It's 6 v 1 asuma is useless when kakashi fougth kakuzu he could barely keep up and had help from a lot of shinobi he would get destroyed I don't know how strong kakashi is in the war because I don't read the manga but I heard he is good
no, its 11 vs 1
full knowledge: kakuzu + 4 + kisame + 4 water clones + samehada = 11
