The stark message on this Transformers t shirt is a play on the British World War II-era slogan "Keep Calm and Carry On." Black with a distressed print, the Transformers Keep Calm Hail Megatron T Shirt features the logo of the evil Decepticons and the phrase "Keep Calm and Hail Megatron" in large white letters. Megatron is the leader of the Decepticons in the Transformers universe. The Dark Emperor of Destruction, Megatron believes in "Peace Through Tyranny." Nice!
