Thundertron is the leader of the Star Seekers. The massive, peg-legged leader of the Star Seekers and captain of the Tidal Wave, Thundertron claims to be "the mightiest free booter on the spaceways." Aside from being a merciless pirate, the destruction of his home world by Cybertronians has given him an unquenchable hatred and desire for revenge. He vows to hunt down and slaughter anyone who come from Cybertron, and is equally brutal with anyone else who comes in his way.


Transformers: Exiles

Sensing the energy trail of a Cybertronian ship, Thundertron had his ship land on Velocitron. He quickly questioned the planet's leader if there were any Cybertronians there. She said there were none, but the leader's refusal to divulge where they were, her insolence in asking the fault of being Cybertronian, and her rival's insistence that she was Cybertronian quickly made Thundertron lose his temper and ordered his crew to attack. Following the energy trail, they traveled through a space bridge to Junkion, where he found not only the Cybertronian ship, but another. While the Cybertronians were fighting each other, Thundertron met with the leader of the locals. He quickly forced the Junkions to repair his ship and attach a space bridge to it. He had two crew members show the Junkions they meant business by killing one of them. As soon as the space bridge was attached, Thundertron ordered the Star Seekers to attack the Cybertronians.

Transformers: Retribution

Some time after the battle on Junkion, Thundertron and the Star Seekers engineered a ruse to trap the Decepticons and to wipe out the Nemesis with the Requiem Blaster. Taking advantage of the Blaster's high energy consumption rate, Megatron and the pirate leader came to a stalemate in hand-to-hand combat while the Nemesis overwhelmed the Tidal Wave, forcing the pirates into a retreat.
