The man and his wife were government scientists who worked on biological experiments. At some point, they had a son, Maxwell Lord.
One day, the couple tried to report a weakness in the safety system, but their employers wouldn't listen and left the system as it was. Two months after this, despite Max repeatedly warning his parents and their employers, a virus made it into the man and his wife's protective suits. The couple were subsequently killed when their internal organs and later bodies melted.
