After Phantom Planet. But AU where the disasteroid wasn't made out of ectoranium.
Jack was in a damp, dimly lit room. It was cold and made out of stone. Hardly anyone came here to visit him, as were the rulers demands. Though, the occasional ghost came and gave him food and water.
Jack kind of wished he'd never shot at these ghosts in his life.
One visitor he never got the chance to have was Phantom. For all his good deeds he claimed to be doing, he never tried to free Jack or even came to visit him. Jack wondered what had happened to Phantom. After all, he and Plasmius had never been on the best of terms.
Jack was tethered to the wall with chains that had a faint glow to them. He suspected that they had some kind of anti-ghost serum on them, otherwise the ghosts could have tried to free him by now.
Maybe that's why Phantom hadn't come yet, because he knew he couldn't free Jack.
Jack's head slid back and thumped against the cold stone.
He still didn't understand how Vlad could take the world hostage the way he did. He was such a free spirit and easy going guy in college, outside of their field of study that is.
They had all been best friends in college. How couldn't he have seen that one of his best friends had changed so drastically? Especially after not seeing him for twenty years?
Maybe he had just wanted to deny the reality that had been placed before him. Staying loyal to someone who no longer deserved it or who would even return the favor.
Maddie must of seen it. She was always the more observant of the two. So why didn't she say anything to him?
Jack hung his head, holding it in his hands.
There was no use thinking about the past now. Everything was already said and done. Vlad was ruler and he stole Maddie and their kids. Humans and ghosts alike feared him.
Sometimes Jack would get news on the world above him. Good, bad. What was happening. How his family was doing. One thing he never failed to notice was that the ghosts visiting him never brought any mention of Danny. What had happened to his son? Had something horrible happened to him? Had he taken Vlad's side and the ghosts were angry with him?
No, That wasn't like Danny. Underneath that teenage exterior and falling school grades, Danny always had a drive to do things the right way, even if it wasn't always easy.
Jack sighed. It felt horrible not knowing what had happened to members of Amity Park. Whether they be ghost or human. He didn't really know how the world was doing while he was locked up in this prison.
Soon, Jack felt the temperature of the room drop farther than it had already been. Looking up, he saw a familiar mop of glowing white hair sticking from the wall of his cell.
It was Phantom.
The ghost boy appeared to have aged in the time that Jack had been here for. His hair was longer and his facial features sharper in contrast to the boyish appearance they once had. He also looked gauntier, as if he hadn't had the chance to eat much lately. This also baffled Jack. Why would a ghost's body deteriorate like that?
"Da- Jack!" Phantom exclaimed. "I found you!"
"Phantom?" Jack replied, still relishing in his disbelief at having the ghost boy in his cell.
"We've got to get you out of here. They're not that far behind me. The alarms went off after I escaped and since I'm not flying away outside they're gonna know where to find me." Phantom said, floating over to Jack to inspect the chains.
Phantom tugged on one of the chains, testing its strength to the wall. He tried shooting blasts at it. The next thing he tried was grabbing Jack and going intangible.
At this, Phantom screamed. He let go of Jack and collapsed on the ground beside him. The chains glow had increased and now gave off a faint heat that seeped into Jack's skin.
"Phantom?" Jack said again. He prodded the boy.
Phantom gave a groan and looked up at Jack.
"I-" Phantom started, but the door to Jack's cell boomed open.
Phantom disappeared, but Jack could feel a hand being place on his foot, a small gesture to let him know he was still there.
Looking up to the door, Jack could see Vlad Plasmius. He was wearing a flaming crown and a look of pure rage. Vlad strode down the stairs to glower down at Jack.
"Jack, my dear old fat friend," Vlad started snidely. "Have you seen that wretch of a being Danny Phantom?"
Jack shook his head. He didn't want Vlad to get his hands back on this boy.
"Oh? But my readings indicate his ecto signature is nearby. And," he gestures to the chains. "Those are telling me a ghost tried to use it's abilities on you.
"So where is he?"
"I don't know, Vlad. Gone. Disappeared. If I were too dangerous for him to be around, why would he still be here?"
Vlad tsked, taking a device out of his cloak. "Jack, you are too oblivious for your own good."
He pressed a button and Phantom's screams filled the air once again. First, his invisibility slipped from his fingers. Then, a white ring began to form around his waist.
Phantom was able to send the ring away, but Vlad increased the power on the device forcing it back. The rings traveled along Phantom's body, revealing a very familiar boy.
Laying on the ground before Jack in Phantom's place was his son Danny, writhing in pain.
"What did you do to him?" Jack bellowed at Vlad.
"Do you like my invention, Jack? I programmed it with Daniel's ecto signature so that, instead of harming every ghost within its radius, it would only affect him.
"And I don't think you should be asking what I did to him. It should be what you did to him. Your bumbling created not one, but two human-ghost hybrids."
Vlad picked Danny up and strode back to the entrance, ignoring Jack's screams to let him speak to his son.
Soon, the door banged shut and Jack knew that his last chance of escape died that day.
