Frieza and King Cold stared at the person before them. 

Frieza: And what are you going to do about it Monkey? 

???: You can't fool me Frieza. 

Frieza: Oh, so you do know my name. I guess you're a lot smarter than the average monkey. Kill him. 

One of his minions went forward. 

Frieza Minion: Right away Lord Frieza. 

He checked the scouter. 

Frieza Minion: Power Level of 5? Shit ain't nobody got time for that. 

He fried a laser gun at the man, but he defected it and took him down with- 

???: DETROIT SMASH! 

Frieza: What? 

The others charged at him, and- 

???: AVAN STRASH! 

He cut them down easily. 

(Y/N): This ... Chi ... it's ... like mine. 

Ruby: What's going on over there? 

Frieza: For a Monkey from Earth, you're really good. 

???: Now for you. 

King Cold: You're going to kill us? 

???: Yeah, in a few seconds. I'm as strong as (Y/N) (L/N) and I don't show mercy all the time like Son Goku. 

Frieza: Oh, you're a friend of the two Super Saiyans? 

???: No, I have never met them, I just know them. But you should know, I'm a Super Saiyan too. 

And then he powered up into Super Saiyan! 

(Y/N): AGH! It's the Chi of when I was a Super Saiyan! 

Frieza: YOU! THOSE EYES! THEY- 

He saw you in them. 

Frieza: NO! NO! KILL! MURDER! DESTROY! EXTERMINATE! EXTERMINATE! 

He tried to blast the man, but he dodged and then fired-

???: KA ... ME ... HA ... ME ... HAAAAAAAAAAAAAAAA!

Frieza and King Cold jumped out of the way only for the stranger to charge in and- 

???: ITTORYU: LION SONG! 

And then he sliced Frieza in half! 

And the he cut him up into more pieces, and blasted him! 

(Y/N): WHOA! HOLY CRAP! THIS GUY TOOK DOWN FRIEZA EASILY! 

Vegeta: WHAT?! 

(Y/N): AND HE'S SUPER SAIYAN TOO! 

Vegeta: Y-You don't know that! He could be Super Human! Ever think of that? 

Yang: Says the Not Super Saiyan. 

Vegeta: FUCK OFF BLONDIE! 

Blake: Why do you keep doing that Yang? You realize he could- 

Yang: It's a game. If he gives in, I win. And he knows that. 

Back with the Stranger... 

King Cold: YOU- YOU! YOU KILLED MY SON! AAAAAAAAAAAAAAAAAARGH! 

But he caught King Cold's attack. 

King Cold: ARGH! WAIT! I'll give you two p- 

He then punched him in the stomach and ripped out his heart! 

???: Swallow. 

He ripped out the bastard's jaw, and shoved the heart into it, and then- 

(Y/N): HOLY CRAP! HE'S DOING WHAT I DID TO TAMBOURINE! 

He crushed King Cold's head. 

And then he blew up the ship. 

(Y/N): HEY! Are you really- 

???: Holy crap. That's ... Dad! Uh ... hey, I'm here to greet Goku. Want to join? 

(Y/N): What's your name? 

Trunks: Trunks. 

(Y/N): Are you sure he's coming? 

Trunks: Yeah. Come on. 

You motioned everyone over as Trunks threw a Capsule that brought out a mini fridge. 

Weiss: Wow, getting a good look at the guy now, you know (Y/N), he looks kind of like you. 

(Y/N): R-Really? 

Ruby: Hey yeah! He has your eyes! 

Yang: And is that the Demon Dragon Balde? 

Trunks: We have three hours left. Any one want a Hetap? 

(Y/N): ME! 

Bulma: Sure, I can go for some. Wait that jacket is from Capsule Corp.

Trunks: Yeah, that's Mom alright. Y-Yeah. It is. 

(Y/N): How do you know Goku's going to be here soon? 

Vegeta: He is right. Who the hell are you? 

Trunks: That's classified. 

Vegeta: WHAT?! 

He grabbed him by the collar. 

Vegeta: KAKAROT, HIS SPAWN AND I ARE THE ONLY SAIYANS LEFT! 

(Y/N): Technically Gohan is Half-Saiyan so- 

Vegeta: I DON'T CARE (L/N)! KEEP IT TO YOU- 

You punched Vegeta in the gut. 

Vegeta: AGH! 

(Y/N): Sorry about Vegeta, he's an asshole. 

Trunks: Yeah, they both mentioned that Uncle Vegeta was like that. 

(Y/N): How can you tell he's not a Saiyan? 

Vegeta: Because ... most Saiyans have black hair. 

After a while... 

Trunks: He's here. 

(Y/N): Yep. I sense him. 

Down came a Ginyu Force Pod and- 

???: Huh? Guys? How did you know I was here? 

Goku came out in a strange outfit. 

Krillin: HEY IT IS GOKU! 

Gohan: DAD! 

Goku: How did you guys know I would be here? 

