Far more impressive than anything Michael Bay could cook up, factory owner Li Lei is making life-size Transformers out of scrap metal on the outskirts of Shanghai. Enlisting the help of workers, Lei and his team have been banging together bootleg versions of Optimus Prime, Bumblebee and other potential trademark infringements.

Lei says his hobby has become a lucrative venture. He’s been renting and selling his Trashformers, with orders increasing ahead of the release of Transformers 4: Age of Extinction.

Amazingly, he’s not the first to have come up with the idea; Chinese “repairmen” and some mega-fans in eastern China beat him to the punch. Oh, well. Let the Trashformers battles begin!
