While Hercule and his group were preparing for the androids. The future trio got back to their timeline and proceeded to go and clean. things up there.
Future Gohan, Trunks, and Videl arrived back to the ruins of capsule corporation. Bulma greeted them and asked them how their trip went. They explained everything that happened and how their journey went. They asked Bulma where the androids were and headed to their direction.
They got to a small city that the androids were attacking and landed in front of them. Future android 18 spoke, "well, well, well, if it isn't the tragic trio. Are you here to almost die by our hand again?" Videl spoke up, "Gohan, I'll take the blonde one, if the other gets in take care of him." Gohan acknowledged and Videl walked up. Android 18 was laughing and remarked, "This is new, you guys usually fight as a trio, now you're doing 1 on 1. It's like you want to die." Videl chuckled, "Nahhh, I just want to make this a fair fight, kaio ken times 50." With that Videl charged at 18 and delivered a vicious kick. Just like the 18 in the past did to Vegeta when she broke his arm.
This time instead future 18s arm flew off. "Ahhh shit sorry about that, looks like I overdid it." 18 was wincing in pain, "17, get in here and help." Just as he was about to get in Videl said, "just to let you know, these 2 behind me are even stronger that me. You step in and they'll shut you down for good." 18 was scared now, "how, how, did you all get so strong in such a short time?" Videl stated, "I trained all day yesterday." Android 18 stated, "You think you're funny you bitch?" Videl remarked, "Bitch I'm hilarious", with that she rushed 18 and delivered a bitch slap that and knocked her down. She then looked at her, "How about I make a game out of this like you monsters typically do, if you're still alive after 1 minute we'll tell you everything." Not even 5 seconds later, 18 was lying back in the ground, cowering, "please, spare me let us go, we're sorry." Now Videl was angry and she grabbed the android by the neck while punching her in the face and screaming at her "Is that what all those people you murdered said as well before they died by your hands you monster?" Gohan then shouted, "Finish her off already honey, we don't have time for this." With that, Videl calmed down a bit and unleashed a punch that blew 18s head off, then she unleashed a ki blast and finished off the rest of her remains. "That, was for mom."
She then looked at 17, his mouth was gaping open and he was shaking in fear, "Darling, finish off the other android, I'll go with trunks to try and help any survivors. Let's move trunks". Trunks nodded and both he and Videl flew off, 5 seconds later an explosion was heard and Gohan caught up them moments after that. "That was anticlimactic", he remarked while smirking.
A few months passed, during that time, Videl, Gohan, and trunks set about to rebuild the world. The capsule dojo was resurrected in the future and new students were bought into the school. For a few months the school was thriving, however, a few months later the trio came upon a strange sight. They walked into the dojo and saw the clothes of some of their students with the bodies missing. Some of the students crawled up to them and said weakly, "m-m-m-m-mo-mons-monster, he's still here, stop him". They went around the dojo repressing their power and found a green bug man feeding on students. Trunks rushed him and delivered a vicious beating, then he went in and cut cells limbs off to render him immobile. Trunks asked angrily, "what are you monster? Why are you doing this?" The creature was angry, "damn you boy, if you hadn't stopped me, I would have been able to gather more energy." Trunks out a sword through him and yelled, "Answer my questions before I blast you."
The bug creature answered, "I am cell, I am an Android created by Dr Gero, my mission was to merge with androids 17 and 18 in order to reach my perfect form. Although you runts ruined my plan." Trunks asked, "what were your plans monster?" The creature laughed menacingly, "my plans were to absorb enough people then overwhelm you 3, and take the time machine to merge with my past self and the androids in the past."
Trunks looked shocked, "you have a past version?" Cell answered, "as of now I'm probably in my embryonic stage in the past." Trunks then asked, "why are you answering my questions then, is it because you know you're doomed?" Cell laughed, "no, it's because of this." His limbs grew back and he popped from the floor and yelled, "Solar flare." With that, the 3 fighters were blinded and cell flew off. Trunks went after him while telling Gohan and Videl to look after the students. He flew to capsule corp, where he saw cell kill some guards and injure Bulma. Before he could enter the machine, he threw a ki blast at the machine and destroyed it, cell was mad now, but he was cornered, trunks rushed up to Cell and blasted him from existence with a Masenko.
He walked up to Bulma, "are you ok mom?" Bulma answered, "I'm ok, but the time machine is destroyed, at least you got everything you needed for Goku and Hercule." Trunks then answered, "we have another thing to worry about, this thing wanted to travel to the past and merge with the androids, and he said he most likely had a version of himself there. We need to go back and stop that thing there as well, along with helping past Goku and Hercule fight the androids, how long can it take to fix the machine?" Bulma answered, "it'll probably be around a year, I can get started right away." With that, Bulma and trunks got to cleaning up the remains of the machine and the people and started on the time machine.
