Darkwing

Darkwing was a Cybertronian and one of Blackout's soldiers. He and his brother Dreadwind served as Blackout's guards during his trip to Dragku.

Much much later, he and his brother joined Starscream in his failed attempt to overthrow Blackout. He appeared out of a portal along with Thundercracker, Skywarp, Dirge, Thrust, Ramjet and Dreadwind and then was completely forgotten about.

Far Future
In the far future, Dreadwind and Darkwing served as part of Blackout's empire. They accompanied Blackout to the planet that Kakamu ended up living on, and explored Kakamu's base. Once finished, Dreadwind and the others returned to The Sabre.
