Scar

Scar was the name given to a one eyed Wraith that roamed on the planet Halcyon.

He was present during his kinds war against the Lantean's thousands of years ago where his Hive-ship was damaged in the battle and forced to crash on a Human world. Scar and his comrades would go into hibernation; sleeping for centuries until a rescue ship uncovered them but none came.

One kingdom of Halcyonites discovered the sleeping ship and attempted to use the Wraith within as Hounds; shocktroopers in their wars against one another. This would ensure the kingdoms dominance over the other factions, however, the hibernation systems were deactivating allowing more Wraith to awaken one of which was Scar. He would be wounded by the king of the ruling Haylconite domain which earnt him the name Scar for the deep wound across his eye.

Scar would be deposited in a reserve where wild members of his kind roamed and were hunted by the Humans as sport. This was because of the effects of the Dolmen which dropped the intelligence of the Wraith to animalistic levels. Scar, however, was different and of a higher caste resulting in him retaining enough of his intelligence to become a threat and led a group of his kind against the Halyconites. When Scar encountered the flagship team of the Atlantis Expedition; he saw a way for freeing his kind and blackmailed Colonel John Sheppard by threatening Teyla's life.

Using a Lantean Puddle Jumper, Scar would destroy the Dolmen and free his brethren which began to wreak havoc of Halcyonite society.
