Last Stand of the Wreckers
Skyquake was the one to lead the Decepticon assault on Garrus 9, the Autobot maximum security prison planet. Decepticon victory seemed assured, at which point the murderous loose cannon known as Overlord showed up and immediately assumed command of the assault for his own agenda. Despite being unnerved by Overlord's arrival, Skyquake refused to give up his leadership position and was dead-set in capturing Garrus 9 for Megatron as he'd been ordered. Mildly disappointed, Overlord shot Skyquake in the back as he was walking away, killing him instantly. Standing over the smoking corpse of their former commander, the remaining Decepticons knew they had no choice but to follow Overlord from now on.
