Miraculous and The Flash crossover: Collision of Worlds. (Book 4)

Chapter 1

(CLAAANK!)

Ladybug: (Ughh!)

Flash rushes up a meter from the red-and-black heroine.

(WHOOSH!)

Flash; It's vengeance!

Ladybug quickly gets to her feet, and she throws a couple of punches and a roundhouse kick, towards Flash. But he narrowly dodges her strikes, grabs her leg, and swings his arm. Hitting her in the stomach.

Ladybug: Urrk!

This attack slightly phases Ladybug, but she shakes it off. And Flash deflects and blocks more of her punches. All while trying to get some hits of his own in, but with no success. Ladybug, however, doesn't hold back.

Ladybug: GRRRRAAAH!

As Flash tries to throw another punch. Ladybug blocks and delivers a left hook his way, sending him reeling.

Flash charges towards Ladybug, again.
And the citizens of Paris watch on their televisions, as Clara Contard reports on the ensuing fight, below.

Clara: "No one's sure why they're fighting all of a sudden, folks. But it looks like a clash of titans, from here."

Ladybug: You think you can take me down, Flash?!
YOU'RE JUST ADDING FUEL TO THE FIRE!

Ladybug sends another flurry of punches Flash's way. He keeps blocking, and soon intercepts one of her attacks, and knocks her backwards with some rapid punches. Before sending a powerful strike to Ladybug's right cheek, drawing blood from her mouth.

Flash: You of all people should know, rage is a fuel that burns quickly, Ladybug.

Ladybug wipes her bottom lip, and spits out blood.

Ladybug: It's a good thing I've got a full tank, then!

She charges towards Flash again, and he blocks her. As she alternates her kicks, and begins throwing punches at a rapid pace. Flash also counters a few of her rapid punches with his own. The resulting impact of their blows creates shockwaves that shake the surrounding area. And when the two heroes draw back and punch, the resulting shockwave impact manages to shatter multiple windows in the surrounding area, and setting off nearby car alarms.

(BOOOOOM! HonkHonkHonkHonk!)

Throughout multiple areas of Paris, the brawl between Flash and Ladybug is seen by Alya and her family, Tom Dupain from the prison, Chloe and Zoe from Le Grand Paris hotel, Alix Kubdel, Felix and Amelie in London, and Gabriel and Nathalie, in the Atelier, and many more.

Ladybug gets an opening by deflecting one of Flash's punches, and delivering a backhand punch. He shakes it off and continues deflecting, and blocking more of her attacks. Ladybug charges attempting to leap onto Flash's shoulders, to wrap her legs around his neck. However, Flash vibrates his molecules, and she flies right through him. Ladybug is surprised by this maneuver.

Ladybug: What the-?!

Ladybug lands and Flash spins around, delivering a powerful kick, knocking her backwards.
Ladybug gets up, and continues her attack, as Flash deflects her punches. But Ladybug doesn't let up. And finally lands a hit, making Flash's nose bleed. Ladybug drives Flash back as she continues blocking and sending more kicks and punches Flash's way.

Flash: Funny thing about anger, Ladybug. It's like darkness. You let it consume you, and soon enough…

(WHOOSH!)

Flash dodges, and disappears from her sight. She looks all around her. And Flash reappears directly behind Ladybug.

Flash: You lose sight of everything.

Ladybug's expression goes from bewilderment, to frustration.
As she swings her arm to hit him, but misses. And she quickly turns around in time to see Flash give her an uppercut. Just as another thunderclap is heard.

(Whaap! KRAK-THOOM!)

Ladybug is sent flying into the air, and lands on the ground, hard.

Lila covers her mouth in shock, while Cat Noir is wide-eyed as his polka-dotted partner hits the ground.

Cat Noir: Ladybug!

He rushes to her side, checking to see if she's still alive.
He breathes a sigh of relief, when he realizes she's still breathing, before looking back at Flash.

Flash: Sorry, Cat. I did what had to be done.

Cat Noir: I understand that, but did you have to knock her out?!

Flash: I think you and I both know, she wasn't going to stop, otherwise.

Ladybug: Ughhh.

Ladybug slowly regains consciousness, and Cat Noir helps her to her feet. She briefly holds her head, and looks at Flash.

Ladybug: (Huffs) You're right, I wasn't going to.

Flash looks towards the lamppost that he tied Reverse Flash and Falena Falco to. Only to see that they escaped.

Flash: Ugh, great! Thawne and Falco got away.

Ladybug: Well, who's fault is that, I wonder?

Flash scowls at Ladybug, as he turns back to her.

Flash: Maybe if you weren't so bent on trying to kick the tar out of Falco, we could've gotten some answers from them!

Ladybug: Oh, so now it's my fault that they escaped?! Is that what you're saying?!

Flash: Yeah, that's exactly what I'm saying!
Because you let your emotions cloud your judgment, again! Why can't you ever learn to take some responsibility for your actions?!

Lila watches the chaos continuing to unfold.

Ladybug: Don't talk to me about responsibility!
You don't know anything about me! Or what I've had to do to protect Paris, and the entire world, from Hawk Moth! All while constantly having to deal with irritations like…like-

Flash: Like, Lila and Chloe?! Is that what you were going to say?!

Ladybug is aghast by Flash's inquiry, her eyes widened in shock. Ladybug and Flash turn to see Lila Rossi holding her umbrella, and walking slowly towards them.

Lila: Is that what you think of me?

Ladybug is completely speechless, not knowing how to reply to Lila's statement.

Lila: It is, isn't it? I mean, I know you can't stand me, and that we aren't exactly friends. But I never expected your hatred for me to be this intense.

Ladybug just says nothing to Lila, and looks away.
Lila looks at Flash for some answers.

Lila: Flash, who was that weird future Hawk Moth, anyway? Do you know?

Flash rubs the back of his head, trying to find the best way to break it to Lila.

Flash: Lila…well. There's no easy way to say this…but that future Hawk Moth, was an adult version of you. We saw it for ourselves.

Lila looks at Flash completely shocked and speechless.
Cat Noir decides to break the silence, and steps between Ladybug and Flash.

Cat Noir: Perhaps, we should all take a breath.
I mean, we're all just a little tired from fighting supervillains, and getting ambushed by that weird yellow version of Flash.
