Ruby, Trunks, and Krillin arrived at the remains of Gero's Lab.

Ruby: So, according to what Cell said, Gero's Computer is below the lab.

Krillin: So, do we just blast a hole or-

Trunks: HA!!

Trunks cut it open with his sword.

Ruby: Wow.

Trunks: Uh ... Aunt Ruby?

Ruby: You're as cool as your Dad.

Trunks: (blushing) Th-Thanks.

Ruby: Okay, now let's go!

The three of them head below.

Trunks: If we run into more Androids, don't tell Vegeta.

Ruby: Definitely not.

Krillin: I swear to God. Unless ... he threatens me of course.

Ruby: And then I'll have (Y/N) punch him in the stomach.

The trio kept walking as they saw a massive machine before them, which seemed to be off.

Ruby: This is Gero's Computer?

Trunks: A left over of his sick mind.

Ruby: How could he do this to 17 and 18. They ... didn't deserve it.

Trunks: You still think they won't turn evil?

Ruby: I sensed it. Those two, their hatred wasn't for humanity. It was for Gero.

Krillin: Guys, I think this is Cell.

Krillin pointed to a small creature in a tank.

Ruby: This little thing ... in the future he will become a demonic beast.

Trunks also found some blueprints.

Trunks: These are the blueprints of 17 and 18!

Ruby: Really? Hey, Blake was right, they were human! Their real names are Lapis and Lazuli. And-

She saw data on 16.

Ruby: 16 WAS DESIGNED AFTER GERO'S SON?! What do you know, he did have a heart underneath all of his evil.

Trunks: We have to get this to my Mom once we get out of here!

Ruby: You sure about this?

Trunks: We can't take any chances if Cell is about to absorb them.

Ruby: But, they still- I guess you're right.

Krillin: Wait, you mean in blow them up?!

Ruby: Yeah, the Androids had bombs placed in their bodies, in case they would rebel. So-

She thought of 17 and 18 being destroyed.

Ruby: I don't want them to die, but ... sometimes ... we have to make the hard decision.

Krillin: But ... 18.

Krillin couldn't stop thinking about the kiss that 18 gave him.

Ruby: You like her, don't you Krillin?

Krillin: (blushing) Y-Yeah.

Ruby: I'm sorry.

Trunks: I hate to interrupt the moment, but we don't have time to waste!

Ruby: Right!

The three charged up their chi, and unleashed energy attacks onto the lab, destroying it!

Just outside...

York was seen with three capsules.

Watts: York, did you retrieve everything?

York: Yes. I have the AI of the computer. I figured they would destroy Gero's work, but I saved it all. His mind, and his last 3 Androids.

The capsules had 13, 14, and 15 on them.

Watts: Good work. Also, what about the other two doctors?

York: I'll do my best to find them.

Watts: Good. The more geniuses we have in Neo MADS, the better.

York: Right. Once Cell is destroyed, I'll make sure that the Dragonballs haven't been used after a whole year. Then I'll raise the lab!

Watts: Good. How do you know that-

York: Piccolo may have changed, but there are more Namekians out there. There will be a new Guardian of Earth. I'm sure of it.

Back with the heroes...

You all regrouped with you bro shaking with Goku.

(Y/N): Glad to see you back on your feet, Buddy!

Goku: I know all about that's happened.

(Y/N): I'm sorry Goku, we-

Goku: It's alright. You did what you could (Y/N).

You both then faced Vegeta.

(Y/N): Vegeta's shut down. He's avoided training; and even talking. He just stands there.

Goku: He just needs a push in the right direction. Vegeta!

Vegeta: What do you want Kakarot?

Goku: Come on, you know what they say, when you fall off that horse, you get back up and eat that horse!

Vegeta: WHAT?!

Goku: What if I told you that there's a room where a whole year of training in there lasts one day outside?

Vegeta: (shocked) Seriously?!

Goku: Yeah, but it's only fit for a few people at a time.

(Y/N): I'll allow a special use for you to come in. That way we can spar as much as we want.

Vegeta:

[There should be a GIF or video here. Update the app now to see it.]

(Y/N): Nice! It's known as the-

At Kami's Lookout...

Popo: Hyperbolic Time Chamber.

Vegeta:

[There should be a GIF or video here. Update the app now to see it.]

Ruby: Honestly, we're not even sure about what he really is either.

Popo: Okay Maggots, three of you will go in. Best of luck.

(Y/N): You ready Trunks?

Trunks: Uh ... yeah.

He smiled a bit.

Blake: It's actually really sweet how much Trunks wants to train with his father.

Yang: Yeah, but is letting Vegeta join a good idea?

Weiss: (Y/N) can keep the asshole under control after all.

(Y/N): Here we go then!

You entered with Trunks and Vegeta.

And then Everyone else sensed-

Goku: That energy.

Yang: It's-

Ruby: Cell! HE'S GOING FOR 17 AND 18!!! COME ON!

Meanwhile...

The Android trio saw Cell before them.

17: WHAT THE HELL IS THAT?!

Cell: Hello Brother and Sister.

18: EXCUSE ME?!

Cell: 17, 18, the day has finally come where you two will come inside of me, and help me reach perfection!

18: WHAT?!

16: I don't know who you are, but I won't allow you to do that.

Cell: And who are you?

16: I am designated as Android 16. I can tell just by looking at you, that you are a being who should not have existed.

Cell: Funny, I get that from pretty much everyone else. Just because I look like a bug doesn't mean that I don't have some standards.

17: Okay, you are just creepy! GET LOST YOU DAMN BU-

But as 17 attacked-

Cell. DETROIT SMASH!!

Cell greatly damaged 17, causing him to fall to the ground in intense pain!

17: Wh-What?!

Cell: SUNLIGHT YELLOW OVERDRIVE!!

His Hamon Attack, drained 17 of any strength!

18: 17!!

As 18 went to defend her brother, Cell grabbed her by the hair and smashed her into the ground!

As he continued to overpower them-

16: STOP IT!!

16 punches Cell in the face.

17: 16, what are you-

16: It was nice knowing you both. I had a good time. Farewell, my friends.

18: NO!! 16!!!

16 and Cell started to fight with Cell trying to take his energy, but 16 smirked.

Cell: WHAT?!

16: One thing I can thank my creator for, is that I'm completely mechanical. So you cannot absorb energy from me.

He punched Cell so hard, he coughed up blood!

Cell: ARGH!! GOD D- AAAAAAAARGH!!

16 ripped off Cell's tail!

16: Now you cannot absorb them.

Cell: Tough luck.

He regenerated his tail!

16: I suppose I have no other choice. I must take another life.

He fired his fists right at Cell!

And then he smashed him into the ground!

16: INFERNO BLAST!!

16 blasted Cell over and over, until he was gone!

17: 16 ...

18: I didn't think he was- 17!!

Cell appeared and-

Cell: WHITE DRAGON: SOLAR FLARE!!!

Using Dragon Slayer Magic, Cell unleashed a super powerful Solar Flare, blinding everyone!

Everyone: AAAAARGH!!

And then-

17: NOOOOOOO!

He absorbed 17!!!

16 and 18: 17!!/BROTHER!!!

Cell: HAHAHAHAHAHAHAHAHAHAHAHA!! YES!! YES!! THE POWER!!! HAAAAAAAAAAA!!

As Team RWBY arrived, they saw Cell transform.

???: Ah, Ruby, you've come back with your friend, girlfriend, and sister. Good. Let's see how much stronger I've become.
