Parents need to know that there's plenty of violence in this cartoon series about a boy involved in a battle between good and evil. Since he has a powerful robotic arm, expect lots of hand-to-hand combat (punches, kicks, hurling enemies into walls) and occasional firepower. But it's usually the robotic enemies who suffer the most -- human characters' injuries are rare and short-lived. There's not much else to worry about in this series, but it doesn't have obvious positive messages, either.

Families can talk about violence in cartoons. Is it different from live-action battles and fights? How? What if more of the victims were human instead of robots? Families can also talk about responding to change and adversity. How does Marty react to his new role and responsibilities? How would you feel in his place? Kids: Have you ever been put into a role or situation you didn't expect? How did the experience change you?
