A former pilot for the South Vietnamese Air Force. He encountered Mickey several times during the Vietnam War, and he was known as the "Shark of Tonkin Bay". He frequently argues with Shin, mainly because Shin shot down a friendly fighter whose pilot was blinded. Flying the F-105 Thunderchief, Nguyen enjoys the killing of enemy pilots, and even shoots an enemy pilot as he ejected from an aircraft. Despite his disagreements with Shin, he comes to respect him. He suffers the fate of the pilot he shot down, being shot as he ejected from an aircraft. Nguyen appears in the OVA and manga series but not in the Eclipse comic series.
