@bold: i beg to differ U_U
4th Kazekage > Shukaku
3rd Raikage >=< Hachibi
Minato >=< Kurama
Madara or Hashirama > Kurama (although they're behond kage level but whatever).
Minato is not stronger or equal to Kurama. He was capable of sealing it with what could be considered the strongest seal we've seen thus far. Which also kills him. The best he can do is teleport the bijuu bombs away. Impressive, but he is not stronger.
The 4th Kazekage was able to stop a rampaging Gaara. Naruto and Gamabunta did the same thing. It's obviously not as powerful as a released Shukaku would be.
The third Raikage is a special case, he stalemated with the Hachibi. Got me there I guess.
Hashirama and Madara. . Sorta. Hashirama more so, he can surpress their chakra. Madara can technically control them.
And I meant in overall power, anyways. Perhaps the last three mentioned can compete with the Bijuu.
