Those Obnoxious Ghosts

Chapter 2: Meeting the notorious Lum

After the arrival of Mr. Invader, everyone moved back into the living room and soon the large man and the government agents explained the entire situation.

"Everyone, this is Mr. Invader, ruler of the planet Uru. They've come to conquer our world, and they choose a random citizen of our world to act as its champion..." The lead agent says.

That is where the catch comes in...

"Say what?! You guys want me to fight this guy?!..." Danny exclaimed in disbelief.

"WHAT?!..." Maddie exclaimed while Jack and the others looked stunned.

"That is correct, Mr. Invader and his people have given a condition regarding the invasion of Earth..."The man said.

"They have randomly chosen an inhabitant of earth, you, to get in a duel with him and if he loses..."One of his lackeys added.

"We will go back to our planet in peace..." Invader said with a smile.

Danny blinked in surprise, but paused a bit.

"Really? If I win… you'll go away peacefully, without a fight? Just like that?..." Danny questioned, feeling a little suspicious.

"This doesn't sound like a typical alien invasion...and who would give the enemy a CHANCE to beat them?..." Jazz called out.

Something seems weird here.

"Yes, on my honor.. .You see, my race is a warmongering one, but we also believe in giving people a fighting chance, as a sign of honor..." Invader said and Danny blinked.

"Honor?..." Danny repeated.

He couldn't believe this, he has to face against an alien in a duel if he wants to save his planet from being invaded. Naturally, he would be all for fighting this guy if he was Danny Phantom, but they are expecting Danny FENTON to do it...

"Geez, what did I do?..."Danny thought as the strange guy from earlier now got down on his knees.

"Please, dedicate your young life to saving our planet..."The man begged.

Danny's parents got mad now.

"WHO ARE YOU TO MAKE SUCH A DEMAND?! YOU'RE EXPECTING A YOUNG BOY TO FIGHT YOUR BATTLE?!..." Maddie shouted in outrage.

"WHY SHOULD OUR SON HAVE TO RISK HIS LIFE? WHY CAN'T YOU OR AN ADULT DO IT?!..." Jack shouted, just as angry. "I'M HIS FATHER, WHY NOT ASK ME?!..."He suggested, not wanting his son hurt or worse.

"It does not work like that..." Mr. Invader called out. "It's a random selection. Your son just happened to be the one chosen from the names we gathered..."He said, like it was no big deal.

Danny's parents looked mad.

"Well, you can't just waltz in here and-..."They began to protest, however, Danny stopped them, surprising everyone when he turned to their unwanted guests.

This is so messed up but if he does nothing, the world will be taken over by aliens and as strong as he is as Danny Phantom, he is not sure if he could take on an entire race of invading extraterrestrials by himself. At least this way, he just has to face one opponent...even if this guy is big and intimidating looking...but he has to be sure about something before he agrees to any of this.

"If I fight you...what are the rules of the battle? What's allowed and not allowed?..." Danny asked, having experienced a lot of trickery in the past.

He has to make sure he doesn't let this creep fool him. Invader however, let out a hearty chuckle, and for a moment, he sort of reminded Danny of his own father, before he answered.

"Actually boy, I am not going to be the one you will duel with..." Invader said and Danny blinked, while Sam, Tucker, Jazz and Danny's parents also looked confused.

"You aren't...then who?..." Danny questioned and got a bad feeling.

If this big guy isn't going to be the one he fights against to save his world...then who?

Suddenly, there was trembling and strange noises.

"Huh? what's going on?..." Danny questioned.

"Right on time, your opponent has just arrived..." Invader said.

"My opponent?..."Danny questioned, getting nervous.

Before anyone realize, a lighting bolt busted through the roof, sending everyone flying back. Danny hit the wall, groaned and was nearly blinded by this light.

Once it faded, he opened his eyes and saw that a new person joined the room.

"Huh?..." Danny let out as he saw who is here now.

It's a girl!

Danny saw what looked to be a slender, busty teenage girl with long green hair, big, innocent looking blue eyes with a hint of blue eye shadow, and probably her most noticeable feature is that fact that she is wearing nothing but a tiger striped bikini and boots, showing off her body. He also saw little horns growing out of her head.

Danny felt a light blush come to his face.

"Beautiful..." Danny thought, his eyes still on her...until he realized that this girl is not human.

"Hello, sorry to keep you waiting ! I'm your opponent, Lum..." The green haired girl said, showing off a pretty but fanged tooth smile.

Danny blinked, snapping out of the daze he briefly found himself in.

"A GIRL?!..." Sam exclaimed in shock.

