Phantom vs Aliens: Hot Ectoplasma!

Chapter 5: Close Encounters

Danny had returned home, stretching his arms up as he felt a little tired.

His parents were out hunting Z-Lists ghosts that weren't much of a threat and Jazz was on a date with some senior. He was alone right now, not that he minded.

"Finally, a chance to take a break..."He thought, plopping on the couch.

He would have liked to hang out with Sam and Tucker right now but Tucker was in detention for loitering near the girls' bathroom and Sam had a meeting with her protest group, something about planning to take down one of Vlad's new anti-environment establishments that he made just to spite them.

"I guess it's just me..."Danny thought, turning the TV on.

After a few minutes, he was halfway through the film. One about aliens trying to take over the world and find a mate, such as the hero of the movie.

"This alien has a cool design. No wonder Sam said this film's franchise was so underrated..."Danny thought as he watched the movie.

Just then, his ghost sense went off and the ghost boy groaned.

"Oh, who is it this time?...'He grumbled.

"BEWARE!..."He heard from outside and sighed.

"Oh no, not him again and just when I was all cozy..."He muttered, wanting to get this over with and back to his afternoon off.

Wasting no time, he changed into his ghost form and phased outside, wanting to end this fast.

Unknown to him, someone had just entered Earth's atmosphere and was looking him...

Oh boy.

Elsewhere

Mandie's ship had landed in the woods on the outskirts of Amity Park.

"Computer, activate the ships cloaking device..."Mandie ordered, seeing it turn invisible.

Normally, she wouldn't think twice of just crash landing in the middle of town and causing a ruckus, but her mother made it explicitly clear that they were not to make their presence known until they were ready to invade.

Mandie agreed...even if it was kind of boring.

"Let's hope this one is worth it..."She thought as she decided to put on her regular garb, carrying only her flame sword and some gadgets with her.

She wanted to see for herself how this supposed guardian fairs, hopefully he'll put up a good enough fight.

"Best stay hidden for now..."Mandie said before activating her jet boots and taking off to the sky to search for the one she wanted to meet.

Danny Phantom.

Meanwhile

"YOU CANNOT DEFEAT ME, FOR I AM THE BOX GHOST, MASTER OF ALL-..."

"OH, SHUT UP!..."Danny shouted as he quickly sucked the annoying ghost inside the thermos.

Once done, he clasp it shut.

"The last thing I need right now is another one of his annoying speeches..."He grumbled under his breath.

He was about to go fly back home to see the rest of his movie, only for his ghost sense to act up again.

"Again? Who is it this time?..."Danny said in annoyance.

It wasn't anyone he knew, but a large ghost mantis.

"Better zap this bug fast..." He thought as he flew to the creature swung his fist, knocking it back.

It tried to slash at him, but he uses his splitting ability to avoid a horizontal attack before reforming to one and attacking.

Unknown to the ghostly here, someone was watching his battle from a distance.

"So, this is him...the supposed guardian of this universe's Earth..."Mandie whispered as she pulled out her Ultra Glasses.

She quickly hit record and was watching when she saw the blast of energy from his hands, as well as scanning his power levels at the same time.

According to her Ultra Shades, he is about 15 in Earth years, which was 17 in Boudacian years...he also had a very impressive level of strength as he lifted the creature over his head.

"Impossible! These readings are off the charts, it must be malfunctioning..."She said as she saw the ghostly boy fight off against the giant ghostly beast.

Then again, this universe is different from her own.

She saw that he was strong...fast...agile and spirited with how he handled himself on the battlefield

"You know, you're bugging me right now..."Danny quipped, unknowingly earning a giggle from the alien princess.

"He's talkative, that's for sure..."Mandie thought as she watched him give the beast an upper cut, finally knocking it out.

With that done, he pulled out some strange, silver device, trapping the beast inside of it.

"This new earth seems to have some rather advanced technology..."Mandie thought, curious of the device he used. "I wonder if it can be used to advance our armies..."She considered.

The alien princess pondered further but the white haired boy was about to fly away. Frowning, she activated her jet boots and flew there.

She would definitely get a scolding from her parents later, especially her mother...but that was the furthest thing on her mind right now. Mandie just had to go and see for herself what he's made of.

And there was only one way.

