This Transformers t-shirt shows Optimus Prime posing with retro 80s colors and shapes. Optimus Prime made his debut in 1984 on the classic Transformers animated series. Prime is the courageous leader of the Autobots. When Prime isn't battling the Decepticons in robot mode, he is more than meets the eye when he transforms into a heavy-duty cab-over truck. In either form, Optimus Prime is fighting to save the galaxy.
