Shyleen Lao is an activist.
After Shyleen organized a protest, it quickly turned violent, leading to a nearby tanker exploding, causing Shyleen to be covered in liquid nitrogen. Doctors attempted to treat her, but ultimately gave up, causing Dr. Caulder to decide to help her, believing her to be worth the trouble. He had his subjects assist him as they tried to stabilize her temperature, succeeding thanks to Rachel Roth's empathic powers.
