(Author's Note)
Thanks for all the nice reviews!
This chapter took longer to get up, but it's here now.
I've decided on the episodes that I'll be using, including but not limited to:
Time Breaker, Copycat, Evillistrator, Dark Cupid, Princess Fragrance, Gamer, Reflekta, Puppeteer, Antibug, and Volpina.
And that's just Season 1!

Dear Bug,
Never put parties ahead of fighting best-friends-turned-villains. Not that you would, or did, but if you ever feel the temptation, just read this letter again.

Despite the weird, empty feeling in my stomach, I had tried to make the most of the situation. I attempted conversation with a few people over the booming music, but they just smiled, and subtlety stepped closer to the nearest exit.
It was a great moral booster.

After a while, I considered transforming into Cat Noir just to fight off the awkwardness, literally. Then Chloe walked up to me, bouncing with giddiness. Unlike everyone else, she was smiling. Phew! I thought. Maybe she could tell me what exactly was going on.
"Is it just me," I asked, "or does everyone seem a little weird?"
"Forget about them! Let's go dance!"

Chloe grabbed my wrist and pulled me over to the center of the courtyard while the Bubbler switched to a slower song. Everyone quickly pivoted and started dancing with the person closest to them, staring at their shoes. I tried to smile for Chloe, who was probably the only one having fun, but my stomach kept flipping.
Even though it didn't seem to be causing any harm, having fun while one of Hawkmoth's villains was a few feet away didn't feel right. No matter what Plagg had said.

UGH. Why had I listened to him in the first place?

We danced awkwardly for a few more minutes before there was a loud Skrrchhh! (Yes, that's exactly what it sounded like.) -And the music changed to a faster pop song. Almost in relief, everyone collectively let go of their partners and started bouncing on the balls of their feet, swinging their arms.

The Bubbler muttered something huffily, but I wasn't paying attention to him. I redirected Chloe to the snack table and grabbed some pretzels, chewing them nervously. …Where had these snacks come from?

"Yo, birthday-boy Adrien! How 'bout you have a turn runnin' this rodeo! Lay down something fiercely wicked!"
I turned around and gave the Bubbler my most polite I-have-no-idea-what-that-means face. He was holding a microphone and gestured for me to come onto the stage. I hesitated, then grinned as widely as I could without coming off as a crocodile impressionist.
"Sure!"

I climbed onto the stage, gingerly took the microphone, and surveyed my audience. Most smiled, but more than one had an eye twitch.
"Hey, Paris! How're you doing?"
The group shifted uncomfortably. The floorboards behind me shifted. Suddenly, their eyes widened and they all took a step back before laughing and cheering, jerkily clapping their hands.

My stomach rolled again, so I handed the Bubbler his microphone and jumped back down. Something red flashed in the corner of my eye. I glanced up-
"Ladybug!"

Hey, look, it's you again! You threw your yo-yo at the Bubbler's power strip, knocking out the cords and abruptly cutting out the music. I wasn't sure exactly how helpful that was, but it sure looked impressive. Your pigtails bounced as you shook your head at him.
"Sorry, Bubbler, but the party's over!"
"UGH. Why ya gotta be like that?"

You started lecturing the Bubbler about adults while I inched over to my front doors. I dashed down the hall and up the stairs, to my room, in case anybody decided to follow me. Plagg flew out of my jacket and managed to look innocent.
"I think I've been a complete idiot."
The kwami sighed, knowing what was coming.
"Plagg, claws out!"

His energy transformed into mine, and suddenly I was ready to bounce off the walls- because sometimes I needed to be that kind of ready. Your plans could get a little complicated.

With a new bounce in my step and cat ears on my head, I opened a window and leaped to the roof. I almost slipped in the dust but managed to grab my balance and headed for the front courtyard.

You were already fighting the Bubbler head-on, swinging your yo-yo at him. He grunted and threw a bubble in your direction. My eyes widened, and I leaped down as the yo-yo bounced off the bubble, heading right for you.
I swung my baton at it, sending the yo-yo up towards the clouds. A grin broke through my face as I posed, ready for anymore bubbles the Bubbler could blow at us.

"Looks like I arrived just in time," I said, panting.
"Oh, I had it under control." You grinned this time as your yo-yo bonked me in the head, beaming with one eyebrow raised at my look of sheer pain. "But thanks!"

Can I remind you that your yo-yo is a weapon, and not meant for bonking your awesome crime-fighting partner in the head with?

On the other side of the courtyard, a familiar purple outline of wings hovered over the Bubbler's face. He grimaced at whatever Hawkmoth demanded (read: our miraculouses) and smirked at us.

Gripping his plastic bubble sword, he arched it through the air, sending a hurricane of red-tinged bubbles towards us. You and I were ready, baton and yo-yo flashing through it all and keeping the bubbles from touching us. Some of the teens hiding behind the banisters cheered.

The bubbler stared at us with an unreadable expression on his face. Then he snapped his fingers.

Immediately, the bubbles turned green and span back down, this time too fast for me to swat them away. Upon contact they glued themselves to our arms. I shook my arm back and forth, trying to dislodge them, but that just made more bubbles glue themselves to my fingers. When a bubble touched another one, they combined, growing bigger until my arms were encased.

I backed up, still trying to shake them off, tripping into you. With a shout we fell over, until bubble after bubble combined to make one huge green bubble- inside which, you and I were trapped.

