I don't know much about the old character that lived before the series, so I'll be skipping them and judge on the characters that were alive and showed their powers. 1. Pain. 2. Konon(on basis of Konan vs Obito, even though she needs to seriously heavily prepare for it, it's still should count as one of her techniques) 3. Oonoki 4. Deidera(his explosions would be almost unbeatable, only weakness to it were lightning users, but they need to know about the weakness first to counter against it) 5. A, he basically bliztes everyone and can tank almost anything. 6. Sasori. 7. Killer Bee 8. Gaara. 9. Kisame. 10. Kazuku.

(I would have added Orochimaru and Kabuto, but I wonder if they are consider Leaf or Sound Shinobi? And maybe Shin from the Anime, I guess)
