Solid Snake
Dr. is a Czechoslovak biotechnologist. In the backstory of "Solid Snake", Marv successfully creates a new algae species called OILIX that could produce petroleum-grade hydrocarbons with little expense and effort. Marv presented the algae to the World Energy Conference in Prague, and was on his way to a demonstration in the United States when he was kidnapped by soldiers from Zanzibar Land. Solid Snake is brought out of retirement by FOXHOUND's new commander, Roy Campbell, and is sent to Zanzibar Land to rescue Dr. Marv. However, he dies of torture in his cell and left behind the OILIX plans for Snake to find.
