Having taken one of Megatron's bases, Prowl follows the former Decepticon leader through a flashback doorway, which he hopes will allow him to find more troops. Prowl finds himself in New York in 1988 during the Underbase affair. He realises Megatron has possessed Snap Trap to try and spare the Seacons and recruit them in the present day. Prowl intervenes, and knocks the Decepticon out. After overseeing the Seacons' destruction, Prowl awaits his own deactivation at the hands of Starscream, after which he wakes up back in the present.
