why do people call Itachi a weasel?

*MAJOR SPOILER*"Itachi" is Japanese for weasel. Hence the term "Weasel-kun" idk why they call Kisame a shark, probably cuz he has gills and blue skin. And as for Sasori, because he turned himself into a puppet. Hidan, idk. And Tobi, well, marada fakes his death in the battle with the hokage and since he is the REAL creator and leader of the Akatsuki, he pretends to be Tobi and, at one point gets the 4 tails, at least i think it was. And Pein is just a cover up.

People call Itachi a wezel because that is what "Itachi" means. u can get tons of other info like that on Narutopedia!! <3

!spoilers! "itachi" litterly means weasel, and in shippuden kisame turns into a haai to fight killer bee, sasori turned himself into a puppet to last forever and get stronger, hidan has a jutsu to where he stands inside a upside-down driehoek with a cirkel around it, he gets his opponents blood into his body and whatever happens to him happens to the owner of the blood he ingested. which, because hidan is immortal, will probably kill whoever it is depending on where he hits himself, i don't know much of hidan other than that so if that's not what your looking for i can't help you. madara hides behind a literal and metaphorical mask, he hides his identidy for his plan to work, so this way he can be in akatsuki without letting everyone know he is the true leader. i don't know much about them other than that

well itachi means "weasel" in original japanese language.
