Starscream was a major antagonist of the Transformers Marvel Comic strips.

Marvel Comics
Formally the political figurehead of the city-state of Vos, Starscream sat ill in his position in the Decepticon ranks, but never posed a real threat to Megatron in their early days, delivering only the occasional snipe or criticism that the Decepticon leader would be quick to put down with a show of force. Deactivated following a battle with Omega Supreme, Starscream spent several years in stasis, but once reactivated, he quickly ingratiated himself with the new Decepticon leader Ratbat and through information gained from him was able to obtain the cosmic power of the Underbase.

After going on a rampage across Earth and slaying dozens of Transformers, Starscream himself was destroyed by the Underbase's unstoppable energies, but his corpse was recovered and brought back to life by Megatron as a mindless Pretender. Regaining his faculties thanks to Ratchet's sabotage, Starscream joined Scorponok's Decepticon cell on Earth, but his new powers led him to be feared and hated by his fellow Decepticons, even more than usual, and he proceeded to break away and help Shockwave start a Decepticon Civil War. Teleported to Cybertron to face the threat of Unicron, Starscream fled the planet aboard the Ark, and was knocked offline again when it crashed to Earth for a second time.
