Zeon Zum Deikun

Zeon Zum Deikun is a fictional philosopher and politician in the Gundam stories, in which he developed Contolism, which was both about Ere-ism (that Earth is sacred and mankind must leave it and live in space) and Side-ism (all space colonies should be independent from the Earth Federation). He was also the creator of theNewtype theory, which believed that humans, who have needed to communicate with each other throughout time, would eventually develop a sixth sense to mentally communicate.

Since the people of the colonies were considered to be lower echelon of society compared to those living on Earth, Zeon's teachings were welcomed by the colonies, especially Side 3 (L2), which eventually appointed him leader of the Side. After the Colony Republic announced its independence, the Federation responded with the Bardot Policy, which halted all resources to Side 3. Deikun responded by creating a Colony Republican Guard in case the Federation decided to invade the colony to stop their push for independence. Soon after this, Zeon suddenly died. His friend and closest advisor, Degwin Sodo Zabi, claimed that Zeon named him successor on his deathbed. Many believed that Degwin had Zeon assassinated, but no concrete proof ever surfaced. Degwin changed the Republic of Zeon into the Principality of Zeon, appointing himself as Sovereign and placing his four children in high-ranking roles. Degwin kept the name of Zeon for Side 3 to honor his friend, but mainly to help draw suspicion of Zeon's death away from himself. All of Zeon's most loyal followers were eventually killed in a purge ordered by Degwin.

Zeon had two children: a son Casval Rem Deikun and daughter Artesia Som Deikun. Both were targeted by Degwin's purge but survived and went into hiding thanks to Zeon's family friend, Jimba Ral.
