Gary Murray

Dr. William L. Flemming was a research scientist at the Lobito Physics and Chemistry Lab and the co-creator of Project Pythagoras, along with Hans Davis.

He was originally thought to be Gary Murray, a lab assistant who escaped from Leone's men. Snake first met him in the Control Room after being contacted by him on the Codec. He told Snake that Dr. Flemming, who Snake was searching for, was located in the Residential Area. This ended up being a trap and Snake's team became suspicious of him. Gary ended up contacting Snake and Teliko when they reached BRC-026 and told them what Pythagoras really was, along with telling them that he wanted the ACUA data in order to become rich and would kill Flemming once he got what he wanted.

Gary and Snake met again inside BRC-026, where he revealed to Snake that he was actually Flemming and called Snake by the name of Hans Davis. He went on to say that Snake, as Hans, created Pythagoras and was a BEAGLE executive. He then told Snake that he would give him the data for Pythagoras, but only if he was truly Hans Davis and no longer Solid Snake. Teliko then showed up and shot the Pythagoras data out of his hands and Flemming escaped to FAR.
He showed up again to capture Leone outside of FAR while Snake and Teliko shut down the powerhouse as a part of their plan to enter FAR.
After battling Snake and Teliko using Metal Gear KODOQUE, Teliko managed to shoot and kill him, thwarting his plans.
