Maldini's specialty is stealth. At GIS his ability to occupy positions undetected by the enemy resulted in the nickname "The Invisible Man". He is in excellent physical condition and is exceptionally quick on his feet. His demeanor is calm and somewhat aloof. Although a solid team member, he is too introspective to be a truly effective commander. Off-duty he is an amateur marathoner and has competed in races across Europe. Extremely intelligent and well-spoken.
