The Leaf's Greatest
When I found that this there is a missing team, I found out that there is a secret team called "The Leaf's Greatest". Members for it are purely characters that needs to be unlocked. You need The Third Hokage, Tsunade and Jiraiya and select these 3 characters on Heroes Mode then you should unlock the team.
