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.
Well, let's consider the different abilities. The RWBY characters have their unique Semblances which are often related to some aspect of their personality. Yang's Semblance of strength based on taking damage, for example. In a crossover with Red vs Blue, the Reds and Blues would have to figure out how to deal with that. The Red vs Blue characters, like Caboose's strange but sometimes effective combat style, would be a mystery to the RWBY characters at first. They would need to study each other's abilities. The RWBY characters' ability to use Dust in their weapons also adds another layer. The Red vs Blue characters might try to incorporate it into their own arsenal if they can figure out how it works. And the Reds and Blues' knowledge of advanced technology could potentially be used to enhance the RWBY characters' weapons or defenses if they are willing to cooperate.
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, 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.
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.
Dante's devil-trigger ability could combine well with Ruby's semblance. Ruby can move at high speeds, and when Dante enters devil - trigger, his enhanced speed and power could be added to Ruby's, creating a super - fast and powerful combo in battle. For instance, they could perform a combined attack where Ruby zips around enemies, and Dante follows up with his powerful sword strikes in devil - trigger mode.
Ruby might try to incorporate some of the unique concepts she finds into her own battles in Remnant. She's always looking for new ideas. Weiss would probably question the logic behind some of the concepts, especially if they don't match up with her understanding of how things should work. Yang would be more likely to use the concepts for entertainment value, like making jokes about them.
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.
Ruby and Church could form an alliance. Ruby is always eager to make new friends and fight for what's right. Church, despite his snarky attitude, has a good heart deep down. They could bond over their leadership roles in their respective teams and share their knowledge about combat and strategy.
