Jazz

Jazz was an Autobot that fought alongside Optimus Prime in the Cybertronian Civil War, and was First Lieutenant of the Autobot forces during the First Decepticon Incursion. Jazz crashed to Earth with Prime, Ironhide and Ratchet to come to the aid of Bumblebee, who had happened upon the Allspark, Megatron and a Decepticon Army.

Jazz scanned a cool car (for some reason) and joined the fight with the Decepticons, attacking Brawl before buying Optimus time by assaulting Megatron himself. After being tossed around for a bit, Megatron finally had enough of Jazz shooting at him and tore the brave Autobot in half, throwing his pieces away randomly into the street. Shame.
