Javier Hidalgo was the leader of the drug cartel, the "Sacred Snakes". He was the main target in the "Operation: Javier" segment of Resident Evil: The Darkside Chronicles, as he has taken de-facto control over a large area of jungle. He rules the entire area absolutely. The small government is unable to do anything about Javier’s control of the drug trade, so Jack Krauser and Leon S. Kennedy have been called in to infiltrate this small South American country and find him.
The drugs that Javier’s organization is producing have been contaminating surrounding countries, as well as finding their way into America. Javier was amassing a fortune in drug money, building up his own private army, and fortifying his operations. He was a wanted criminal in many countries, and is an uncommonly cruel man.
This ability to slip through the fingers of justice and gather other criminals is not something an ordinary person could accomplish. Javier has achieved his goals through the use of violence and strict control of the region. He rewards those who submit to him, and brutally punishes anyone who stands in his way, making harsh examples of anyone who opposes him. He rules his dominion through fear.
