Ultra Eye

The Ultra Eye (ウルトラ・アイ, Urutora Ai) is Dan Moroboshi's transformation item. With it, he can transform into his true self, Ultraseven. His famous quote before he transformed was "DWUAH". Other users of the Ultra Eye are Run, Taiga Nozomu (Ultraman Zero's human hosts) and Jin (Ultraseven X).

Unlike any other transformation items, this item transforms Dan and his hosts into Ultraseven without any rise action. Instead the transformation scene is Dan, or a human host, transforming into Seven from the head down. Jin, on the other hand, transformed in real time in a burst of red light. Ultraman Zero's transformation had a more typical rise.

Ultraseven's
The original Ultra Eye was simple. Upon use there was a transformation scene where the glasses would disappear and morph Dan into his Ultra form from head to toe. Often times Seven would be human size and would take on giant size afterwards. It is unknown why he uses it when he has shown himself able to transform without it as common for Ultramen who change there appearance to humans instead of merging with them. Later on, during the time of Ultraman Leo's stay on Earth, Seven was gravely injured. As a result, the Ultra Eye was damaged, leaving him stranded in human form for some reason until Ultraman Jack took it back to the Land of Light for repairs.

Ultraseven X's
Technically, Ultraseven X's Ultra Eye was the same as the original. But like Ultraseven himself, the Ultra Eye also received an update, looking more sleek and streamlined. Upon use, the Ultra Eye turned into a light that covered Jin and morphed him into Ultra form, with a bright flash, but in real time.

Ultraman Zero's
Zero's Ultra Eye was more streamlined, with white and blue colors and resembling a mask more than his father's. His version of the device known as the Ultra Zero Eye, to differentiate it from his father's. His could also be folded in half and be used as a blaster. Upon use, the trasformation scene shows his host floating in a prismatic space with the Ultra Eye on, while light gathered around them, morphing him into Zero. Another characteristic that seperates Zero's from his father's is that when they are not in use they are store in the Ultra Brace around his or his human hosts/forms left wrist until it is summoned
