Nico Petit is the titular Phantom. He is the one who performs the actual thefts in Il Dottore's theft ring.
Nico Petit is a skilled thief that left so few clues, he became known as the Phantom. Helena Berg was impressed enough with his skills that she recruited him to be in her theft ring.
Antonio Fango would leave Nico certain Scopa cards that would tell him the next location he should strike. Nico would then speak with Gina to find out what needed to be done on the mission. Once he had stolen the object, he would give it to Enrico Tazza to hide and eventually ship out.
- Helena didn't like him to wear his mask.
