Dis 2 men from what I hav seen from dem are d 2 strongest in Naruto(currently). Whe dey team up I bleve no other duo can match up with them. Itachi has Koto Amatsukami while Nagato has his 6 paths along with himself.
4 those who can perform Edo Tensei ie Orochimaru, Tobirama n Kabuto they can only summon those who are in d range of being summond(excludin Nagato) meanin d first 4 Hokages can't b summond n neither can Itachi cos of what we saw in d last manga. they are also limited in ther ET a was seen in d manga(except Tobirama). Oro=3, Tobirama=1 and Kabuto=30
