Hi everyone. I'm very, very, VERY sorry about the late update! :(
I just never got around to uploading this, because whenever I had time available I would always end up being occupied with something else. But oh well, that's how summers always are...

So far I've gotten only two reviews for this story. Then again, that's because no one really checks these kinds of crossovers, even though I think these series were literally written for each other. But I'm still happy for even getting reviews in the first place! So I thank AlphaFive and gilly boy for reviewing :3

I would like to give credit to a fellow author named hollyivy7 because this chapter based on the first chapter of her fanfic called "Battle of the Brainiacs".

Basically, the first chapter was Artemis's side of the story. Now you get to see what's up at H.I.V.E. :)

EDIT (8/4/14): I have removed the excerpt of Xiu Mei's letter for fear that I may get in trouble for copyright infringement. If you'd like to know exactly how the letter goes, try to get ahold of a copy of The Overlord Protocol. Or...maybe you could find it online. Who knows what you can find on the internet these days?

Dr. Nero was sitting at his office desk. The bell had just rang and school had just ended at H.I.V.E. But even though the students were off for Christmas break now, he certainly didn't feel any different, nor relieved. In fact, he was probably more stressed out than usual at the moment. I should be happy that Christmas is coming around... he thought. But I'm not...why is that?

Nero looked around his office to see if anything could cheer him up. His eyes settled on the fireplace. Normally, a fireplace wouldn't exactly be something you'd want to stare at for hours on end, but it did give you some warmth. In Nero's case, it also gave him great sadness, because within the walls above the fireplace lay a memory of one person he was particularly fond of: Xiu Mei Chen.

He gazed at the ancient map that was hung above the fireplace and sighed. Nero stood up, walked over to it, and pressed a hidden button. The map swung sideways to reveal the door to a small safe. The camera on the safe scanned his retina and the safe slowly flew open. Inside was a letter from Xiu Mei, which Nero cherished a lot.

He took the envelope and opened it. Nero then took out the paper enclosed and read it over again for the umpteenth time. He couldn't help but shed a tear as he read the letter. Every time he read it, it always made him sad. If only you were still alive, he thought sadly. So many things have happened since you left...

He was so absorbed in his thoughts that he didn't hear the entry chime ring. He only got up from his seat when he heard banging on the door, and opened it to see Raven.

"Ah, hello Raven! Wasn't expecting you to visit at this time," he said sheepishly.

"I know; I never usually never come at this time," Raven replied as she walked inside his office. "But it's because I wanted to talk to you about something." Nero had known that Raven was here for a reason, and if she wanted to talk about something in his office, it usually meant that something was wrong.

"What is it, Natalya?" he asked gently.

"Well..." she said, "I feel like something is wrong. Like we're missing something."

"Or more like a someone," Nero corrected her.

"Someone? What do you mean?"

"I'm pretty sure it's a someone," he assured her, even though he had a frown on his face. Despite the fact that it seemed ridiculous to even himself, Nero had learned long ago to not ignore his instincts. And his instincts were telling him that he was missing someone. Besides Xiu Mei, of course, ever since Cypher had told him the bad news.

"You mean Xiu Mei?" Raven asked gently. Raven was probably the only one in the whole world (besides possibly Cypher) who knew about Nero's feelings towards her.

"Well...yes, of course," Nero admitted, "but I cannot bring her back to life. No, I meant someone else, like a new pupil at H.I.V.E."

How interesting, thought Raven, to think of student intakes when he could be on vacation somewhere! Although I'd wonder who he would put in charge of the school if he actually did go away...

"And who is this someone, you think?" Raven asked.

"Do you remember Artemis Fowl?" Nero replied.

Raven nodded. Artemis Fowl had been one of Nero's top students at H.I.V.E.

"Well, he married several years after he graduated, and he had a son, whom he named after himself. A couple years ago, he was going to Russia to confront the Russian mafia by ship, and no one has ever heard of him since. Everyone assumes that he's dead. And he was actually one of my favorite students too...

"I remember his last words to me," Nero continued. "Artemis promised that if he ever had children, he would personally send them all here. The strange thing is that he has a son old enough to attend H.I.V.E., but he is not currently here."

