An Eastern Bloc leader was rumored to have used Big Boss as a guinea pig for Dr. Drago Pettrovich Madnar's Snatcher project. Eager to get his hands on the renowned mercenary leader, he supposedly provided Big Boss with cybernetic body parts to compensate for the injuries he received during the Outer Heaven Uprising in 1995. These rumors were relayed to Solid Snake during the Zanzibar Land Disturbance in 1999 by George Kasler, who referred to the leader as a despot.
Behind the scenes
The Eastern Bloc leader was only mentioned in an optional radio conversation in Metal Gear 2: Solid Snake, regarding Big Boss' survival of Outer Heaven. It is unclear if he actually existed. Although the Metal Gear Solid 4 Database does mention the project in question, it was revealed to have never happened in Metal Gear Solid V: The Phantom Pain.
