jiraiya summoned frog intestine or whatever and itachi used amaterasu to escape from it. jiraiya sealed the black flames afterwards.when did jiraiya fight itachi and get hit with amaterasu?
QFT!Well , if u look at susano like Itachi was able to make , that pwns both Kamui and amaterasu.
Jiraiya was not targeted. Amaterasu was just in front of him and took his time to seal it. Itachi's Susano'o is the strongest. Then, it could be Gedo Mazo ( I think it's Rinnegan-based ).are you comparing just kamui and amaterasu? then i don't know kamui is pretty dope.. if you get hit, that's it unless, like madara you have some special space time ninjutsu. with amaterasu, if you get hit you can seal it no problem like jiraiya did, but it's still going to leave some damage. i think it all depends on the user and how they use it. if you asking what the strongest doujutsu is, it's basically like this:
rinnegan>ems>ms>sharingan stage2>byakugan>sharingan
so6p rapestomps all.
