After the celebration banquet ended, Asahi did not leave immediately because he discovered something interesting. Initially, he thought that if Goku and the others did not wander the universe, then the matter of the Super Android 17 would not occur.
However, Baby killed the scientist who created him in the universe, causing the doctor to go straight to hell. There, he met Dr. Gero, who was bent on taking revenge on the Saiyans. The two joined forces to create Super Android 17.
However, unlike in the original story where both wanted to avenge themselves against Goku and his friends, this time only Dr. Gero wanted revenge on Goku. As for the other scientist, he had already seen his target of revenge, Baby, enter hell.
Moreover, this scientist caught Baby at his weakest moment. Without the parasite ability, Baby's power was significantly reduced. The scientist brainwashed Baby, turning him into a compliant machine.
Previously, it wasn't done completely due to research, but this time, driven by hatred, Baby was thoroughly brainwashed and placed within the android they created, Android 17.
One of the two Android 17 was sent out of hell using their special technology. It must be said that these brilliant scientists were truly remarkable, as they could even temporarily open the gates of hell to send someone out.
Of course, their purpose is not just to send a person out, but to open the gate of hell completely so that they can go out. On one hand, it is for revenge, and on the other hand, it is to unleash havoc by releasing themselves from hell.
It can be said that this hell was a strange place, where the Underworld couldn't control these people, even if they were cast into hell. This hell was entirely different from the Eastern Underworld.
The local Underworld's eighteenth layer of hell was extremely miserable for the souls thrown into it. However, this hell, apart from its special environment, wasn't too terrible, and since they belonged to the dead, they wouldn't die again.
Even if killed, they would revive in a few seconds, never truly dying. This hell was practically a gathering place for super villains, resembling a prison, a very open one at that.
Asahi had nothing more to say about the design of hell, finding it far from daunting. Could this even be called hell? It could even be described as a prison with better conditions.
The most astonishing thing was that these two scientists found sufficient equipment for conducting experiments. Getting materials and making equipment in such a place was incredible.
Android 17 was sent to one of the hells by two individuals. Although Android 17 was Android 18's kin, he now lacked any semblance of rationality and could combat Super Saiyan 4. When the two Android 17 merged, they could overthrow Super Saiyan 4.
In the original work, Android 17 lost because he retained some consciousness and, after merging, exposed a flaw due to Android 18's appearance; otherwise, Super Saiyan 4 wouldn't have been a match for Super Android 17.
However, this time is different. Although Android 17 retained a bit of consciousness, Baby was also added into the mix, so the body was controlled by the brainwashed Baby, who held no emotional ties to Android 18.
Thus, Super Android 17 held nothing back. With Baby's addition, Super Android 17's strength increased, almost reaching the level of Super One-Star Dragon.
After leaving hell, under the control of the two, Android 17 first caused some havoc, catching the attention of Earthlings, before arriving at the designated location. Opening the gates of hell required one in hell and one on Earth, using identical strength to blast through the barrier before the door opened.
When waves of evil intentions struck, hell's creatures had already escaped once. This time, it was Android 17. The energy fluctuations of the two Android 17 matched perfectly, easily opening the gates of hell.
Working together, a massive vortex appeared in the sky, and another Android 17 charged out from within. As for the two scientists, they remained unrushed because they knew their exit would be pointless without first defeating their foes.
Controlling the two Android 17, they fused directly into Super Android 17, augmented by Baby's power, making him terrifying. Upon Goku and company's arrival, they realized the severity of the situation.
The moment the gates of hell opened, not only did Super Android 17 burst forth, but also former enemies like Frieza, Cell, and others poured out in succession. Fortunately, the Saiyans were no longer the same as before.
Frieza was once the first Super Boss, marking Goku's first major transformation. But now, he couldn't even defeat a child like Pan. Cell, too, had become weak, with even Piccolo able to defeat him.
However, the mass escape of the evil spirits caused some concern for Earth's people. Another formidable foe, Super Android 17, emerged.
This time, they had no Dragon Balls anymore.
The Dragon Balls disappeared after the Shadow Dragons incident. Although they could borrow Dragon Balls from Namek, they knew they couldn't make wishes lightly.
So now it can be said that their situation is quite uncomfortable. Besides, facing Super Android 17, Goku felt a headache coming on. He had previously fought a single Android 17, and in his Super Saiyan 4 state, he could barely manage. But now, with two Android 17 merged into Super Android 17, the power was overwhelming.
Additionally, he sensed Baby's rage. Having been controlled by Baby initially, he knew Baby very well. So facing Super Android 17 now, Goku felt a lack of confidence in himself. Who knew if he could win?
Even knowing it was risky, he had no choice but to fight. So, in his Super Saiyan 4 state, Goku braced himself and charged forward.
Boom!
A punch landed directly on Super Android 17, who didn't even need to dodge or defend. The punch had no effect, not even scratching the surface, failing to break through his defense.
