He's nice, caring, reliable, stable, and extremely loyal to those that he loves.
Elena Gilbert is a fictional character and protagonist from the novel series The Vampire Diaries. In the television series adaptation, set in the fictional town of Mystic Falls, she is portrayed by Nina Dobrev.
Caroline is actually Stronger, but Elena was trained to kill vampires as a human. They both fought when Elena had her humanity off and she almost killed Caroline.
Paul Wesley and Nina Dobrev met through their roles as Stefan and Elena on "The Vampire Diaries." Dobrev said that they actually "despised each other" at the start of the series. The actress said that nowadays, Wesley is the "TVD" costar she's closest to.
Katherine was a selfish and self-centered manipulator who fought to become a vampire and only truly cared about herself, whereas Elena was caring and compassionate and longed to be human even after her transition to vampirism. Both doppelgangers were great characters who garnered a dedicated and passionate fanbase.
Elena Gilbert has a strong and confident personality. She's not afraid to speak her mind and stand up for what she believes in. She's also fiercely loyal to her friends and family. On the other hand, Bella Swan is often portrayed as a weak and indecisive character who struggles to make decisions for herself.
Stefan loved Elena more than anyone else and was entirely devoted to her. They both wanted to pursue a human life, whereas Damon enjoyed being a vampire. Elena reunited with Damon in the series finale, but she would potentially have been a lot happier if she had chosen to be with Stefan instead.
Despite Stefan being painted as the "good" brother, one particular Vampire Diaries episode showed why Damon was actually the more selfless brother. Despite Stefan being positioned as being the "good" one, a scene in The Vampire Diaries season 5 proved that Damon was secretly always the better brother.
Elena confesses she still loves Stefan but no longer is in love with him and is in love with Damon. Stefan and Caroline realize that her feelings may have something to do with the fact that she's sired to Damon. Damon struggles to come to terms with this and begins to doubt her feelings for him.
Hybrids. With the powerful combination of vampire and wolf abilities, and even thicker skin than normal vampires (there's really only two ways to dispatch them from the real world), hybrids are amongst the most durable creatures in the TVD Universe.
Elena is considerably weaker as a younger vampire, though she still stands her ground against Katherine. Had Elena remained human, then her epic confrontation with her evil doppelganger would never have come to fruition.
Rosalie is described as being the "most beautiful person in the world", as she is astoundingly gorgeous, even for a vampire.
Bonnie was stronger than Elena and Caroline.
When Katherine first came back to Mystic Falls in 2010, she was jealous of Elena for earning the affections of both Stefan and Damon, as she had also had relationships with both brothers in the past and, while she never truly loved Damon, she was still in love with Stefan.
At the beginning of the series, Elena appears to be a regular human girl, but is then revealed to be a Petrova doppelgänger. In the Season Three finale, she became a vampire despite never wanting to be one. In I'd Leave My Happy Home For You, she takes the Cure to become human again.
Caroline Forbes (Full Name: Caroline Beula Forbes) is a female character and a supporting character of The Vampire Diaries novel series. She is the old childhood friend turned rival-enemy of Elena Gilbert.
Coming in at first place, Stefan is credited with eighty-three kills over the span of the show's eight seasons, most of which were during his ripper periods.
Caroline later confessed to Bonnie that she was jealous of Elena.
