Damon Salvatore

Damon Salvatore is Stefan Salvatore's older brother. It is implied that Stefan and Damon have been alive for more than 145 years, and that there was a love triangle between Damon, Stefan, and Katherine. Katherine was in love with both of them and before she left town (and faked her death) she turned them (bit them before they died), but she still couldn't decide who she wanted to be with. But later (when she comes back) we find out that she always loved Stefan. Damon is cynical and likes to antagonize his brother. It's also stated that he and his brother haven't seen each other in 15 years and Damon saying somewhere along the lines "Nice haircut. The 90's grunge wasn't looking good for you." When Damon is back everything gets complicated. Stefan finds new love - Elena, who looks exactly like Katherine. That's why when Damon sees Elena for the first time, he falls in love with her too. Elena loves Stefan, but cares about Damon too. Further in the series Elena will care more about Damon after she discovers his affection for her. So, is our love triangle back after 145 years?

Damon Salvatore is a deadly (but sexy!) piece of work. A blood-sucking playboy, he’s the rebel to his brother Stefan’s saint. Witty, charming, and oh-so-fine, the elder Salvatore brother is a regular people person. Erm, except for the fact he’s got this nasty habit of feeding on them... 

Damon loved his vamp maker Katherine with a fierce devotion and he has spent the last century trying to find her. It was this search that brought him back to Mystic Falls, where he met his little brother’s girlfriend, Elena — who happens to be Katherine’s doppelganger. 

Though he hides his soft side under a layer of snark and a few swills of bourbon, Damon definitely fell for Elena. Hard. But he reacts to her rejection with violence or by acting out. Luckily for Damon, not everyone he kills stays dead. Elena’s little brother, Jeremy, would’ve been a goner if he hadn’t been wearing his magic ring when Damon snapped his neck. 

Damon’s main objectives are keeping Elena safe, no matter the cost, and looking out for Stefan — except when he’s kissing Elena. Despite the moments she and Damon have shared, Elena chose Stefan, once again devastating the elder Salvatore.
