Chapter Notes:F-Trunks For This Chapter stands for Future Trunks.

Two Months Later

It was a bright sunny day at the Capsule Corporation's household. Outside, was none other than the two brightest scientists in the world, working on yet another invention inside the Brief family lab.

"21, is the stabilizer all ready and set yet?" Bulma asked. 21 looked up and wiped off a bit of sweat off her forehead.

"Yes, it's ready to go when you are," 21 answered. Bulma nodded and activated the machine, causing it to instantly glow as the gears went to work. In mere seconds, drops of blue liquid filled the container. Bulma clapped her hands together, happy that her invention worked.

"Great! Thanks for the help 21, it was much appreciated. Now I can produce some of this fuel for Jaco's ship in a day thanks to you," Bulma thanked.

"No problem Bulma, it's always a pleasure to work with another scientist," 21 giggled. The two had grown to be close friend due to their love of science, so far as the media seemed to call them sisters of some sort. Going on outside however, was a lavender haired boy training in the garden with the person that he looks up to like a brother. The two trained while the Pilaf-Gang hanged around to while eating lunch as they watched to two spar.

"Come on Trunks, you've got to try harder than that if you want to land a punch against me," Kuzuku teased, blocking another kick aimed at his face. Trunks landed back on his feet and was gasping for air.

"Man, can I just turn Super Saiyan at least? It'd be easier if I were to fight you in that state," Trunks complained.

"Sorry, no can do Trunks. It'd defeat the purpose if training is taken an easier route," Kuzuku chuckled. Trunks pouted before going right back at Kuzuku, throwing punches and kicks at every angle he could think of. Mai took a sip of her drink as she watched them go at it again.

"Those two sure have a lot of energy today," Mai noted.

Trunks had grown a little since their last encounter, standing at the age of ten. He's become more insistent on being strong like his father but since he was currently away with Whis again, Kuzuku steps in to fill his shoes each time 21 is asked to help out with Bulma. Kuzuku noticed that something was starting to become...off. He didn't know what but he felt a distortion in the air as he wasn't the only one. The two looked into the sky where they sensed the distortion coming, confusing their observers as to why they stopped training. Then on cue, a series of particles filled the spot before a machine appeared in the sky startling everyone. It descended to the ground, powering down as it accomplish its task. The two Saiyans flew to the glass that seemed to be covered in ashes.

"Who do you think it may be Kuzuku?" Trunks asked.

"I don't know, but considering the ash on this container, he must of went through something pretty drastic," Kuzuku muttered, wiping some of it off the get a better look. It was a man who wore a blue vest and red scarf, holding a sword on his back with blue hair similar to Bulma. Kuzuku started to examine to contraption and saw that it was a Capsule Corp model.

"Capsule Corporation?" Kuzuku muttered. He then heard footsteps fast approach them. It was Bulma and 21 who came to see what was going on as 21 sense the distortion as well. Bulma caught a glance of what the machine looked like and instantly started to worry, running faster than she thought was possible for herself to do.

"Kuzuku! Is there a boy with Blue hair in there?!" Bulma asked.

"Yeah what of it?" Kuzuku blinked twice.

"Quick! Get him out of there and bring him under the gazebo so he can rest!" Bulma commanded. Kuzuku brought the young man as well as a large book field with sticky notes that were on the floor out of the machine and laid him onto the lounge chair with a blanket covering him under the gazebo. He seemed badly injured and was breathing in and out heavily. But what was most intriguing was the fact that he looked like Trunks but older. Bulma quickly called Whis as every stood there in ignorance.

"Hello Bulma, how may I accommodate you today?" Whis greeted.

"No time, I need Vegeta and Goku back here pronto!" Bulma spoke with haste. The two Saiyans mentioned stepped forward on the staff.

"Guys, we need you to see this, look! Trunks is back and he seems pretty battle damage!" Bulma panicked.

"He's back, no way!" Goku and Vegeta said.

"Yeah so now hurry on back because we don't know what happened to him," Bulma demanded. Goku and Vegeta nodded before nudging Whis and Beerus to grabbed on. They could sense Kuzuku's energy and teleported to it with ease. It was a good thing the hero of Earth had a senzu bean, saving a trip to Korin is always a good thing. Goku ran over and gave Bulma the senzu bean for Trunks to swallow. Once he did, everyone waited for him to regain consciousness. After some time, he began to open his eyes slowly. Trunks later began to look around, wondering if he made to the past as he intended but the first sight he saw was none other than Goku who stared at him cluelessly. His face morphed into anger as he pushed the covers off quickly and charged at him, throwing a punch in hopes to get the first shot but Goku caught his arm with a perplexed expression.

"You bastard!" F-Trunks spat, leaving everyone confused. Bulma walked up to him and smacked her future son in the back of his head.

