Mukuro: Um... Sister? Why does the place look so... Chaotic?

Junko: Because this battle is one full of disharmony! Like Discord, the chaotic spirit of My Little Pony!

Mukuro: And Bill Cipher, the chaotic tringle of Gravity Falls.

Junko: She's Mukuro and I'm Junko and- Whoa!

*Suddenly two portals opened and two shadowy figures came through one portal and into the other before both portals closed.*

Mukuro: What was that?

Junko: Who cares?! It's time for a Death Battle!

Above the land of Equestria, a lone triangle hovered above the small town within.

Bill: Now we're takin'! So how am I gonna fill this pointless neighborhood with a little despair? Oh! How about I give them a gift?! From me to you! Ahahaha!

As he said this, he sent his Madness Bubbles all over the village of Ponies, causing all of them to start and go insane.

Meanwhile, Discord was floating around town to see what all the fuss was about.

Discord: Hmm... this isn't right. This chaos is good, but it's not mine. 

He looked up to see Bill laughing and terrorizing the town. As soon as he realized what was going on, he disappeared and teleported to Bill, eating seeds and dropping them all over the floor.

Bill: Ah, Discord! How's it been?

Discord: Great. Hey, this chaos is fine but would you mind turning it down a notch?

Bill: Why? Are you afraid cause I'm better than you?

Discord: Oh no no no. Nobody's better than Discord.

Discord tossed the seeds to the side.

Bill: Oh yeah? 

Discord: Yeah.

Bill: Oh yeah?!

Discord: Yeah!

BILL: OH YEAH?!

DISCORD: YEAH!!!

Bill: Fine then! Let's test that theory!

Bill floated up in the sky with flames in his hands.

Discord: Oh wait! Before I forget!

Discord flew down to a nearby radio that was sitting on a log. He put in a tape and pressed play.

Discord: There we go.

Bill shot a fireball at him and Discord dodged it before flying away. Bill kept shooting fireballs before firing a laser from his eye. Discord dodged the flames and made a forcefield around him that deflected the laser, causing it to fire back into Bill's eye.

Bill: Ah come on! Do you have any idea how long it takes to heal this thing?!

He grew in size and had several more arms added to him as he started rapidly punching at the forcefield. As it started to crack a little, the seeds Discord ad dropped earlier had grown into massive spikey vines, wrapping around Bill and lifting him up. Bill's eye then healed as he looked down to see an army of Discord's in roman armor aiming their bows.

Discord: Fire!

They all fired their flaming arrows as thousands of them blocked out the sun. Bill ended up making his own forcefield, cutting the vines and blocking the arrows. He then looked down to see Fluttershy, Applejack, and Rarity coming to help.

Bill: Hey! No outside help allowed!

Bill fired a beam and turned them into stone. He then created multiple clones to terrorize the town further. Discord saw this and immediately flew up at Bill, swinging his tail. Bill teleported behind Discord and hit him with a beam that sent him flying away. Discord caught himself in the air and flew at him, grabbing Bill and taking him through a portal. 

They appeared in Sonic vs Neptune as they looked around.

Neptune: Hey, this is my Death Battle! You two go!

Sonic boosted past them and ran straight at Neptune who jumped out of the way.

Bill then punched Discord through another portal and this time they ended up in Rainbow Dash vs Starscream who came out of his robotic body as a spark.

Starscream: You haven't won! I'm invincible! My Spark lives! You can never defeat Star-

Suddenly Discord crashes into the spark, accidentally crushing him as Rainbow Dash flew out of the way.

Discord: Whoops!

Rainbow Dash: Woah! Discord?!

Discord: Yep, that's me.

Discord put on a Mario cap as Bill went to punch him. Discord jumped up with the Mario sound effects to dodge the punch and stomp on Bill's head, before landing on his feet and eating some spinach. His fist grew in size as he punched Bill into another portal.

This time they ended up in Saber vs Darth Vader, where an injured Saber Alter lifted her sword ready to finish Vader off.

Saber(Alter): One more time... EX... CALI-

Bill suddenly crashed into her and sent her flying before Discord flew at him and went to jump on his head again. Bill dodged it and grabbed him by the tail, tossing him into the ceiling before throwing him down into another portal that led to Deadpool vs Pinkie Pie, where Deadpool was about to give the Death Battle Cast a piece of his mind.

Deadpool: I just got one question for you all. Just one! Why oh why, would you pull me into another one of these battles... on my birthday! Come on!

Pinkie Pie: Wait a minute! You didn't tell me it was your birthday!

Right before Pinkie Pie could grab Deadpool, Discord came crashing down to the ground with ponies above his head.

Discord: Gah... that gave me a headache...

Pinkie Pie: Discord? What are you doing here?

Discord: You know what... it's a long story.

