Prince Fabious is the deuteragonist in Your Highness. He is the heir to the throne in the Kingdom of Mourne, and goes on a quest with his brother to rescue his bride-to-be when she is captured by an evil warlock. Fabious is portrayed by James Franco, who also played Harry Osborn in the Sam Raimi Spider-Man films.
Fabious was born as the first born son of King Tallioius and his unnamed queen, who presumably died, being the oldest Fabious was destined to succeed his father as king of Mourne. As a child Fabious, was friends with the Great Wise Wizard and had sleepovers with him but kept it a secret from his father. At some point Fabious meet and became best friend with Boremont, whom became second in command of his Knights Elite, had his hand cut off to save him, and had picnics with, unware that Boremont had romantic feelings for him. As a knight, He became enemies with the evil sorcerer Leezar, who threatened Mourne with many monsters, but Fabious was able to slay them. In doing so, Fabious became a well known hero in Mourne and made Tallioius very proud of him but Fabious earned the jealousy of his lazy, arrogant and immature younger brother Thadeous. On 27th quest, after slaying Leezar's cyclops, Fabious also rescues a beautiful virgin woman named Belladonna, whom Leezar kept imprisoned in his castle since she was young. Fabious falls in love with her and decides to bring her back to Mourne to marry her.
Spying on Isabel
Thadeous and Fabious see Isabel from a distance as she undresses herself to go for a swim in the pond. When Isabel catches Thadeous and Fabious spying on her, the two keep their distance and freeze in their positions. She ignores them, dives into the water and swims.
Fabious is a stereotype of medieval knight heroes, brave, selfless, dashing, wise and kind hearted. He is willing to save others no matter what the danger for example he was willing to go back to the camp to save Steven, Thadeoaus' animal companion, after Boremount, Julie and the Knights Elite betrayed them despite the danger. He loves his brother, despite his selfish attitude and jealousy, he was willing to allow Thadeous to be king along side him and was concerned for his well being after Leezar kidnapped Belladonna. However, he has little knowledge of sex.
- Fabious, being the older brother, is ironic, as James Franco, who plays Fabious, is younger Danny McBride, who plays Thadeous.
