Sleeping Beauty
King Stefan and Queen Leah are the monarchs of an unnamed Kingdom. He is overjoyed when his wife gives birth to a baby girl whom they named Aurora. The whole kingdom was invited by Stefan to celebrate her birth. But his and his queen's happiness is short lived, as the evil fairy Maleficent, the only person not invited to Aurora's celebration, enters his castle and curses the baby. She then prophecizes that on Aurora's 16th birthday, she will die from touching the spindle of a spinning wheel although after she leaves, one of the Three Good Fairies weakens the curse so their daughter will sleep instead of death. The King and Queen make the hardest decision of their lives: their daughter must be raised by the Three Good Fairies away in the forest in order to protect her. King Stefan ordered all spinning wheels in the kingdom to be burned in an attempt to prevent the curse from happening. The narrator reveals that sixteen sad and lonely years passed for he and his queen. Sixteen years later he is waiting his daughter's return in the Castle. When Aurora touches the spindle, the Good Fairies put everyone in the Kingdom to sleep. When Maleficent is defeated by Prince Phillip, he awakens and finally meets his daughter.

Maleficent version
King Stefan is a character in the feature film Maleficent and the main antagonist, portrayed by actor Sharlto Copley.

Maleficent
As a child, he was poor, had no family and often stole things. He first met Maleficent when he escaped to the Moors after stealing a gem. The two became close friends until the day he stole her wings so he could lie that he killed her and become the new king. He married King Henry's daughter Princess Lelia and together they had a child of their own, a baby girl they named Aurora.

However, his treacherous actions would cost him dearly as Maleficent placed a curse upon his daughter Aurora as revenge for what he did to her. Over the next sixteen years, Stefan became extremely paranoid and obsessed with hunting Maleficent down, so obsessed that he couldn't care less for his dying queen.

When Aurora returns on the day before her sixteenth birthday, he has her locked up, but she finds her way to the dungeons where the spinning wheels were burnt and pricks her finger, putting her into her deep slumber.

Stefan and his guards capture Maleficent and Diaval. He ruthlessly takes his time torturing her and just when he's about to kill her, Maleficent's wings return to her, thanks to Aurora. He is quickly overpowered by Maleficent and even though she spares him, he still vows to kill her. The two fall from a tower, but Maleficent manages to become airborne and leaves Stefan to fall to his death, ending his rage forever.
