Batman, Spider-Man, Terminator and Godzilla. Release Because of copyright issues regarding certain enemy characters (many of which were based on cultural icons) there were at least four versions of the game in Japan and North America, with the later two also appearing in Europe: Software revision 1.00 (1989): Enemy characters resembling Rambo called "Rocky", Jackie Chan, The Terminator called "Hercules" in Japan and "Master Attacker" in the West, Spider-Man, Batman, and Godzilla called "Monster-G" are present. Both Spider-Man and Batman are actually fake representations of the characters conducted by a shapeshifter named "Metamorpher" who alters his appearance after sustaining a certain amount of damage. Additionally, Joe Musashi's face on the title sequence resembled that of actor Sonny Chiba dressed as his character Hattori Hanzō from the Japanese TV series Shadow Warriors (Kage no Gundan). Software revision 1.01 (1989): The fake Spider-Man is now redesigned into the licensed character from Marvel Comics. Since he is now the real Spider-Man, he does not morph into Batman. Instead, Spider-Man leaves the battle when enough damage is inflicted and Batman is replaced by a winged Devilman-like creature. Monster-G remains unmodified. The "Gunner" enemy soldiers with flamethrowers are also changed to bald men with headbands, altering their original likeness to Rambo (although Sega had the license to the character for their Rambo III console games, they did not use it for this game). Software revision 1.02 (1990): A new copyright screen is made to acknowledge the license to Spider-Man (Sega already had the license to the character for their game The Amazing Spider-Man vs. The Kingpin) and the music composition by Yuzo Koshiro. Monster-G still remains intact. Software revision 1.03 (1990): Monster-G is redesigned into a skeletal dinosaur. Everything else remains intact from the previous revision, including the licensed use of Spider-Man. This version was used in the Genesis 6-Pak cartridge along with the "Sega Classics" edition of the game. Software revision 1.04 (2009/2012): Since the licensed use of the boss Spider-Man was for a limited period of time, the game was subsequently prevented from being re-released years later. The 2009 release for the Virtual Console as well as the Xbox Live Arcade and PlayStation Network 2012 releases feature a new software revision (1.04) that omits the Marvel copyright notice and replaces Spider-Man with a pink palette swap of the character that still behaves the same as the licensed Spider-Man.
