Strangely almost all of my fav character are from Akatsuki lol

1:Sasori-Hes so freaking cool with all the puppets and poison tricks but sadly i think he die too soon in early arc

2:Deidara-I love his personality and bomb made out of cray

3:Kakuzu-He is creepy and cool at the same time with the tentacle and several hearts within body+Near immortality ability-ish

4:Hidan-Immortal villain with interesting ability sadly author lazy to put more character in final shinobi war

5:Konan-Her paper ability is so cool remind me of Kalluto from HxH,her scene vs masked obito was cool with the non-stop bombing waterfall abyss.

Other fav would be Zbz and Haku from Naruto the bridge arc was my fav arc in entire naruto+shippuden arc.
