King Xavier

King Xavier is  acharacter on Once Upon a Time and has no Storybrooke counterpart. He is the grandfather of Queen Regina and great-grandfather of Jason Jones-Mills.

He is partially based on the King from the fairy-tale "Rumplestiltskin".

Before First Curse
Xavier is the father to four sons, one of which is named Henry. Xavier is a rich king, but his kingdom is slowly descending into poverty. He later forces Cora to apologize for tripping over Princess Eva, even though it was not Cora's fault and forces her to bow down before them until they leave. During the ball, he sees Cora dance with his son and threatens her. Cora then says she can turn straw into gold, which causes the King to say things: He will lock her in a room full of straw for the night. Should she succeed, he will let her marry his son, but if she should lose, then Xavier will kill her.

He is later impressed by Cora's talent to spin gold and gives her his son's hand. King Xavier brings up her love affair with Rumplestiltskin, whom he know she intends to run away with. During the conversation, he states that "love is weakness" and that marriage is not based on love, but alliances. He tempts her with the option of staying by Henry's side and gaining respect as a royal.Later, Cora decides to go to rip Xavier's heart, but then changes her mind by taking out her own heart.

Sometime later, Cora and Henry have a daughter together. Xavier asks what his granddaughter' s name is and Cora says her name is Regina and she will one day be queen.
