None. Some characters are implied to have romantic interests in one another but this is never explored.

Some mild violence including airplanes and aircraft explosions. (No one is believed to be harmed.) Very little blood in this show.

Some characters drink/smoke socially. In one episode, Parker steals a bottle of Champagne intended to be used to launch a ship. He and another character drink the Champagne and Parker is shown to be drunk afterwards.

Some action violence may be a little intense for extremely young children. The Hood may scare some young children.
