Stargate: 10 Best Aliens In One Episode Only
2. Ohnes
This race of aliens are one of the longer-lived ones that SG-1 has encountered. They occupy the world of Oannes, one of three moons around a Gas Giant in the Milky Way Galaxy. They are no friends of the Goa'uld.
They were discovered and many were captured by the Goa'uld Belus, who took many thousands of them away from their world. However, they quickly overpowered the Jaffa on the ship, only to perish as Belus fled and set the self-destruct.
Back on the moon, they also overpowered the occupying army. The Ohne that SG-1 encountered, Nem, was living alone. He was nearly 4,000 years old, waiting to hear news of his mate - Omoroca, who had travelled to Earth in a bid to oust Ra - a task which got her killed.
He has powers beyond that of humans, knocking out the team with a blast of light from his hand, not dissimilar to ascended beings.
