*takes a deep breath* THIS IS WHY WE CAN'T HAVE NICE THINGS!
Now that that's out of the way ... As you can see, this is Thomas The Tank Engine -- the Transformer. It takes three tank engines to form this mighty beast, who combine when their synchronization rate is at 200%. Through hard work and guts, they will have the power to destroy all evil trains that threaten humanity! Not only that, but this burly beast has FOUR FACES! Clearly, its manliness far surpasses the likes of mortal men and goes through to the heavens itself. Now all we need is a guitar accessory for the tank engines to fight off the evil space locomotives or else all the world will become orange juice!
This mighty transformer of legend can be yours if you search Yahoo Japan auctions or eBay, but it will be a difficult journey and I will commend you if you attain this holy grail of toys and Transformers everywhere. See if you can name the many mecha anime references I used in the first paragraph!
