Skyquake was Dreadwing's twin. He is so loyal to Megatron, that when he emerged from stasis, he refused to obey orders from "Lord" Starscream, even though Starscream told him that Megatron had parished. After he died by the hand of Bumblebee, he was re-awakened into a terrorcon by Starscream with a shard of dark energon.
