When Zeus appears to be kidnapping all the henchmen and sidekicks of the world, it's up to good and evil to team up to put a stop to it.  However, while OSI and the various evil Guilds team up, it's actually Henchman 21 and Shore Leave that lead the battle to stop Zeus.  Oh and it turns out Zeus was just a cardboard cutout / apparition and the original Hechman #1, now Zero, who's behind it all.  An army of freed henchmen take him down.