With Danny.

He haw just used the Thermos and captured the ghost, he yawned.

"Finally...maybe now I can get back to my movie..."He muttered.

As Danny dusted his hands clean, he had been about to fly home when he heard what sounded like small engines as something landed behind him.

He turned his head... and that is when he saw her.

His eyes widened, his mouth hung agape and his guard was dropped.

"W-What?...'Danny asked as he saw who was before him, the sight what was clearly a female.

What he saw was unlike anything he ever saw.

This creature is a girl...

She is tall, with has long, purple hair, big, glowing green eyes that are much like his own, yellow skin, elf-like ears, black colored lipstick and she also has a pair of curled antenna on her head resembling that of a butterfly. He also noticed that she is wearing a pretty revealing white and blue outfit, with fancy looking gloves and boots, not to mention a lot of fancy looking jewelry.

He also noticed something else about her too.

"Beautiful..."Danny thought, his mind going blank.

He was so stunned, he didn't even realize that she didn't even trigger his ghost sense yet. Mandie, meanwhile, scratched her chin in thought as she approached him, finally getting a closer look at him.

As Mandie looked him over, she felt a smile on her face.

"He is quite cute..."She thought as she eyed him some more, feeling a strange sense of emotions that she wasn't familiar with.

She is pleased with what she sees but noticed something.

"Hmm... he's... a bit shorter than I thought he'd be but that's not a deal breaker..." She thought to herself. "He's got a cute enough face, so that's something. Factoring in growth and potential training and his scrawniness, though cute, wouldn't be an issue. Yes... I think he'll do, at least in the physical department..." She thought with interest.

She sauntered to him, wanting to get a closer look while the ghost boy eventually snapped out of it and got on the defensive, raising his hand up.

"Whoa, hold it!..."He said defensively, only to finally notice something.

"Wait...why didn't my ghost sense go off?..."Danny thought, now taking a few steps back as he realized this this beautiful but strange girl wasn't a ghost at all

Mandie couldn't help but smirk at his reaction.

"He must not be used to an alien, or someone who looks like me..."She thought with a giggle.

She wanted to test him now. However, she was a princess and had to maintain some decorum, while also being a tad flirty.

"Tell me, are you Danny Phantom of Earth?..." She asked with hands behind her back, trying to look cute as she spoke.

Danny blinked in confusion, not dropping his guard but since she didn't attack him yet, dropping his glare. Realizing the beautiful girl was speaking to him, Danny snapped out of it.

"Uh... yes..."Danny said, confused over who and exactly what this hot girl is anyway.

It was then that he noticed how she worded her sentence.

"Wait... what do you mea-..."He was silenced when she spoke again.

It it enchanting to meet you, Phantom...I am Princess Mandie of the planet Boudacia...I have come all this way from beyond the stars to come to this planet and wish to test your power..." She said in a formal tone, due to being raised as a princess and she wanted to handle this her way.

It just hit what she said.

"Bou-what? Did... you just say planet? As in... an alien?!..." Danny asked.

"Of course..." She said.

Suddenly, his eyes lit up, looking excited.

"AN ALIEN?! AWESOME!..."Danny exclaimed, the space geek in him was thrilled.

However, he then realized what she just said and was confused.

"Wait, what did you mean by test my-..."

"KYAAHHH!..." She came in, swinging her sword.

She then charged at him, intent to use it.

"WHOA!..."Danny shouted as he raised his hand up and created a shield for protection.

Mandie's eyes widened at the shield, but resumed her assault.

"Impressive, but what of your offensive capabilities?..." She asked.

"Uh... I don't swear..." He said as he kept defending himself.

"Not that kind of-...never mind..." She said before pulling back and aiming her blaster from her wrist.

She fired. Danny responded with a blast of her own but the impact caused a small explosion as Mandie covered her eyes. Once it was done, she saw Danny was gone.

Seeing an empty crater still smoking, Mandie groaned in disappointment.

"Loser... and I had such high hopes for this one too... He was so cute..." She crossed her arms. "Well, I guess-..."She never got a chance to finish that statement.

Suddenly, she was pushed by something that came out of the ground. It was Danny Phantom, flying at near top speeds.

"Did you miss me?..." He asked with a smile.

