Starscream

Starscream is the toadying lacky of Megatron, who is either his most loyal servant or his mortal enemy. Starscream will often lead the Decepticons into battle in the name of Megatron, but is constantly plotting his downfall. Megatron often sees right through Starscream's feeble plans but lets him get away with most of them because they amuse him so much. Starscream is a reasonably  powerful foe for the Autobots, (apart, of course, from Optimus Prime). However, even some of the weaker Autobots can still take him on in one-to-one combat and emerge victorious. Starscream is a coward at heart and will often flee battles even if he only takes minor damage.

Because of this cowardly streak, Starscream's roles in the Decepticon's incursions on Earth are noticably minor. In the first incursion he helped to free Megatron but fled the planet soon afterward. In the second incursion he helped to resurrect Megatron but did not participate the final battle. He did, however, attack Optimus Prime with his chums and aided in his death, but in the process he lost an arm and was severely wounded. After the resurrection of Optimus Prime and the death of the Fallen, Starscream aided in Megatron's recovery and helped to capture Chicago. He attacked some Humans in the street but one shot a grappling hook into his eye. Furious, he attempted to escape, but the Human lodged a boomstick into his other eye and blew him up. Poor guy.
