|The following is based on the spin off novel by Keith R. A. DeCandido and some details might contradict canon.|
Javier Vega was a GDI Major during the Second Tiberium War.
He served with Michael McNeil. Although he was the brother of prominent Nod General and South American Eye Candy dealer Cesar Vega, the GDI has since overlooked that fact and granted him much fame and recognition due to his often-heroic service. His son Ricardo Vega followed in his footsteps during the Third Tiberium War.
Javier Vega is mentioned in the Tiberium Wars novel.
