This retro Transformers shirt has More Than Meets the Eye with Optimus Prime, Bumblebee and Prowl. Who's Prowl and why 1984? Prowl was the second-in-command after Optimus, at least in the Marvel Comics, and 1984 is when the TV series started. It was also the same time when Jamie, our resident pop-culture expert, found watching Transformers on TV was much more preferred to speaking to girls.
