Apollo Justice

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.

Ultimately, Apollo is determined about his job, and cares deeply about his friends and clients. For example, he cried in relief after finding out that Trucy was safe following her "abduction", as well as when Vera Misham survived her atroquinine poisoning. After Clay Terran's death, Apollo developed a cold demeanor and withdrew from those close to him, overwhelmed by his anger and suspicion of Athena, which she sensed when he announced his leave of absence. However, he still wanted to believe in her and make sure that he could trust her. When discussing the change, Trucy mentioned that it was unlike him to be so "cool and mysterious".

When talking about newspapers, Apollo has admitted that he only reads the funnies. He claims to be good with astrology and hula hoops, and used to watch a certain science-fiction show, which he was reminded of when Trucy used the phrase "bigger on the inside than on the outside" to describe her top hat. While preparing a case overnight, he used to have instant noodles, crackers, and manga on his desk; he claimed that the latter is for research, because they were "super realistic and informative". He shares Phoenix Wright's fear of heights and disinclination to drive, preferring biking instead. He also dislikes loud music and is unable to swim.
