Any show that features action for the most part, since the 50s on up, has always had the one character who is either appointed or the de facto leader of the group. For the most part they're usually the most balanced character, can do no wrong, but occasionally they're written as jerks, or somewhat self-serving and annoying, yet still have leadership qualities about them. Do you have any favorite "leaders" from cartoon shows from over the years? I just recently started watching that Sushi Pack cartoon on CBS now, mostly because it's written by the old Tiny Toons/A! staff, and the leader of that group known as Tako cracks me up as he's pretty much a flawed character that acts for his own selfish whims at times, gets back sassed by everyone in the group, but when push comes to shove, can save the day.
