Eye Guy

Eye Guy is the Omnitrix's DNA sample of an Opticoid from the planet Sightra.

Appearance
Eye Guy's upper-body is covered with green eyes and black pupils, although he ironically has no eyes on his face, which consists of a mouth and a very large pair of bat-like ears. He has dark yellow skin with lighter yellow skin on his chest and feet.

Eye Guy wears black pants with white circles on them with a white belt. He wears the Omnitrix symbol on his belt in the original series and he wears the Ultimatrix symbol on his chest in Ultimate Alien. Because of this, the eye on his chest is gone in Ultimate Alien.

In Omniverse, 16 year old Eye Guy looks almost the same as the original series, but now the white stripes on his pants have been replaced with green circles and his belt is now green with white stripes on the left and right of it. He wears green cuffs and his eye placement is slightly different, and bigger. He has also gained eyes on his hands. He has a green belt where the Omnitrix symbol is located.

11 year old Eye Guy looks the same as the original series but now has white cuffs, eyes on his hands and the Omnitrix symbol on his belt is now green.

In Evil's Encore, it is shown that Eye Guy's chest eye is hidden unless activated.

Powers and Abilities
From his many eyes, Eye Guy can launch energy beams. His eyes can move throughout his body and merge together to create different types of beams, such as merging three on his shoulder to fire a freeze ray. Eye Guy can shoot fire beams as well.

By closing all of his other eyes, or by merging all of his other eyes into that one area, a larger eye will open on his chest, and from it he can launch his most powerful blast, and while doing so his eye almost detaches from his body.

Eye Guy's insect-like vision views every angle, making it extremely difficult to sneak up on him, as displayed in Ben 10 vs. the Negative 10: Part 2, Rad, and Something Zombozo This Way Comes.

Eye Guy has enhanced hearing.

Weaknesses
If an irritant gets in Eye Guy's eyes, he will be unable to see clearly, in addition to his eyes burning, leaving him temporarily blind. It is has been shown in Rad that his eyes can be blinded by Gracklflint venom.

As seen in The Ultimate Heist, Eye Guy is sensitive to high-pitched noises, in this case Negative Ultimate Echo Echo's sonic disks. This is in part of him having large ears.

His insect-like vision becomes a weakness when he gets distracted or faces something or someone that he has a deep fear of like Zombozo.

If he gets shot on his chest eye, he will turn completely grey, weakened.

Trivia

 * In Omniverse, Eye Guy has a tendency to make puns involving the word "Eye".
 * Eye Guy is an allusion to Eye Guy, a Mighty Morphin Power Rangers villain; like Eye Guy, he has many eyes. As with the allusion to the Power Rangers villain, the two characters have basis from a character in Greek mythology known as Argus Panoptes who is often described as having hundreds of eyes.
 * Eye Guy is the first ever alien to have been unlocked offscreen.
 * Eye Guy's name in the credits of Ben 10 vs. the Negative 10: Part 2 was misspelled Eye Gye.
 * Ironically, Eye Guy has an eye almost everywhere on his body except his face.
 * The way Eye Guy has an eye on each hand is similar to Pale Man, a villain from the film Pan's Labyrinth.
 * It's revealed in Rad that his eye vision is all green.
