Dr. Alice Krippin is the unintentional creator of the Krippin Virus. She is the main cause of the chaos around the world, although the mutation of the virus is out of her control.


Dr. Alice Krippin genetically engineered the Krippin Virus from the Measles virus as a viral cure for cancer in 2009. It is unknown what happened to Dr. Krippin herself when her creation mutated in the following year. However, it's highly possible she died during the outbreak or commit suicide out of guilt for taking part in destroying the world with her creation.


  • She is portrayed by an uncredited Emma Thompson in the movie for her minor role.