She isn't the only one. Danny, now that the shock wore off, sent her a frown since she is the one he has to face in battle. He doesn't trust this, if it was with the big guy, he could see some logic, but this girl looks harmless.

That made her suspicious to Danny, since he knew from this past year of being Danny Phantom, that nothing is ever as simple as it appears to be.

"You're my opponent?!..."Danny questioned and the girl nodded.

"What's the catch?..." He said as he turned to Invader, who just chuckled again, making him look less scary than he did earlier.

"This is my daughter, Lum… if you can grab her horns in a game of tag within ten days, you win..." Invader said.

"Tag?..." Jazz questioned, surprised that would be the kind of challenge that would decide the fate of the earth.

"We found that it was the duel that would lead to the least amount of bloodshed..." Invader admitted.

"So, all Danny has to do is grab her horns tomorrow, and he wins?..." Tucker asked, looking lost.

"Yes..." Invader said.

"Don't get cocky, I am not easy to catch..."Lum said simply and Danny sent her a suspicious look.

"You still didn't answer my question, IS there anything that is not allowed?..."Danny asked.

"You are an inquisitive one...I like that in an opponent..." Lum said in an almost teasing sort of way.

"The only rule is that neither is allowed to kill each other during the competition, other than that, anything goes..." Invader admitted and Danny sighed.

"I guess I don't really have a choice here… okay, I'll duel your daughter but you guys better keep your end of the bargain if I win... " Danny said seriously while his parents looked worried.

The old guy grabbed his hand and was on his knees, looking relieved.

"Thank you, son...you are doing a great, heroic service for your planet..." The old guy said.

"Well, that's that..." Invader said simply.

Later

After everything was settled, a bunch of reporters came in to ask Danny questions about what he just agreed to and Danny hated this more and more.

But like he said earlier, he has no choice.

Once they finished, Invader told him that the first day of the duel will be tomorrow, first thing in the morning, in the middle of the town, so he better get plenty of rest...However, before he and his daughter left, Lum actually walked up to Danny, who is still glaring at her, not trusting her at all.

"What do you want?..." Danny demanded, and Lum just giggled a little.

It made this even weirder, especially the way she smiled at him...It's way too innocent to belong to a world conquering alien. He doesn't trust it, he knew from personal experience that things aren't always as they appear to be.

The alien girl just kept smiling that way, as if nothing was wrong in this situation.

"I would like you wish you luck for tomorrow… you are going to need it..." Lum said in a strange, almost notorious way before she left with her father to go to their spaceship.

"Why am I getting a bad feeling about this?..."Danny thought as he frowned hard as he watched her leave.

Just then, his sister and friends approached him, since they didn't get a chance to do to all the reporters who kept pestering him until his folks managed to send them away.

"Danny, are you really going to chase after her tomorrow?..." Jazz asked in worry.

"You heard them, I don't have a choice...it's either grab her horns or we will have to rename the earth to Invader-ville..." Danny said.

"I don't like this Danny, this sounds way too simple...and I don't trust that Lum girl..." Sam said in a naturally suspicious tone of voice.

"I don't either, so tomorrow, we have to be prepared for anything..." Danny said, while his friends and sister nodded.

Danny soon left for his bedroom, determined to get all the sleep that he can get for his duel tomorrow.

He knows that he is going to need it.

Lum seems too innocent but he knows that you can't be fooled by an opponent's looks, she has something planned for tomorrow… well, Danny is just going to have to figure something out.

"I hope..."He thought, feeling nervous for tomorrow.

Meanwhile

On the ship, Lum and her father discuss their plan.

"So, what is your plan, daughter?..." Mr. Invader asked.

"I'll just roam his residence known as Amity Park..." Lum said. "I plan to win and get to know this planet pretty well..."She added.

As she says this, she thinks back to the human. This "Danny Fenton" who she will compete against.

She finds him rather cute but that doesn't mean she plans to go easy on him tomorrow.

Hardly.

"Don't get carried away, daughter. This planet has ghosts..." He warned her.

"Ghosts, father?..." She asked, confused.

Her father nodded.

"Yes. Someone known as Danny Phantom acting as a sort of protector for the humans. As far as we can tell, he spends most of his time in the city your challenger is from. This Danny is not that one, so you needn't worry about any superpowers during battle..."He said before smirking. "And after we conquer this world, I was thinking of adding him to our army. We could definitely use someone like him..."He said while his daughter nodded.

"I see...what does he look like?..."Lum asked, being curious.

"From what I have gathered, he has white haired and dresses in black and silver clothes. He can also fly, so it shouldn't be too hard finding someone like him among the humans.."He said.

Lum nodded before she went back to her room on the ship, wanting to get plenty of rest for tomorrow.

She was really looking forward to this battle.
