I was originally gonna say Gaara's father but then I found out the truth...So my least favorite is...
DANZO SHIMURA!!!! D:<
Very VERY evil man! He didn't let the anbu help in the battle with pain and he ruined the Uchiha's lives! He did NOT deserve to be Hokage! He deserves to be behind bars! I HATE HIM!!!!!
That is all :3
