Connor Jordan was a vampire hunter, who first appeared in the second episode of the fourth season of The Vampire Diaries. He was highly versed in the "deadly arts," and was also known as a "highly trained killing machine." He showed up in Mystic Falls after the newly-reformed Town Council was blown up in a mysterious explosion, and he started to target the town's vampires. He was a dangerous and unpredictable hunter who was capable of holding his own against vampires, despite not having their level of supernatural strength. He was ultimately killed by Elena Gilbert after he ignored her warning to stay away from her brother, and she subsequently suffered upsetting hallucinations of him afterward due to the effects of the Hunter's Curse, during which he tormented her into trying to kill herself.
Connor was a member of Brotherhood of the Five, a group of supernatural vampire hunters that was established in the early 12th century. Connor, despite being a member of the order, knew nothing about them or their purpose, nor did he know any of the other members except for Jeremy Gilbert, who he identified as a potential member when he was able to see his Hunter's Mark.
