Transformers introduced us to a level of tech we could only dream of in the 1980s because, well, Autobots and Decepticons are fictional beings from a faraway planet. While there sadly may never be a time when a sentient Optimus Prime walks among us, Hasbro and Robosen Robotics showed off the next best thing this week. A robotic Megatron that can transform from its bipedal form into a tank and back again whenever you command it to do so, joining a growing range of robotic Transformers and becoming the first Decepticon to join the line-up.
