^^^^lmao was thinking the same thing.
back on topic since i came late, strongest i know of is the 4th, 3rd, then jiraiya, then itachi, oro, tsunade.
@ itachi fanboys that are gonna try to flame: i dont think jiraiya is stronger then itachi, but i think he has techiniques that can defeat itachi, which is why itachi is hesitant to fight him.
