La Gour's secret was finally publicly divulged by his jealous and ambitious bastard cousin, Zu Zambajil. He was branded a traitor, stripped of his title, separated from his pregnant wife and then imprisoned. Lozaria later dies during childbirth while the helpless La Gour could only weep in mourning behind bars. With the aid of the rebels he was able to escape from prison. La Gour then led a rebellion against the empire, but his ragtag troops of former slaves were simply no match against the superior might of the Boazanian military. Even though La Gour was adamant to fight alongside the rebels until the bitter end, his desperate comrades urged the former to live on; they sacrificed themselves in order for La Gour to board their last remaining space saucer which the latter then used to reach planet Earth. Wounded and unconscious in a foreign world, La Gour was found near his ship's wreckage by a local woman, a scientist named Mitsuyo Goh, whom he later marries. Fearing Zu Zambajil's inter-planetary conquest ambitions, La Gour (who now goes by the name Professor Kentaro Goh) collaborated with his wife, as well as premier Earth scientist Professor Hamaguchi and Earth International Defense Force commander General Oka to design and construct Voltes V, his greatest creation and the ultimate defense against a potential Boazanian invasion. After the birth of their third and youngest son, Hiyoshi, Professor Kentaro Goh tearfully left his newfound world and family; he returned to Boazania as a diplomat in a peaceful effort to abate the cruelty and tyranny of the now current reigning emperor, Zu Zambajil. Instead of listening to Professor Goh's appeal of non-violence towards other planets, the ruthless monarch offered his long lost cousin the lofty designation of being lead designer to Boazania's inter-planetary war machine. Disgusted by how vile and despotic Zu Zambajil had become, Professor Goh vehemently refused the Boazanian emperor's proposition and was therefore incarcerated. Much of the series' plot revolve around La Gour's sons discovering the reasons behind their father's disappearance as well as his secret origins, both of which are related to the Boazanian Earth invasion. Eventually, the Voltes Team made their way to planet Boazan and the Goh brothers were finally able to reconnect with their father. La Gour and the Boazanian rebels collaborated with the Voltes Team in order to ultimately terminate Zu Zambajil's despotic rule. The series' finale revealed
