Junko: I always wanted to know how it feels to have multiple personalities. I'm honestly getting bored of the one I have now just like I'm getting bored of Kokonoe.

Kokonoe: Hey! *ahem* Anyway, nobody knows how difficult it is than these two really young but incredibly powerful artificial creations.

Junko: Android 21! The New Type Android of Dragon Ball!

Kokonoe: And Jack-O, the other soul of Justice in Guilty Gear.

Junko: I'm Junko Enoshima!

Kokonoe: And I'm Kokonoe Mercury.

Junko: And it's time for a Death Battle!

In a large city, 21(good) was walking around with a bag of sweets.

21: I do hope these are good. Hmm... maybe I should try one.

21 went to reach into the bag, but before she could, Jack-O quickly grabbed the bag out of her hand. She quickly looked inside and started grabbing some for herself.

21: Hey! That's mine!

Jack-O: Wow! You have pretty good taste! Oh, by the way, are you an android named 21?

21: Hm? Yes, why?

Jack-O had a serious look on her face suddenly as she put on her mask.

Jack-O: Because I was ordered specifically by That Man... to destroy you.

21: Wait, what ma-

Before 21 could ask her question, Jack-O dashed at her and went for a punch that sent 21 flying straight into a building

21: Crud... looks like I have no choice but to fight...

Jack-O jumped up and used her Iron Pumpkin to fire multiple blasts of energy. 21 quickly summoned her shield to block the projectiles before teleporting behind Jack-O. She covered her hands in ki to make ki blades as she went to strike at Jack-O, but Jack-O's Iron Pumpkin turned into rocket boots and let her fly back to dodge it. 21 didn't give her time to breathe as she swung her other ki blade and stabbed straight through Jack-O's body. 21 then through her hard into the ground.

21: Take this!

21 fired a giant laser at her and Jack-O quickly jumped back to dodge it as her injury quickly healed.

21: Hmph.

21 flew down at her and tried to smash her into the ground, but Jack-O quickly dodged her attempt as her Iron Pumpkin turned back and fired multiple fireballs at her. 21 quickly teleported away to dodge them as she fired a giant ki blast at her. Jack-O saw this and extended her hands as she absorbed the blast into her body.

21: What?!

Jack-O: Heh, it's gonna take more than that to take me down!

21: That's- Gah!

21 quickly grabbed her head.

21: Tch! Not... now...

Jack-O quickly dashed at her and went for a kick but 21 quickly dodged it as she jumped behind her.

21: Kamehameha!

She unleashed a giant blast of energy and Jack-O quickly summoned a shield of her own to block it. 21 then dashed at her with a ki blast in her hand. Jack-O summoned a small house and threw it at her as 21 threw the ki blast, destroying the house as Jack-O dashed at 21 and hit her with an energy-infused punch that sent 21 flying back. 21 crashed through another building as she landed on her feet.

 21: Dame... too... hungry!

21 suddenly started powering up immensely. 

Jack-O: Hm?

21 started to glow. Once the light disappeared, there were two 21's. The good one was on her knees as the evil one stood in front of her laughing and already in her Majin transformation.

Jack-O: Woah, there are two of them!

21(Evil): Hahahaha! You did pretty well me, but I think it's time to let the better you have some fun!

21(Good): 21 wa-

Before the good 21 could say anything, her evil self fired a beam that turned 21(Good) into a donut. 21 then ate her other self, boosting her power greatly.

21: Ah, a tasty snack for a girl like me. Now then...

Jack-O had quickly dashed behind 21 and went for a kick, but 21 dodged it and caught Jack-O's leg with her tail before tossing her straight into a building. 21 pointed her finger at Jack-O and was charging a blast.

21: Time to get rid of this annoying nuisance.

Suddenly, three swords stabbed straight through 21's back.

21: What?!

21 turned to see three small minions with wings had stabbed her in the back. She turned to Jack-O, who had already recovered and had six more minions by her side and a holographic keyboard around her. Jack-O smiled as three of her minions charged at 21. Two of them stabbed her in the chest while the other hit her in the head with a stick and got back as Jack-O ordered all the minions around 21 to blow up. They did as it caused a humungous explosion and Jack-O smiled.

21: Celebrating early are we?

