Luther

Luther was the leader of a small group of vampires and the female vampire Kate is his mate. He was shot with The Colt by John Winchester.

Personality
Luther was the leader of his group of vampires. Because head vampires are usually the eldest of the group, this may also apply to him, and he may or may not have turned all the members of his group into vampires as well, similar to way that Dixon and Boris built their nests. Like many nest leaders, Luther believed in enjoying eternal life, but also in keeping a low profile to avoid attracting hunters, as evidenced by the fact that he hadn't taken his own revenge against Daniel Elkins for what was done to his family and the way he became upset with Kate for doing so.

Powers and Abilities
Luther possessed all the powers and attributes of a vampire, however as he was older than most, he was stronger than most vampires.
 * Superhuman Strength - Knocked John Winchest through the air with a flick of his wirst.
 * Super senses - Stronger than the younger vampires, was able to track Kate sent, while the others couldn't.
 * Enhanced Speed
 * Enhanced Agility
 * Invunrability
 * Immortality

Early Life
Apparently born in the 1800s, as The Colt was made around the time when Luther was born. He has history with hunter Daniel Elkins who presumably killed his family.

Season 1
Luther returned to the nest after the others made an acquisition of a traveling couple. Once he eyed them over and found the woman to be "interesting", he gave the order that she was to live and the man was to be locked up with other gathered prey. After a second thought, he decided the group could "treat themselves" to the man and laughed as his nest-mates devoured the man as the woman watched on helplessly, then started making out with Kate.

Later, as the rest of the nest were sleeping, he and Kate graduated from making out in front of the female hostage to stripping in front of the female hostage. When stripping began to include groping, he noticed the woman's terrified, fleeting glances and then watched as he had Kate feed the woman her blood, turning her into a vampire. In the day as the vampires slept, the Winchesters snuck into the nest to both free the hostages and to retrieve the colt with as little collateral damage as possible. When the newly turned vampire (mistaken as still being human) alerted the nest to their intruders, Luther awoke and managed to prevent John from getting the colt. The hunters fled, with the vampires unable to pursue due to it still being daylight.

That night, he sent Kate and another vampire after the Winchesters, only for Kate to be captured and the other vampire killed. When John lured him away from the nest by using Kate as bait (so Dean and Sam could go in for the hostages again), Luther agreed to exchange the colt for his mate. When Kate broke free of her bonds prematurely, she and Luther got the upper hand on John by knocking him unconscious. As they were about to kill him, Dean and Sam arrived and a small scuffle ensued, resulting in a stalemate of Luther threatening to snap Sam's neck if Dean didn't disarm himself of his machete. As he begins to talk about what monsters hunters were, a re-awakened John surprised the vampire and shot him the head with the colt, killing him. ("Dead Man's Blood")

Trivia

 * He is the first Supernatural being to be killed by The Colt in the entire series (but not chronologically).
 * Luther's knowledge of the colt indicates that he is more intimate with hunters and hunting in general than many other creatures on the show. This is rampant speculation, but it may be possible that Luther had been a hunter before becoming a vampire, and perhaps used the gun himself at one point. However, this is unlikely.
 * He has the Japanese Katakana ネヨラヨテ (Neyorayote) tattoed on his right arm. However, this is not a Japanese word and it is unclear what it means.
