 * Ragna the Bloodedge (DLC costumes in Dead or Alive 5 Last Round)
 * Sonic the Hedgehog (crossed paths with Capcom characters in the comics/Super Smash Bros. series and Pocket Adventure was published for Neo Geo Pocket Color, besides SEGA having close partnerships like Monster Hunter collabs in MH4 Ultimate/Rise/Frontiers, few published games on their consoles/Atomiswave board, etc.)

Mechanics/Grooves

 * Shared Mechanics
 * Run/Dash & Back Hop (used in SNK's games since Art of Fighting/Samurai Shodown and Capcom implemented the mechanic since Street Fighter III)
 * Short Hops
 * Super Jump (used in SF III and IV through Crimson Viper/Ibuki by Capcom's case)
 * Capcom - Same as Street Fighter 6 ' s Drive System, which consists of various mechanics from the previous installments/titles below. Allows for supers (as Super Arts) besides a traditional six-button layout (SNK characters' close normals being turned into additional/proximity normals or command moves like Krohnen's close C/heavy punch as his standing Fierce/Hard Punch).
 * Alpha/Zero - Drive Reversal (Alpha Counter)
 * Third Strike - Overdrive (EX), Drive Parry
 * Street Fighter IV - Drive Impact (Focus Attack), Drive Rush (Focus Attack Dash Cancel)
 * SNK - Same as The King of Fighters XV in a six-button layout, with extra buttons being used for both the Emergency Evasion (A+B/light attacks) and Blowback (C+D/heavy attacks). Capable of using the MAX Mode with up to three bars of supers (as Super Special Moves) and EX moves, with a Guard gauge replacing the Drive Gauge (with Capcom characters' proximity normals being used like Ryu's Short Uppercut/Back+Heavy Punch in SF6 as his close C/Heavy Punch).
 * Guard Cancel Blowback (Drive Reversal)
 * Rolling (Drive Parry)
 * Shatter Strike (Focus Attack)

Other Stuff

 * Street Fighter 6 ' s Eternity and The King of Fighters XIV & XV ' s Clemence Bellamy will appear as co-hosts/commentators for News Combo 7 (which returns from Millennium Fight 2000 alongside it's female host) in the arcade mode's cutscenes.
 * TBD
