Desertion of the Dinobots (1) - S2.E19

Both Autobots and Decepticons are facing tough times as they are in need of the element called Cybertonium. The Decepticons quickly get as much as they need, but the only way for the Autobots to get it is to rely on The Dinobots, who have been unaffected by all this. However, the Dinobots have been getting annoyed with The Autobots lately and leave them.
