Given the question: Who was banished?  Answer the above question based on the context below:  Somewhere in the 17th century, after attacking and boarding one of the Kingdom of Monterria's ships, the pirate Robert the Terrible captures the Prince Alexander and sends his men in search of Princess Eloise. Eluding the pirates, Eloise and her servant Willory emerge and send a device that the king made, called a "Helpseeker," to find heroes to save Alexander. In modern times, three misfits: the "yes man" George, the lazy Sedgewick, and the timid Elliot (Larry the Cucumber) are employees at a dinner theater. Although they want to be seen as heroes by their loved ones, as lowly cabin boys they think their dream is unattainable. After wrecking the show, they are fired and thrown into the alley, where the Helpseeker locates them. Elliot activates the device, transporting them to Monterria. Meeting Eloise and Willory, the group sets off to Jolly Joe's Tavern where they learn that Robert, the brother of the king, has kidnapped Alexander in the hopes of exacting revenge on his brother, who banished him. Setting sail in search of the whereabouts of Robert's hideout, the pirate's men capture Eloise and Willory. As George and Elliot continue on their quest, a cowardly Sedgewick decides to stay behind in a cave filled with "cheese curls", afraid to face Robert. After the two leave, however, Sedgewick discovers the curls are living worm-like creatures and is chased out of the cave, overcoming his fear and laziness along the way.
The answer is:
Robert
