Ok, "The Master" it's not really a nick name... It's my battle name that I've used when I was served in Italian Army and my nickname too. Also, in the real life, the 99% of the people call me "Master"
It was taken from the state-of-the-art Metallica's album "Master Of Puppets", the first that I've listen before to become a banger, and someone gives this nick to me thinking 'bout the "power" of command that I've reached during my Military service... And thanks my bad character

'cause I'm hard as a ram XD
