Power Rangers: Biohazard Force
Chapter 1: The Creation of the Z-Virus.
The world was discovering the facts that Umbrella was in fact evil and was creating Viruses that made zombies. So, the S.T.A.R.S. and U.S.C.A.(?) had developed the Power Rangers group: The Biohazard Force. A group of people who were trained to defend all humans (good and evil, strangle.) from zombies. After a year, Umbrella discovered a form of the G-Virus called the Z-Virus. It created time traveling zombies who could be programmed to hunt ANYONE. So, Umbrella programmed 150,000 zombies to hunt all of S.T.A.R.S. members!
No one knew about it except Time Force (ironically a branch of The Biohazard Force) who gave the famous group of rangers the order to get the Original group of rangers of the Biohazard Force and get to the 150,000 zombies to kill all of them.
