Genome Soldier is a generic enemy soldier type in Metal Gear Solid, rather than a named individual character. They are enhanced military personnel deployed by FOXHOUND and other forces, often serving as standard infantry opponents throughout the game. In the series, Genome Soldiers represent the use of genetic engineering and advanced training to create highly capable troops. They function as the primary rank-and-file antagonists, providing the player with stealth and combat challenges while reinforcing the game's themes of militarization, cloning, and biological enhancement.
