Unlike his fellow Decepticons, Swindle doesn't really care about the fate of the universe. No, the war for Cybertron is actually a pretty good business opportunity! While he's acting as the leg of Bruticus, Swindle thinks only of what he'll get in trade for Autobot bodies he's stomping once the current battle ends.
Starscream tasked the Combaticons with intercepting an Autobot transport. Onslaught tasked Swindle with patrolling the area to take out any scouts who might give away their operation. Though they successfully destroyed the bridge, the diverted transport still had plenty of anti-air defenses to keep Starscream's aerial forces at bay, so Swindle was sent in. Driving underneath, he destroyed the transport's wheels before taking on a pair of titans. The transport converted to a flight mode, so Swindle grappled on board and started taking out the transport's anti-aircraft cannons by blowing up their ammo. Working his way around to the other side of the ship, he discovered that the Autobots had destroyed the controls for the shields so he couldn't blow them up, so instead he had to join the other Combaticons on their dropship so they could take it out. The team combined into Bruticus and stormed through the rest of the Autobot defenses, though in the process they damaged the transport so badly that it crashed. The enraged Starscream ordered the Combaticons arrested.
Swindle and the Combaticons were later freed once Megatron was resurrected and defeated Starscream. They were aboard the Nemesis as it pursued the Ark and Swindle took part in the assault on the Autobot ship's engines as part of Bruticus. The giant took out many Autobots in its way before he was taken down by the combined efforts of Jazz and the Aerialbots before floating free of the Ark.
