"Ace Attorney" and main character of the first three games, Phoenix has wanted to be a defense lawyer since he was a kid, and first appears as the new addition to Mia Fey's law practice.
Phoenix is generally easy-going, which usually leads to his friends leading him around. He's dedicated to defending his innocent clients, but because he's just starting out he depends a lot on his boss and mentor, Mia Fey. Phoenix is also a loyal friend who won't back down once he's set his mind on something. He has a bit of a sarcastic side that he usually keeps to himself.
Director Takumi speculates that before studying to become a lawyer, Phoenix may have gone to college to become a Shakespearean actor. Character artist Suekana, however, prefers to think he would have been a manga artist.
Phoenix is an only child, but he's close friends with Larry Butz prior to the game, and is Mia Fey's employee. No reference as to his parents.
