Baron Ashura fell in love

Before Ashura became their current self, they were originally a separate man and woman who fell in love. But their love was forbidden and when the affair was discovered, they were given a horrible fate; they were both mummified and buried alive. After many years the cave collapsed and a piece of rubble crushed the man's right side and the woman's left side. Eventually the tomb was found by Dr. Hell and the bodies were discovered. The Doctor had the bodies sewn together and named the new lifeform Baron Ashura.
