Run whatever you want that make you laugh and enjoy the game, kakuzu probably the most boring ninja to ever see at-least six path had cool animation and a whole style and base off a character

Kakuzu just there to be there, but if you wanna get easy wins then sure why not but I can promise you he's kinda stale and boring ...you get to hear his *HRUMPGH* every time he standards and he steals people hearts :D
