Eyezor

Eyezor is a Hardmode enemy that spawns only during a Solar Eclipse, during which they are spawned as uncommon enemies. They travel faster than normal Zombies, like other Solar Eclipse enemies. They spawn relatively rarely, but shoot powerful lasers from their eye and are immune to knockback, making them a formidable enemy during the Solar Eclipse.

Trivia
Eyezor may be a pun on the term "eyesore", implying he is unpleasant to look at.

It is also possible that it is a portmanteau of "eye" and the misspelt word "laser" (lazor).
