Darnell Da II (or as his birthname would suggest, Darnell Lestor Michaels) was born to Darnell Da I, or better known as Darnell Senior. Darnell Senior was part of a gang and wanted to escape the gang life. He was pursued by federal agents across the country before he fled to europe. There he raised his son up by himself, teaching Darnell Da II how to fend for himself, how to use a gun, and how to kill. When the outbreak broke out, Darnell Senior died to the infected. His last act was to sacrifice himself so that his son could escape through the top floor of their apartment, and jumping on a plethora of pillows. 

Darnell Da II was alone and lost in the strange country of Norway. He raided a police station and found some guns to defend himself with. From there he set out to survive.
