Originally appearing in the Battle Slave series of eroge fighting games, S first appeared in the Strip Fighter series beginning in the original Strip Fighter IV in 2008. To mostly quote a previous Strip Fighter 6 playthrough: "S is what you might call the StudioS universe's token sadomasochist - his story in-game involves defeating, humiliating, and (presumably, if the sex scenes of any Strip Fighter games are any indication) sexually assaulting fighters, with his participation in this tournament done to fulfill his (sexual) desires."
Like in later games, S is a slow but bulky fighter with a penchant for dishing out heavy damage. All three of his special moves - Knuckle Bazooka (236X), Crash Upper (623X), and Mount Punch (214X) - create a knockdown on hit, with his Crash Upper launching the opponent on hit (which are useful for juggle combos). What S specifically has in this game, however, is a forward movement option - pressing forward, down, and then down-forward (623) without pressing any buttons allows S to approach the opponent quickly, akin to the "crouch dash" movement technique in the Tekken series. S could then follow this up with a Crash Upper (done by immediately pressing any attack button), and could even link his standing heavy attack into any light attack from this technique.

We learn that S is a masochist as per his character story, and that's it. S doesn't even have much of a motivation other than wanting to sexually dominate other competitors, even when final boss Succubus shows up and decides to try out "the spirit of a male" (I assume she meant sucking off energy by raping him, or something). After defeating Succubus and seeing a sex scene in which she is tentacle-tortured (obviously not shown here), we then learn in S's ending that he has captured all his opponents after the tournament, basically being his playthings.

Beat up the Super Strip Fighter IV cast for like twenty-two minutes, and then leave. Not much else to say here.

With the crouch dash movement technique S has in this game, in addition to Crash Upper's animation resembling the Wind God Fist attack, you'd think that S was originally designed as some sort of honorary Mishima. It kinda makes playing as him in later games less fun, though.
