Can someone explaine this.

[bashkim]

When Jiraya fought Pain he used in Sage Mode uses Ultra-Big Ball Rasengan.

When Naruto fought Kurama he used Sage Art: Ultra-Big Ball Rasengan .

Are their difference in size or power ?

You name two jutsu that are the same and ask what the difference is with them?

The only difference is the user.

 

[ᖇ α z m α η]

The technique is strong as the user and the amount of chakra they're utilizing in it.​