Mandie smiled in relief.

"So, you have some fight in you, after all..."She said, smirking.

She then kneed him, making him let go. With that, she landed gracefully on her feet.

Fists charged, Danny flew at her. He threw a punch, she kneed him in the chest, he tackled her, she chopped him in the back.

"GAH!..."Danny let out before getting mad.

They went back to fighting, with Mandie swinging her flaming sword back and forth in various swift motions, almost as is she was dancing. Danny was dodging and managed to outmaneuver her attacks.

This impressed Mandie, but that didn't mean that she was stopped her onslaught of attacks as she used her rocket shoes to lift herself up in the air, only for to free fall her way towards the ghost boy. Mandie came down, her weapon ready but Danny raised a shield for protection.

"Come on!..." She shouted as the blade failed to go through.

"Sorry... but you'll have to try harder!..." Danny said playfully.

He pushed back, making her lose her footing. Danny then kicked her back.

Not finished, Mandie tried slashing him, but his shield did not break once.

"So far...she's just trying to attack with her sword and her fists...I don't think she has any other powers...which means..."Danny smirked as he got an idea.

The ghost boy quickly became invisible, shocking the alien princess.

"Where did you go?..."Mandie exclaimed as she looked around.

"What's a matter, can't hit what you can't see?..."Danny's voice was heard.

Mandie frowned as she held her sword tighter in her hand.

She swung her flame sword as swiftly as possible, but her flaming blade met only air. She heard the ghost boy's voice again behind her a few sent with the same results.

Angered, the princess stabbed the ground as flames burst out. She doubted her for was hit, but it helped with her boiling anger. And yet, something else was rising.

"Come on out and fight! I know you're here somewhere..."Mandie shouted, feeling angry and strangely excited by this turn of events.

However, she didn't get a chance to think about those emotions as a fist landed in her stomach. It felt strong, enough so that Mandie had to step back. But she slipped on ice Danny had spread. Her grip loosened as her sword flew out of it.

Mandie seethed in anger at the reappearance of Danny. The ghost boy lifted her with ease, almost mocking her with a smile.

"Put me down!..."Mandie commanded.

"Why do bad guys always say that when you do this?..."Danny said as he managed to throw her to the ground, making her painfully crash there.

"Not like that...ow!..."Mandie said in a pained daze as the ghost boy hovered with his arms crossed and a smile on his face.

"Finally..."Danny said, unaware what was going through this alien girl's mind right now.

Panting wildly, Mandie smiled.

"No one has lasted this long against me... no one..."Mandie whispered in amazement, feeling so many emotions right now.

The ghostly boy then floated closer to the ground, still frowning at her.

"There...you saw how strong I am...and unless you want me to kick your butt again, I suggest you leave and never return. That is not a threat, but a promise..."Danny said, trying to sound tough.

Unknown to him, he just sounded cute to the alien girl, who was still feeling those emotions.

"He's so strong..."She thought as got up and sent a smile to the ghostly boy...one that he noticed.

"Uh, why are you looking at me like that?..."Danny asked, weirded out while the alien girl kept sending him that look.

Her mind was filled with something other than rage right now as she continued to eye the white haired warrior of Earth.

"Good looking and strong...and he's actually managed to beat me..."Mandie mused as she thought about doing something to him now.

Someone not painful...and something she kinda liked to do, to be honest.

Reward him for being the only man to ever beat her in combat...and she knew how.

"Well, he DID best me in battle...I think he deserves it..."Mandie thought but deep down, she liked the idea.

"Time out..." She said, confusing him.

"Uh, what?..."Danny said and received no answer as he just watched.

The princess then pulled out her compact mirror and some lipstick and began to fix up her hair.

"Never thought this would happen...but as I said, he did manage to best me...so, why not?..."She thought as she did her make up, wanting to look her best as she was about to grant the earth hero his reward.

Danny was somewhat annoyed and confused by what was happening.

He had no idea why this stunning alien princess attacked him or why she was applying makeup right after their fight of all things.

"Uh...are you gonna keep this up or did you forget you're going dancing tonight?...'Danny asked, clueless as to what she was up to.

"Just a moment!..." She said. Danny groaned loudly, much to her annoyance.

"I heard you!..." She said before she finished powering face and putting lipstick on.

