Elijah Mikaelson is the Only Original Vampire who is equal to his younger brother Niklaus Mikaelson, the Werewolf + Original Vampire Hybrid. They're an even match. Both are extremely dangerous Vampires, Klaus has Werewolf powers and abilities, and Elijah has a more strategic mindset + fighting techniques + red door.
You guys say Kol will not deal with Klaus when in the Original there were tie to tie the only time I say Klaus beating Kol in seconds is if he went hybrid mode
Klaus did keep his word with Elijah in a loophole way but he told him the truth that he would reunite them and did and that the family is not buried at sea but Elijah tried to kill Klaus off for good though before hand yeah.
