Les Enfants Terribles is a top secret project that was to take the genes of the world's best soldier and manipulate those genes to create the perfect soldier. It originally had 8 genetically enhanced children, but six were supposedly killed to obtain the dominant genes of the group, producing two super soldiers. Their names, Liquid Snake and Solid Snake. But unknown to the both of them, there was actually a third super soldier, and he is rumored to be better than the other two, the actual success and product of the project. His
name, Solidus. Solidus is a mysterious figure, little to nothing is known about
him, his origin, his cause, etc. All we know is that he is probably up to no
good. We will have to wait and see, because we have very little info on this
character.
