Checkerflag had used to be in the Wreckers before the group and its members all died. After that, he had joined the Autobot Marines with Ironbulk and Primal in 2037, or sometime in the Early 2030's. Checkerflag had faked his death a long time ago. He hid on Earth Y in secret after the horrible event that caused the Extinction Universe to die out due to Unicron and Pac-Tron messing with it. After hiding on the Earth of that Realm for decades, he fought Speedemon. Speedemon and Checkerflag became rivals and nemeses.
