Maybe its not Big Boss the other guy, maybe it is Liquid, cause he is his damn clone.
And this ninja looks so much like Raiden and a little with Gray Fox.
In internet you can find people saying about being: Little John (Raiden's Son) or Sunny (Olga Gurlukovich's daughter)

But I think is Gray Raiden (=

Take your own conclusions:
In the blog [girlsofwars] I read about a theory of something wrote in French at the hat of pseudo big boss.
“Militaire Sans Frontieres” that means “Soldiers Without Borders”.
Also they speak about a book of Special Air Service -SAS- soldiers called 'Soldiers without Borders'.
Liquid Snake lived in England and was from SAS. Remembering that Liquid Blond hair is painted. ;)

And with all that thunders and storm... for damn sure: It IS Raiden.
