Thundercracker

''"This is not what it means to be a Decepticon. While it is true that we want to conquer this world and Cybertron, it is through combat that we will succeed, not slaughter. After all, these creatures were never worthy adversaries." ''—Thundercracker

Thundercracker claims the skies as his arena. He looks down in contempt on those who cannot leave the ground — he considers them lesser beings. He will often attack the flightless beings below him for no other reason than to satisfy his scorn.

His superiority in this realm is the only thing he is sure of. Thundercracker is not entirely committed to the Decepticon cause, and even has some seemingly contradictory sympathy for the humans they terrorize. Fear of retribution from Megatron and the influence of his peers is usually enough to bury these doubts. Regardless, he needs constant reassurance from Skywarp and Starscream (which occasionally take the form of threats) that he's where he needs to be. Sometimes, his heart's just not in the job.

As the Decepticons begun to grow more aggressive and brutal, Thundercracker begun to have other thoughts. He later seemed to abandon the Decepticons and sought help from the Autobots as he was marked for death because of his "treachery." Later, he apparently sacrificed himself to prevent the Decepticons from nuking Los Angeles, California, an action that considered him an Autobot at Spark.

War for Cybertron
''Thundercracker served with Skywarp, Jetfire, and the former Sky Commander Starscream on a dilapidated orbital research station that once experimented on the powerful, but highly dangerousDark Energon. This made it a target for the leader of the Decepticons, Megatron, who wished to restart Dark Energon production in his plans to revitalise Cybertron. Megatron attacked the station and fought his way into the laboratory, and despite Starscream's attempts to destroy the remaining Dark Energon, Megatron withstood its destructive power and bent it to his will. His survival intrigued Starscream, who offered to serve Megatron in exchange for learning how to manipulate Dark Energon himself; Thundercracker and Skywarp fell into line. Jetfire declared them traitors and left to warn Zeta Prime. Thundercracker and Skywarp were prepared to give chase, but Megatron allowed the Autobot to leave, as he wished Zeta Prime to know his demise was coming. However, the Decepticon commander scoffed at the idea of being given what he could simply take from Starscream, until the one-time Sky Commander revealed that there was very little Dark Energon left on the research station, but he knew how to manufacture more, and that the ancient, long-forgotten Energon Bridge needed to be reactivated before they could do so.''

''Thundercracker, Starscream and Skywarp were sent the cliffs of Kaon, where they could make their way into the underground. Thundercracker commented with wonder that he had never travelled this far into Cybertron before, for which Skywarp labelled him as being boring as always. As they entered an underground energon reservoir, Thundercracker warned his teammates to avoid touching the flowing streams and waterfalls of crude energon, as in that state is was extremely volatile; Skywarp once again mocked his companion's thoughtfulness. Making their way out of the reservoir, the three fliers faced their first serious challenge when an Autobot cruiser appeared in a canyon they needed to travel through. The trio crippled the cruiser's weapons system, fought their way past theAerialbot squadron it launched, and moved into the ship. Defeating the ship's defenders, they then destroyed it by placing a detpack on the ship's power core. While Starscream and Skywarp busied themselves with glory hogging and relishing the battle against the Autobots, Thundercracker tried to keep them alive, using his Energon repair ray to heal their wounds. Deeper in the core, they encountered strange creatures the likes of which Thundercracker had never seen before. Eventually, they found themselves before the mechanism needed to restart the Energon Bridge, but Thundercracker's scans detected something very unusual about the machine. Starscream, tired of Thundercracker's readings and sensors, pushed his way past and injected Dark Energon into it without waiting for more information. Perhaps he should have listened to Thundercracker, as the machine activated its defense systems, revealing itself to be the Energon Bridge Guardian. The three Decepticons were forced to fight a desperate battle where the Sentinel threw heat-seeking fireballs at them, activated powerful energy beams and turned the floor into lava. Exploiting the machine's cooling down period, they were eventually victorious, and barely escaped with their lives when the Dark Energon infected the facility and reactivated the Energon Bridge, which sent its energon bouncing along satellites to Megatron's Dark Energon facility. Thundercracker remarked his amazement at this...but not until after Skywarp did. Y'know, TC, it's all well and good for you to be thoughtful and careful, but when Skywarp beats you to the punch in stating the blindly obvious, you might want to speed it up.''

''Shortly after the defeat of Zeta Prime, Iacon's guardian Omega Supreme gave chase to Megatron, though based on Megatron's attitude it was hard to tell exactly who was chasing whom at times. At one point, Megatron even ordered Starscream, Skywarp, and Thundercracker to attack the behemoth, if only to provide a distraction. The three apparently eluded him after drawing his fire (though Skywarp was batted entirely off Cybertron), however, as after Omega had cornered Megatron's team at an Autobot anti-aircraft terrace (or, depending on who you talk to, when Megatron tricked him into attacking them there), Omega's armor was breached by Megatron using the heavy guns, and Starscream led Thundercracker in shooting down the mighty Autobot, forcing him to crash land in a sub-level below.''
