Solidus Snake is the main antagonist of Metal Gear Solid 2: Sons of Liberty. His name is derived from the literal meaning of solidus, the exact point (or "/") between solid and liquid.
He is the third clone of Big Boss, created from the same government project that also created Solid and Liquid, and is an exact DNA duplicate of genetic father. He is first mentioned by name in the original Metal Gear Solid, where he is revealed in the game's cliffhanger ending to be the U.S. President at the time (George Sears)and the mastermind behind the Shadow Moses island incident. After the events of Metal Gear Solid, Solidus resigns his presidency and goes into hiding after being targeted by his former organization, the Patriots.
During the Plant chapter, he leads the terrorist group "Sons of Liberty" while claiming to be Solid Snake and confronts Raiden (who is revealed to be a child soldier he once trained) several times, culminating in a sword fight atop Federal Hall in the end of the game.
He is killed when Raiden saws through his exoskeleton's spine with a high-frequency blade, making him lose control of his body and plummeting down the roof.
In the game, he wears a black exoskeleton suit with mechanical tentacles known as "snake arms" attached to it, and wields a daisho (Katana and Wakizashi set) named Minshuto and Kyowato (Democracy and Republic). At one point of the game, he suffers an injury from a plane crash which takes out his left eye and is forced to wear an eyepatch, resembling his father, Big Boss.
