>is the only ally of Sasuke that joins him for his own goals and motives, is less of a plot device and more of an actual character compared to Karin and Jugo
>is turned into a completely bland character after 5ks who blindly follows Sasuke and Orochimaru without having any personal motivations
Is there anyway Kishi could've salvaged this character? Maybe make him join the allied nation and have him fight the former swordsmen of the Mist for their swords or something?
