Rick and Morty face a foe unlike any they've seen before. Well, it's basically Jerry, but he's huge, fast, vicious, and... naked? Rick has the perfect solution: a giant mech fighting robot, perfectly designed and calibrated to take on the Jiant horde-but it needs a puny, socially isolated, 14-year-old pilot. Oh, we've got one! Summer, Morty, and his charming new friend Rowan navigate this violent post-apocalyptic world, where they still have to go to high school and Rick seems oddly invested in upgrading the mech with stylish new features.
