Lorenzo

Lorenzo, better known as Enzo, is a main character, antagonist, and anti-hero in the The Vampire Diaries. He was formerly a major recurring character in the fifth season of the series, before being promoted to main in the sixth season. He is a vampire who was previously Damon Salvatore's cellmate in the 1950's, after being captured by the Augustines. He was first mentioned by Dr. Wes Maxfield, being dubbed as the "Augustine Vampire".

In Season Five during Man on Fire, Enzo and Stefan get into an intense fight with one another. Enzo attempts to set Stefan on fire, but Stefan pushes his hand inside of Enzo, grabbing his heart. Stefan refuses to kill Enzo, but he steps back and Enzo's heart is extracted. Enzo tells Stefan that his revenge will consist of Stefan explaining to Damon how he killed his best friend. Enzo later passes through Bonnie to The Other Side.

While on the Other Side, Enzo realizes that since Markos has emerged into the world of the living, that the dimension is falling apart. He tries his best to figure out how to get out of the Other Side, putting his trust in Bonnie. In Home, Markos is sucked away into Oblivion and Enzo successfully passes through Bonnie, returning to life.

In Season Six, Enzo begins a mission to save Damon and Bonnie from the prison world they are trapped in with the help of Caroline Forbes. He flirts with Caroline and also antagonizes Stefan for abandoning his search for Damon. After Damon's return, Enzo develops a jealousy towards Stefan and vows to make his life miserable. He forced Matt Donovan to assist him in doing so but later changes his mind when he begins to care about protecting Stefan's niece, Sarah Nelson. He later encounters Lily, the woman who turned him into a vampire and also happens to be Damon and Stefan's mother.

Early Life
In 1903 South Hampton, England, he was denied passage on a ship to New York because of his consumption but Lillian Salvatore helped him get aboard the ship so he could see a doctor on the ship who turned out to be a charlatan. Lily gives him her blood so he can be a vampire, he later dies of consumption before the ship docks in Manhattan Harbor. Before he awakens in transition, the Gemini Coven catches up with Lily and her traveling companions, who are Heretics. She and her family had killed everyone aboard except the charlatan doctor, leaving him to Enzo so he could complete his transition. He believes Lily left him and is unaware that she was now in a 1903 Prison world.

Enzo was found by the Whitmore family after he left his post in Eastern Europe during WWII. He was imprisoned by Dr. Whitmore and forced to endure his torture for ten years. In 1950, Enzo was a prisoner of the Augustine Society, He was used as an experiment in the laboratory at Whitmore. James was responsible for the study of his behavior and took notes about him. They began to develop feelings for each other later on. Later, Maggie wanted to help him escape and she asked him to turn her into a vampire. She wanted to escape and be with him forever, but Enzo, in order to protect her, took off her bracelet which had vervain on it, and compelled her to forget about him and leave. He returned her bracelet and she left.

As Damon was imprisoned due to Joseph Salvatore selling him out, Enzo reached out a hand of friendship with the young vampire. They would talk about many things to keep their hope of escape up. Enzo planned to have Damon take his ration of blood for a year so that he would be stronger and assist in the escape. During the annual New Year's Eve Party at Whitmore, Damon broke free of his chains and attacked everyone but, in the process, caused a fire. Enzo was still stuck in a cage laced with vervain and Damon attempted to free his friend to no avail. Realizing that he could not free his friend and fearful that Augustine would take him back, Damon turned off his emotions and abandoned him. Enzo continuously screamed for his friend to free him and was presumed dead.

Personality
Enzo is a charismatic person who had lived quite a fulfilling life prior to his imprisonment by Augustine. Despite his imprisonment, he remained optimistic and hopeful to one day escape and possibly take revenge on Augustine for their torture on him. After it is revealed that he was still alive and imprisoned, Enzo seems to have become mentally unhinged as a result of the five decades of torture, as he slowly hums a song just after he introduces himself to Elena. He also showed immense anger towards Damon for being unable to save him, nevertheless after rekindling their friendship, he refused to abandon him when he turned into an Augustine Vampire. He shows that he is loyal and would never abandon those important to him. He is also shown to have a vengeance streak as seen when he helps Damon with the Augustines, when he finds out Maggie was killed by Damon, and that the people who knew that he was dead didn't mention anything to Damon.

Enzo continues to show acts of loyalty to his friends, mainly Damon, looking for leads to find Damon, and punishing Stefan for giving up on Damon. Enzo clearly misses his friend and even kills Stefan's girlfriend for giving up on Damon, and for making his friend Caroline cry. Enzo is willing to do whatever possible for those he cares about.

Physical Appearance
Enzo is very handsome, with short jet black hair, dark eyes, light olive skin and a solid jaw line. He physically appears to be in his mid twenties despite being nearly one hundred years old. Enzo presents a devil may care attitude in his appearance and is always seen with a cocky smirk, much like his close friend, Damon Salvatore.

His style consists of darker clothing; black shirts, scarves and thick jackets, boots underneath darkened jeans and black trousers, although on occasion has been seen wearing lighter colors, which in general is a "bad boy" style.

Powers and Abilities
Enzo possesses all the standard powers and abilities of a non-original vampire. Furthermore, having been the Augustine's' "lab rat" for more than 50 years, Enzo exhibits surprising resilience due to having endured countless horrific experimentation's during his time in Augustine. He was observed impaling himself with a wooden shaft with no visible signs of discomfort, as well as being able to momentarily ignore the effects of a concentrated vervain shot used on him by Tripp. He is also strong enough to fight Stefan on equal grounds as well as Damon, though Damon stabbed him with wood to momentarily weaken him.

Weaknesses
Enzo has the typical weaknesses of a non-original vampire.

Attitude towards humans
It is unknown what Enzo's original views on humans were but after years of torture, Enzo seems to have little respect for human life. He has fed directly from them and did not show any remorse when attacking or killing people. He did however fall in love with a human named Maggie James, and was unwilling to turn her when she asked him to help him escape Augustine. Instead, he compelled her to forget and leave him, not wanting to see her harmed or corrupted by becoming a vampire.

Name
Lorenzo is a Spanish and Italian masculine given name of Latin origin derived from the name Laurentius. It is used in Spain, Italy, and other Latin European and Latin American countries. Enzo is of Italian and Old German origin, and the meaning is "home ruler", variant of Henry.
