Introduced in 1984, the Transformers brand took the world by storm with its compelling saga of the Autobots versus the Decepticons. The innovative "Robots in Disguise" resulted in a tremendously successful toy line from Hasbro and Takara, comic book series, television program and an animated feature film. More than 20 years later, a new generation has discovered the excitement of the Transformers brand and its legendary characters, including the two leaders of the opposing sides: Optimus Prime and Megatron. Today, the franchise features a popular toy line, an animated series on the Cartoon Network and a chart-topping comic book series from IDW Publishing.
