1.1.1 Dragonball GT Episode 44: The Ultimate Android! The Two #17s Unite

The episode picks up just as Android 17 confronts Android 18 and her family (Krillin and Maron).  He wants 18 to join him in his destruction and starts to take control of her!  Krillin yells, saying she's his wife and she snaps out of it.  17 tells him she is Master Gero's creation.  Krillin tells 17 that he never called Gero "master" before and 17 starts to snap out of it but Gero's influence is too strong and 17 blasts Krillin, killing him!  18 screams and runs to Krillin and cries, remembering why she loves him.  She starts to scream and attacks 17, partly out of anger and partly to protect Maron who's terrified.  She orders Maron to run away and Maron reluctantly does so.  17 tries to blast Maron as she runs but 18 blocks the shot with her own blast but it soon overtakes her.  17 leaves the fallen 18 and Krillin but 18 isn't dead.  She crawls to Krillin, telling him she loves him and collapses.     

Meanwhile in Hell we find Goku still frozen helplessly and Cell and Freeza grinning from ear to ear.  They are planning to finally take their revenge on Goku!  They decide to use a combined attack called the Hellbuster.  Just then the ice-like spirits that froze Goku starts to fail since it can only work on the dead...but Goku still lives!  Goku charges Freeza and Cell, ready to fight!  He turns on the machine that freezes the dead and freezes the villains solid!  He marvels at how it worked and touches the newly frozen Cell and Freeza, and accidentally knocks it over...shattering them both!

Back on Earth, Gohan continues to fight several villains that have escaped Hell!  Ubu, Trunks, Goten, Pan and Gill show up and help out much to Gohan's delight.  The other Android 17, the part that was in Hell continues to fight Vegeta when the other 17 shows up along with the two doctors.  Vegeta is a bit confused and Gohan and the others arrive to hear Gero talk about the 17's joining as was intended all along.  The parts were kept separate because of the power they'd possess but now is the time it's needed.  Then the two 17's fuse...and it's a bigger, meaner, and definitely ultra-powerful 17:  Super 17!  Vegeta orders the others to attack and punches 17 in the face with all his strength...but it doesn't even affect him.  Ubu follows up, as well as Trunks and Goten...but nothing.  Gohan orders them all back and lets a Kamehameha loose...and again...NO EFFECT!  Gero orders 17 to attack and he does so, moving at speeds the others couldn't even imagine!  He hits every one of the heroes and they couldn't even defend themselves!  They all power up to SSJ and 17 laughs and powers up as well.    

Goku has been watching from Hell and tells Lord Enma to hurry and get him out so he can fight 17.  But something is blocking his power.  A force is working on both worlds and you see one of the Dragonballs starting to crack...just then Piccolo contacts Enma from Heaven and tells him to send him to Hell because he has an idea.  Enma refuses because once it has been decided on where a spirit goes, they must stay.  Piccolo starts to blow things up in Heaven which angers Enma and he sends him to Hell.  Piccolo apologizes to the Kai and disappears.

Back on Earth, Super 17 surveys the damage he caused.....all the Z fighters bashed and bloodied but not out yet.  Vegeta unleashes his newest attack, the Final Shine Attack...but it only damages the surroundings!  Super 17 cuts loose with another blast and levels them again!

Goku still watches from Hell when Piccolo appears.  Goku is surprised but happy to see him and jokes that maybe Piccolo couldn't make it in Heaven because of his scary face!  Piccolo explains he's there to get Goku out of Hell and back to Earth before the Z fighters end up dead at Super 17's hands!
