Hey, everyone! Here is the start of Ben 10 meets DC Superhero Girls season 3! Let's begin!

NOTE, THESE ARE MY OWN STORIES! I DON'T OWN ANYONE IN THIS SERIES! Except for the new Miraculous, it's mine.*

Ben: [narriating] Metropolis, my former home. This is where my new friends and team save their home. This includes Diana Prince, the Wonder Woman, Barbara Gordan, Batgirl, Karen Beecher, Bumblebee, Jessica Cruz, Green Lantern, Zee Zatara, Zatanna, and my girlfriend, Kara Danvers, Supergirl, the Kryptonian Sayian form that is really strong with a really strong heart. There are others too, and their all brave and amazing people. It's been a year since our victory with Lex and Azure team of villains. And with no other threats in the way, we can go back with our normal lives.

While that audio was playing, a certain animal mutanting scientist that was just a head in a jar with crab legs was listening to it, this was Aloysius Animo, or Dr. Animo!

Dr. Animo: That is where you're wrong, Tennyson! [ends audio] [goes to table] Once when my revival project is complete, we will be at our greatest plan will complete!

That's when a giant mutant mosquito came in with a black and yellow goo inside it's belly. Soon, Animo did a few experiments with the goo and Polymorph DNA. Then, he grabbed a Polymorph's anti-gravity projector and put the little bit of the goo into it, and the goo transforms into the villain known as Promatheus Black, or Meltdown!

Meltdown: [groans] [rubs his head] Wha- What happened?

Dr. Animo: You've been revived.

It took a moment for Meltdown to look at Animo to realise...

Meltdown: [happy] Aloy! Old friend!

Dr. Animo: Propy! It's been years! [Meltdown goes to hug him] Wait, wait, wait! You're still corossive!

Meltdown: [looks at his hands] I'm still this form. [looks up above him] What is this?

Dr. Animo: A Polymorph's anti-gravity projector. I had to mix your melting goo with a bit of Polymorph's DNA. It took a couple hours to get it right, and now, you're back! But before we continue with my new and improve plan, do you remember our past life?

Meltdown: Well, I remember it all too well.

[flashback]

Meltdown: I was in high school when I first saw you, doing some drawing of some fantasy animal that you thought of.

Aloysius (teenage): There we go. A elephant with a crocodile body and bat wings. [chuckles]

Promatheus (teenage): What are you drawing?

Aloysius (teenage): Oh! Just a animal that I made up. I'm still looking for a name for it.

Promatheus (teenage): How about the flying replephant?

Aloysius (teenage): Oh, that's a great name! You know a thing about animal fusions.

Promatheus (teenage): Indeed I do. [pulls out Voo-Doo doll of a rat with owl wings] I've been working on my own amalgon species. I call it the Nocturnal Rat.

Aloysius (teenage): Wow! We should be friends. My name is Aloysius Animo.

Promatheus (teenage): Promatheus Black.

Meltdown: Soon, our friendship had begun. We started to experiment with dolls and clay models of animals. We manage to get into college and got our zoology deployment. But when we lived together, the landlord didn't want me to be with you due to our experiments, and I left.

[flashback ends]

Meltdown: And then I went to experiment on humans with steroids and my biochemical makeover. But when I want to get rid of the machines from Issac Somdac, I was defeated by those Autobots, three times. But when I was defeated the third time, I melted away to a puddle.

Dr. Animo: Indeed you were.

[flashback]

Dr. Animo: Before I join the Alliance, I manage to track you down and found your lab. I was blocked by three robotic dinosaurs, but I manage to get in. When I was about to revive you in my lab, Eon dragged me away from my universe and was pulled in to his plan. But in the end, Eon slice my head off my body! But not to his knowing, my head was filled with spider and lizard DNA. I grew spider legs and manage to crawl back to Zim's lab to get back to my lab and get into something that will help me survive.

[flashback ends]

Dr. Animo: Now, my life is on the line in this jar. And soon, I'll be going onto a animal's body, hoping that I'll survive the operation.

(This plays with future Animo, going to get onto a gorilla body)

Dr. Animo: But now that I'm alive and you're back, we can go with our plan that we been dreaming before you left. Creating a world full of animal mutants!

Meltdown: Oh yes!

Dr. Animo: But in order for that plan to go into action, we need the blueprints of my enemy's device.

Meltdown: Your enemy?

Dr. Animo: Do you know Ben Tennyson?

Meltdown: Ben. Ben, Ben, Ben. Oh yes, he weilds the strange and interesting device called the Omnitrix, which allows him to transforms into interesting creatures.

Dr. Animo: Aliens, is what they really are. But there is one thing that really interesting to me.

He then pulls out an image of an interesting version on the Omnitrix.

Meltdown: What is that?

