Ultra Zero Eye

Ultra Zero Eye (ウルトラゼロアイ) is the transformation item of Ultraman Zero. It is designed after his father's Eye Slugger. When not in use, it is stored within the Ultra Zero Bracelet, now Ultimate Bracelet.

Usage
The Ultra Zero Eye possess two forms, Gun Mode and Zero Eye Mode.

Zero Eye Mode
The Zero Eye Mode (ゼロアイモード) is the Ultra Zero Eye's original form. The transformation steps can be made by either having the host wearing it on their face or having the Ultraman himself controlling the Zero Eye telepathically, therefore creating a forced transformation.

Once they don it, the ribbons of light and the Zero Sluggers appear with Zero's body materializing on the human host's before the Zero Sluggers attach and appeared in the human world. During Taiga's second and final transformation as Zero, he jumps in mid-air and is surrounded by multiple light streams. At that time, Zero's three illusory images merge with him to complete the steps.

Gun Mode
Aside from conventional transformation item, closing the goggle allows their user to utilize Gun Mode (ガンモード), firing laser ammunitions. This was used by Run/"Zero" to save Nao and Emerana from a falling pillar before he loses grip of the Ultra Zero Eye.
