U-um... this is my first AT fic... so yeah. Enjoy, dear readers!

It just happened. A male vampire – a really rare occurrence in the Land of Ooo – was standing in front of Candy Kingdom's most beloved ruler; the young princess Bubblegum. And the first question that popped out of the young ruler's busy mind was; "HOW?!"

"Whoa. I wasn't expecting a pretty fine lady like you to be the first thing I'll b seeing in front of Gumball's antique mirror." The vampire said, floating in midair.

"I was kinda expecting my handsome self. But, hey! I ain't complaining!"

Still, Princess Bubblegum was speechless. She quietly observed the young man in front of her and all of sudden, all she saw was black darkness. She can hear his voice, as if panicking. She ignored it though, and tried to open her eyes. But, she failed.

"A dream." She whispered. "A weird dream." She repeated. The princess rubbed her eyes and sat up. But before she can do so, a figure was hovering above her.

"Oh cool. Princess is awake."

"GYAAAAAAAAAAAAAAAAAAAAAAAAH!"

Peppermint Butler hurriedly went to the princess's room. "Your highness? I heard a blood-curdling scream, was it-"

"OMYGUM PEPPERMINT BUTLER! TH-THE-THERE'S-" Princess Bubblegum was shaking, holding a lollipop in her hand as if a weapon, in the room's corner and pointing at midair.

"Y-your highness..." the candy butler said, trying to calm her.

"—AN INTRUDER IN MY ROOM!"

"Pardon?"

"H-he was floating like Marceline and—and... he... " she was calming down a bit.

"Yes, your highness?"

"He's not here."

A little later, after the small commotion the princess created, she proceeded in calling someone who knows more about vampires than anyone else – the Vampire Queen, of course. She was pacing back and forth, as if unsure of her actions. But she knew that only Marceline can help her out.

"H-hello?"

"Bonnie? You? Calling me? Is the world about to end?" the Vampire Queen said in the other line. The princess rolled her eyes and pouted.

"Shut up."

"I am just joking around princess. No need to use the royal "shut up" on someone as low as meeeeee~"

"MARCE! I AM HAVING AN EMERGENCY HERE!"

"Chill. I am all ears."

The princess inhaled then exhaled, calming herself down. "There's a vampire lurking around my castle and I need your help or probably advice on this one."

This seems to catch Marceline's interest.

"I'm listening..."

"Just come over. We'll talk about it."

Marceline giggled. "I thought you hated me."

This caught Princess Bubblegum off-guard. She looked down guiltily and sighed. "Just come over, Marce. For old times' sake and for that vampire lurking around here."

The Vampire Queen smiled and laughed. "Sure thing Bonnie. I'll be right over."

They both hanged up, at the same time. This made the princess smile slightly. As she placed her phone down on a nearby table in her room, she walked out in the corridors, seemingly thinking deep about something.

"For old times' sake, what am I-"

"Hey princess, why so glum?" All of a sudden, the lurking vampire appeared in front of the young ruler, upside down, floating above her. And as an instinct, this made Princess Bubblegum shriek and slap the living daylights out of the vampire. He fell down from floating and stumbled to a wall. She gasped and ran to his side right away. Women instincts once again.

"Oh my gosh! I am so sorry-"

"You slap real hot, princess." He said as he winced, massaging the damaged cheek that the princess placed all her fright on.

"I-it's your fault too! You just... popped out!"

"No biggie, right, princess?"

"Would you quit calling me 'princess'?"

"Why? Hate it?"

"N-no, it's just that-"

"Would you like 'angel fluff' instead?"

Princess Bubblegum's mind stopped for a while. For the first time, the genius ruler's mind stopped thinking for a while. For a very long time, she realized that's she's blushing.

"D-don't you know... that... I am a real princess?"

The vampire was a bit shocked himself.

"What? Seriously?! REALLY?"

"Uh... yeah. Basically."

"Shit." He floated back and forth, kind of panicking. The princess was a bit confused at the young vampire's sudden actions.

"W-what's wrong?"

"You must be what they call a 'Parallel Person'..."

"A parallel what now?"

They young vampire floated his way in front of the young ruler and tried to say something. Princess Bubblegum felt the chill on her spine. "You must be Gumball's alternate."

"What?" asked the baffled princess.

"Hey, PG. What's this?" Fionna, the young adventuress, asked as she peered on an old, musky mirror. The young prince turned to her, and then smiled gently.

"That's an ancient mirror my ancestors left. Nobody was seen to use that, thus I don't know what it does exactly." He explained at the curious young girl. Her loyal cat, Cake, came to her side and poked the glass of the mirror.

"Whatever it is, it sure is old and weird."

"That's why it's ancient, Cake." Fionna said and brofisted her bud. As Fionna peered even more and tried to poke the mirror, Prince Gumball covered the said mirror with a white cloth.

"Alright ladies. That's enough poking and peering. You never know what this mirror can do."

Fionna and Cake whined that made the young prince chuckle.

"Okay okay, enough with those faces. I'll bake you some chocolate chip cookies. Come on now, let's go down."

The two buds high-five'd each other then went along with Prince Gumball.

Little did they know, a certain Vampire King had already discovered the mirrors abilities.
