Bulkhead and Arcee, with Miko tagging along, are sent on a reconnaissance mission to investigate a bizarre energy signal in the desert. They discover that the signal is coming from a Polarity Gauntlet, a weapon that manipulatesmagnetic fields. However, they soon come into conflict with Breakdown and Airachnid, who both want the Gauntlet for themselves. In the end, though, Arcee and Bulkhead are successful while Breakdown returns to Megatron empty handed aside from Airachnid, who rejoins the Decepticons.
