I was jux thinking of how powerful kabuto is. And i was thinking that he's actually really powerful. One coffin(deidera) could delay kabuto enough time to capture yamato from a kage and 2 other jonins. so imagine him with all those other coffins. But thats not it. he has Itachi and Pain. O.O .... Now who can possibly take on all those coffins and win?? seriously!! Now aint you glad that the sword and shield that was equiped to itachi's susanno was a personal equip. how would you feel if kabuto had the power to freely swing around a legendary sword that seals anything away that it touches and block with an impenatrible shield that can withstand any jutsu. hmm...would'nt sound to good... i know ppl would say naruto could beat him. but how? i mean, do you really think naruto alone (with everything he has) has the power to stop former jinchuriki's,former kages, and elite jonins?? don't chu think that that's kinda out of naruto's capacity. i mean he could probably beat like 2 maybe 3, but thats pushing it kages. but that's all i could see from him. even the 3rd hokage extremely struggled with a weak edo tensa ( according to kabuto) that orochimaru summoned. 3rd hokage was old. GRANTED. but seriously. now kabuto says he's masterd it farther than the two before him. and he's proven it so far with who he can summon. So what i'm trying to say is. Who can beat Kabuto on a One on One fight? Remember Kabuto is insanely intelligent. Stupid powerful. and Still has an unknown coffin which made tobi accept his alliagence proposal. Remember Edo Tensei is a JUTSU so that still makes kabuto a single person.
