BtS stands for Bolt the Superdog, and when used in this way it is referring to ArtistIssues' series of Bolt Alternate Universe fanfics. This AU is modeled after the Bolt TV Show's plot. It is centered around Bolt, who actually has super powers, and his Person, Penny, who really is trying to rescue her father from the feindish Dr. Calico and his evil organization before the cat-loving maniac can conquer the world. Mittens and Rhino also make appearances as Bolt's allies. ArtistIssues began the series with Bolt the Superdog: Shocking and plans on writing at least four more.
