Transformers: Cybertron Adventures
Thundercracker is sent to place homing devices on escaping Autobot ships so that Trypticon can shoot them down, but Trypticon fails to shoot down the Autobot Council Ship before being sabotaged and rendered vulnerable by the Autobots。
With the rest of the Decepticons scattered throughout Iacon, Megatron is left alone to fend off the Autobot siege against Trypticon。
Megatron realizes that Trypticon will be destroyed, and salvages Trypticon's data core before Trypticon is destroyed。
The Decepticon campaign ends with Megatron revealing that the salvaged data core contains the secrets of Dark Energon, and thus the Decepticons still have the advantage in the war。
