combined powers to face the challenges that come their way.
Rin Okumura's blue flames could be used in combination with Allen Walker's anti - Akuma weapon. For example, Rin could use his flames to weaken an Akuma while Allen strikes with his weapon for maximum damage. Shiemi Moriyama's ability to communicate with plants could be useful in a D Gray - Man setting. She could use plants to detect hidden Akuma or create barriers. The exorcists in D Gray - Man could learn from the Blue Exorcist characters about different ways to combat evil spirits.
The characters' abilities could combine in really cool ways. Kanda from D Gray - Man has his sword skills, and if combined with Yukio Okumura's precise shooting and strategic mind, they could form a powerful combat duo. Allen's ability to sense Akuma could be enhanced by the spiritual senses of the Blue Exorcist characters. Maybe they could develop a new form of detection that combines both their methods. Also, the D Gray - Man characters' use of Innocence could be combined with the Blue Exorcist's use of sacred objects. For instance, the power of an Innocence - like object could be channeled through a sacred sword from Blue Exorcist for a super - powerful attack.
Well, Naruto's Rasengan could potentially be combined with Rin's blue flames. Imagine Naruto creating a Rasengan infused with the power of Rin's blue flames. It would be an extremely powerful and destructive attack. The Rasengan's spinning chakra could be enhanced by the purifying and burning properties of the blue flames, making it effective against both physical and spiritual enemies.
The Akumas in D Gray - Man are created by the Millennium Earl. If Akumas were to enter the Black Butler world, they would be a major threat. Their ability to transform and their inhuman strength would be a challenge for the Black Butler characters. On the other hand, Sebastian's demonic powers and his ability to make contracts could potentially be used to manipulate or destroy the Akumas. The D Gray - Man exorcists are trained to fight Akumas specifically, so their skills would be very useful in this new setting. But the Black Butler characters' knowledge of the local environment and their own unique skills, like Mey - Rin's sharpshooting and Bardroy's combat experience, could also contribute to the fight against the Akumas in ways the D Gray - Man exorcists might not expect.
One idea could be that the characters from Blue Exorcist are transported to the world of D Gray - Man. For example, Rin Okumura could meet Allen Walker. They might team up to fight a common enemy that is a mix of the demons from Blue Exorcist and the Akuma from D Gray - Man. Another plot could involve the exorcism techniques from both worlds being combined to defeat a super - powerful evil force.
Let's consider the Reds and Blues' weaponry. Their guns and high - tech gadgets could be combined with RWBY's unique weapons. For instance, a character like Tucker with his sword could potentially upgrade it with some Red vs Blue tech. On the other hand, RWBY characters' Semblances could be used to enhance the performance of Red vs Blue weapons. For example, Weiss's glyphs could be used to improve the accuracy or power of a Red vs Blue sniper rifle. And the teamwork aspect, like how the Reds and Blues communicate during combat, could be adopted by the RWBY teams to improve their own coordination.
The relationship between Naruto and Lavi would be quite fun. Lavi is a bit of a joker and Naruto's positive attitude would match well with him. They could team up and get into all sorts of adventures. Hinata might be a bit shy around some of the D Gray - Man characters at first, but she would gradually open up. The relationship between the Akatsuki and the Akuma would be very different. The Akatsuki are more about power and their own goals, while the Akuma are mindless servants of the Millennium Earl. However, some members of the Akatsuki might see the potential in using Akuma for their own ends, which would create a very dangerous situation for both worlds.
Well, Naruto's shadow clone technique could be really useful when combined with Spider - Man. Spider - Man could send out the clones to scout an area or distract enemies while he makes his real move. Also, Spider - Man's ability to stick to walls could be combined with Naruto's tree - climbing technique. They could scale buildings in new and amazing ways. And Naruto's Rasengan, if combined with Spider - Man's strength, could become an even more powerful attack.
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.
