Called a young genius prosecutor, he has never allowed a not-guilty verdict in the courtroom for any case he has handled. On the other hand, he deeply despises criminals, and has a reputation for using any means necessary to secure a guilty verdict.
Calm, composed, and brilliant. However, he also has a clumsy and somewhat airheaded side, and struggles with conversations beyond work. He has a strong sense of responsibility and cannot tolerate his own mistakes more than those of others. Though a genius in both name and reality, he has a habit of misremembering the names of buildings and objects used as evidence, as well as people's names.
He excelled in both academics and athletics since childhood, but is terribly clumsy with his hands; apparently, in elementary school, he couldn't even fold a paper crane properly.
True to his flashy attire, his office is furnished like an aristocrat's, and his private life apparently matches that aristocratic image as well.
He seems to spare no expense on his hobbies, with tea that is a custom order costing more than a certain detective's monthly salary.
He owns a bright red sports car, but avoids wasteful spending, even on something as small as a piece of gum.
Due to trauma from a past case, he has a weakness for earthquakes. When an earthquake occurs, he crouches on the floor trembling, and in severe cases faints or has difficulty breathing. He can ride them, but he also dislikes elevators due to the influence of that case. He has even passed out from turbulence inside an aircraft, which once led to him falling under unwarranted suspicion.
In the story, a certain woman points out that he is naive about romance, and considering that no mention of romantic experience ever comes up, his experience with women may be quite limited. He might even be a virgin.
He lost his father in early childhood and was taken in by a prosecutor named Manfred von Karma, becoming his disciple.
He has a fellow-disciple relationship with Franziska, Manfred's daughter, who is seven years younger than Miles, and they are like adoptive siblings.
A tall, slender young man of striking appearance, very popular with women. He is 178 cm tall.
He often crosses his arms when deep in thought. When showing composure or cornering an opponent, he tends to spread both arms in a "well, well" gesture or raise a finger and wave it before his face—mannerisms that give him a more elegant impression compared to his rival attorney.
But this is Ace Attorney, after all. When flustered, he puts on exaggerated facial expressions like any other character.
His attire consists of a wine-red suit worn open over a black vest. A white jabot (commonly called "frills") around his neck is his signature feature, and combined with his somewhat flashier clothing compared to Phoenix, those frills are frequently made fun of in the series. Incidentally, this flashy fashion is a direct tradition of the von Karma family, and he takes pride in it; the suits are custom-made by the von Karma family's personal designer.
He does not wear his prosecutor's badge, keeping it in his pocket instead (in the world of Ace Attorney, Manfred von Karma spread the idea that not wearing a prosecutor's badge is more stylish). However, according to Mikumo Ichijou's testimony, he loves showing off his prosecutor's badge to his partner, making him just like his edgy, blue-clad best friend in that regard.
