Hey, everyone! I'm back with Ben 10 meets DC Super Hero Girls Mayhem in the Multiverse! Let's begin!

I DON'T OWN ANYONE IN THIS SERIES!*

Last time, on Ben 10 meets DC Superhero Girls Mayhem in the Multiverse, Ben and his team went to Kara's cousin Fortress of Solitude, get Kryptonian crystals, and escape leaving Ben to deal with Superman! Now we see the Autobots driving the girls to a safe place.

Batgirl: Thanks guys! You guys are life savors!

Bulkhead: Anything for our friends.

Green Lantern: Hope Ben's doing alright.

Rook: If he is using Full Stop, he would be using his Powerhouse Playlist.

Supergirl: I'm sure my cousin is getting in pain with my babe.

Wonder Woman: [to Optimus Prime] Where are you taking us?

Optimus Prime: We're taking you all somewhere safe, somewhere that Superman can't find us.

Turns out, the Autobots took the girls to Detroit's Sumdac System's tower. Soon, inside...

Issac: Well, let me just say, it's an honor for the friend's of Ben Tennyson to have you at my lab.

Green Lantern: You know us?

Issac: Oh yeah, Sari told me all about you a lot. But she would go on all day with the one called Supergirl. She's really into her.

While they were talking, the villains crossing off the heroes that they token care of.

Star Sapphire: Ooh! I can't wait till those Super Hero Girls show their faces.

Catwoman: And we send them to limbo for eternity.

Legion of Doom: [cackling]

Peng: Don't get cofinident yet, mortals. Those slimy heroes are toughfull then you think.

Killmonger: Don't matter, they're be died before they could do a thing.

While they were talking, Harley was worried about the things they were saying, thinking about her friend.

Harley: Yeah, but since it's eternity, we got time. I mean, it's not like we have to send them to limbo today?

While they were talking and laughing, Lex went towards a door and went inside the room. While he was in the room, Cythonna's spirit was there, and they talk.

Cythonna: You must be so proud. As their cofidence grows, so does their malevolence.

Lex Luthor: Have you forgotten, Cythonna? You are a silent partner.

Cythonna: [scoffs] Of course not. I appear to only you, in this astral form.

Lex Luthor: [as she vashes through him] [shudders]

Cythonna: Albeit, weekly for, as you know, my powers are limited while I remain trapped, within this cursed prison forever.

Lex Luthor: It's not all bad. Possessing your prison, grants me access to that limited power.

Cythonna: In return, I only ask--

Lex Luthor: Oh, I know what you want. And perhaps once, I, Lex Luthor, am victorious, I will indulge you. If I'm in a good mood. [leaves room]

Cythonna: You haven't begun to know what I want.

Turns out, the amulet was cracking! Back to the heroes...

Kara: We're gonna defer to the League? Okay, I'll admit. I don't know what defer means, but I'm pretty sure you told him, we just roll over. Since when do we back down from a fight?

Ben: Yeah, that was a bad move, D.

Ratchet: Yeah, not a smart idea that you just did, Diana!

Kara: Yeah. Are you afraid--

Diana: I am an Amazon! I fear no fight. Kara, your will is the strongest of any warrior I have known. And while that is part of what makes you so mighty. It can also make you vulnerable when you allow it to become bullheadedness. This brings me no pleasure either. But you chose me as your leader, not to make popular decisions. But the tough ones.

Ben: I get that, D. But when I lead my team, I think of my friends then the missions.

Kara: Yeah, and what if the League blows it? Then what, huh?

Rook: I'm not good with their plan failing.

Then Diana went outside sadly.

Diana: [sighs wearily]

She then got a text from an unknown person to the Daily Planet. Soon, Wonder Woman went to the Daily Planet, where she was waiting for the mystery person.

?: Bet your frends are mad at you, huh?

Turns out, it was Superman!

Wonder Woman: Superman? This was from you?

Superman: From him, actually.

Then came out Batman!

Batman: [indistinct bat grunting]

Wonder Woman: Join you! I am sorry, but I already belong to a team. A team you dismissed!

Superman: Look, I don't know you well, but I do know you've never back down from a fight against evil. The only reason you stepped aside was to protect them. Because at the end of the day, they are just kids.

Batman: [indistinct bat grunting]

Wonder Woman: And how exactly am I different, Batman?

He then pulls out a ancient pot with her incraved on it!

Superman: You're no kid. You got more combat expertise than any of us.

Wonder Woman: I have sworn to protect this world and to stand up to any threat. But-- [sighs]

Superman: But you're worried about dissing your friends? This is bigger than that, Diana. If Luthor wins, a lot more than feeling are gonna get hurt.

She thought for a second about her friends. Meanwhile, with the others...

