-->-- Opening narration to ''Capcom vs. SNK''

During the height of the {{fighting game}} popularity, one of Creator/{{Capcom}}'s biggest competitors was Creator/{{SNK}}, creators of the UsefulNotes/NeoGeo console and arcade system, who challenged ''Franchise/StreetFighter''[='=]s dominance with a wide array of linked and standalone games and series, culminating with their own MassiveMultiplayerCrossover, ''VideoGame/TheKingOfFighters''. Naturally, in 1999 and 2000, the [[TemptingFate inevitable]] [[VideoGame/CapcomVsWhatever happened]], and the two companies came together to both make separate fighting games based on the concept.

The fighting games of this series, so far, are these:
* ''[[VideoGame/SNKVsCapcomMatchOfTheMillennium SNK vs. Capcom: The Match of the Millennium]]''
* ''VideoGame/CapcomVsSNKMillenniumFight2000''
** ''Capcom vs. SNK Pro'' (an UpdatedRerelease that, among other things, added Dan Hibiki and Joe Higashi to the roster)
* ''VideoGame/CapcomVsSNK2MarkOfTheMillennium''
* ''VideoGame/SNKVsCapcomSVCChaos''

SNK also developed three {{Card Battle Game}}s based on the concept, the most recent for the UsefulNotes/NintendoDS ending the ''SNK'' series as a whole and notoriously containing a GameBreakingBug.
!Examples of the series in general:
* BattleIntro: The games are full of this. From the ''[=CvS=]'' duology alone do you get cool scenes like Geese throwing a Reppuken at Bison to blow his cape away.
* DemotedToExtra: Characters such as Robert Garcia, Mature, Daimon, Yang and Andy get only passing mentions, assist roles, or cameos, in the entire ''Capcom vs. SNK'' series. This is very noticeable in the SNK side, because most of the ''KOF'' teams (sans the Women Fighters Team) are incomplete in the games. For example, the Art of Fighting Team lacks Robert, the Fatal Fury Team lacks Andy, the Japan Team lacks Goro Daimon, the Villain Team lacks Billy Kane, and so on. Chang also shares his moveset with Choi in ''Capcom vs. SNK 2'', but Choi got into ''SNK vs. Capcom: SVC Chaos'' with Chang only getting cameos.
* LoadsAndLoadsOfCharacters: The ''Card Fighters'' games. Of course, being digital trading card games, the characters themselves don't appear ''per se''.
* ShoutOut: Check [[ShoutOut/CapcomVsWhatever the page]].
* SpotlightStealingSquad: The ''Street Fighter'' cast, who always make up more than half the Capcom side characters (both Capcom-published games include all 12 original World Warriors in their roster - ''SVC Chaos'' saw Zangief, Blanka and Honda miss the cut). Some of the cases would be more appropriate to call ''Street Fighter vs. SNK''. To be fair, the majority of the SNK side is comprised of characters who've already appeared in a ''King of Fighters'' game, so ''Street Fighter vs. The King of Fighters'' would be a better title[[note]]Although a good part of the ''KOF'' cast is either from ''VideoGame/FatalFury'' or from ''VideoGame/ArtOfFighting'', so there's that.[[/note]].
** The first game at the very least had Morrigan and Nakoruru, who come from series (''VideoGame/{{Darkstalkers}}'' and ''VideoGame/SamuraiShodown'') outside of both ''Street Fighter'' and ''KOF''. The second one introduced more characters from outside those games (''VideoGame/FinalFight'' and ''VideoGame/RivalSchools'' as well as other SNK participants who haven't been or had yet to be in a ''KOF'' game like [[VideoGame/FatalFury Rock]], [[VideoGame/SamuraiShodown Haohmaru]], and [[VideoGame/TheLastBlade Hibiki]]). ''SVC Chaos'' saw [[VideoGame/MetalSlug Mars People]], VideoGame/{{Athena}}, [[VideoGame/GhostsNGoblins Red Arremer]] and [[VideoGame/MegaManX Zero]] (in his ''VideoGame/MegaManZero'' incarnation) join the fray.