"Get a hold of yourself Trunks! You're safe so no need to fight!" Bulma scolded. Trunks blinked a few times, taking a glance at her mother with sorrowful eyes of regret. He came to a quick realization and took a look at Goku from up and down.

"Goku? I thought you were dead after the fight against Cell? Plus, I'm sorry for attacking you out of the blue like that," F-Trunks said.

"Well a lot has happened but all I can tell you is that I am one hundred percent living!" Goku chuckled with his typical goofy smile. Trunks smirked at his successful travel to the past and turned to face his father Vegeta.

"Dad...," F-Trunks whispered. While the reunion was happening, those who were unaware of what was going on were trying to dissect the situation into a more comprehensible form. Kuzuku eventually had enough and decided to ask Bulma directly rather than trying to make assumptions.

"Bulma, mine telling me exactly what's going? You call that man over there Trunks, why is that?" Kuzuku questioned.

"Oh well that's a simple question to answer. The Trunks you see now is the one from the Future. He came back to the past using a Time Machine that I've invented in the Future," Bulma answered. Everyone went into a complete dumbfound state, well everyone except 21 who was fascinated and Beerus who was a but annoyed. F-Trunks noticed Kuzuku and examined his tail freely out, taking note that he was someone unfamiliar to him.

"I'm sorry, I've never met you before so may I ask who are you?" F-Trunks said, walking up to the Saiyan.

"The names Kuzuku Ayoma, a Saiyan that landed here of Earth way back after Goku defeated Buu. I don't remember exactly what happened since I only heard stories," Kuzuku greeted.

"Well tits nice to meet you and I also couldn't help but take notice an extra unfamiliar faces as well. It's great to see that the past is looking great as ever," Trunks smiled. 21 walked up to Kuzuku giving him a unexpected hug from behind.

"Oh and this is my girlfriend, 21," Kuzuku smiled.

"21 huh, well nice to meet you," F-Trunks nodded. Vegeta had enough of the chit chat and decided to cut right into the case.

"Trunks I don't think you've come here simply for some little reunion. Tell us, why did you travel back in time again?" Vegeta scuffed. Trunks looked at him for a moment as he recalled why he was hear and grew serious. He looked down towards the ground and thought hard, recalling the memories of what had just happened.

"All I can say is that the Future is in trouble again and things have completely gone downhill," F-Trunks started.

"Is it Majin Buu?" Goku asked in which Trunks shook his head no.

"No, I've already taken care of Babidi and Dabura before they could revive him with the help of the Supreme Kai. But this threat is far worse than Buu could ever be. He arrived on Earth one day with the exact same body and face of you Goku," F-Trunks revealed.

"What!" Goku exasperated in shock.

"On that fateful day, he told this to the rebuilding population of Earth 'And now, I will annihilate the Earthlings of this planet for the sake of justice'. I went to confront him one on one in an attempt to prevent anymore deaths but he was too powerful for me to defeat on my own the first time. From then on, we were lock in constant back and forth battles for a whole year until...," F-Trunks paused and looked up with eyes that were fill with sorrowful anger.

"He managed to find our lab before we escape to even get close to the time machine, he killed mom! But before she died she sacrificed herself for me to escape by pushing me through the doors before the lab exploded! All just for me to head back to the past and come back with reinforcements!" F-Trunks yelled in frustration. Bulma walked over to her future son and patted his shoulder.

"There is no need to frustrate yourself over things. We'll head back to the past and beat that...uh what's his name?" Bulma comforted. F-Trunks stopped shivering and calmed down before going back to his serious expression. He wasn't going to lie but it felt good to let out all of that pent up emotion.

"We called him Black. But I don't think we'd be able to travel back to the past since we are out of fuel," Trunks said. Everyone was in deep thought for a moment as that was going to be a dilemma as no one knew what fuel the time machine runs on until Kuzuku remembered what he picked up, taking it out and holding it up in the air.

"I think I've found the solution to that problem. I've have time to look through this book that I found in the time machine and apparently it looks like Bulma's notes or well Future Bulma's notes. I could tell since they are mostly chicken-scratches to me," Kuzuku chuckled handing the book to Bulma before getting a glare for the comment. The Brief scientist skimmed through the book and found out that Kuzuku was indeed correct and what was even better was that these were all the plans and notes specifically for the time machine.

"What a great find Kuzuku! With this, we'll be able to go back into the past and avenge Future me!" Bulma cheered.

"Looks like I get to defeat a future evil version of Kakarrot," Vegeta smirked.

"Oh come on Vegeta you know that's not really me, just a guy that looks like me," Goku corrected.

