Age 767
We begin this chapter in rocky wastelands. In the sky, there was a bright flash of light, and all of a sudden a time machine identical to the one that Trunks had originally arrived in. It slowly floated to the ground, and out of it emerged a young woman. She was 17 years old and had blue hair and black eyes. She was also wearing a blue tank top made of the same material as saiyan armor as well as pants identical to what Trunks wore when he first came to the past.
In addition to all of that, she was wearing white wristbands and purple combat boots. The mysterious woman surveyed the area and said to herself,
"Alright, I made it."
She then flew off, and a few minutes later, she landed in front of capsule corporation. She then walked up to the door and knocked on it, with Bulma being the one to answer. Surprised by the stranger at her door, Bulma asked her,
"Can I help you, miss?"
The mysterious woman breathed in and out and asked Bulma,
"Can you bring me to a man named Trunks?"
Upon hearing this, Bulma turned her head to the door and yelled,
"Trunks, there's someone here to see you!"
The future Trunks walked up to Bulma and was about to ask her why she was calling him, but he stopped as he laid eyes on the mysterious blue haired girl. After a few moments of staring, he asked her,
"Bra…is that you?"
Bulma was shocked that Trunks knew this woman, and Bra then angrily asked Trunks,
"What the hell happened to you?! You never came back, and me and mom had to fend for ourselves! The androids came and they….they killed mom….I was able to go super saiyan and got mad enough to kill them, and I've spent the last 3 years making new fuel for the time machine to come to the past…"
At this point, tears were streaming down Bra's eyes. Noticing this, Trunks put a hand on her shoulder and said,
"Sister, the reason I never came back was because God made me do so."
Trunks then explained everything that had happened since he came to the past, which shocked his sister. Trunks then finished his explanation by telling Bra,
"Do not fear, for I gave my father medicine I created for the heart virus months ago. And do not mourn our mother, for she is in a better place."
Bra was a bit unnerved by that last part and how Trunks seemingly didn't care that much that they're mother was dead, but before she could question him, she suddenly sensed a huge number of kis vanish. Trunks exclaimed,
"They're here!"
Bra was initially confused by this, but then remembered the date she had set. May 12th, age 767. This was the date that the androids attacked. Trunks yelled at her to follow him, and she did so. Both flew off and headed for Amenbo island, eventually arriving and finding that Goku, the present Trunks, Tien, and Yamcha were already there. Tien had made Chiaotzu stay behind due to the danger of the androids.
Trunks explained to Bra that he had told the Z-Fighters about the androids, and once they landed, Trunks told them,
"Everyone. This is my half-sister from my timeline. Her name is Bra and she'll help us take on the androids."
The other 4 heroes greeted Bra, and then headed down to Amenbo island. They knew they couldn't sense the androids, so they all split up to cover more ground. As Yamcha looked around, he noticed an old man alongside a fat mime and asked them,
"Hey, have you guys seen anything? I'm looking for the psychopaths who did this!"
The 2 then turned around, and Yamcha saw to his horror the red ribbon insignias on both of their hats. The old man ominously said,
"You found them."
Before Yamcha could even react, he was blasted back by a kiai from the mime, which sent him flying into an extended green arm. Yamcha coughed up blood as he was impaled on the hand, and then was grabbed on the mouth by an extending green arm and began to feel weaker and weaker.
Thankfully for Yamcha, the others then arrived, having sensed his ki rapidly dropping. Noticing them, the old man told the green man,
"Piccolo, drop him."
Piccolo Jr then did so, and Krillin quickly grabbed Yamcha and took him away to get a senzu. The rest of the Z-fighters stared down the 2 androids, and out of the shadows walked Piccolo, now having the red ribbon symbol on his gi and having unsensible ki. The old man then said to him,
"Allow me to introduce myself and my companions. I am Android 20, my rotund companion is Android 19, Piccolo's new designation is Android 22, and…"
A 4th figure then suddenly landed in front of the heroes. As the smoke from her impact cleared, the figure rose and to everyone's shock, it was Chi-Chi. Gero then finished his sentence by saying,
"This young lady is now known as Android 23."
