Intercompany Crossover - Dc Marvel Crossover Comics

In comic books, an intercompany crossover (also called cross-company or company crossover) is a comic or series of comics where characters that are the property of one company meet those owned by another (for example, DC Comics' Superman meeting Marvel's Spider-Man, DC's Batman meeting Marvel's Wolverine. These usually occur in special "one-shot" issues or a miniseries.

Some crossovers are part of canonâ€"for example, JLA/Avengers, which has been made canon in the DC Universe â€" but most are outside of the continuity of a character's regular title or series of stories. They can be a joke or gag, a dream sequence, or even a "what if" scenario (such as DC's Elseworlds).

Marvel/DC crossovers (which are mostly non-canon) include those where the characters live in alternate universes, as well as those where they share the "same" version of Earth. Some fans have posited a separate "Crossover Earth" for these adventures. In the earliest licensed crossovers, the companies seemed to prefer shared world adventures. They took this approach to the first intercompany superhero crossover, 1976's Superman vs. the Amazing Spider-Man, and followed the same format in 1981 with Superman and Spider-Man.

Besides the two Superman/Spider-Man crossovers, a number of other DC/Marvel adventures took place on a "Crossover Earth", but later intercompany crossovers tended to present the DC and Marvel Universes as alternate realities, bridged when common foes made this desirable. (The interest in overall continuity has become a major part of even crossover comic books.)

Characters are often licensed or sold from one company to another, as with DC acquiring such characters of Fawcett Comics, Quality Comics, and Charlton Comics as the original Captain Marvel, Plastic Man and Captain Atom. In this way, heroes originally published by different companies can become part of the same fictional universe, and interactions between such characters are no longer considered intercompany crossovers.

Although a meeting between a licensed character and a wholly owned character (e.g., between Red Sonja and Spider-Man, or Ash Williams and the Marvel Zombies) is technically an intercompany crossover, comics companies rarely bill them as such. Likewise is the case when some characters in an ongoing series are owned or to some extent controlled by their creators, as with Doctor Who antagonists the Daleks, which are not owned by the UK television network the BBC although the character of The Doctor is.

Published crossovers

Golden and Silver Ages

• All Star Comics #3 (Winter 1940/1941)

The Justice Society of America was created in this issue, combining National Comics' Doctor Fate, Hour-Man (as it was then spelled), the Spectre, and the Sandman, and All-American Publications' the Atom, the Flash, Green Lantern, and Hawkman. National and All-American, separate editorial imprints, shared the unofficial "DC" label due to joint publishing and distribution.

Unofficial

• Lois Lane and Captain Marvel

"The Monkey's Paw", a story from Superman's Girl Friend, Lois Lane #42 (July 1963), featured a one-panel appearance, with his costume mis-colored, by the defunct Fawcett Comics' Captain Marvel, who was not yet a DC character. The letters page of #113 (Oct. 1971) described it as "strictly a private joke" on the part of former Captain Marvel artist Kurt Schaffenberger. The story was reprinted in #104 (Oct. 1970) with the costume coloring corrected.

• Homages

Writers during the 1960s and early 1970s sometimes engaged in a form of intercompany crossover with thinly disguised imitations of a competing company's characters, as opposed to parodies in satirical-humor stories. In this way, Marvel's superhero team the Avengers met a version of DC's Justice League of America (Squadron Sinister/Squadron Supreme) in The Avengers #70, 85-86, and 147-48. In Action Comics #351-53 (1967) DC's Superman met a villain called Zha-Vam, whose powers and name were derivative of Captain Marvel (then owned by Fawcett Comics) and of the magic word Shazam that gave Captain Marvel his powers. Superman similarly met versions of Marvel's Fantastic Four, Spider-Man and Sub-Mariner (The Kookie Quartet, Cobweb Kid, and Sub-Moron) in The Inferior Five #10 (Oct. 1968).

