Mr. Red
From Multiversal Omnipedia
Mr. Red, real name unknown, was an office worker in the Hive. Like everyone else in the Hive, Mr. Red became infected with the T-Virus when it got out. He became trapped in an elevator with several other Hive workers, including Ms. Black and Mr. Grey, where it is assumed he succumbed to the effects of the virus and became a zombie.