Bill came down and unleashed a burst of electricity that destroyed the entire room. Discord quickly flew at him and grabbed him, sending him through another portal as they flew straight past Junko and Mukuro.

Junko: She's Mukuro and I'm Junko and- Woah!

they went through a final portal as Discord through him into an oversized bowl with cake mix inside. A bigger Discord took the bowl, stirred it up, put it in the oven, and made Bill Cipher Pie.

The channel changed as it was a boxing match between Bill Cipher and Discord with Bill punching Discord in the face!

It changed again to a wrestling match between Discord and Bill Cipher with Discord giving Bill an Elbow Drop! Oh Yeah!

The tv then shut off as Discord and Bill were in the Mystery Shack fighting over the remote.

Discord: Gimme that! It's my turn to watch something!

Bill: You had your turn!

Bill fired a laser out of his eye and sent Discord flying out of the building. As Discord flew into the air, the giant wooden statue came to lie and swung its axe at him. Discord quickly dodged as he grabbed the sun and stretched it out into a rope before tying the statue up with it, burning it with the heat. The statue then fell to the ground, causing the whole area to be set on fire. 

As everything burned, Bill flew up as a crack of reality was torn in the sky. Bill then grew in size once, going for a huge punch.

Discord: Ah dangit... this is gonna hurt-

The fist smashed Discord into the ground, creating a massive shockwave around him. As Bill lifted his fist, Discord ad a white flag in his hand.

Bill: Hm?

Bill turned back to normal and floated above him.

Bill: What's the big idea? You're giving up?

Discord: Ow... it looks like I'm getting too old for this. How about you call it your win and never bother me again... deal?

Discord held out his and Bill looked at it. He lit his hand on fire.

Bill: Fine... but in return...

He shook Discord's hand.

Bill: I take your mind!

Then ripped Discord's soul out of his body.

Discord: What?!

Bill opened his eyes as he looked around. It looked like he was in the Equestria within Discord's mindscape.

Bill: Hah! You fool! Now I can do whatever I- What?!

He looked up ahead to see Discord sitting down on his throne drinking the glass of chocolate milk... not drinking the milk but the glass.

Bill: Alright, what is this?! You're not supposed to be in here!

Discord: Hm? Oh, it seems I flipped your plan around a bit.

Discord turned the milk into an Uno Reverse card and tossed it in front of him. Bill looked around as the area around him started to break apart.

Discord: Instead of bringing you into my mind, I think I accidentally brought you into my own personal dimension.

Bill: What? No! Let me out of here! Let me out!

Bill raised his hand but nothing happened.

Bill: No! Why isn't this working?!

Discord: My dimension. My rules. Rule number one... 

Discord flipped a page from a rule book.

Discord: Triangles have no powers.

Bill: No... what's happening to me?! !nruter yam I taht rewop tneicna eht ekovni ot eman ruoy yas I !nrub ot emoc sah emit yM !L-T-O-L-O-X-A! DISCOOORD!!!

He reached out to him but Discord punched him and shattered him into pieces.

Discord: Ah... well that was fun. Now then...

The dimension continued to crumble as Discord made a portal back home where a colorless Twilight Sparkle was about to step on a flower wearing a purple cloak. Discord accidentally bumped into her and saved her from a raven made of shadow that nearly turned her to dust.

Twilight: What the?! Discord?! What's going on?!

Discord: Oh nothing. Just went on a little ride. 

He got up and snapped his finger, burning the flower to a crisp as Twilight's color returned.

Discord: Now if you'll excuse me, I have an appointment with Fluttershy.

He flew away, leaving Twilight Sparkle sitting there confused.

Twilight: Wait... huh?... What the-

Mukuro: Well... that happened... so what happened exactly?

Junko: Well, both these two were pretty similar in their own ways. It was clear that Bill was smarter and arguably more experienced, but while Bill is incredibly skilled at getting into the minds of others... so is Discord.

Mukuro: There was also nothing that Bill could do that Discord couldn't do either. Though Discord had a few more tricks up his sleeve. 

Junko: Right, while Bill was incredibly powerful, he still had some limitations to what he can do. Like, he can't even go into Discord's mind or take over his body unless he made a deal. And while Discord himself has his own limitations... it doesn't subtract from his own power.

Mukuro: Even if Bill did take over his mind, Discord would have complete control. He could even trick Bill into entering a clone's mind and erasing that clone. Or he can take him to an alternate dimension and erase him all together. 

Junko: Plus, Discord's power varies depending on how much chaos he is bringing and how much is happening around him. With Bill being an entity that can only bring chaos, he's pretty much making Discord stronger while he himself doesn't have the same advantage.

Mukuro: Either way, while there are variations of this fight where Bill could take the win, Discord gets it more times than not.

Discord: The winner is me!
