"If they set that Android free it will be the end of all of us. NO!"
Future Trunks

"Goku's Assassin" (すべてがおくれか!?くうころさいしゅうへい Subete ga Teokure ka!? Gokū o Korosu Saishū Heiki, lit. "Too Late to Do Anything?! The Ultimate Weapons to Kill Goku") is the ninth episode of the Androids Saga and the one hundred thirty-fourth overall episode in the uncut Dragon Ball Z series. This episode first aired in Japan on April 8, 1992. Its original American airdate was September 26, 2000.



Dr. Gero meets his end at the hands of Android 17

Vegeta blasts open the metal door leading into the lab. Dr. Gero then orders the androids to attack, but they do not follow the doctor's orders. Android 18 realizes that Android 16 has not been activated from his chamber and wants to see what he looks like. Dr. Gero tells Android 18 not to open it, but she does it anyways. Then, Android 17 begins using his Endgame technique: he punches through Dr. Gero's chest, surprising the Dragon Team, all while Gero rants about how he gave them life and can take it away if he so desires. He then decapitates Dr. Gero's head, with the latter saying that he is mad, and squashes the head beneath his sneaker, killing the scientist.


Android 16 is activated

Future Trunks then realizes that if the Red Ribbon Androids release Android 16 the world would be finished, and he blasts the laboratory to pieces using Renzoku Energy Barrage. However, Android 18 keeps the unawakened Android away from the blast. She then opens it and the Android chamber, revealing him to be humongous and have an orange Mohawk. When Android 17 and Android 18 try to talk to him, 16 does not respond. This is because Android 16 doesn't talk, unless it is about his mission. Then Android 17 tells 18 it would be time to fulfill their mission in destroying Goku. Android 16 realizes what they are doing and finally answers their questions. Then the three Androids leave.

Krillin realizes that they are going after Goku. However, Vegeta becomes angrier that the Androids have ignored him, and starts to chase them. Just before he leaves, Future Trunks tries stop him and tells him to wait for Goku. Vegeta does not listen to him and gives Future Trunks a warning punch. Vegeta then heads out of sight. After Future Trunks recovers, he along with Tien Shinhan, Piccolo, and Krillin follow Vegeta.

Meanwhile, when Gohan is still flying Bulma and Yajirobe back to their homes, Bulma tells Gohan to put them down for a couple of minutes so that she can change baby Trunks' diaper. Bulma makes Yajirobe wash one of the new diapers she carried with her in a nearby river while she plays with Trunks. Gohan then goes to her and tells her that he is ready to leave and take them home whenever they are. Realizing that Gohan really wants to get back to his own house to see Goku, Bulma rushes Yajirobe so that they take off once again.


Yamcha gives Goku some of the antidote

At Goku's House, while Chi-Chi is making dinner for Goku (in anticipation that he will wake up), Goku is in great pain. Yamcha gives Goku some of the antidote to soothe the pain, while Chi-Chi worries, hoping that Goku will pull through.

Meanwhile, Vegeta is in hot pursuit and arrives first at the battlefield to face off against the Androids. Vegeta challenges the three Androids to a match. Android 17 and Android 18 laugh at Vegeta's request and call him too big for his boots. After a few words are exchanged, 17 and 18 ask 16 to fight Vegeta. He refuses since Vegeta is not Goku and isn't part of his mission. 18 then agrees to do battle against the Saiyan Prince.

Bruce Faulconer tracks[]

  • "Vegeta's Theme" - When Vegeta suspects that Android 17 and Android 18 are the Androids Future Trunks predicted after breaking down the door of Dr. Gero's lab.
  • "Frieza's Revival" - When Android 18 checks Android 16's pod against Dr. Gero's orders.
  • "Ginyu Transformation" - When Android 17 kicks off Android 20's head and smashes it.
  • "Ginyu Transformation" - When Future Trunks attempts to destroy Android 16 before he is activated.
  • "Vegeta's Theme" - When Vegeta decides to track down Android 17 and Android 18 himself and calls them cowards.
  • "Vegeta's Theme" - When, after turning into a Super Saiyan, Vegeta sarcastically says the Z Fighters can wait for Goku and orders Future Trunks to get out of the way.

Differences from the manga[]

  • Yajirobe washing his undergarment in a river after Trunks urinates on it is exclusive to the anime.
  • Chi-Chi cooking a meal for Goku for when he wakes up and his continued struggle with the virus in the other room is exclusive to the anime.
  • Android 17 in the manga merely assumes Android 16 was weaker than him. The anime has him go the extra mile by utilizing a similar ability to 3D Scan Mode to analyze his power level before awakening him before confirming he was weaker.


  • When Yamcha tells Chi-Chi that they too should take some of the heart medicine, Chi-Chi asks Yamcha to buy his own, though the heart medicine they are taking is from the future and has not even been made in their time yet. This is only in the English dub. In the original Japanese, Chi-Chi asks Yamcha what Gohan has been doing and Yamcha lies that perhaps he's out playing somewhere. This conflicts with Chi-Chi seeing Gohan, Goku, and Piccolo off at the end of "Goku's Ordeal", as she knew full-well that her son went out to combat the Androids. Surprisingly, this was also in the manga.
  • Android 16 makes his debut in this episode.
  • Android 17 and 18's rebellion and murder of Dr. Gero was reused for the opening scene for Dragon Ball Z: Super Android 13!, although the only differences are that none of the Z Fighters were there to witness Gero's death, and Gero's speech before being killed was completely different between the movie and the episode, at least in the English dub.
  • In Japanese, #17 asks #16 if he was built from a male human base, only for the latter to correct him by saying he is fully artificial. The dub has #17 ask #16 if he's on board with taking a car to Goku's house only for the latter to ask, "What? Did you just say 'Goku?'" #17 muses to himself that #16 isn't made from a human base without the latter confirming it.
