Thrust in the original Transformers toyline is the name of a Decepticon who transforms into a red VTOL jet.
Thrust, Ramjet, and Dirge are part of a team dubbed by Transformers fans as the "Coneheads" for the way their animation models were drawn to make them visually distinct from the original Decepticon jets Starscream, Skywarp, and Thundercracker despite their toys being modifications of the same mold used to create that original trio.
Thrust's personality is that of a braggart who tries to psyche out his opponents with the roar of his engines, but is in fact a coward when it comes to actual battle.
In the cartoon, Thrust first appeared in the second season episode "Dinobot Island".
In the episode "The God Gambit" Cosmos collected data in space on a potential new power source, but was attacked by Astrotrain, Thrust and Starscream. Crashing on the moon Titan, the local priests worshiped the Decepticons as "Sky Gods", but rebels were able to reactivate Cosmos and call for aid from the Autobots. Optimus Prime sent Omega Supreme with Perceptor and Jazz. Astrotrain set himself up as the chief god of the moon and forced the natives to gather energy crystals. The trip to Titan drained Omega of most of his energy, but Perceptor and Jazz were able to gather enough crystals to reactivate Omega and defeat the three Decepticons. Vowing to not let the Autobots gain the crystals, Astrotrain set up a chain reaction destroying them. The Autobots aided the natives to escape the explosion and helped them settle in another area of the moon.
In "The Golden Lagoon" Thrust is the one that discovers the lagoon after Beachcomber left. He was also one of the nine Transformers to be transported to the giant alien world in "Child's Play". He attempted to warn the Insecticons about the Morphabots in "Quest For Survival," but was simply fired upon. In "Kremzeek!" he was responsible for dropping Kremzeek in the Autobot base.
Thrust also appeared in the The Transformers: the Movie. Among other roles he had in the movie, Thrust is most recognized as the first Decepticon run over by Optimus Prime as the Autobot Leader made his way towards Megatron.
In his last U.S. appearance, "Ghost in the Machine", Thrust and Dirge are among other Decepticons being punished by Galvatron for failing to stop a demoralizing assault by Starscream—now a ghost possessing the bodies of other Decepticons. Just before he and the other offenders are to be hunted down, Trypticon, the Decepticon city is possessed, trapping Thrust, Dirge, Runamuck and Runabout inside. He and Dirge liberates Trypticon from Starscream's control, just before the traitorous ghost was about to aid Unicron in destroying Cybertron.
In Transformers Animated, After Starscream went rouge and became an immortal loner waging war on his former leader, Megatron, he used his supernatural spark to construct a small army of clones with fragments of personalities of him. As every clone had the personality of an exaggerated Starscream trait, Thrust's was greed. But Thrust was never appeared in the series and as Megatron destroys all Starscream's Clones in Endgame Part 1, Thrust was destroyed too (as he was an inert Clone).
