Shinkawa's Snake design features a dark grey bandanna, a consistent "sneaking suit", and the effective voicework of Akio Ohtsuka for Japanese versions and David Hayter for English versions of Metal Gear games as Snake's defining aspects. The character underwent an eight-year hiatus, until the release of the seminal Metal Gear Solid for Sony PlayStation in 1998, which fully established Solid Snake in his more popular, modern-day character design, which was made by artist, Yoji Shinkawa (see his above artwork). Snake's name, in fact, was derived from Escape from New York's main character, Snake Pliskin, and his real name, "David" serves as a reference to the astronaut David Bowman from "2001: A Space Oddysey" (whilst simultaneously referring to Dave Forrest, a character from one of Kojima's earlier games, Policenauts.) When Metal Gear was ported to the NES, it sold well enough that Snake subsequently appeared in the sequel, Metal Gear 2: Solid Snake. Kojima's main character for the game, codenamed Solid Snake, was likewise inspired by the heroes from those action movies, such as Kyle Reese (portrayed by Michael Biehn) from The Terminator, whom Snake's first portrait and the cover art of the original Metal Gear was based on. Metal Gear franchise creator, Hideo Kojima, started off his franchise with the first Metal Gear for the MSX2 computer in 1987, as a pastiche of high-profile action movies at the time, such as Lethal Weapon and Escape from New York.
