Stormbringer issue 4
Synopsis
Thunderwing reactivates and returns to Cybertron. The Predacons prepare to bombard Cybertron from orbit in order to destroy Thunderwing once and for all, though Razorclaw is reluctant to do so unless absolutely necessary. The Predacons fight alongside the Wreckers until they reach a safe extraction point and the Thanatos' Starblitz torpedos are armed. However, Jetfire learns that the more Ultra Energon Thunderwing uses, the quicker it runs out. Optimus Prime begins blasting Thunderwing until he runs out of energon and dies, prompting Razorclaw to cancel bombardment with one second to spare.
Optimus then heads for Earth onboard Ark-27 after learning that more ultra energon is located there, which is interesting as he had just received a call from Prowl on Earth asking for help.
