Militaires Sans Frontières

The Metal Gear franchise features a large number of characters created by Hideo Kojima and designed by Yoji Shinkawa. Its setting features several soldiers with supernatural powers provided by the new advancements of science.

The series follows mercenary Solid Snake given government missions of finding the Metal Gear weapon, resulting in encounters with Gray Fox and Big Boss in Outer Heaven (Metal Gear) and Zanzibar Land (Metal Gear 2: Solid Snake). Later, Solid Snake meets Otacon and opposes Liquid Snake's FOXHOUND in Metal Gear Solid then assists Raiden in fighting both Solidus Snake and the Patriots in Metal Gear Solid 2: Sons of Liberty. Additionally, there are several prequel games that follow Big Boss's past and legend development as well as the origins of FOXHOUND, Outer Heaven and the Patriots.

While the original Metal Gear games had their characters designs modeled after Hollywood actors, the Metal Gear Solid games established a series of consistent designs based on Shinkawa's ideas of what would appeal to gamers. Additionally, several of the characters he designs follow Kojima and the other staff's ideas. Critical reception of the game's cast has been positive as publications praised their personalities and roles within the series.

Much as Metal Gear began as a pastiche of action movies of the time, characters were pastiches of contemporary action movie heroes. Once Yoji Shinkawa started designing the characters in PlayStation's Metal Gear Solid, they were given their respective established visual appearances. As a result of the console's limitations, Shinkawa designed them an idea that would appeal to gamers. Because of the timeskip between titles, a few of the characters have been redesigned to fit in the game's year. With the improvements from new video game consoles like the PlayStation and PlayStation 2, the staff gave the characters a more realistic look starting with Metal Gear Solid 2: Sons of Liberty although they initially had doubts about it. This brought difficulties to the staff as they had to make the faces more realistic. When illustrating characters, Shinkawa does not focus on their minor details, such as the eyes which sometimes does not try to draw, instead illustrating something more symbolic. While Solid Snake remained easy to illustrate as a result of him having a consistent design to the point Big Boss' younger self, Naked Snake, was conceived making minor changes to the original version of Solid Snake, other characters were more time-consuming owing.
