Forgotten Snake

"I was born as nothing but a replacement of a man.... a dead man. As if that's not worse enough, they took me from my mother, and then killed her. They thought they could control the monster they had created... they are wrong. 

Forgotten Snake (Real name: Isaiah) is the leader of the underground PMC Rough Knights. He was a direct clone of the world's legendary solo operator, Big Boss

As his gene was replicated from Big Boss, Forgotten Snake possessed natural combat talents and personal traits similar to the legendary soldier. However, due to the realization that he was 'created' as nothing but a pawn of a politic game, Forgotten Snake showed more bitter and cruel attitude than his predecessor.

Origin
After the Big Boss' death in 2014, several agents of the Patriots recovered his body to once again create a clone of the world's greatest soldier by using a top-secret invention known as PANDORA, which is actually an advanced exwomb technology. After he was born, Isaiah was put under care of a military doctor named Andrea Fields. As the time went by, Fields saw him as her own son, while Isaiah considered her as his real mother. This caused quite concern between the Patriots' brass. When he was 16 years old, Isaiah was taken away from Fields and put into military academy by the US government, beginning the long process of his journey as a soldier.

After finishing his education, he was inducted to the USMC and made his way to the Force Recon. After showing great performance and potentials, Isaiah was transferred from the Force Recon by US government to Ghost Recon, where he teamed up with three Ghost Operators - Ryder, Sight, and Hawk. During his career in Ghost Recon, he managed to single-handedly assassinated a rogue CIA officer named Thomas Burke, after his teammates were killed in an black-op mission in Congo, earning him the reputation as 'Son of the Big Boss'.
