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!
