In the mid-90s an unprecedented level of cooperation between DC Comics and Marvel Comics resulted in the Marvel vs. DC comic mini-series that pitted characters from both comics universes against one another before inevitably they teamed up to stop a greater threat. A highlight of the mini-series was an incident in the story that resulted in the merger of the Marvel and DC Universes. To capitalize on this the two publishers jointly released a series of one-shot comics set in this "amalgamated" universe, released under the masthead of AMALGAM COMICS. The titles were published under the conceit that there had never been a DC Comics or a Marvel Comics, just Amalgam Comics that had been printing super-hero books since the 1930s. The characters were all combinations of DC and Marvel properties - for example Super-Soldier (Superman and Captain America), Dark Claw (Batman and Wolverine) and his side-kick Sparrow (Jubilee and Robin), and teams like Judgement League Avengers (Justice League and the Avengers) and JL-X (X-Men and Justice League).

As a bit of a conceit we came up with a theoretical Amalgam Comics version of the Cavaliers, choosing to combine them with DC Comics' Justice Society. We didn't play out any of this in the game, but later on I used the relative compatibility of the Marvel and DC RPG systems to develop an Amalgam Comics Roleplaying Game.
