His transformation style from Leito Igaguri was consciously modeled after Ultraseven's use of Ultra Eye.

ULTRAMAN ZERO MOVIE FULL SERIES
Series main writer Otsuichi was dubious of Zero's involvement as part of the cast of Ultraman Geed, believing that he is a poor character but director Sakamoto managed to expand him by forming a senior-junior pair with the titular Ultra. In Ultraman Saga, a comical plot was suggested to the character as a new element and Zero's 5 meter-transformation is based on proposal made by VFX producer as part of an Ultra Warrior's relationship with humanity. His youthful and hot-blooded outlook is based on Joe Yabuki from Ashita no Joe while his fighting skills revolves around the combination of Ultraseven and Leo. The setting of Zero as Leo's pupil was made under suggestion of director Koichi Sakamoto incorporating elements of his favorite Kung fu films. Ultraman Zero's title as "the son of Seven" laid a huge impact on the audience. Movie producer Junya Okabe stated that Zero's involvement in Mega Monster Battle: Ultra Galaxy was to invoke the elements of a parent-child relationship.
Introduced as an energetic, boastful, and stubborn warrior, Zero was sent into banishment by Ultraseven after his failed attempt to steal the Plasma Spark. He first appeared in Mega Monster Battle: Ultra Galaxy before starring in his own film Ultraman Zero: The Revenge of Belial and its 2012 sequel Ultraman Saga. Ultraman Zero ( ウルトラマンゼロ, Urutoraman Zero) is a fictional character from the Ultra Series.
