The Biker Mice's Mars mission continues to unfold in the next octane-pumping blockbuster from hotshot writer Melissa Flores (Power Rangers Prime) and full-throttle artist Daniel Gete (Skin Police)! As Vinnie, Throttle, and Modo transport the renegade scientist—who may hold the answers to the Plutarkians' Mars attacks—across the desert on their way back to Brimstone, they find themselves under attack from a deadly subterranean menace. Meanwhile, at the spaceport, a classic Biker Mice villain arrives, making his series debut in style. And when HARD ROCK comes to town, the motorbike-riding mouse bros find themselves caught between a hard place and, well . . . him!
