Billy the Kid is a Lucky Luke comic book written by Goscinny and illustrated by Morris.

Lucky Luke arrives at Fort Weakling, surprised at the deserted streets and the overly nervous welcome by the local hotel manager.

After these failed attempts, Lucky Luke decides to teach the people that desperados are not as bad as they pretend to be.

With the help of Belly, he pretends to turn into a desperado and begins to terrorize the town, including with a staged stagecoach attack and a bank robbery.

A duel is organized between the two in the main street, but the support of the population for Billy makes him break down, and Luke captures him.
