The Transformers: Stormbringer #4

Though Bludgeon and his rogue cult of Decepticons have been defeated, the newly re-enervated Thunderwing remains active, returning from his devastating rampage on Nebulos with Cybertron locked firmly in his sights once more. There, Optmus Prime and the Wreckers brace for impact, unaware that Megatron has his own doomsday scenario in the work, and the clock is running... Out of control, acting on pure, devastating instinct, THUNDERWING descends once again on CYBERTRON, with only a skeleton force of Autobots under the command of OPTIMUS PRIME to oppose him. While JETFIRE searches frantically for options, uncovering more mysteries in the process, the countdown to the total destruction of CYBERTRON continues. The line has been drawn, and-one way or another-it all ends here.
