.Eye Guy is an Opticoid from the planet Sightra. Eye Guy was introduced in the first alternate opening of Secret of the Omnitrix, where Ben is scrolling through the aliens. How Eye Guy was obtained was addressed in Ben 10 vs. the Negative 10 (Part 2) when Ben tampers with the Omnitrix and figures out a secret combination
Eye Guy's debut in the original series Eye Guy's upper-body is covered with eyes, hence his name, although he ironically has no eyes in his head, which consists of a mouth and a very large pairs of bat-like ears for his head.
From his eyes, Eye Guy can fire numerous green energy beams. The eyes can be merged to create different effects, such as three on his shoulder which can form a freezing beam. By merging every eye into the large eye in his chest, he can fire his strongest energy blast. When he does, his eye almost detaches from his body. It is unknown how this will work in Ultimate Alien because he does not seem to have his chest eye. He also can climb walls.
Eye Guy now looks different from the original series.
The eyes on his body are rearranged, the Ultimatrix symbol has moved from his belt to his chest, the eye on his chest is seemingly gone (for an obvious reason)