Jack-O: Hm?

Jack-O looked through the debris and saw 21's body healing from the carnage. 21 smiled as she grabbed the minion with the stick and crushed its head.

Jack-O: Grrr!

Jack-O ordered her three remaining minions to fire a giant blast of energy at 21, who looked at it with a smile and teleported above Jack-O to dodge it as she fired a giant ball of ki. Jack-O quickly absorbed her remaining minions and made a forcefield to block the blast, creating an explosion big enough to decimate the entire city. The debris cleared as Jack-O was looking up at 21, who was still smiling as she fired a bunch of ki blast down at her. Jack-O quickly flew up, dodging all the blast as she got in front of 21 and went for a kick.

Jack-O: Take this!

Jack-O went to kick her but 21 dodged it. Jack-O saw this as she went to follow up with a punch, but 21 flew back to dodge it. Jack-O quickly chased after her and went for multiple high speed punches that 21 was swiftly dodging. 21 finally caught her fist and pulled her closer to try and punch her in the face, but Jack-O saw this coming as she dodged it and tried to knee her in the face. 21 quickly let go to dodge her attempt as the two quickly flew back and stared each other down. They dashed at each other and clashed as they flew all around the already destroyed city. Each time they clashed they caused huge shockwaves that caused all the buildings to collapse. The two flew at each other one more time as they headbutted each other before rapidly going for multiple punches and kicks. 21 finally grabbed her and slammed her into the ground before firing a ki blast at her. Jack-O quickly jumped up and dodged it as 21 flew down at her and tried to grab her by the face, but Jack-O quickly kicked her away and dashed at her, and kicked her in the face hard enough to knock her out.  21 woke up as she was tied up in the middle of a grassy field.

21: What the hell? Where am I?

21 looked around and saw Jack-O being tossed up and down by her minions multiple times before tossing her all the way into space. 

Jack-O: Feast on thiiiiis!

Jack-O flew straight down to earth and hit 21 with a dropkick to the head so hard it caused an explosion that could be seen through space. Jack-O took off her mask and looked around as everything was decimated. There was lava everywhere as well.

Jack-O: Trick worked like a charm!

21: Did it now?

Jack-O turned around as pieces of 21 were coming together and reforming into her.

Jack-O: You're still alive?! Hmph... it seems I miscalculated your strength. 

21: I'm sure a lot of people did. But they all got turned into tasty treats!

Jack-O quickly dashed at Jack-O and went to try and trap her with her Iron Pumpkin, but 21 teleported behind her and fired a Hungry Beam that turned Jack-O into a donut. 21 wen to try and pick her up, but Jack-O was still in control as she went flying away as a donut.

21: Heh.

21 stretched out her tail and caught Jack-O with it. She reeled her in and grabbed her before taking a big bite out of her.

21: Mmmm mm! Sooo good! 10/10!

Junko: Well, that escalated quickly.

Kokonoe: This match was fairly even. Both these two were even in experience and intelligence, and both had similar abilities in their respective arsenal.

Junko: But Jack-O can fuse the universe with the Backyard right? The Backyard is much bigger than our universe and once she does that, she can easily beat 21.

Kokonoe: That would be true, however Jack-O's attempt takes time to accomplish, giving 21 time to kill her a million times over again. But the fact she is capable of this does prove she is capable of producing beyond universal level destruction.

Junko: Then we get to 21, who has a unique case as she made a machine that prevented Goku from using his full potential.

Kokonoe: Right. But since this is after Goku and Beerus nearly destroyed Universe 7, which is much bigger than our own universe, and Goku became that strong in his base form, it's safe to scale 21 to that as well.

Junko: So that puts 21 and Jack-O's power pretty even right?

Kokonoe: Sorta. But then you have to remember that 21 is as strong as Goku in his Super Sayian 1 transformation, making her 50x more powerful than Jack-O. And while Jack-O did have a huge strength advantage over 21, she was far too slow to keep up and could easily be overwhelmed.

Junko: One thing I can say though... this battle gave me a serious sweet tooth!

Kokonoe: The winner is Android 21

Junko: Next time on Death Battle!

Issei: Come on! Time to get this show on the road!

Tatsumi: Oh yeah?! Bring it on!
