S1·E14 Energon Grid

Megatron has taken yet another plan, to create three meteors from Unicron and propel them at Earth before the Energon grid has been completed. Dr. Jones notices Desert City's Energon tower has a fault, rendering the Energon Grid useless. Meanwhile, the meteors enter Earth's atmosphere, but one is destroyed by Rodimus, aided by more mysterious Blackout drones.