You shouted in frustration and slammed the side of it. The Bubbler laughed at us.
"Give me your miraculouses before you run out of air."
You glared back. "Dream on, Bubbler!"
He shook his head. "Party poopers. Just like adults."
"Kids need adults!"
"False! Kids need freedom, fun, to let loose and live it up. Adults are controlling and bossy." He gave you a look. And, to be honest, I could relate. You were a little bossy.
"But kids need adults to keep them safe and protected! They care for their kids and love them!"

Well. Most do. "You must bring the adults back, Bubbler!"
The Bubbler shook his head at me. "Nope, never! You know what? Since you love adults so much, why don't you go join them?!"

He ran at us, sneering the whole while, and furiously kicked us into the sky. The bubble was thrust into the air, slamming us against the slick and slight sticky walls, hurtling until we were level with the top of the Eiffel tower.

You slapped the sides of the bubble, trying to find a weak spot, but there wasn't one. You looked at me with tired eyes. "Use your cataclysm!"
"Couldn't you have said that, like, five hundred feet ago?"
"Well, we can't stay in this bubble forever!"
I paused and slowly gave you a grin with raised eyebrows.
You groaned and held your forehead. I could be a bit of a headache.

"Cataclysm!"
My gut twisted, and my right hand numbed as the dark magic unleashed, hovering on the tips of my fingers. I slammed it onto the bubble, and with a pop! we were free-falling back down to earth.

"Should we see if you land on your feet this time?"
This time? "Yeah, NO THANKS!"
You glanced around before pointing at the Eiffel tower. "Your stick, there!"
I threw it.
You grabbed my hand and swung your yo-yo at it. For a second nothing happened, and we were still falling. My heart plummeted, deciding to meet me at the pavement.
Then we swung, whip-lash throwing my head backwards until we safely rolled onto a patch of grass.

I smiled, panting. "Good thing cats aren't afraid of heights."
You ignored my comment, par usual. "We need to get to his bubble sword. That's gotta be where his akuma is."
Beep, beep!
We both glanced down at my ring. "Better hurry," I frowned.

We ran back to the mansion faster than I would've liked. Sure, I wanted to get this over with, but man was I out of breath.
The Bubbler was glaring at our classmates, hands on his hips. They cowered behind the banisters with the same look in their eyes that they'd had when we were dancing. Ohh. Duh.

"Where is everybody?" The Bubbler growled. "Get out here and party!"
"Oh, sorry to burst your bubble." (Did you come up with these lines on the spot? Do you have a book of awesome one-liners at home that I'll never level up to?)

"LADYBUG! LADYBUG! LADYBUG!"
You shook your head in mock pity. "No-one wants to party with you anymore, Bubbler."
He tensed. "What's wrong with all you guys? Why ya'll gotta be such haters?!" He grunted angrily, swinging his sword in their direction.

Green bubbles shot out, swallowing our classmates, and sending them floating up… up… up… I gripped my baton to keep from leaping at the Bubbler.
"NOO!"
The Bubbler pivoted, snarling. "Outer space is the place for your precious peeps and they're never coming back!" He dashed away towards the Eiffel tower.
Your teasing smile was gone. You snatched your yo-yo from it's place at your side and hurled it after him.

We were right on his tail, but I guess someone failed to mention his explosive bubbles. I cried out, pushing you in the opposite direction. He tossed them at us almost casually, just waiting for one leap in the wrong direction.

Beep, beep!
"I'm gonna change back soon! Hurry!"
"LUCKY CHARM!"

With a flash of pink magic, an oversized wrench landed in your hands.
"Your… plumbing skills are going to save us?"
You shrugged.

Then the Bubbler threw more explosives at me, so I leaped higher until I found a beam slightly out of his range. I was tempted to make a joke about best friends always being warm or something, but I decided against it. You weren't ready for any identity reveals yet.

I resorted to taunting him. "Could use a little work! Is that all you've got?"
He roared and threw more.
From below, you shouted happily. "I've got it!" I risked a glance down to watch you run over to a large pipe before unscrewing it with the wrench. It thrust backwards shakily, air blowing out, over to where I was. "Cat Noir, cover me!"

I jumped down and grabbed the pipe. "Go on!"
The Bubbler sent more bubbles at me, but the pipe blew them away, over his head and out of sight. Before he could send any more, you swung your yo-yo up and snagged his sword. With a triumphant grin you snapped it across your knees. Out flapped a dark purple butterfly: the akuma.

"No more evil doing for you, little akuma. Time to de-evilize!" I dropped the pipe and walked over to you as you swung your yo-yo around, caught the akuma, and released the butterfly from the magic.
We watched the newly purified bug fly away as the Bubbler transformed back into Nino.

"Who? …Dude."

We fist-bumped.

The next day school was in again, and I walked in wearing the new blue scarf my dad had given me for my birthday. Alya and you were standing at the base of the stairs.
"Hey, girls!"
You whispered something to Alya, who grinned and waved at me.
"Hey, nice scarf, Adrien! Off the chain."
"Yeah, can you believe my dad got this for me? He's been giving me the same lame pen for three years in a row."
Alya's eye twitched.

Nino smiled. "I guess anyone can change. Adults can be cool when you least expect it."
"Speaking of adults, I know my dad said you were a bad influence, but-"
"We're good, Adrien. Don't sweat it. We're buds now and forever."

The bell rang, and we walked inside.
