Caroline Forbes

Caroline Forbes is a vampire who is one of the main female characters on The Vampire Diaries. She's the daughter of William Forbes II and Sheriff Elizabeth Forbes. She is best friends with Stefan Salvatore, Elena Gilbert and Bonnie Bennett. She is also close friends with Matt Donovan and Niklaus Mikaelson. Prior to her transition into a vampire, she was known for her insecurities, which caused her to be excessively competitive, mainly with Elena. 

In the Season One finale, Caroline is severely injured in a car wreck and suffers from internal bleeding. Because her situation was looking pretty bleak, Bonnie and Elena agreed that Damon Salvatore should heal Caroline by feeding her his blood. After Caroline's health improved, she was smothered to death in the hospital by Katherine Pierce, who aware that Damon had healed Caroline, knowingly turned her into a vampire. Katherine planned to use Caroline to her own advantage by manipulating her, and eventually giving her to Klaus to kill in a ritual sacrifice. Damon rescues her and Tyler Lockwood, however, and the deal made by Katherine is forfeited.

She attended Mystic Falls High School, where she was the captain of the cheer-leading squad, honor student, head of the dance committees, Mystic Falls beautification committee, head of the recycling program, "Go Green" campaign, Miss Mystic Falls, and one of the most popular girls in the school. 

Caroline's new vampire nature adds difficulty to her relationship with Matt which eventually causes them to break up despite their love for one another. Matt's friend, Tyler, falls for Caroline after she helps him with his first full moon transformation (after she witnessed him triggering the werewolf gene when he accidentally killed someone). After a time, she realizes that she's in love with Tyler too, so they begin an unfortunately ill-fated romantic relationship. One of the original vampires, Klaus Mikaelson, also falls for Caroline, claiming he fancies her because she's beautiful, strong, full of light, "too smart to be seduced by him", and simply enjoys her company. While he is in the woods with Caroline, he asks her to be honest about her feelings for him and that as soon as they are done with that conversation, he promises to walk away and never come back if that is her wish. They ended up having sex. 

Four months after the deaths of Bonnie and Damon, Caroline has dropped out of college and has been trying to find a way to get vampires back into Mystic Falls, as trying to find a way to bring Damon and Bonnie back to the living. 

After the three central characters of The Vampire Diaries, Caroline Forbes is the character that has appeared in the most episodes of all others so far.