"Hey, who said you can get a crack at him first Vegeta, what if I want a shot at him?" Kuzuku complained. The mood seemed lightened up by the Saiyan trio's competitive spirit. Kuzuku then had a thought come to mind and turned towards the F-Trunks.

"Hey Trunks, do you mind sparing one on one with me for a bit? You say that you were able to fight off this Black guy for a year so if I were to fight against you, maybe I can gauge his power," Kuzuku asked.

"Uh, sure thing," F-Trunks replied. The two walked out into the garden and stood face to face before flying high into the air. Whis and Beerus sat in lounge chair as they ate fruit to watch the fight commence. The angle lifted his staff into the air and generated a force field around the Saiyans.

"This way, the two can fight all out without holding back," Whis notified. Kuzuku nodded and waited for him to make the first move. F-Trunks didn't waste any time and charged right at Kuzuku who smirked at him. Almost instantly, the Saiyan rammed his knee into the future warrior, stopping his charge dead in his tracks before punching him hard across the face. F-Trunks stopped himself from crashing into the barrier walls and rubbed his chin.

"HAAAAAAAAAAAAAA!" F-Trunks roared, turning into a Super Saiyan 2. Kuzuku was impress at how strong he was as he charged at him once more. Kuzuku crossed his arms, blocking the barrage of punches that were coming at him, slowing backing away to regain some ground in the fight.

"Trunks sure have come a long way huh. Even Kuzuku's getting pushed back." Goku smiled as usual. Kuzuku saw a gap through his barrage and caught both of his fist and kicked him away, causing him to clutch his stomach.

"Not bad Trunks. You sure are powerful in just Super Saiyan 2," Kuzuku praised.

"Thank you but this power was nothing compared to Black. Each time I face him, he'd seem to get even more power than he was before, it was as if his strength was growing so much that he dwarfs his previous self!" F-Trunks said.

"Well if that's the case then how about I crank up the heat!" Kuzuku smirked, powering up even more until he seemingly pushed F-Trunks away with his force alone. Without even seeing him move, F-Trunks watched as he already transformed into a Super Saiyan and was above him with his fist ready. The future warrior didn't have time to block as he was punched hard in his stomach, sending him rocketing towards the ground like a cannon. Kuzuku deformed and flew down to help him up.

"Nice spar Trunks, I am impress on how strong you are," Kuzuku complemented, giving him a hand.

"Yes but...," F-Trunks mumbled as he was hoisted off the ground and onto his feet.

"Black is a whole lot more powerful than what I displayed right?" Kuzuku finished his sentence.

"Precisely and the funny thing is that he didn't even go Super Saiyan once," F-Trunks affirmed.

"Wow, then this guy is definitely no joke huh? I don't know why but I can't shake off this feeling of excitement for some reason," Kuzuku chuckled. Trunks blinked a few times and smiled at his enthusiasm

Meanwhile In The Future

The scenery was completely filled with darkness as destroyed building of once a luxurious and peaceful society years ago filled the land. People were yet to be seen as they were hiding out underground while the being known as Black ran a muck across the globe. The being was floating in the sky after the apocalyptic fire that was summoned by him dialed down. He floated there in deep thought as he recalled seeing F-Trunks in some sort of machine disappear right before his eyes and evading his Black Kamehameha. Not only just that but his Ki as well.

"Trunks where could you have possibly gone!?" Black muttered firing various Ki blasts around the debris to hopefully snuff him out of hiding. That was when he remembered that he disappeared completely from that specific spot. Black flew over to where he left and noticed that his ring was reacting to it. He motioned it forward as it let out a beam of light that began to open a rift with in the sky.

"Heheheheheh...HAHAHAHAHAHA! Trunks, you may of thought you could escape my justice through exploiting some hidden escape route but know that no matter where you hide, I will still pursue you to the end of the Earth," Black laughed, flying into the void created. As he was gone a lone figure in a blue overcoat seemed to be limping away, trying her best to make it back to her fellow comrades in one piece. She was pretty much clinging on to her strength and her hopes for F-Trunks to return back to the future with some help

Back In The Past

Kuzuku and Trunks had a little small talk before getting ready to walk back to the other until they stopped completely when they noticed something off. They weren't the only ones that caught whim of the ominous feeling and turned back towards the sky. Everything grew cloudy as a purple rift opened with raging energy all around it. The flashes of light dialed down to reveal the villain in all of his glory. His black and dark gray Gi and his appearance were indisputable.

"What is this place that Trunks escaped to?" Goku Black muttered to himself, catching a glance of his original standing by, watching him intently with a serious stare. He smirk smugly and let out a amused sound from catching on to what had happened.

"So you're Son Goku. Let me introduce myself as Goku Black, the one who will bring justice to the universe," Black claimed as the two stared off to each other.
