Juubi vs 9 Bijuu

[Nèro]

The Juubi takes on all 9 Bijuu...

 

[Papasmurf]

Juubi wins unless it's Kaguya at the helm, then she's too idiotic to ever beat anyone powerful with any sort of skill.

 

[Captain Cadaver]

Even after separating the Juubi's power into the 9 Bijuu, Hagoromo still had to seal it inside the moon, meaning it's power must be at least slightly greater than that of the combined power of all 9 Bijuu.