"So that means you want to retrieve Artemis's son during the winter holidays," Raven realized.

Nero laughed. "I know it seems most unusual, Natalya, but there's no other perfect time for this. If I remember correctly, the boy's name is also Artemis. The reason why I chose now is because we can get out of H.I.V.E. without any suspicions. Besides, I'm pretty sure his son has inherited his father's criminal mind."

"But I don't understand, Max. How could he be the son of a famous criminal and yet not be already attending H.I.V.E.?"

"That's the problem. No one knows why, and nobody ever bothered to look into the case. Ever since the father disappeared, the Fowl family has been put off the radar. But whatever the reason, the boy is not here. So we must form a plan to retrieve him."

"I remember the days when his father was very famous. Many villains looked up to him as the greatest criminal mastermind of the 20th century. It was even rumored that Number One secretly admired him..." Raven thought out loud.

"I agree," Nero replied. "But everything changed after that incident."

Raven shuddered at the memories that had occurred after Artemis Fowl I went missing. The Overlord project that had not ended very well, the attacks from H.O.P.E., the U.S. terrorist attack on 9/11, and the constant threat of world domination by an artificial intelligence.

"That is true, Max. You know what I've been thinking about lately? I've been thinking about how Furan managed to emerge out of the blue. I can't believe he's still around after all these years! I thought he'd be retired by now. Furan's in his 50s, for Pete's sake. Why did he even join the Disciples anyway...?"

While Raven was talking, Nero suddenly remembered that the Fowls were also associated with a famous family: the Butlers. He recalled that they were a line of bodyguards and that the one he had encountered was simply known as Butler, although Nero had remembered his real name was Domovoi. Hmm, maybe we could somehow get him to come here too, although not as a student. Nero laughed at his own thought.

"...if only I killed him a long time ago," Raven finished. She then looked at Nero, who was clearly not paying attention to her. "Hello?" she asked, waving her hand in his face. "Earth to Max!"

"Sorry," he apologized as he shook his head free of his thoughts. "I was just thinking to myself."

"Anyway, I think we should find his son's records," Raven suggested. "He may be the son of a famous criminal, but he could just be another Nigel."

"Don't count your chickens before they hatch, Natalya," Nero warned. "Artemis's son could grow up to be the best criminal on the planet."

He opened his laptop and turned it on. Then he accessed the internet and managed to find Artemis Fowl II's profile. Nero opened the file and it began loading in front of him.

"So, what does it say?" asked Raven as it was almost done loading.

A few moments later, Nero merely said, "Read for yourself," and he moved aside so Raven could see the screen.

"Artemis Fowl is publicly known as a 13-year-old genius. He has the highest IQ in all of Europe. In certain circles, however, he is known as a ruthless criminal, willing to do anything for gold," she read.

"So the boy is as talented as his father once was," Nero remarked. "Is there anything else on his profile?"

"Yes, there is an active Interpol file as well," said Raven.

Impressive, Nero thought. What nefarious plan had this boy come up with to have an active Interpol file? But then again, his father was once in charge of a criminal empire that had stretched worldwide. This was why the Fowls were very admired in G.L.O.V.E. and villain history.

"Artemis Fowl II has acquired 12 million pounds in the two years his father was gone," Raven read.

"What? Two years?" asked Nero.

"That's what it says. 12 million pounds is worth a lot. I'm sure Otto and his friends will love him." Raven had a smirk on her face.

"Don't be so sure, Natalya. His father wasn't very friendly at first..."

"Max, don't count your chickens before they hatch...you never know what can happen."

Nero sighed. "On to important matters. See what you can do about the boy, OK?"

"You got it, Max," Raven answered as she started walking out of his office. "But I should warn you: Artemis's bodyguard is one of the 3 best martial artists in the whole world." And with that, she opened the door and walked out.

Nero clenched his teeth. The boy wasn't even here yet, and he was already causing trouble for him. Even worse than Otto and Wing put together, he thought.

"Natalya, you had better find him," he muttered.

Okie dokie...now it's time for feedback. Does anyone in the story seem very OOC (with the exception of Butler, which I sort of did on purpose, but even that has limits)? What can I improve on? What are you expecting to happen next? Review and stay tuned :D
