Usopp is a liar and likes to play pranks on his crew members or just goof off with Luffy and Chopper. He loves to tell tall tales to Chopper (who believes him blindly) or anyone who's listening. The other aspect of Usopp besides his lying is his cowardice; he is a very timid person, or so he thinks. In extremely stressful situations, Usopp has proven to be far more courageous than he believes himself to be. He shows great resolve when his friends are threatened or mocked by outsiders. Even though he is a complete coward in battle (except as his alter ego, Sogeking), he is a useful part to the Straw Hat Pirates. He is extremely handy and can fix almost anything. He sometimes sees a role model in Zoro who never seems afraid but always proud. Usopp lacks a bit of self esteem and is often taken advantage of by Nami to make her weapons or repair and improve them - something he is very adept at, having constructed the ingenious weapon "Clima Tact."
