This is the suggested order that you read the stories in, so you don't get too lost. A NOTE: It is not necessary to read the Original Series stories, as they have no bearing on what's currently going on in Earth Prime. However, Ground Zero, the final Original Series story, was what relaunched the series and was where nearly everyone on T3M got on board when the relaunch happened, so you may want to read that, especially since repercussions from the story are still being felt (or have yet to be felt) in Earth Prime.
