MR X (RE2)
From Create Your Own Story
After the initial outbreak, Umbrella scrambled all their resources to recover the G-virus that one of their top scientists, William Birkin, had been working on. Not only did they send in one of their best U.B.C.F. teams, they also sent in one of their new Tyrants, known as Tyrant-00 commonly referred to as Mr X.
Mr X is smarter than the rest the Tyrants (with exception to Nemesis) and also more humanoid looking. He is also incredibly strong and is able to tear a car to shreds in seconds.
