The Original werewolf-vampire hybrid, Niklaus Mikaelson, is immune to natural death, physical aging, diseases, the negative effects of sunlight, and werewolf venom.
An Original Immortal Tribrid is a rare species that was formed in 2027 by the death of Dianna Mikaelssen, who is the only known member of this species. An original immortal tribrid is a combination of an original vampire, a werewolf, and a witch.
What Did Klaus Do All His Life? Klaus was well over one thousand years old when he died so he must have seen and experienced many things, no doubt, even if he spent a better part of his life running from his father who wanted to kill him.
Even newborns and werewolves can. Klaus can even take a nuke, blackhole but can't take a heart-aimed Whiteoak stake. They are not bulletproof but have high piercing resistance and a regenerative healing factor.
After training with his father, Klaus could now revive himself almost instantly. However, he lost this ability after the universe was reset, making him mortal again.
Mikael has proved many times that he's stronger than Klaus, and of course much more powerful than his other children. Many fans have questioned this detail, but it makes sense. Mikael was already a revered Viking warrior when he was turned by Esther into an original vampire, while Klaus was an untriggered werewolf.
Ever since the siblings Klaus, Elijah, and Rebekah Mikaelson landed on the shores of New Orleans, they have been fighting to claim the city as their own. They are the oldest vampires in the world, trying to share the city with the witches and the werewolves.
Klaus is about 3-4 years younger and according to a s2 flashback on tvd he was possibly born around March (but that could be ignored) making him at most 20, since if Elijah is 24 he would have just turned so. Kol is about 2 years younger making him at most 18, Rebekah at most 17.
Freya Was the Best Mikaleson Sibling
Freya being the best Mikaelson sibling is a no-brainer. However, for additional arguments, here is Freya's backstory to refresh our minds and some valid points to prove what we all know. Esther was initially barren, which led her to strike a deal with her evil sister Dahlia.
Super Strength: The Original Tribrid is much stronger than Immortals, Supernatural Hunters, non-original vampires, werewolves, non-original hybrids, and humans. They even possess enough strength to overpower an Original Vampire.
This was a predicament Klaus Mikaelson, Hope's father and first supernatural hybrid, struggled with in his quest to create more vampire-werewolf hybrids. However, Hope is the only vampire-werewolf-witch tribrid that Nature has ever allowed to exist.
With the death of Mikael, Klaus Mikaelson, Elijah Mikaelson, Lucien Castle, Alaric Saltzman, and Finn Mikaelson, Hope is now the strongest creature on the planet only rivaled by the last remaining Originals ie; Rebekah and Kol Mikaelson but possesses an edge over them to her hybrid nature and her only equal is possibly ...
Mikael Mikaelson. As the father of the Original Vampires, he was the oldest and the most powerful vampire in the TVDU universe. Mikael was Esther's husband, Dahlia's brother-in-law and Klaus's stepfather. He was the father of Freya, Finn, Elijah, Kol, Rebekah and Henrik.
So yes, Klaus is immortal for the majority of The Umbrella Academy. In fact, he dies and comes back to life countless times throughout the rest of the season, including a disturbing sequence where Reginald (Colm Feore) trains him and he gets hit by cars and trucks in the middle of the road repeatedly.
Henrik Mikaelson: Henrik was the last and seventh born child of Mikael and Esther, the younger brother of Freya, Finn, Elijah, Kol and Rebekah and the younger half-brother of Niklaus. Henrik was the youngest sibling and child of the Original family.
Freya Mikaelson - Freya was Mikael and Esther's first born child, and the oldest sister of Finn, Elijah, Kol, Rebekah and Henrik, and the half-sister of Niklaus. It was said that the oldest Original sibling had died in the Old World (specifically Norway) because of the plague.
Freya is the firstborn child of Mikael and Esther, the elder sister of Finn, Elijah, Kol, Rebekah, and Henrik, the maternal older half-sister of Klaus.
Different: Age and Power
Klaus, as an original vampire and a hybrid, is much older and more powerful than Damon. Klaus sired many vampires, and he is Damon's vampire ancestor.
Although his brother Klaus might technically be stronger — Klaus is half vampire, half werewolf — Elijah is the most powerful. Other traits to note: He is level-headed.
Freya is no longer immortal, but she can be. Remember back in the end of season 2 (Honestly, it wasn't even that long ago), when Dahlia used a connection spell to link her and Klaus' power?
This is the family relationship between the original vampire, Elijah Mikaelson and the mortal tribrid, Olympia Mikaelson. Olympia is Elijah's only biological child and is the daughter he had with his wife, Dianna Mikaelssen.
With all of this in mind, it is important to note that Rebekah is the weakest Original Vampire, I wouldn't necessarily say because she's female, but for the sake of this argument, it's worth noting this, but at the end of the day she might have simply been the weakest child of Esther (strength-wise), and not because ...
For pretty much all of Klaus' vampire life, Mikael was the only man who was physically capable of fighting Klaus, who actually had the drive and determination to kill him, and most importantly had the only weapon that could actually kill Klaus.
Cover made by @July-is-Life Niklaus Mikaelson has a weakness that only his siblings know. That weakness is that Klaus still feels guilty about what happened to his beloved younger brother, Henrik Mikaelson. The male Mikaelson believes that it is his fault that a werewolf killed Henrik.
