Pocketbot

Pocketbots are small insect like drones that Professor Sumdac created. What their exact function was is a mystery, however they do posses a tiny cutting laser. The pocketbots were a bit of a failure however as Sumdac could never get them working. When Megatron revived, he managed to transfer some of his energy to one, taking control and using it as a spy. He slipped it into Sari's backpack upon learning she was heading to the Autobot base. Megatron used it to search for the All Spark, but when the search ended with failure, he used it to transfer some energy to the factory's control station, allowing him to take control. After Bumblebee destroyed the console, Optimus found the pocketbot. It escaped from him, only to be crushed by Bulkhead
