Oc Mikaelson
Oc/Reader Is the second oldest Mikaelson.
When he and his siblings were turned And he and Klaus made their first kill their werewolf curses activated.
And it was replaced that he and Klaus were products of an affair with werewolves ( they can be separate father's or they can share the same father making them full siblings)
Their mother performed a spell that suppressed their werewolf sides.
Throughout the years since he was turned into a vampire
Unlike his siblings he had a better control of his hunger and bloodlust.
He came up with the system of compelling a human drinking and then compelling for them to forget.
Out of his siblings he is the calmest but when he gets angry he channels it and controls it making him more feared then Klaus.
People would rather die by Klaus's hand then his
He is extremely protective of his siblings especially Rebekah as she is his only sister (that he knows of)
He has close relationships with them all expect Finn.
But unlike Klaus he had no problem with Her dating and when she fell in love with a human he would turn the human into a vampire for her, and if the man betrayed her or hurt her he became ruthless when killing them.
Klaus is only afraid of him as being a hybrid he can match his strength,speed etc
