Eyeguy is a major character in Omni-World.
Not much known about Eyeguy's personality, but it seems he is a little stupid.
Ditto is Eyeguy's best friend. Ditto helped him write a song in The Spiked Symbols.
He, along with other roommates Ultimate Cannonbolt and Wildvine, form the gang who often get into silly adventures.
He doesn't know Brainstorm well, because Ditto always does the talking for him to Brainstorm, but it is confirmed that they will meet in an upcoming episode.
Unnamed female Eyeguy counterpart
Like every alien, he has a female counterpart, but it isn't show if Eyeguy has a relationship with his counterpart, mainly because his counterpart hasn't appeared yet and no plans are confirmed.
