Music for the ArticleA Non Action Guy is a male who is not heavily endowed with a certain quality that's expected of males in shows; usually courage or combat ability. He's usually a sidekick; often to the Action Girl, or sometimes to an entire Good Guy Group.
Expect him to need occasional rescuing. This combo has the added danger of the audience seeing him as The Load, a role that can sometimes make him annoying.
The Non Action Guy seems much more likely to be played for comedy than the traditional female version of The Load as while women are not expected to kick butt (and thus those that do are exceptional) men often are and so a Non Action Guy's lack of ability is written as something to laugh at.
Often he'll either grow into a more action-oriented role, become ignored, or become the Chew Toy as punishment for his failure at trying to be dangerous.
