This animated series offers a sleek update of the classic 1980s show about shape-shifting robots from another world--the virtuous Autobots and the evil Decepticons. In this second season, the Autobots find themselves in serious disrepair: they've lost the Key and lost respect in the eyes of humans in their adopted home of Detroit. As they try to turn things around, the action doesn't let up as the search for the all-powerful Allspark continues.
