Clarisse La Rue

Clarisse La Rue is the secondary tritagonist in the 2013 film adaptation of The Sea of Monsters. She is the daughter of Ares and a rival-turned-friend of Percy Jackson, as well as savior of Thalia Grace's tree.

She is portrayed by Leven Rambin.

Personality
Clarisse is stubborn, determined and tough due to being the daughter of Ares, the god of war. She often teases Percy and has a not-so-friendly rivalry with him.

Despite her rivalry with Percy, they eventually come to realize that they are not so different because of their need to prove themselves to their fathers and be the best they can at camp. Clarisse also cares for the well-being of the camp, showing that she can be rather protective of her friends and her home, as she goes on the quest to save it. She also expressed genuine concern AND horror when Annabeth was poisoned by the Manticore and showed relief when the Golden Fleece saved her, as well as Thalia Grace.
