The third season began on March 14, 2009 with the three-part premiere, "Transwarped", and ended on May 23, 2009. This season following the events of "Transwarped" focused on the Autobots' attempt to reach Cybertron in order to warn the Autobot High Council of Shockwave, who has been masquerading as Autobot Intelligence Officer Longarm Prime. Meanwhile, Megatron, Starscream, Shockwave (who replaces Blitzwing as a main character), and Lugnut plan to use the colossal Autobot Omega Supreme for constructing clones of him (dubbed as Lugnut Supremes, as they appear similar to Lugnut).
