OMEGA is the oldest member of The Void. He gives the tests that others have to pass before t hey can join The Void. After the night of February 5th, though, OMEGA now does what Captain did, and seems to have some new powers. He calls Him whenever the Chatzy site is broken into. He seems to know where you are on the internet, for if you break into a site, he'll show up.
The name omega is deprived from the Greek Alphabet, with omega being the last letter.
