Omega Team
The Omega Team was one of two teams formed to fight the Rikti Invasion in a daring plan by Dr. Science. The team consisted of 50 heroes, mainly magicians and/or heroes wielding artifacts, led by Hero 1. While Statesman's Alpha Team launched a frontal assault on the Rikti invaders, the Omega Team waited while invisible until the portal to the Rikti homeworld was clear. Once it was, the team ran through to close the portal to Earth once and for all from the other side. After a tremendous explosion, the portal was shut down, but at the cost of the presumed total loss of all but one member of the Omega Team.
The only survivor of the Omega Team was the hero Ajax, who was caught in a Rikti stasis ray before he was able to run through the portal.
