""Black Diamond" was the fight name chosen by Adriano after he signed his first international MMA contract. Moraes was abandoned by his mother when he was a baby, left in a dark alley and found by a passer-by who took him to an orphanage. He was later taken in and raised by foster parents, and his nickname was chosen with those experiences in mind. Like a black diamond, found in the middle of nowhere and shaped into a shiny valuable work of art. He is also known as "Mikinho" from his capoeira days with Master "Esquilo" when he was a child, a name given to him due to his small size and agility."
