Doctor Morpheus

Doctor Morpheus was a 19th century mad scientist from the city of Metropolis who invented a machine that could transfer the powers of animals into his own body, when he used it on himself, he was transformed into a terrible creature. He even tried to take over Metropolis, and at night, he would stalk the citizens and hunt them like prey. He caused a fire that nearly destroyed the entire city. Instead of trying to rebuild the city, the people of Metropolis just paved over the ruins and built over them.

More than a hundred years later, Doctor Morpheus is still alive, as his life span is apparently much longer in his mutated condition, and he comes face to face with Superman.