Once done, she put it away and turned to the ghostly boy.

"Done... now then..."She said slowly before she jumped into the air.

"Not again!..." Danny said, raising his shield with one hand, thinking she was going to attack again.

Mandie, however, anticipated this.

"Not this time..." She thought as she had other plans.

With a foot, she landed on his shield, jumping off and somersaulting to land behind him. As Danny turned around, he saw Mandie throw her sword into the ground, much to his confusion.

"Hey, what are-..."He was silenced when the alien princess then grabbed him by the face and pulled him in, allowing her to get a good look into his eyes.

She smiled as she looked into his confused green eyes.

"You fought well, Phantom. You've earned this..." She said before kissing him with mouth wide open.

Eyes open beyond their limits, Danny froze up.

"HUH?!..."Danny thought with wide eyes, freezing up.

"Mmm~..."Mandie let out as she held him in a vice like grip, not wanting to let him go.

All the while, the ghost boy's mind was racing a mile a minute.

"I'm not dreaming all this right? Is this actually happening? Am I kissing an alien princess?!..."He thought frantically before his mind went blank.

He made no effort to fight back, or react at all, as this strange but beautiful creature continued to kiss him.

As Danny's arms lowered, Mandie's hands moved down from his face to his shoulders and she held onto them, keeping him from pulling back. Danny could only stare into her eyes as she opened them slightly to give him the bedroom eye look before closing them again.

Finally being able to think again, Danny's arms rose and wrapped around Mandie's frame, stopping a moment as it seemed like her was hugging her.

At first, he felt his teenage hormones were kicking in but did his best to resist them and gain control over himself. He wasn't sure what he was doing, but it finally kicked in and he pulled with enough force to break Mandie's mouth from his.

He had his arms wrapped around her and lifted her up.

"You're not going anywhere!..."He shouted, looking angry and confused over what just happened...as well as flustered.

Mandie only smiled coyly at that and didn't bother fighting back.

"I take it you enjoyed that..."She said with some mockery while on the inside, she was elated.

That was the first time she ever kissed a male, not even one of her race. While she technically did marry Mark for a while, she never kissed him nor had she had the desire to do so, she just wanted his kingdom. She also never kissed any of the many suitors she had since they were not worthy of even her time.

However, Danny Phantom lasted longer than 10 minutes, not even Brutis can do that.

Danny ignored that as he flew up, preventing her from escaping.

"Okay... you're gonna tell me what you're doing here? Alien or not, what do you want?..." He asked and Mandie looked like she was about to answer him.

Suddenly, a timer went off from Mandie's arm and, to his surprise, she groaned.

"I gotta get going... sorry..." She pressed a button on her wrist. "My parents expect me home soon..."She said, pouting a bit.

"Parents? What are-..."He never got a chance to finish.

Suddenly, a ship came at them for her and Danny's jaw dropped at the sight of the UFO.

"No way..."He let out while Mandie sighed.

As she took one look at Danny, she spoke under her breath.

"So annoying... but..." Mandie smiled, her face turning red. "I think I like this one..." She then swung her arm out.

With that, the door opened and she walked inside.

"I better get home. When I come back, let's play again! Later, Phantom..."Mandie said with a wink before the ship's door closed.

Before he could do anything, the ship was gone in lightning fast speed, already out of the atmosphere before he could do or anyway.

Danny had a look on his face that made it clear he had no idea what to think of that.

"What...just happened?..."He let out, looking totally lost over what happened in the last 15 minutes of his life.

Meanwhile

Mandie flew back home at top speed in her star ship, setting the new coordinates for her home planet.

As she set the ship on autopilot, she place a hand at her mouth.

She was still marveling over the kind of battle she just had with the Earth warrior...and what it lead to.

"My first kiss... and from a warrior who lasted long enough to impress me and even best me..."She said, still having a strange smile on her face as she felt a blush form on her face.

She thought more about it, before giggling.

"I shall keep an eye on this one...maybe mother's suggestion was wise after all..."She thought, still blushing as her space ship was on it's way home.

Both she and the white haired warrior of Earth were unaware of it right now, but encounter would lead to events that would change both their destinies forever.

However, it has yet to be determined if it was for good or bad.
