kakuzu has fire element so he can beat the FRS.
narutos taijutsu wont help much because elements will blast him to nothingness.
only way i see naruto winning is by mass shadow clone smapping and even then kakuzu can absorb all his hearts into his body and just blast naruto away from every angle, so i dont think naruto can win
You're certainly entitled to your opinion, however ludicrous it may be.
Fact of the matter is Kakuzu is a minor side character, and that's at best.
