History
Megatron put Soundwave in command of the Kaon Prison Complex. The prisoners there are loaded onto Decepticon Dropships. The dropships transport the prisoners from any battlefield to Kaon Prison, where they are either escorted to cells, executed, or sent to 'recycling', where the prisoners are thrown into a strong current and crushed in a masher.

During the Decepticons' assault of Iacon, Soundwave raided an Autobot outpost, taking several prisoners and most of the outpost's energon supply. When Optimus and his team arrived, Soundwave spotted them and ordered a duo of rocket troopers to attack and destroy them, while he and the other Decepticons left in a dropship for Kaon with the energon and prisoners.
