||Rose, played by Lauren Cohan
Rose is a vampire and a friend of Trevor whom she turned in the past. She was the one who gave Katerina vampire blood that transfigured her into a vampire. She looks as if she is in her 20's but her actual age is somewhere over 500.
It is unknown when Rose was turned into a vampire. In 1492, her companion Trevor sent Katerina Petrova to the cottage where they were staying. Rose was furious when she heard that Katerina had fled from Klaus with the moonstone. She locked Katerina in a room and when she came to tie her up, she gave her some blood to heal because she was bleeding from a wound she had done herself, and if Katerina died, then Rose and Trevor would die with her. However, Katerina hung herself to die with Rose's blood and woke up in transition. When Rose tried to kill her, she failed and Katerina escaped them. Rose and Trevor then knew that they would have to be on the run from Klaus and the rest of The Originals until they die.
Rose possesses the powers and abilities of a vampire but some of the standard weakness of a vampire maybe lessened with Rose due to her significant age of perhaps 600 years or more. She is certainly stronger and more powerful than Katherine and depending on her actual age may have been as powerful as Pearl. Damon Salvatore would not be anymore of a match to Rose in a physical fight than he was in his fights with Anna, Pearl, or Katherine. This is shown in Katerina when she easily overpowers him, when he threatens her. Like Katherine she maybe resistant against supernatural inflictions of pain just like Katherine was against Bonnie's attempt to inflict pain by giving her repeated brain aneurysms. Rose does not have a Lapis Lazuli ring, is weak in the sun and probably also be weak with vervain.
