None.

This film is quite violent for an old Superman cartoon which is approved for families.

A car crashes into a window. There is a violent shootout and a car chase.

There is a kinda violent gunfight at the bridge to an airport. Several people are hit, but we see no blood and death.

A woman is almost shot by some people.

A car crashes into an electric tower, causing it to later smash and burn a small control room.

"Fool" is mentioned once.

Not to count the opening credits and Superman's introduction, this film starts at a drug store. But nothing is taken.

Along with the amount of gunfights, a woman falls on the turning mechanism of a bridge, and becomes unconscious for a while when the massive gear in the turning mechanism is slowly creeping up on her.

Despite this Superman cartoon being meant to be watched by families, the amount of violence may be kinda intense for very young children.
