The 100% cotton Transformers Decepticon Kids T-Shirt is for the infant who may or may not be a 'Robot in Disguise'. You see, the Decepticons were getting their butts handed to them by the Autobots and since the Autobots are trucks/cars and the Decepticons tanks/aircraft, they decided to beat the Autobots at their own game. They now transform into BABIES! It allows them to infiltrate human society in order to effectively find Energon Cubes. If you don't follow any of that, that's okay. Just know that the Transformers Decepticon Kids T-Shirt is one great t-shirt!
