Thundercracker is one of the Decepticon seekers and a member of the Decepticons.
He was awakened in 1984 on Earth after laying dormant and deactivated over four million years in his new Earth mode called the F-15 eagle jet. He shared the same Earthen appearance as Starscream and Skywarp and is usually allied with them during the attacks and battles with the Autobots.
Often chafing under Starscream's self-importance and glory seeking, he seemed to dislike Starscream and exploited reasons to undermine his authority, such as letting their former ally-turned Autobot Skyfire destroy one of their secret weapons merely so Starscream would get the blame.
He was voiced by the late John Stephenson (who also voiced Mr. Slate from The Flintstones) in Season 1 and Wally Blur in Season 2.
"Comtemptuous of anything that cannot fly. Not totally convinced of the Decepticons' cause, but they persuaded him to continue battling the Autobots. Flies at speed up to 1500 mph.. produces controlled, deafening sonic booms that can be heard for 200 miles. Equipped with powerful drone rockets & incendiary gun. Doubts about cause sometimes impede effectiveness."
Transformers: The Movie
Thundercracker made his final appearance in Transformers: The Movie, once again as one of its minor villains. He was among the few Decepticons present in the battle of Autobot City in their assault before being gunned down by Optimus Prime, who headed on to fight Megatron. With the Decepticon's defeat, an injured Thundercracker fled with the rest of the Decepticons & hitch a ride to Astrotrain. While on their way back to Cybertron, Astrotrain complained about the heavy load & requested to lighten the load. After Starscream argued with the rest of the Decepticons to claim the new Decepticon leadership, Bonecrusher suggested a fight of the fittest in which everyone agreed. Thundercracker was among the few casualties from the fight & he, alongside Megatron, Skywarp & the Insecticons, were dumped out of Astrotrain.
His misery was put to an end when Megatron encountered Unicron, whom he made a deal with. Megatron was then turned into Galvatron, which led Thundercracker to be reformatted into Scourge, with the Insecticons being reformatted into his lookalike minions known as the Sweeps.
- Thundercracker's classic colors would later appear as Starscream's Super Mode colors in Transformers Armada, in which Starscream would mention that he looks like Thundercracker.
- In the video games, Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS/Wii U, one of R.O.B.'s alternate costumes is based on Thundercracker's classic colors.
