(this is really long so if you make it through the whole thing, you a real one lmaooo) lucien was a friend of klaus when the mikaelsons first became vampires. he was a servant basically to a royal family. he let the mikaelsons know of the families customs so they could hide in that kingdom for a while. lucien and klaus were best friends until klaus basically took lucien’s girl. Aurora. she was the king’s daughter and lucien loved her but she loved klaus and klaus went for her. lucien was the first vampire klaus ever turned. before the mikaelsons left the kingdom, elijah (without really knowing) had compelled aurora, her brother tristen and lucien to believe they were 3 of the mikaelsons (klaus, elijah and rebekah) so that their father would hunt those 3 instead of the actual mikaelsons. the compulsion eventually broke and lucien has had a vendetta against the mikaelsons ever since. there was a prophecy stating that the mikaelsons would die and any vampire turned by them would also die. so lucien came to new orleans to “save” klaus since if klaud died so would lucien. but lucien was actually planning to become their better and was the one who planned on making the mikaelsons die and fulfilling the prophecy. lucien made a deal with the witch ancestors (since they hate the mikaelsons too) and basically would give him access to the regent who could perform the original vampire spell with some additional powers, like a werewolf bite with 7 different venoms that would be faster working and even lethal to an original. he killed cami and he killed Finn mikaelson. the joker smile that klaus cut him is a symbol of their past. Aurora’s brother used to do the same thing to lucien to show lucien that he’s nothing more than a servant. so klaus wanted to do the same kinda thing.
lucien became a super vampire do to a spell of werewolf venom of five legend wolf packs and he had to die to become stronger marcel becomes like lucien in the series season three
