It's New Years Eve and CRONUS escapes from Tartarus! When he learns of the PROPHECY, Cronus frees the GIANTS and unleashes the fearsome TYPHOEUS in order to stop JAY, HERRY and ATLANTA from discovering their destiny.

Who let the dogs out? CERBERUS did! What in HADES can calm this savage beast? Only ORPHEUS' lyre can do that; problem is the heroes have to travel to the UNDERWORLD to get it... and that's exactly what CRONUS wants them to do.

After NEIL single-handedly captures MEDUSA, he can't stop bragging to the gang. Neil not only drives them crazy, but he also gets under Medusa's sisters scaly skin. When the GORGONS kidnap Neil in exchange for Medusa, the whole team is caught between a rock and a hard place.

When CRONUS manages to slip some ancient DNA into a cloning experiment, the heroes have to grab the bull by the horns as MINOTAURS run loose in New Olympia's underground tunnel system. To defeat them though, Odie has to get over his claustrophobia and help the others out of a tight spot.

CRONUS awakens a descendent of MEDEA, and JAY feels the fury of a witch his ancestor Jason once scorned. Of course Medea isn't alone, she has an army of AMAZONS covering her back. Hopefully Jay will realize in time he has an army of his own in his back pocket: SPARTOI WARRIORS.

ARCHIE'S curiosity gets the better of him and he opens PANDORA'S BOX, unleashing a horrible PLAGUE and little HOPE. But when Atlanta, Odie and Herry are infected and the plague threatens the city's water supply, it's Archie's ancestry that provides the only ray of hope.

The heroes have to keep their head above water when CRONUS frees the KRAKEN. But this isn't just another terrible beast he's summoned to defeat the heroes- it's bait to draw out POSEIDON so Cronus can exact revenge! Problem is: his plan works!

The CYCLOPS that was blinded by Odysseus is understandably bitter after all these years. CRONUS offers the Cyclops his sight so he can exact his revenge upon the heroes- and when Jay and Odie are captured, it's nothing but trouble as far as the eye can see!

Jay is poisoned by a Chimera when trying to save Odie, and the other heroes only have a short period of time to bring back aconite from the Underworld's Plains of Asphodel to save him before his soul is lost to Hades forever and the prophecy is broken. Meanwhile, Jay has to elude and fight Atropos, one of the Fates whose duty is to take his soul to rest eternally in the Elysian Fields. With the end of the world coming if the heroes fail, Cronus also attempts to put together an ideal costume for his reign.

Neil's been kidnapped! Kidnapped! Kidnapped! ECHO steals away Neil, descendent of her long time love Narcissus, and leaves the heroes at CRONUS' mercy. Surprisingly, Neil has some sound advice for Echo and manages to save his friends.

It's New Year's Eve and CRONUS' powers are at their peak! Though he sure puts a damper on the heroes' party by killing Odie, Jay finds a way to go back in time and save their friend. Not to be outdone, Cronus goes all the way back to the TITAN WAR for another shot at defeating ZEUS!
