Following the final battle with Baby, all of humanity was returned to Earth with a final wish. As things return to normal, it's time once again for the World Martial Ares Tournament. But this contest proves to be a test for all as Goku and Pan fight in the wrong divisions, a plan to fix the figure is unearthed and an old ally returns to battle Goku one last time!

In the depths of Hell, an evil union between Dr. Gero and Dr. Myuu takes place. Soon after, Trunks is ambushed by Android 17 as a warning to Goku... Come to Hell or Earth will be attacked! As Goku travels to Hell to meet an uncertain fate, a fleet of ancient enemies flood the earth on a mad rampage!

Cell and Frieza are back! After getting trapped in Hell, Goku must confront and defeat the villains if he is to return to Earth. But things get sticky when he falls in the deepest, darkest realm of Hell, where he must endure tests that would drive an ordinary person to madness!

With Goku fighting for his life in Hell, the heroes of Earth are having troubles of their own... the two No. 17s have merged! Super 17 is the ultimate artificial killing machine... something that Goku's closest friend tragically learns first-hand!

Super 17's destructive power reaches new heights as the Z-Fighters are left battered and broken at the android's feet. Vegeta knows he must make a stand or all hope will be lost. But Piccolo has a plan to free Goku from his other worldly prison.

Goku's attacks are useless against Super 17! Knowing Goku's abilities first-hand, Dr. Myuu programmed Super 17 to predict Goku's techniques and attacks.... and the ability to transfer the attacks into fuel for the android killer! As each moment passes, Super 17 gets stronger... and Goku gets closer to his demise!

While Goku is preparing for the end, help comes from an unlikely source. It is Android 18, and she is mad! Determined to avenge the death of her beloved, No. 18 unleashes her full fury upon her android brother. As everyone watches in disbelief, they are unaware that the most dangerous power of all time is about to be awakened!
