Vex Vulper 

Vex Vulper is the secondary antagonist of Ace Attorney: Contempt of Court, serving as the main antagonist of the first chapter, the scapegoat antagonist of the third chapter, and a temporary ally in the fourth chapter.
Vex Vulper was a skilled sculptor who was eager to be like Jack Crane, his step-brother when he was younger. Unfortunately, Crane was working for Quercus Alba's smuggling ring, something he roped Vulper into. Vulper found himself thrust into a world he was completely unfamiliar with, balancing his role as a smuggler with his role as a prosecutor.

Vulper was given a far larger role in the game due to being beloved by fans, originally only being a starter villain. Due to this, he has some of the most screentime out of all the supporting characters, being an important character in three out of four chapters.
Vulper's hair gets longer as time passes. It also becomes more explicitly demonic.
Vex means to annoy someone with trivial manners, a fitting name for such a character.
While he was originally written to be a hate sink, his personality was changed to make him more tragic and three-dimensional, eventually coming across as someone too goofy and complex to truly hate. This means that Contempt of court is one of the few ace attorney games, fangame or otherwise, to have no hate sinks, as even Robert Snow was too entertaining to truly loathe.
Ironically, Vex Vulper and Lyle Hemlock have many similarities. They are both greedy, childish, and great at impersonating other people.
