King Frederic

The King is the father of Rapunzel, and the husband of the Queen in Disney's Tangled featuring Flynn Rider and Rapunzel.

Biography
There is no specific backstory dedicated to revealing how the King rises up to rule the kingdom. Though, it would appear that he is very much liked and supported by the kingdom and the denizens that reside within.

Tangled
Father to Rapunzel, and husband to the beautiful Queen, the King is the ruler of Corona. He is first seen by his wife's sickbed while she is heavily pregnant with their daughter, and lighting the lantern with the Queen later on after Rapunzel's birth. Every year on Rapunzel's birthday, the King and queen release a lantern fo their daughter. The King does not return to the scene until towards the end when Rapunzel returns to reunite with him and the Queen. He is then seen again smiling and hugging Rapunzel and the Queen. Although the King, like Queen and many other minor and supporting characters, does not speak, he has vivid and lively facial emotions and body languages that loudly and clearly express his thoughts and ideas.

Tangled Ever After
In the short film, Rapunzel and Eugene's wedding day has finally arrived. The King is obviously present the day of, and walks Rapunzel down the aisle.
