The Eye of Horus (also known as the Eye of Ra) is an ancient entity that takes on the appearance of a green eye. It came from Egypt and has desires of enslaving the entire world.  Those it enslaves become hawk-headed creatures who do it’s bidding.  The Eye of Horus is capable of projecting powerful, destructive energy blasts.  When Dan Garrett (the original Blue Beetle) encountered the Eye, he was only able to defeat it by revealing it’s true name, composed entirely of vowels. Later, the Eye was uncovered by Helen Rock, a reincarnation of Hawkman foe Hath-Set, and used to combat Infinity, Inc.
