Prince Hans of the Southern Isles

"'Oh Anna, if there was only somebody out there who loved you. See, as thirteenth son I never really had a chance at my father's throne, so my plan was to marry Elsa and become king. But then, you came and were ready to marry me right away. Now I just have to arrange a little accident for Elsa and let you die here, and I'll be king...'"Prince Hans of the Southern Isles is the thirteenth son of King George of the Southern Isles and a former fiancé of Princess Anna.

History
Hans was bullied by his elder brothers (except for Lars) for his entire life.Most of them were married before he reached adulthood. This made him hungry for power, so he went to Queen Elsa's coronation to court her and be king but she turned him down. He asked her younger sister Anna for her hand and she said yes.

When Anna was nearly dead, he finally revealed he didn't love her and was about to kill Elsa, but Anna stopped him and recovered. He was send back to The Southern Isles for his punishment.

Return and punishment
"'You begged me to let you go to represent our kingdom. You almost killed two of Arendelle's princesses and the kingdoms reputation. You are not a son or a prince. You're a disgrace. You were more useful when you were invisible...'"

-Queen Allowyn to her youngest son-
Upon return home he was immediately stripped of his title, money and claim to the throne of the Southern Isles. He was put in prison for two months before he came to work as a stable boy at his parents estate.

King George wrote Queen Elsa a letter explaining he and Hans' brothers cut all ties with him and apologized for his behavior. The King also requested that Arendelle wouldn't unleash a rage towards the Southern Isles.

Trivia

 * He may have possible magical powers. What those powers are a dark mystery, if he has any.
 * Given he was born in the year without a summer and his status as the 13th son, many considered his birth to be a bad omen, a warning sign of future negative events.
 * It's also possible his birthday was marred by a bad event such as drought, famines, war, etc. Though not at fault for said incident, he was inextricably linked with that terrible day for the rest of his life, and because of that, he was treated like a villain until he became one.
 * His family wanted to have a girl after 12 sons, but instead, they got a baby boy, causing them to tag him with nicknames such as the "mistake who wasn't meant to be born," "an useless spare," "the runt of the litter," "the baker's dozen," "the throwaway," or an "extra mouth they did not want to feed."
 * It's also possible that they bullied him for no reason other than being ineffectual.
