Garbage In, Garbage Out

During Detroit's garbage crisis, energy from the Allspark creates a Transformer from a pile of junk. This Transformer, named Wreck-Gar by Angry Archer, causes problems for the city. Crossing paths with Ratchet and Sari (who are working to get Ratchet an attitude adjustment) and Lugnut (looking for Wreck-Gar's Allspark fragment), they all find themselves caught by Porter C. Powell's all-consuming micro-bots, made from Sumdac's nano-tech.
