This is a list of Decepticons from the Transformers fictional universe and toyline. The alternate modes of Decepticons are usually military vehicles, to contrast with the civilian vehicles favored by the Autobots.
Seeker was a term originally used in Hasbro's promotional materials to refer to the Decepticon Jets of the same mode. Only Starscream, Skywarp and Thundercracker were named during Season 1 of the animated series. The name Sunstorm was given retroactively by toy-distributor E-Hobby to the previously unnamed yellow/orange Seeker and Purple/Silver is Slipstream. This was later picked up by comics publisher Dreamwave Productions. Ramjet, Thrust, and Dirge (introduced in Season 2) essentially used the same mold as their Season 1 counterparts but with small modifications, and because of this, they are also known as the "Coneheads".
