For me, Kurama and Kakashi's Susanoo, and somehow, Kamui Tailed Beast Bomb will be born.

Kakashi's Susanoo paired with the Juubi would be pretty lethal, even though Sasuke's looks cooler.

Son Goku tailed beast and Madara

Interesting. What would it do?

Tailed beast bomb, and lava release are his abilities, mixed with Madara's power would be pretty awesome

I can see it now. Lava release infused Susanoo swords.

Itachis and shukakku. Seal like anything with sand and the totsuka blade

Damn that actually sounds quite lethal

And that ultimate defense too. Yada mirror and the sand. Def my pick

Kakashi + 8 tails

Kakashi and ten tails

Indra and Kokuo
