The recurring female character Viper tends to wear somewhat form-fitting clothing; she is also fairly flirtatious towards Jackie. In some episodes male characters are seen in boxer shorts, which is played for comedic effect.

Being a Jackie Chan inspired series, there is a considerable amount of martial arts based action. However, the majority of fights feature the heroes defeating the villains while causing a minimal amount of harm, usually causing more humiliation than injury. There are also sequences of the heroes battling against Demons and other supernatural creatures, who usually disappear upon defeat.

Some episodes, such as "The Demon Behind" and "The J-Tots" feature bathroom humor.

Little to none. In one episode Jackie is bitten by a snake and starts to exhibit drunken behavior; this is a nod to Jackie Chan's film "The Drunken Master."

The series does feature supernatural creatures-demons, vampires, etc.-who might be frightening to younger viewers. Characters are occasionally shown to be in peril or suffer harm, though rarely is it serious. Various transformation sequences might be frightening or disturbing to some children. The villain Shendu possesses several characters over the course of seasons one and two.
