Omega The Unknown #1 (1976)
Protaris, Regreb System, Milky Way Galaxy
The Protar are an advanced race, and although they have reached an evolutionary standstill, they have mastered space travel on vast scales, presumed space and planet colonization, advanced energy based weaponry, warp drive star-ships, and advanced genetic technology enabling them to create artificial biological life-forms.
They are bilaterally symmetric, with two legs and arms terminating with feet and hands respectively. Protar's hands have five independently moving digits, each with opposable thumbs. Protar's have a glowing face-plate instead of two eyes, a nose and a mouth.
When model X-3Z was thought to be a success, he was offered a tremendous honor among his adopted Sreneskian people. X-3Z was to be endowed with the ability to tap into the very life force of their world. The Protar knew the power was too great for any being to control, so they attempted to halt the process. They were too late, and their intentions were misunderstood by X-3Z. Thinking the Protar were an invading force, X-3Z utilized his new gift and accidentally killed the Sreneskian race. The Protar sensed X-3Z's power had been passed onto their final creation, James-Michael Starling, and it was decided to destroy them both. X-3Z resisted and traveled to Earth to protect the only individual he now felt a connection with.The Protar pursued but were thwarted at every turn by X-3Z – now under the moniker of Omega – and James-Michael. One Protar had even been captured and reprogrammed by the maniacal Electro. Eventually, Omega was killed by police in another misinterpreted event, and their pursuit of James-Michael brought them into conflict with the Defenders. It wasn't until Moondragon discovered the Protar's origins that she realized what the real danger was. Upon learning his true nature, James-Michael wanted to destroy the Earth but was unwilling to sacrifice the only friend he had; so he turned his incredible power onto himself. With his death, the Protar completed their mission, but they were left without replacements to take over where they would leave off.