In the 1970s, the annual Rutland Halloween Parade in Rutland, Vermont was used as the setting of a number of superhero comic books published by both Marvel and DC Comics. Costumed parade attendees in these books were often depicted wearing the uniforms of characters from the other company. In the fall of 1972, writers Len Wein, Gerry Conway and Steve Englehart crafted a metafictional unofficial intercompany crossover spanning titles from both major comics companies. Each comic featured Englehart, Conway, and Wein, as well as Wein's first wife Glynis, interacting with Marvel or DC characters at the Rutland Halloween Parade. Beginning in Amazing Adventures #16 (by Englehart with art by Bob Brown and Frank McLaughlin), the story continued in Justice League of America #103 (by Wein, Dillin and Dick Giordano), and concluded in Thor #207 (by Conway and penciler John Buscema). As Englehart explained in 2010, "It certainly seemed like a radical concept and we knew that we had to be subtle (laughs) and each story had to stand on its own, but we really worked it out. It's really worthwhile to read those stories back to back to back â€" it didn't matter to us that one was at DC and two were at Marvel â€" I think it was us being creative, thinking what would be really cool to do." Other issues featuring the parade include Batman #237, DC Super Stars #18, Freedom Fighters #6, The Avengers # 83 and #119, and Marvel Feature # 2.

In video games

The concept of intercompany crossovers has also been explored in video games, usually in the form of having one video game company licensed out its characters to another (or vice versa).

Earlier intercompany crossovers in games occurred by taking advantage of licensing for publishing rights. GORF in 1981, produced by Midway, has the missions Astro Battles and Galaxians, which make use of characters and names from Space Invaders (Taito Corporation) and Galaxian (Namco) which at the time of the development of GORF were licenced to Midway Mfg. In 1992, Tradewest released Battletoads & Double Dragon, at that time, Tradewest owned the rights for publishing of Double Dragon by Technos Japan and Battletoads by Rare Ltd.. Rare Ltd. developed the game while Technos Japan was barely involved in the production of the game.

In 1989, DIC Entertainment produced Captain N: The Game Master, a cartoon show that featured characters and settings from Nintendo franchises and others appearing on Nintendo video game systems, possibly, taking advantage of Nintendo's licensing system to publish games. Characters such as Simon Belmont, Dracula and Alucard from Konami, Mega Man, Dr. Wily and Dr. Light from Capcom, Malkil of Wizards and Warriors from Rare and settings from Dragon Warrior/Dragon Quest, Final Fantasy (by Square Enix, independent from each other at that time), Burger Time (Data East) and Faxanadu (Hudson Soft/Falcom) appeared in the series. The 1990 animated series, The Power Team (part of the Video Power TV show) had characters from arcade games ported by Acclaim to the NES as well as games which Acclaim had publishing rights. These games were NARC, Arch Rivals (Midway), Kwirk (Atlus), Wizards & Warriors (RARE) and BigFoot (based on the famous monster truck from the game by Beam Software).

The first major intercomany crossover properly licenced is the Marvel vs. Capcom series, which originally began in 1994 with X-Men: Children of the Atom. Capcom followed this act by teaming up with rival fighting game developer SNK in 1999.

After the successful Capcom/SNK crossovers, many others have appeared since then.

Midway Games' Mortal Kombat vs. DC Universe pitted characters from Midway's Mortal Kombat video game franchise against DC Comics characters Superman, Batman, The Joker, and others. This game was produced prior to the acquisition of Midway by Warner Bros., since then, Freddy from A Nightmare on Elm Street (a WB movie) appeared in Mortal Kombat (2011) and Scorpion appeared in Injustice: God Among Us (2013). However, these can't be considered intercompany crossovers. Kratos, from Sony's God of War franchise, appeared as an exclusive in the Playstation 3 version of Mortal Kombat (2011).

The games Super Smash Bros. and PlayStation All-Stars Battle Royale were made possible by the "second party" model, in which independent developers work closely with the console maker to ensure exclusivity and quality. In both games, other third parties also appear as guest characters.
