Chrysalis is a robot hero created by Dr. Gerard Yves Martet at his laboratory in Marseilles, France. Marter harbored anti-semitic views who blamed the jewish people and other imigrants for the corruption of France. He designed Chrysalis to appear friendly and liberal but inside her shell was a swarm of genetically engineered butterflies that carried a deadly virus. Martet planned for his creation to enter large immigrant districts in France and release the insects.
Gerard found a way to get his creation recruited into the Global Guardians, but he died soon after. Chrysalis served loyally with the Guardians but deep down she is aware of her programming.
