|“||Shame about Mary, she used to be a blast. Don’t quite know what happened. I fear all the time she spent with my family might have ruined her. She was a bit of an Original groupie.||”|
Mary Porter was a vampire who turned Rose into a vampire back in the 15th century. In the present time, she lived in a house which Damon referred to as a "vampire hoarder" in Kansas. She belongs to the same bloodline as Katherine, Stefan, Damon, Abby, Caroline and Elena. She was turned by Klaus and killed by Kol in his attempt to prevent Damon from finding out who turned her in order to find out who his bloodline originated from. Kol called her an "Original-Groupie", spending intimate time with Elijah, Klaus, Kol, and even Rebekah. She was found dead, hanging on the wall inside of her house with a baseball bat through her heart.
Although Mary was destroyed before interacting with the main characters, it is mentioned part of her nature, as well as her lifestyle. Damon refers to her as super creepy but not ugly. This can be asserted in her lifestyle, as she used to live in remote places, dark, damaged, and one can assume that attracted men for fun (Damon referencing that they had intercourse). One of the qualities of Mary is that she hid or live a life in the shadows, this could be due to lack of walking freely in the day. Kol hints that time spent with his family may have driven her to her current state.
We know almost nothing about Mary Porter's appearance except her hair (ginger-blonde, medium length, wavy) because before we could see her, Kol killed her to prevent Elena and Damon from finding out who turned her - so we see her as a corpse with closed eyes and ashened-greyish skin.
