Opticoid

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

Opticoids are tan-colored reptilian creatures. They have at least 17 eyes (none of which are on the face, ironically) scattered across their muscular upper body. Their face consists of only a mouth and 2 pink, bat-like ears that dominate most of their head. Their legs are thin and slightly bulky, and they have 4 fingers and 3 toes.

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 2 or more eyes together, they can fire alternate types of blasts (how this is possible is unknown, but Eye Guy has only appeared twice in the series so he doesn't have enough airtime to explain his back-story), such as a freeze ray by merging 3. 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.
