Opticoid

Opticoid (a play on "optical") is a species from the planet Sightra (a play on sight).

Appearances
Opticoids are tan-colored reptilian creatures with at least 17 eyes scattered across their muscular upper body. Their face consists of only a mouth and two pink, bat-like ears that dominate most of their head.

Abilities
Being reptilian, Opticoids can scale walls with relative ease. They also have 360 degree vision. Their most well-known ability is firing energy blasts from their eyes. By joining multiple eyes together, they can fire alternate types of blasts, such as a freeze ray. Their most powerful ability is signaled by all the eyes but the one on their chest vanishing. Their chest eye then gouges out and fires a powerful energy blast.

Also, their bat-like ears can detect would-be attackers and using their enhanced strength to throw enemies with ease. Their vision is similar to Earth's insects and seeing in green, their pupils is also similar to certain Earth's reptiles and felines.

Omnitrix Transformation
The Omnitrix's Opticoid representative is named Eye Guy, who first appeared in the original series episode "Ben 10 vs. the Negative 10: Part 2". It is implied that he was originally unlocked-off screen prior to "Ben 10 vs. the Negative 10: Part 1". Eye Guy solely appears in the original series and Omniverse.

The Ben Tennyson of Dimension 23 has an equivalent of Eye Guy, who first appeared in the Omniverse episode "And Then There Was Ben".
