In the official The Vampire Diaries television series, Elena Gilbert is not a tribrid; she is a human, then a Petrova doppelgänger, and later a vampire. While fan fiction (notably in the "Alex Gilbert" series) often explores storylines where she becomes a tribrid, the canon storyline does not support this.
In the season finale, she became a tribrid despite never wanting to be one.
It is revealed that Elena is a Petrova Doppelgänger (like Katherine, Amara and Tatia), which is thus responsible for her being identical to her ancestor, Katherine Pierce (née Katerina Petrova). This also has the implication of making her a supernatural creature.
Tribrids are a cross-breed of three different supernatural species. The term is commonly used to describe a vampire-werewolf-witch tribrid. Tribrids possess both the strengths and some of the weaknesses of their parent races, along with powerful attributes unique to themselves alone due to their combined heritage.
Elena Michaels is the female lead and protagonist of Bitten. She is the only known female werewolf in the world, the fiancée of Clayton Danvers and the ex-girlfriend of the late Philip McAdams.
Dominic Toretto had a brief fling with Elena Neves, but how does the Elena Fast and Furious timeline line up with the rest of the franchise concerning Dom's son? Despite Dom's romantic history with Letty Ortiz throughout the Fast & Furious franchise, he became a father to Elena's baby.
The seven original vampires, known as the Mikaelson family from The Vampire Diaries universe, are Mikael, Esther, Elijah, Niklaus (Klaus), Finn, Kol, and Rebekah, the parents and their six surviving children who became the first vampires after their youngest brother Henrik's death, created by Esther's magic using white oak wood, making them incredibly powerful and nearly indestructible, only vulnerable to the white oak stake.
Adrianna, Hope, and Alexia are the only tribrids in existence. Adrianna is not a naturally born tribrid. She was a loophole, only made possible due to Irene's spell. To become the Original Tribrid, Adrianna cast a modified version of the Immortality Spell on herself before she was killed after giving birth to Hope.
Stefanie Rose Salvatore is a recurring character on Legacies and a former guest starring character on The Originals. Stefanie is the witch daughter of Damon Salvatore and Elena Gilbert, the younger sister of Jenna, Grayson, and Bennett Salvatore, and the older sister of Sarah Salvatore.
The sleeping spell she's locked in stops her aging. But that is just temporary immortality, which means that the only thing stopping her from aging 60-odd years will be the cure in her blood.
Katherine and Elena both were from the Petrova bloodline but Elena isn't a descendant of Katherine. Elena would be from an older sibling of Katherine's or a cousin, but still of the Petrova name. Same for Amara and Tatia.
Tribrid is a type of Hybrid with a combination of the three supernatural species. Famous tribrids are Damon, Marcus, Candice, Catherine, Nina, Celina and more throughout the series. Damon and Marcus are witch-archangel-sirens, what makes them the most powerful tribrids ever known.
And ultimately, Dobrev made the decision to walk away after season six. However, she returned for the series finale in 2017 but even that was limited due to salary disputes. "The reason we couldn't have her for more than the one episode," Plec said, "is because they just wouldn't pay."
Sarah Salvatore: Sarah is the middle tribrid child of Theo Salvatore and Elena Gilbert. She was born on February 11, 2015 , Mystic Falls, Virginia. She attends the Salvatore Boarding School. Sarah is the distant descendant of Silas and Amara.
Julie Plec confirmed that Klaus is the origin of the bloodline Stefan, Damon, Caroline and Elena are from. It is possible to unlink a vampire from their bloodline using magic. This was successfully performed on Klaus by Davina.
When they say Hayley is the first unsired vampire, they mean that it wasn't a vampire from one of the original siblings bloodlines that made her. It was Hopes blood. Hopes blood is special and isn't tied to any of the original bloodlines from which all other vampires are descended.
Procreation: Sophie explained that Klaus was only able to procreate due to being the Original hybrid — a born werewolf, turned into a vampire by magic — Nature's loophole. This has since been made impossible.
Weaknesses. Immortal tribrids can be killed via decapitation and heart extraction. If an immortal tribrid is bound and deprived of their werewolf nature they can then burn to death in the sunlight with a daylight amulet.
Tatia, originating in the 10th century AD, was the first true doppelgänger following Amara's immortality. She is a member of the Petrova doppelgängers, a lineage initiated by Amara, the eldest known forebear of the Petrova Family.
Premise. Legacies follows Hope Mikaelson, the daughter of Klaus Mikaelson and Hayley Marshall, who is descended from some of the most powerful ancient, original vampires, werewolf, and witch bloodlines.
Jure Grando. Jure Grando Alilović or Giure Grando (1578–1656) was a villager from the region of Istria (in modern-day Croatia) who may have been the first real person described as a vampire in historical records.
