A/N: Hey guys! It's Sakra again. So lately, I've been on a writing craze. I've been writing most of the time lately. So, when I was poking around the archives of Danny Phantom crossovers, I spotted Percy Jackson. I was like, "Ooh!" so I looked into it, expecting to see a lot of stuff with Nico in it, considering he's the Ghost King. I was shocked to find nothing of the sort. I decided to fix that. Don't you agree? So, this is Operation: Ghost King. The case is displayed. The characters are in place. Now it's time to execute the mission. Let's roll, agents.

Ghost Zone, Skulker's Lair, 07:29

"Let me go!" Nico di Angelo screeched, struggling against the glowing, radioactive-green ropes that bound him as he sat at the base of a broken pillar. He wasn't angry—oh, he was far from angry. He was seething with unadulterated fury. How dare he? How dare this poor, ugly excuse for a ghost kidnap him, the Ghost King, from Camp Half-Blood? He tried to will the shadows to attack savagely, or at least allow him to slip away. The shadows, strangely, didn't bend to his will as much in this odd world. They flipped upwards a little, but refused to move.

"Now why would I do that when I already went through the trouble of capturing you?" his captor questioned, rubbing his cheek where Nico had punched him hard.

"Who are you and why did you capture me?" Nico demanded through gritted teeth. "Do you know who you just captured?"

"Of course I know," the ghost said, sounding very annoyed and offended. "Every ghost in the Ghost Zone knows of you, Son of Hades. I am the hunter of ghosts, the best hunter in the Ghost Zone! I am Skulker!" He laughed manically. Nico cocked an eyebrow, questioning this guy's sanity.

"Now…" Skulker typed something on his computer. "Let's just check into the Underworld and see what your old man has to say…"

"Oh, so you want to be sent to the Fields of Punishment?" Nico asked. "'Cause that can be arranged."

"No," Skulker disagreed. "Your father has no power here in the Ghost Zone. He may have created it, but with the mass amount of strange ghost with powers, like myself, he can't really control us. So, the ghosts here can come and go as we please…at least, we used to before that wretched ghost child showed up…" He pounded his fists against the computer before typing again. "Just a few codes here…few numbers here…and…viola!" The scowling face of his father showed up.

"What do you want now, Skulker?" Hades questioned. "I already told you; the halfa is your problem."

Halfa? Nico thought. What's that?

"I have a deal for you, Hades," Skulker said smoothly. "I have something that you want—no, need, and I do want something in return."

"Whatever you have, I don't want it."

"Oh? Are you sure?" Skulker turned around and walked towards Nico. His eyes widened in realization.

Oh no…he's not really thinking…how stupid…?

Skulker picked up the struggling Nico by the ropes and held him in front of the screen.

"Nico?" Hades called.

"Dad!" Nico called back. "I literally can't get these ropes undone!"

"Of course not," Skulker said. "These ropes are meant to repel ghosts; I'm sure they hold a demigod son of the Lord of the Dead just fine." He set Nico down. "Now, I'm sure that you want your son, correct?"

"Give me back my son," Hades seethed in a dangerously low voice, "or I will send you to the deepest pit of Tartarus, so help me…!"

"I'll take that as a 'yes'," Skulker told him, sounding pleased. "Now, I'm sure, your only demigod son…he'll be worth a lot."

"You will not use my son as a bargaining chip!" Hades roared. Nico looked surprised.

Does he…actually care? He actually cares?

"But I believe he is in my possession now?" Skulker began.

"I don't belong to you!" Nico shouted, but Skulker kicked him.

"Keep in mind, Hades, the child is with me now; maybe I'll give him a haircut…starting just below the chin." Hades growled menacingly. His black eyes glittered with murderous intent.

"…fine. How much to you want from me?"

"Dad, don't!" Nico shouted, getting kicked again.

"How about…oh, I don't know…twelve million drachma?"

"What do you want Greek money for, anyway?" Nico questioned, his answer being another kick to the ribcage.

"…ten million or no deal," Hades grumbled. Nico looked up in surprise. His father was proud of his riches; he would spend a good chunk of it on him? The one who Hades always claimed was the lesser of him and his sister?

"Deal," Skulker said, closing the deal. "Meet me on the outskirts of Amity Park in two hours. Bring no one but yourself."

"Bring my son unharmed, or you will pay the consequences," Hades warned before cancelling the call. Skulker began to laugh.

"Come along, you puny child," he said, picking up Nico by the back of the ropes. "It's time we go see your daddy."

A/N Okay, so Nico's in trouble, Hades is ticked, and Skulker? He's, well, being Skulker. Also, I put an Outsiders reference in there. Ten points to Gryffindor (or whatever your preferred House is) if you spotted it correctly. Don't forget to review~!