Goku yelled,
"Chi-Chi?!"
The android narrowed her eyes and responded,
"Yes. After you left me for that bitch Bulma, Gero approached me and offered to turn me into an android so that I could get my revenge on you. The answer to the request was obvious."
Goku gritted his teeth and told the androids,
"Trunks told us all about you and how you know about our previous battles. As well as how you want revenge for me taking down you guys as kids. So let's skip the talking and get straight to it."
Goku then began powering up, Trunks and Bra doing the same. Goku's body became engulfed by fire as Trunks and Bra were engulfed with a golden aura, and after 3 huge pillars of light shot into the sky, the 3's auras cleared to reveal Goku in his super saiyan angel form, and Trunks and Bra in their super saiyan forms. In the 6 years that had passed since the defeat of Frieza, Goku and Trunks had finally learned how to access their respective forms at will.
Goku then told Trunks and Bra,
"I'll take Piccolo and Chi-Chi. Trunks, you fight the old guy. Bra, you fight the fat mime."
The 2 half blooded saiyans nodded, and in perfect sync, charged straight at the androids. Goku's first action was to fire a 2 handed ki blast to send Chi-Chi and Piccolo away. However, Piccolo somehow perfectly dodged it and charged at Goku, delivering a heavy punch that sent him flying into a building, which then collapsed on top of him. Goku burst out of the rubble with a huge burst of ki, and then charged at Piccolo head on.
However, he was then kicked in the face by Chi-Chi, who began fighting him alongside Piccolo. While Goku was stronger than the both of them, Piccolo was somehow dodging all his attacks with ease, and he kept getting hit seemingly by nothing. Meanwhile, Trunks and Bra were fighting Gero and 19 in an even battle.
The impacts from these clashes were destroying several buildings and shaking the island. Seeing this, the humans and present Trunks began doing what they came here for: Evacuating the civilians that were still alive. They knew that they couldn't do anything else, but still did their best.
As they were doing this, Trunks kneed Dr Gero in the face and unleashed an intense amount of blows onto him. The doctor was sent flying by these attacks, but as Trunks was about to land another blow, he was suddenly sent flying back by an invisible force. Confused by this, Trunks regained himself and asked,
"What was that? Was that a kiai?!"
Gero chuckled and replied,
"No. A few years ago, I discovered a strange eye near my lab. After doing some research, I found out that this eye had the ability to grant me a strange power, and it was part of a corpse spread all across the world. I had my earlier androids hunt this "Holy corpse", and I used to grant myself and many of my other androids these supernatural abilities, which I call…"
Gero then suddenly did a fabulous pose while a large, invisible mechanical figure covered in RR logos did the same behind him. The mad scientist finished his sentence by proclaiming,
"THE STAND!!!!"
Trunks's eyes widened in shock, and Gero then smugly said to him,
"As a non-stand user, you can't see the stands. I've dubbed mine "Craftsman" due to its ability to create machines from almost nothing. All I need is a scrap of metal, and I can create the ultimate fighting robot! But I won't need that power to defeat you. With all the data I collected from you, Goku, Goku's friends and even that Frieza person, YOU DON'T STAND A CHANCE!!!"
Trunks, sweating intensely, then looked at Bra and saw her being overpowered and toyed with by 19. He thought to himself,
"Lord…is this the power of your Holy Corpse?"
The half-saiyan quickly turned his attention back to Gero and yelled,
"It doesn't matter what you do!!! As long as the Lord is on my side, no enemy shall defeat me!!!"
"Hmph…We'll see about that!!!"
Trunks and Gero then charged at each other, beginning the second stage of their fight as their comrades continued to battle around them. Whoever would win these battles would determine the Earth's ultimate fate.
