- "Fate made us train together, and fate will send you to your doom!"
Vargas is the son of the martial arts master Duncan Harcourt. Thus, he was next in line to be the master of the dojo he trained at, which was located near Mt. Kolts. Vargas had a major rival in Sabin, who was more talented than him. Vargas always thought Sabin would be the next master and attacked and killed Duncan out of rage for what he perceived as a snubbing when Duncan would chose Sabin to be his successor. This is later revealed to be untrue, however, and Duncan is found alive by the player later in the game.
One day Vargas snuck out of the dojo and began climbing Mt. Kolts. Terra, Locke, and Edgar catch up to him and Vargas picks a fight with them. Sabin shows up, confronting Vargas about his apparent murder of Duncan. Vargas reveals his reasons, and Sabin claims that Duncan had chosen Vargas as his successor, not Sabin. Vargas refuses to listen and duels Sabin one-on-one. Sabin defeats Vargas using a Blitz technique, catching Vargas by surprise as he hadn't expected Sabin to know such an attack yet.
After their duel, Vargas is not seen or mentioned again throughout the game, and the ending of the battle and the way Vargas' sprite vanishes from the screen leaves it ambiguous if he fled after being defeated or was slain by Sabin.
