Phantom

The Phantom is an international spy working for an unknown organization. His true identity is unknown as he is a master of disguise. Using his abilities, he managed to impersonate the deceased Bobby Fulbright so any evidence of his identity and him killing psychologist Metis Cykes can be erased.

The Phantom is a skilled actor and a master of disguises, to the point where he never actually reveals his true face beyond his collection of masks, instead speaking through his impersonations of others, favoring Phoenix Wright after his identity theft of Fulbright is revealed (given how Wright was interrogating him in court at the time, this was likely an intimidation tactic). He also has a fondness for spy gadgets (including a grappling hook and a jamming device he uses to confuse Athena Cykes' Mood Matrix), many of which are built into his watch.

He is an emotionless person by nature, and this fact would be used against him. After finally being cornered by the defense, the Phantom reveals some of his remaining humanity by expressing immense fear, tearing off his masks one by one and questioning who he ultimately was.

At the end of his breakdown, he is shot by an unknown sniper. However his wound is not fatal, and the Phantom was finally arrested, bringing closure to the UR-1 incident.

Development

 * The Phantom is the first villain of the series who has no real name or identity, with the only things known about him is that he's an international spy with almost no emotions. This is due to him having lost any premise or idea of what his true face and identity actually are. This makes him the first villain whose true identity is never found out or revealed to the player, although it can be argued that he doesn't have an identity to be revealed, due to even him himself not knowing what that is.
 * This also marks the first villain, ironically, who's brought down using pure emotions, despite one of his traits being that he doesn't feel most emotions. In the end, it's the fact that he's a human being like everyone else that ends up being his downfall.
 * The Phantom is never referred to as "Phantom" when speaking. The text box always uses the name of the person he is disguised as, "Phoenix?" when disguised as Phoenix Wright, or "???" when he's changing masks.
 * He is the second impersonator of Phoenix Wright, although this time around, it was known that it was an impostor by the time he put the mask on. Also, it was a much better act than previously.
