During the height of the fighting game popularity, one of Capcom's biggest competitors was SNK, creators of the Neo Geo console and arcade system, who challenged Street Fighter's dominance with a wide array of linked and standalone games and series, culminating with their own Massive Multiplayer Crossover, The King of Fighters. Naturally, in 1999 and 2000, the inevitable 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:
- SNK vs. Capcom: The Match of the Millennium
- Capcom vs. SNK: Millennium Fight 2000
- Capcom vs. SNK Pro (an Updated Re-release that, among other things, added Dan Hibiki and Joe Higashi to the roster)
- Capcom vs. SNK 2: Mark of the Millennium 2001 (also known as Capcom vs. SNK 2: Millionaire Fighting 2001)
- SNK vs. Capcom: SVC Chaos
SNK also developed three Card Battle Games based on the concept (the Card Fighters Clash series), the most recent for the Nintendo DS ending the SNK series as a whole and notoriously containing a Game-Breaking Bug.
While no direct sequels were made to any of the games here since the late 2000's, Capcom and SNK characters went on to have Guest Fighter appearances in other games:
- Tekken 7: While not part of the game at launch, Akuma and Geese joined the roster through updates, both bringing modified versions of their 2D move lists with system mechanics based on Street Fighter IV and The King of Fighters XIV.
- Granblue Fantasy: As part of two collaboration events, characters from Street Fighter and Samurai Shodown can join the player's collection of heroes; Ryu, Chun-Li, Haohmaru and Nakoruru can be recruited via this method.
- Super Smash Bros. Ultimate: Ken (as part of the launch roster) and Terry (via DLC) join the Smash Bros. series in this installment of Nintendo's premier Massive Multiplayer Crossover, joining Ryu & Mega Man - veteran fighters with one appearance each to their names.
Examples of the series in general:
- Battle Intro: 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.
- Demoted to Extra: 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.
- Irony: The SNK-side art for both Capcom vs. SNK games is done by famed SNK artist Shinkiro. However by that point SNK had gone under and Shinkiro was working as an artist for Capcom (with the original game being one his first major projects for the company, no less).
- Loads and Loads of Characters: The Card Fighters Clash games. Of course, being digital trading card games, the characters themselves don't appear per se.
- Shout-Out: Check the page.
- Spotlight-Stealing Squad: 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 titlenote .
- The first game at the very least had Morrigan and Nakoruru, who come from series (Darkstalkers and Samurai Shodown) outside of both Street Fighter and KOF. The second one introduced more characters from outside those games (Final Fight and Rival Schools as well as other SNK participants who haven't been or had yet to be in a KOF game like Rock, Haohmaru, and Hibiki). SVC Chaos saw Mars People, Athena, Red Arremer and Zero (in his Mega Man Zero incarnation) join the fray.
