Marvel Super Heroes vs. Street Fighter (マーヴル・スーパーヒーローズ VS. ストリートファイター) is the fourth Marvel Comics-licensed fighting game produced by Capcom (see Marvel vs. Capcom series). It is a sequel to X-Men vs. Street Fighter which replaces most of the X-Men characters with characters from Marvel Super Heroes. In an attempt to balance the previous games' problems, the game engine was altered, although it remained aesthetically the same. The game was released for the arcade in 1997, Sega Saturn in 1998 and Sony PlayStation in 1999. 
The game uses the same tag-team format previously employed in X-Men vs. Street Fighter. In addition to all the features introduced, the player can now summon their partner to perform one of their special moves without changing their currently-controlled character.
Most of the Street Fighter characters from the previous game returned, with the exception of Cammy and Charlie, who are replaced by Dan and Sakura. However, all of the X-Men characters from the previous game, with the exception of Cyclops and Wolverine, are replaced with characters from Marvel Super Heroes, as well as Omega Red.
Like in X-Men vs. Street Fighter, the single-player mode consists of matches against other tag-teams and a two-on-one fight against Apocalypse. However, the final fight that pits the player's default character against his partner is replaced with another two-on-one match, this time against a cyborg version of Akuma. The character who deals the finishing blow to Cyber-Akuma will have their ending played.
All of the backgrounds from X-Men vs. Street Fighter returned for this game are redone in palette swap fashion.
|Blackheart||Akuma (Gouki in Japan)|
|Shuma-Gorath||M. Bison (Vega in Japan)|
- Apocalypse - Serves as a boss character and the main antagonist in the game, like he did in the previous game.
- Cyber-Akuma (Mech-Gouki in Japan): An amped up, cyborg version of Shin Akuma created by Apocalypse, to serve him as the Horseman of Death. Also serves as the game's final boss and the co-antagonist.
- U.S. Agent: Although a distinctly different character than Captain America in the Marvel universe, he is just a palette swap in the game. He has, however, his own winning quotes, which are very aggressive in comparison to Captain America's.
- Mephisto: A palette swap of Blackheart. His physical basic attacks ignite the opponent when they connect, but this is just an aesthetic difference. He is Blackheart's father in the comics.
- Armored Spider-Man: A gray version of Spider-Man that has limited armor, based on a metallic suit he wore in the comics as well as episodes later aired in the Marvel Studios animated series. He possess more resistance and sometimes no hit reaction to enemies attacks, and also jumps slightly lower than before due to the heaviness of his armor.
- Mech-Zangief: A version of Zangief that can neither block nor be put into hit stun. This version is believed to be an 'evil zombie' and also possesses a Dhalsim-style close flame. He has no hit reaction to opponent's blows, so he can interrupt combos with command throws. His moves cause increased damage and he takes reduced damage. He is very similar to Colossus.
- Sunburned Sakura: Also called "Evil Sakura", it's a tanned-skin version of Sakura who performs the Hadoken horizontally instead of diagonally, and also has Akuma's Ashura Warp and can perform the Shun Goku Satsu.
- Shadow: A darkened robotic version of Charlie with powerful super moves that have incredible start-up lag. A version of Charlie that suffered harsh experiments (brainwashing) at Bison's hands, now serves him.
- Norimaro: An original character created and owned by Japanese comedian Noritake Kinashi who represents neither Marvel nor Capcom. He appears as a regular character only in the Japanese arcade and console versions of the game, but was removed in all the overseas versions. He portrays a nerdish, cowardly schoolboy-type guy armed with a camera; who throws common school items, mini-Gouki dolls, and plushies as projectiles; and would attempt to ask for his opponent's autograph mid-battle (can be seen when the player presses the START button during a match). He uses the comical "Ultra Variety Private Memories" Super attack, which has him throwing a massive amount of school supplies and other objects.
- Just as the previous game, X-Men vs. Street Fighter, the Sega Saturn version makes use of the Sega's 4MB RAM expansion cartridge to retain the frames and the tag-team system of the original but, just like X-Men vs. Street Fighter, the Sega Saturn version was released in Japan only.
- The PlayStation port, much like X-Men vs. Street Fighter, switches from tag-team setup to a best-two-of-three round format used in the traditional Street Fighter games, due to the limited RAM of the PlayStation. Like the previous game, there's a "Crossover Mode" where the player can use a tag team of their character with their a clone of their opponent and vice-versa. For example, if the player is controlling Ken and his opponent is Spider-Man, then the player's partner will be Spider-Man and the opponent's partner will be Ken.