(Y/N): This guy. He just knows you. He even took down Frieza. And he turned Super Saiyan. 

Goku: WOAH! Really? He looks so young! 

Trunks: Do you think we can talk Goku? 

Goku: Sure. 

And so... 

Trunks: Alright, the reason why I can turn Super Saiyan is because I'm (Y/N)'s son. 

Goku: WHAT?! YOU'RE (Y/N)'S SON?! Are you serious? 

Trunks: Of course. I wouldn't joke about this. 

He looked at him. 

Goku: Yeah, you definitely have his eyes. I can see the resemblance. 

Trunks: I will be born 2 and a half years from now. But I didn't use the time machine just for that. There's more you have to know. Three years from now on May 12 around 10 AM, a dangerous duo will attack South City. 

Goku: Who are they? 

Trunks: Androids. They were created by Dr. Gero, a scientist of the Red Ribbon Army. 

Goku: WAIT! RED RIBBON ARMY?! That's the same army, (Y/N), Ruby, Weiss, Blake, Yang, and I took down when I was still a kid! 

Goku recalled a lot of memories such as getting shot down by Colonel Silver, the battles inside of Muscle Tower, meeting Eighter, going to Penguin Village where General Blue was beaten by Arale, saving Upa from Captain Yellow, the fights with Tao, and defeating Officer Black! 

Trunks: It's true. The army was defeated, but Gero escaped to plot his revenge. He created two Androids called 17 and 18. 17 killed him and then he and his partner began to destroy mankind! 

Goku: These two scare you? 

Trunks: They never run out of energy, and they're unstoppable. Compared to Frieza, they're even more demonic. 

Goku: And you didn't have help? 

Trunks: I'm the last fighter. My Father, he was critically injured during the battle, and is on life support. Ruby lost one of her eyes and wears an eyepatch, Weiss' sword got destroyed, Blake was crippled, Yang lost an arm. And they were lucky. Vegeta, Krillin, Yamcha, Tien, Chiaotzu, and Piccolo were all murdered in the battle. Gohan escaped and Dad entrusted him to be my mentor. However, sixteen years from now, he was killed. 

He then remembered a horrible moment.

Goku: Trunks? 

Trunks: Huh? Yeah? 

Goku: What happened to me? 

Trunks: You died of a heart virus before the battle. Not even Senzu Beans worked. 

Goku: Aw man. 

Trunks: Luckily, I have some medicine to help you out. 

Goku: AWESOME! What flavor is it? 

Trunks: Bacon Flavor. 

Goku: HAHAHAHA! NICE! 

Trunks: My Mom made it myself. 

Goku: Oh really? Who is she? 

Trunks: (blushing) B-Bulma. 

Goku: WHAT?! BULMA'S YOUR MOTHER!? 

(Y/N): Huh? 

Bulma: Did they say my name? 

Goku: Wow, (Y/N) and Bulma. They've been dating since the day I met them, but I didn't think that they would have a son as strong as you. 

Trunks: Yeah. They didn't marry yet. They made a vow to get married when (Y/N) gets into his late to mid 20's. 

Goku: I don't believe it. 

Trunks: I never saw my Dad so young before. But looking at him now, I can see what a great man he is. Just promise me you won't tell them, okay? 

Goku: Sure. I promise. Thanks. 

Trunks: No problem. 

Goku: I'll tell them everything about what will happen, okay? 

Trunks: Thanks! 

He then took off. 

And so... 

(Y/N): So, Trunks said something about Androids coming in three years? 

Ruby: We've got a lot to train then! 

(Y/N): I'm just glad you survived! 

Goku: Oh yeah, (Y/N), I got something to teach you. I think you'll love this! 

A few minutes later... 

Goku had crash-landed on a planet named Yardrat while he was away, and they helped him, and taught him a technique called Instant Transmission, and boy you knew it was going to be useful! 

Ruby: So, Androids in three years. 

Blake: That's going to be a lot to take in. 

Yang: But what about... her? 

(Y/N): Chichi? Oh boy. Let's go. 

At Goku's House... 

Chichi: HELL NO! 

(Y/N): I knew it. 

Goku: Come on Chichi, please? 

Chichi: WHY SHOULD I LET OUR POOR LITTLE BOY GO OFF TO TRAIN WHEN HE CAN JUST HAVE A NORMAL LIFE?! IS IT SO WRONG OF ME TO- 

Goku: Chichi, just relax. There's no need to- 

But as Goku pat Chichi on the back- 

Chichi: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

She flew out of the house and hit a rock head first! 

(Y/N): HOLY CRAP! 

Goku: CHICHI! OH MY GOSH! I'M SO SORRY! 

Gohan: Is ... Mom going to be okay? 

(Y/N): Eh, she'll be fine. 

Later... 

Goku: I'm really sorry Chichi. 

Chichi was all bandaged up and in bed. 

Chichi: Ugh, go on, take him. I know I can't complain against you. 

(Y/N): Heh. Those two crazy kids make it work alright.
