The Rise of Scourge is an original English-language manga written by Erin Hunter and Dan Jolley, and illustrated by Bettina Kurkoski as part of the Warriors series.
When other cats ask him about it, Tiny lies and says that he ripped it out of a dog's mouth after killing it, in an attempt to impress them.
The story spreads, and soon two loners, Bone and Brick, come ask him to help get rid of a dog that is keeping the stray cats from a dumpster full of food.
Later, Scourge is asked to help drive away a gang of forest cats that are causing trouble for the strays.
Scourge is treated as a sort of leader among the city cats after the incident, and he becomes more of a dictator to them, though he remains discontent.
Once he strikes out on his own, though, he renames himself Scourge and vows to take revenge on the wild forest cats who once attacked him.
