The Transformers were basically designed as toys before they were designed as big movie stars, so it's only natural that you can buy every one of them in details toy form. But no toy you can buy at Wal-Mart can hold a candle to this amazing customized Optimus Prime model.
Modder Crefigz took the standard Hasbro Optimus Prime toy and took it to the next level, adding an insane level of detail. It's the sort of thing you'd display on a shelf rather than play with. And it can be yours! It's for sale on eBay right now, so if you're interested, get to bidding! Oh, but be warned: it's currently at $710. Yikes.
