Drago Pettrovich Madnar

Dr. Drago Petrovich Madnar was a robotics engineer responsible for the creation of the Metal Gear TX-55 prototype and for placing Raiden in the cyborg outfit he wears after the Big Shell Incident.

In 1995, he was captured on his way to the United States and was forced to make war machines for Big Boss in Outer Heaven while his daughter was also held hostage. Petrovich informed Solid Snake of Metal Gear's weakness after he rescued his daughter,Elen.

Four years later, Madnar met with Snake in Zanzibar Land, and appeared to have been taken prisoner along with Dr. Kio Marv. In truth, Dr. Petrovich was in Zanzibar Land voluntarily, overseeing the development of the new Metal Gear D, partly out of revenge for being rejected by the American scientific community and his subsequent institution into an asylum.

Snake, believing Petrovich to be a prisoner in Zanzibar Land, rescued the engineer, who informed him that Big Boss was in command of operations in the area. He orchestrated Dr. Marv's kidnapping, and eventual death. Snake learned the truth from agent Holly White, and confronted Petrovich. The doctor attacked Snake, but was easily defeated and killed by him.

An individual identified as "Dr. Madnar" was the underground cybernetic specialist who outfitted Raiden with a Cyborg Ninja exoskeleton between the events of the Big Shell and the PMC Uprising. It is unknown whether this is Drago Pettrovich (which would mean he survived the events of Zanzibar Land), a relative or someone else.

Trivia

 * In the original MSX2 version of Metal Gear 2, Petrovich's in-game appearance resembles that of Albert Einstein. The 2004 mobile phone re-release, and the updated PlayStation 2 version, reveal Petrovich's full name as Drago Petrovich Madnar, as one of a number of modifications to the game.
 * Dr. Pettrovich Madnar (or Petrovich Modnar, as his name is spelled in the English version) appears in Snatcher as the father of Elijah Madnar, the mastermind behind the Snatcher menace and the creator of Randam Hajile.
