Apollo Justice is largely characterized by his seriousness and desire to build his self-confidence. He deals with the bizarre situations that are thrown at him by being somewhat sarcastic and critical toward others, including some of his clients. This often puts him at odds with people like Klavier and the Wrights, who often tease him and make him wonder if he is being taken seriously. He frequently makes puns out of his own name and practices shouting for hours at night, calling it his "Chords of Steel", which sometimes makes his voice raspy. While mostly to "improve" his voice in court, these exercises also function to both psyche himself up and make himself feel better. Apollo often uses the phrase "I'm fine!" as a way of psyching or cheering himself up, with his friend Clay Terran also developing this habit.
