Alien Species

Opticoids, alternatively known as Sclerans,[1] are a species from the planet Sightra.[2]



Opticoids are reptilian creatures with two-shaded skin and 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. An Opticoid's skeleton is made entirely out of stiff cartilage rather than bone.[2]

Opticoids can grow little tentacle-like whiskers, similar to the Galvan.[3]

Female Opticoids have slimmer builds, more voluptuous figures, and feminine eyelashes on their ears.

Although they traditionally have tan skin, Opticoids can come in other colors. For example, Opticoids from Dimension 23 have grey skin.

Powers and abilities

An Opticoid's most prominent ability is firing energy beams from any of the eyes on their torsos. These beams come in different colors that correlate with that of their eyes including green, blue, red, pink, and yellow.

An Opticoid's eyes can move throughout their bodies and merge with each other to create different types of beams, including freeze rays, fire blasts, electric beams, and sticky goop.[2]

By either closing all of their other eyes or merging their eyes into a single area, a larger eye will open on an Opticoid's chest and launch a powerful optic blast. While doing so, they can stretch out and move their firing eye towards targets.

An Opticoid's insect-like eyesight gives them 360-degree vision, making it extremely difficult to sneak up on them.

Opticoids possess enhanced hearing due to their bat-like ears, allowing them detect would-be attackers.

Opticoids possess enhanced strength, enough to lift a Tetramand and pin an Osmosian with ease.


If an irritant gets in their eyes, Opticoids will be unable to see clearly, in addition to their eyes burning. As they have eyes over the majority of their bodies, they become vulnerable to being exposed and hurt by irritants.

Despite their enhanced hearing, Opticoids are sensitive to high-pitched noises, such as those produced by an Evolved Sonorosian.

Culture and society

Opticoids have a tendency to make puns involving the word "eye" or organs related to the eye.



  • 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". Counting his DNA Pod, Eye Guy has appeared in almost every series except Alien Force and Ultimate Alien.
    • Eye Guy has also been used by the Omniverse (Video Game) version of Ben,the Omnitrix Unleashed version of Ben, the Wrath of Psychobos version of Ben and the Omniverse 2 version of Ben.
    • The Ben Tennyson of Dimension 23 has an equivalent of Eye Guy, who first appeared in the Omniverse episode "And Then There Was Ben".
  • The name Opticoid is a play on "optical", meaning related to eyes. The alternate name Scleran is a play on "sclera", the white area of the eyes.
  • Before making their debut in the reboot series, the presence of Opticoids was teased by concept artwork of Omnitrix DNA pods before it was eventually confirmed that the Omnitrix in that series contains Opticoid DNA.[4] Therefore, Eye Guy is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
    • This has been supported by the appearance of the Opticoid Prisoner in the film Ben 10 Versus the Universe.
