Crescendo was a queen in a small country in the Middle East. The country was small enough to escape the notice of the old Roman Empire, but it was found by a group of Visigoths who were out plundering. They killed the people and destroyed everything. Crescendo survived and fought her way up from a slave to having wealth and power.
Crescendo survived through the years, but had no real purpose in life. When she learned about a barbarian who had come to the modern world she wanted revenge for what had happened to her and her land. She destroyed Aric's company Orb Industries and in the process killed Randy Cartier.
Crescendo was killed by Ken Clarkson, who skewered with a sword, and Aric who incinerated her weakened body, destroying her body, but not her soul. It was entombed in a pyramid. She escaped by possessing a human who entered the tomb and headed for America. Here she gathered some of Aric's foes and tried to kill him again. This time she was supposedly destroyed for good when she was run over by a bus.
