Stoker's Gambit[]

A Salt on Detroit[]

The Biker Mice are trapped in Detroit by their old archenemies Limburger and Napoleon Brie, who plan to re-conquer Chicago with the Regenerator. In addition, our heroes have other things to worry about: Has Stoker switched sides? Meanwhile, Charley and Carbine are searching for the Biker Mice, but they meet an unknown mouse from Stoker's past.

Best Laid Plans[]

The Biker Mice have big problems: Stoker has been kidnapped by Rump and the Catatonians.
