The Cosmo Rangers inherit a machine designed to save the world, then discover the world doesn't want saving anymore. Space opera built on the skeleton of a 600-year-old legend that nobody remembers the same way twice. You're watching people try to be heroes in a system that has already decided heroism is a luxury it can't afford.
Six centuries have passed since J9 defended the Solar System, and now chaos reigns across the galaxy. Lawlessness spreads through the fragile government while an alien armada emerges from the depths of space, threatening everything. Two former allies, Digo and Schutecken, decide the only solution is to assemble a new force: the Cosmo Rangers, a reinvented version of the legendary J9 unit. What starts as a small strike team quickly spirals into something far larger. Billy the Shot, Jumping Sama and Lila the Immortal Butterfly join forces with others, transforming their group into a full-scale military operation. As they chase criminals across the asteroid belt and beyond, the Rangers find themselves bearing the weight of an entire government's survival on their shoulders. Riding Cosmo Bikes that merge into the giant robot Baxingar, the team takes on a solar system slipping toward anarchy.
