Amalgam Comics was an American comic book publisher of metafiction; it was a collaboration between Marvel Comics and DC Comics, in which the two comic book publishers merged their characters to create new ones (e.g., DC Comics' Batman and Marvel's Wolverine became the Amalgam character Dark Claw). These characters first appeared in a series of twelve comic books which were published in 1996, between issues 3 and 4 of the Marvel vs. DC miniseries. A second set (of another twelve comic books) followed a year later.

The Official Handbook of the Marvel Universe: Alternate Universes 2005 designated the Amalgam Universe as Earth-9602.

The two comic universes came together when the incarnations of their respective universes (referred to as "the Brothers") became aware of each other after aeons of slumber. To prevent the Brothers from destroying each other, characters from each universe battled to determine which universe would survive; several of the matches were determined by fan votes. Axel Asher, a character created for the event (co-owned by Marvel and DC), served as a gate keeper who became stuck while traveling between both Universes.

When the fights concluded, neither universe was willing to go. To prevent total destruction, the Spectre and the Living Tribunal created a merged universe, in which only Axel Asher and Dr. Strangefate knew the truth. Each struggled against the other to reverse or preserve the change.

Hyena (Amalgam) has not been a contender in any CBUB matches.
