Mimic

Harry has always had a talent for mimicking voices. He could make his voice sound like anyone he wanted it to sound like, be it male or female, with just a little practice on his part. Then when he found out he could also shift his features to look like anyone he wanted to as well, Harry knew that he had something that could save him from the hell that was his so-called family; he had something he could finally use to make a name for himself with. Now, years later Tsuna, and his new guardians, are going to meet up with the now world-famous hitman and assassin only known as The Mimic.
