Solara

In the middle of a ruthless gang war which had kept him underground and away from his wife for a year, the infamous Yakuza leader Kazuya Morimoto discovered that his wife had given birth to a daughter named Reiko. Morimoto, insane with rage because his daughter was born in another man's house, poured gasoline in every room and burned his house, and family, to the ground. By the time the maid returned in the morning the house has been reduced to smoldering embers. She found Reiko in middle of the burnt structure completely unharmed and sent her to Cambridge. She learned about physics from her adopted father and became highly sought after for her research on cold combustion fuels. Unfortunately there was an accident during one of her lectures and everyone else died. Niles Van Roekel identified Reiko and considered her a prime candidate for his experiments. She was the daughter of a warrior and had a mythical resistance to fire. Without a second thought, Reiko agreed to join his top secret project. Source: Marvel Wikia
