In a fight, Korosensei could dodge attacks and then the Touhou characters could strike back with their magic at the right moment.

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 Rasengan could potentially be enhanced with the power of Okami's Celestial Brush.

For the Okami characters, Issun could use his small size and agility in combination with Naruto's shadow clone jutsu.

Amaterasu from Okami could combine her fire - like powers with Sasuke's fire jutsu, creating an even more intense and powerful flame attack.
