I've been watching One Piece with my roommate, and I've noticed how many of the stories hinge on waiting on Luffy to come and save the day. Then I wondered... it would be really cool if there's a leader of a group of heroes who is completely useless compared to the rest.. and yet, he's still the leader because he tries despite not being "the best". That would be an interesting twist on the leader mechanic.
Wait.. that's Jacuzzi Splot, the shy crybaby that never gives up on his friends. Nevermind XD
