Agent 47
Overview
Agent 47 is the protagonist of the Hitman franchise and the character controlled by the player throughout the series. He is a genetically engineered assassin, created as part of a top-secret cloning program intended to produce the perfect contract killer.
His designation, "47," signifies that he is the 47th clone produced by the project. His identity is marked by a barcode tattoo on the back of his head—640509-040147—from which the last two digits give him his codename. The DNA used to create him was taken from five of the world's most dangerous criminals, each contributing traits such as intelligence, stamina, discipline, and ruthlessness. As a result, Agent 47 possesses superior strength, speed, agility, and tactical reasoning, making him superhuman.
Raised and trained from birth within controlled environments, 47 was shaped into a flawless operative—emotionless killer, highly observant, and masterfully skilled in stealth, disguise, and assassination techniques. He becomes the ICA's (International Contract Agency's) most effective and reliable assassin, maintaining the position of their top operative for many years. His professionalism, quiet demeanor, and methodical approach contribute to his reputation as one of the world's most lethal and elusive killers.

Name: Max Walker
Age: 15
The abilities/skills he currently has:
• Superior physical condition:He is able to defeat any average professional athlete in any physical competition.
• Slow aging:As the name suggests, he ages extremely slowly. Even at 60 years old, like Agent 47, he would still look as if he were in his physical prime.
• Minor healing factor:He can survive multiple gunshot wounds and fully heal within a few hours, depending on where the bullet hits.
• Superhuman instinct:He can predict the movements of others, even if they are hiding behind walls hundreds of feet away, giving him an almost X-ray-like sense of awareness.
• Superhuman senses:He can see, hear, and smell many times better than the average human. If he focuses, he can even hear a person's heartbeat.
• Superhuman aim:He can throw or fire any projectile with pinpoint accuracy, essentially giving him "aim-hack"-level precision.
• Minor emotion suppression:He can remain calm even in dire or life-threatening situations.
• Fast learning:He can learn many times faster than an average person. What might take someone a few years to learn, such as a new language, would take him only a few weeks.

There won't be a harem in my story because I'm terrible at writing one, and honestly, it doesn't feel logical to include one. The love interest will be Clementine.
