Fifty years ago, Maria Robotnik's parents made the hardest choice of their lives-entrusting their fragile, sickly daughter to her grandfather, Professor Gerald Robotnik, when they could no longer care for her. On the orbiting space colony ARK, Gerald promises Maria a brighter future, swearing to protect her and give her the life she deserves. But as Maria dreams of gardens and starlight, Gerald is driven by a vow that grows heavier with every passing day: to defy the limits of science, of nature, even of morality itself, if it means saving her. What begins as a story of love and sacrifice becomes the foundation of a project that will change history forever. From Maria's laughter in the halls of the ARK to Gerald's midnight experiments in the shadows, a legacy is born-one that will bring forth the ultimate life form. At its heart, this is the story of a grandfather's promise, a girl's fragile light, and the origins of Shadow the Hedgehog.

He may have put his past behind him, but his past is also G.U.N.'s history ... and those who fail to learn from history are doomed to repeat it. Shadow was created to be a cure and forced to be a weapon, but now he has to forge a new path beneath the shadow of Space Colony Ark and the spectre of White Space. Meanwhile, G.U.N. is suffering a dire public image crisis, and their actions force Shadow to reckon with his past and Maria's legacy once again. Can Shadow find a new way to fight for humanity in spite of G.U.N.'s machinations, or was he destined to be a weapon all along?
