Nah its not possible for itachi to solo kabuto when he was busy being solo'd by kabuto, deal with it kabuto ****ed itachi up and tore him a new one and made it look easy, and kabuto probably could have made the fight look easier if he wasn't so busy talking, sad but true....just sayin..
izanami is irrelevant though. since kabuto should have been able to win easily in the first few minutes with hakugeki but sasukes presence and itachi's edo tensei enabled itachi to survive that.
also if kabuto had edo army he would have stomped.
I'm not trolling this time. Itachi defeated Kabuto without Sasuke. In fact, Sasuke was a burden, considering Itachi saved him from being digested
Ugh....ok I already stated this in my first comment that you need to complete a loop in order for Izanami to fully activate....Itachi even said this
He first used Izanami in the first stab......it has no effect until the movements are replicated in order to deceive the senses, and that happened once he got stabbed the second time....
You must be registered for see images
you even see him lose his eye after the second stab, and Kabuto was still missing his horn throughout the whole replication process only until the loop was finished

Itachi died multiple times before the loop was finished and you can clearly see Kabuto still missing his horn
