Prologue: Stonal's Awakening

When an old foe from the Gems' and Bumblebee's past comes back to haunt them, Team Bee and the Crystal Gems must team up after twenty years. But can they take down this villain without Optimus and Rose to lead them to victory? And can Steven, Fixit, Sideswipe, and Strongarm take on a mission as big as this? They can only hope for the best.
