I find that most young heroes are too stereotypical now. They usually fit this description,
cocky, confident, never ugly or disfigured or have any quirks that could be considered abnormal except their powers/abilities and they always get told how they have loads of potential and always go through the apprentice beats the master routine.
It soo annoys me when you get a young "Robin-like" stereotype who manages to win against their teacher who has been training for years and years before them and should defeat the younglings in their training sessions for the first 20000 bouts.
