Fearful asymmetry
Richard Belzer is best known as the acerbic Detective Munch on Law and Order, but the character debuted in an entirely different show, Homicide: Life on the Street, and has appeared as Munch in more continuities than any other fictional character on television. He didn't just invent crossovers, man... he was the crossover, personified! What will happen to the Multiverse in his absence?!