Dr. Animo: This is called the Nemetrix. A level 19-20 Omnitrix created by a Cerebrocurstacean and Galvanic Mechamorph when they manage to download it's blueprint. But instead of intellegent aliens, this contains monster-like animals. [shows Nemetrix forms] They will be interesting to experiment with and to transform them, evolve them into new forms from what they were before.

Meltdown: But, it looks like there's only ten forms. And I remember that Tennyson has more than ten.

Dr. Animo: True. That is why we can go to other worlds.

Meltdown: [curious] Other worlds?

Dr. Animo: Ever heard of the multiverse?

Meltdown: Heard of it in theory. Thought to be a myth.

Dr. Animo: [pushes button] Not to my "partner" knowing, I manage to put in a blueprint of Eon's knowledge of the Multiverse in my God Maker, allowing me to look into his mind.

Meltdown: Why did you do that?

Dr. Animo: I thought that, "if one universe has aliens, what would the others ones in the multiverse look like?"

Meltdown: Really? That would be interesting to see.

Dr. Animo: It will be interesting.

Meltdown: So, what you are saying is that we could build the portal to go to these other universes, gather information on all the creatures from that world, and we can create an army of mutant animals and monsters. Brillient!

Dr. Animo: Indeed!

Meltdown: But before we do this project, we need to get you a new body. You won't be able to do a thing with those spider legs.

Dr. Animo: Indeed. And you will be helping me to find the right body.

Meltdown: Indeed.

Dr. Animo: And you will be needing your suit. [presses button]

When he push the button, a robotic arm with Meltdown's suit and glasses.

Meltdown: [smirks]

Soon, they got to work, looking for Animo's new body. There was a couple errors of the right body, some were too small or big for his head, some were not to his liking, and some were too much damage to work. When they found a perfect body the Animo like, they accidently destroyed it.

(plays with future Animo telling his past self about that mistake he made)

Soon, they manage to find an Albino gorilla body. Soon, the new and inprove Animo has arrived!

Dr. Animo: [bangs his chest] [smirks] It's good to be back! Now, let's get building this machine!

Meltdown: [smirks] Yes!

Then, they got to work. But not to their knowing, The Watcher, teen Bunnix, and Syrrus was watching them from the Watcher's walls, in worry.

Syrrus: This is bad.

Bunnix: Oh yeah.

Watcher: It's worst than you think. If they manage to get every creature throughout the multiverse, it could be the end of all life as we know it.

Bunnix: So, what are we waiting for? We gotta do something!

Watcher: It's not that simple, Alix. We have our limits to help our worlds.

Bunnix: I know. I get it. We can go in our original worlds for certain periods of time. But isn't there someone who can go for as long as he or she needs.

Syrrus: The only one who can do this is Paradox, and he only appears when Tennyson has done something wrong.

?: You know when somepeople talk 'bout others who can't threw worlds with limits, they always leave me out.

Turns out, the person that was talking was Discord from Equestria playing with a Bunnix action figure!

Discord: I can be more useful if you protectors for your timelines nicefully. Well, if this a interesting group of powerful people.

Syrrus: [sighs] Discord. How'd you get here?

Discord: I can do anything, you silly two-tailed dragon. Being in these pocket dimension really makes you forget things. I've the creature of chaos and disharmony of my universe, I'm sure I can handle the Watcher's simple walls.

Bunnix: Who's this guy?

Discord: Ah, the bunny superhero. I thought you were taller.

Watcher: This is Alix's pastself, when Ladybug actually-

Discord: Given her the bunny Miraculous to watch over her timelines and then began one of you. [to Watcher] I imagin that Stephan is doing great keeping an eye on Killmonger before Eon pulled him out from his prison.

Watcher: Eon distracted me!

Discord: Yeah, sure. [to Syrrus] And for someone who got beaten by your brothers, you still don't do any battling.

Syrrus: [growls] I'll show you battling! [flies up] [powers up] Hydro Drill! [charges at Discord with drill]

Discord: [yawns] Is this really all you got? [turns into ice cream]

Syrrus: [crashes into ice cream] [grunts]

Discord: [teleports besdie Bunnix] I'm so impressed.

Syrrus: [gets back on his feet] [powers up] [growls]

Discord: [holds Bunnix's Miraculous] I'm impress that this watch is a Miraculous.

Alix: [transforms back] Hey!

Discord: What if I told you three that I found the most powerful, dangerous, and horrible Miraculous of all.

Watcher: Wait. You mean...?

Discord: Oh yes! The Octopus Miraculous, which grants the power of reality! And I know who from Tennyson's universe that has it.

Turns out, the man was the director of the B.P.R.D., Professor Broom. When he put it on, the Bonch turn into camoflage mode, and the octopus Kwami, Cthulhu, came out.

Cthulhu: [yawns] Master.

Professor Broom: It is time to use you.

End! What will the Professor do with his Miraculous? Why did Discord said it's dangerous? Find out in the next chapter of Ben 10 meets DC Super Hero Girls season 3!
