Sideswipe is an Autobot warrior, who is trusted by Optimus Prime.
Sideswipe is always happy in the heat of battle. He's also a bit of a smart-aleck, and this tends to cheese off his comrades. Very competitive, he'll do anything to win.
War for CybertronEdit
As part of Optimus's plan to rescue Zeta Prime, Sideswipe was imprisoned in Kaon with the other Autobots. Soundwave sent the prisoners for "recycling", but Air Raid rescued them just in time. Optimus, Sideswipe, and Bumblebee then fought their way in and out of the prison in order to save Zeta, to Sideswipe's enjoyment. Despite being teleported into prison again, courtesy of Megatron, Optimus used his energon axe to get them out, leaving Sideswipe impressed. The squad of Autobots freed the captured Air Raid and all the other prisoners, and then, after blasting through more Decepticons and barely making it over a floor under assault, intended to free Zeta Prime as well... but found him being guarded and tortured by Soundwave and his minions. After defeating them, Sideswipe accompanied Optimus and Bumblebee as they brought the deceased Zeta to the Autobot High Council, and witnessed Optimus's promotion to Autobot leader.
After Trypticon attacked Iacon from orbit, Sideswipe was one of the first Autobots able to run recon on the damage and look for survivors. While traveling through the debris he was contacted by Ratchet, who was nearby and in need of help. Sideswipe quickly changed course to chase after the medic, finally finding him damaged from a brief confrontation with Megatron. Later, as Barricade infiltrated Iacon, Sideswipe gave the Decepticon a brief chance to surrender before opening fire. Sideswipe was badly damaged before Barricade fled the scene.
