(Capcom's primary storyline)
Greg Mueller was an Umbrella researcher who rebelled against the company.
Greg was assigned to the Umbrella R&D Center in Raccoon City. During his time there, he was involved in the events surrounding the Arklay hospital and the illegal human drugs trials being conducted there. At one point, he began researching into the experimental "Tyrant"-class B.O.W., which he attempted to develop on his own. The fruit of his work was "Thanatos", a seven-foot-tall killing machine. Unlike other Tyrants made that year, Thanatos was a very intelligent, strong, and agile creature.
However, when Umbrella began plans to mass-produce the Tyrant, Greg became furious, believing that this would take away from the individuality and uniqueness of his subject. Like many Umbrella researchers, Greg viewed his creations as works of art, and not mass production weapons as Umbrella intended, refusing to help them any further.
Due to his rebellion, Greg was marked for assassination by Umbrella, who sent a U.B.C.S. team to assassinate him and retrieve a blood sample from Thanatos. Anticipating this, Greg intended to have Thanatos eliminate his would-be assassins. Thanatos largely achieved this, quickly killing off a UBCS squad. However, a UBCS Monitor, Nikolai Zinoviev, ultimately managed to shoot Greg with a silenced 9mm pistol from above the ceiling in the Second Hall, and a large amount of blood spilled from his neck, death being instantaneous.
"Too much growth weakens an organization, which what should be important becomes overshadowed by greed. Mass porduction?! Ridiculous! [...] One masterpiece is enough!"
"My apologies for this place being so... ectic. I have been monitoring your progress from here. I am grateful for your assistance. Daylight is it. The only resource against the T-virus. I cannot give it over to Umbrella. They're the ones responsible from the catastrophe which has befallen the city. In retrospect, the entire "t" project was a total disaster. Brute force should not be the only criteria for a weapon. It must also be beautiful, unique, and God-like. You will also assist me. You're going to play with my ultimate creation."
Greg is unlocked after completing the scenario Decisions, Decisions on VERY HARD difficulty. His set costs 10.000 points. Greg is a George-type character who starts each game carrying an Anti-Virus (L) in his inventory, and starts in FINE status. Alternatively, he is already unlocked in File #2 and can be purchased for a much cheaper price (1.000), and can be transferred to File #1 via the Data Convert. In File #2, he instead starts a scenario with three Anti-Virus pills.
Greg has the largest vitality of any playable NPC in the outbreak games, excluding the Mr. and Ms. Colors characters, of between 3600 and 4000 HP. Greg has an average infection rate of 1.21% per minute, a movement speed of 0.81, and a damage multiplier of x0.85.
