Zanon

Zanon is an mastermind and the main antagonist of the 1980 Daiei film Gamera: Super Monster.

Gamera: Super Monster
Zanon appears from deep space piloting a massive spacecraft towards Earth. Earth's resident heroines, the Spacewomen, try to fight against Zanon and his forces, but are easily held back by Zanon and his crew. He then reveals his plans to enslave Earth, and in doing so revives the Gyaos, Zigra, Viras, Jiger, Guiron and Barugon, setting them upon the Japanese islands. The Spacewomen escape, and find a boy with a connection to Gamera, who manages to wake the sleeping turtle. Gamera heads off to fight the other monsters while Zanon commands his pawns from above. After Gamera defeats Zigra, he briefly utilises a mind-control device on Gamera, making him wreak havoc on a dam, but Gamera eventually breaks free. After Gamera defeats all of Zanon's monsters, he personally fights back, using his spacecraft, but dies after Gamera sacrifices himself to destroy the ship.

Name
Zanon's name appears to be derived from the Noble gas element Xenon, which in turn is derived from the Greek term Xenos, meaning 'foreigner'.

Trivia

 * Zanon's spaceship bears a suspicious resemblance to an Imperial Star Destroyer from the Star Wars series of films, and this was most likely a deliberate attempt by Daiei to attract attention and capitalise on the success of the films.
