Does anyone know where the idea for the name "Omega Men" originated? I mean, does the name have any special significance or meaning behind it for the characters? I know Omega is the last letter in the Greek alphabet, though since the Omega Men are all space aliens from the Vega System I dunno if its original earthly meaning has any significance.

2 years later and we now have an answer to this.

@jonny_anonymous: The new series certainly does make that clear with the connection to the Vega System deity Omega & the idea of the group existing to bring an end to the Citadel, AKA the Alpha Empire, though I still wonder what the original meaning behind it was when Marv Wolfman first created the team. Perhaps simply a reference to them being the Vega System's last hope for freedom from the original Citadel?