Jor-El: My precious son, Kal-El. There is much you must know about ancient Krypton.

Zatanna: Uh, Kara. I know this is like a piece from you lost planet. So, please don't take this the wrong way, but, snore.

Green Lantern: Zee, don't be rude! But can we just skip to the part about the amulet?

Jazz: I don't know. With this cool info about Krypton, I can really dig it.

Supergirl: For such a technologically-advanced society, our home media playback systems were surpisingly awful.

Jor-El: Then deglaze the pan before adding the mushrooms. Cremini mushrooms of planet Earth should be good.

Ratchet: Clearly.

Batgirl: You mean, we gotta sit though all of these? That'll take days.

Ben 10: And we don't have time for that!

Bumblebee: Not if I can get my data interface device up and running. I'll be able to download everything in seconds. But if not? Then, yes. It'll take days.

Bumblebee (Autobot): Man, this'll be torture if we watch all of these!

Batgirl: Uh. Isn't there at least a fast forward?

Supergirl: Ugh, we weren't cave people, Barbara.

She then fast forward the crystal's video.

Jor-El: My sweet, beloved, cherished, Kal-El.

Batgirl: Uh. And I thought my dad was mushy.

Jor-El: My role as Krypton's lead ancient historian, is just as important as my role as, lead scientist. My role as lead economic advisor- Lead municipality specialist-

Zatanna: Lead flash fryer and tomato slicer at Krypton's number one fast food chain-

Supergirl: [shushes] Here it is.

Jor-El: Long belived to be merely a relic, from a lost science. The amulet of Cythonna, is, in fact, something far more sinister. For as impossible as it may seem, the crystal within, does in fact, contain the essence of the goddes of darkness.

Bumblebee: Wait... The actual goddes?

Bulkhead: No way!

Jor-El: For eons, the imprisoned Cythonna has floated the cosmos, in search of the one thing that may free her. Evil! She feeds on the souls of the wicked.

Green Lantern: Like Luthor and the Legion of Doom.

Jor-El: The souls will become her servants and, in turn, create more evil for her to devour.

Batgirl: Ooh, I get it. Luthor isn't using Cythonna. She's using him. That's actually way worse.

Bumblebee (Autobot): You think!

Jor-El: Once she has become strong enough, she will free herself from her prison. She will assume, a new Kryptonian vessel and reclaim the universe as her dominion.

Girls: [gasp]

Green Lantern: The League has totally underestimated what they're up against.

Zatanna: [gasps] We have to warn Aquaman. I mean, the League. We have to warn the League.

Bulkhead: You have a crush on him, Zee?

Zatanna: What, no!

Batgirl: I'll call Diana.

Green Lantern: Kara, what do you think your uncle meant by a new Krytponian vessel?

Supergirl: I don't know. Well, I guess we could listen to some more of my uncle-

Green Lantern: I was just curious.

Zatanna: No, way.

Optimus Prime: [to Supergirl] It's kind of you to hear your uncle's lessons, but I think it's best that we leave it at that.

Batgirl: Guys. Diana's is not answeing.

Back to the Legion, Luthor was tinkering with the amulet.

Lex Luthor: My trap has been set. Any remaining heroes who oppose me will be crushed.

Cythonna: But what of the Kryptonian.

Lex Luthor: Look, I haven't forgotten your request. Perhaps I'll honor it. If it suits me.

Cythonna then used her power to control Lex Luthor!

Lex Luthor: And it does suit me. The Kryptonain you require will arrive shortly. [snaps out of her control] [walks away]

Cythonna: The Legion's evil is making me stronger by the second. Soon, I shall be free.

Back the the girls, they were searching for Diana.

Supergirl: I don't see any sign of Diana up here.

Bumblebee: I'm coming up empty too.

Zatanna: Ugh, we better regroup.

Green Lantern: So the last any of us heard from her was that group text, from an hour ago.

Batgirl: Right! The one that just said, "I'm in"?

Supergirl: Yeah, but in what?

Zatanna: Actually, looking at this text, I think the real question might be, who are all these other numbers she included on that text?

Bumblebee: I just assumed it was another one of Diana's tech goofs, because I don't reconize any of the numbers.

Supergirl: [looks on her phone] I do. This is Clark's.

Green Lantern: [looks on her phone] And this one comes up as John Stewart.

Batgirl: [as she and the others meet up at Sweet Justice] Batman's emergency line is here too.

Bumblebee: So, maybe including these other numbers wasn't a mistake.

Supergirl: But including ours was.

Batgirl: And when Diana said "I'm in," she meant...

Ben 10: In the Justice League.

Girls: [looks sad]

Zatanna: [looks on her phone] [eyes sparkle] Just curious. That would make this last number Aquaman's, right? [giggles]
