The Prime Directive miniseries takes place after the Autobots had attempted to leave earth for a second time in a space ship called the Ark II, along with the defeated Decepticons. The Ark II was sabotaged, exploding in the upper atmosphere and sending all the Transformers falling back to Earth, deactivated. The story concerns the reactivation of the Transformers by a scheming entrepreneur and the results when things don't go as planned. Originally published in 2002, this previous version of the Transformers mythos ignited the imagination of Transformers fans new and old alike with artist Pat Lee's take on the Robots in Disguise. We'll be making efforts to ensure that previous iterations of the Transformers stay in print, so fans of all generations of Transformers comics will find something to their liking. No Transformers library should be without this essential collection.
