Obito Uchiha was a ninja of Konoha at 13. Being killed in action and then kidnapped by Madara, the man ended up growing to be a criminal. 

Once the war had begun, Obito went through a series of unfortunate events until Naruto reached out to him and helped him back.

Obito survives the war with Kakashi and team seven. Although, Kakashi disagreed, Obito gladly went to prison for three years until Kakashi, as Hokage, let him go.

Obito wants to find peace after everything that's happened.
