Each member of the crew, subjected to his malevolent experiments, emerged with newfound, dark powers that they have chosen to harness against their oppressor. Driven by an unrelenting thirst for vengeance, Slowshot now navigates perilous waters, not solely in pursuit of wealth, but with a singular purpose: to settle the score with the tyrannical Emperor and seek justice for the suffering his crew endured.
