Serpent Pliskin (Metal Gear Solid 5: The Phantom Pain)

It was from him that Solid Snake was copied. Just in case.

first movie or second?

Separ
First of course. But it doesn't matter, because he is there and there.

you did not understand my question

Separ
Explain please.

Who is he Serpent Pliskin?

Neither Big Boss nor Solid Snake have the last name Pliskin?

Separ
Solid Snake has the alias Iroquois Pliskin.

But after all, Carpenter's script was written long before Kajima's games - 78 - the first scenario of the escape from New York - and it is the Serpent Pliskin who is present there

Separ
Kojima was inspired by Escape from New York, so he gave his character (Solid Snake) the surname "Snake".

Not a name, but a callsign ...
