Chapter 1

Author's Note

This is a crossover between Young Justice and Danny Phantom. This story will take place a week after Young Justice season 1 and almost immediately before the finale (Phantom Planet) of Danny Phantom.

The slight change I've make to the Danny Phantom timeline is that Danny doesn't reveal his identity to his whole town, only to his family. Nor did statues get put up all over the world for Danny's heroism. No one knows his identity with the exception of his mom, dad, Jazz, Tucker, and Sam. I'm also going to leave out the part where Vlad Masters / Plasmius reveals his identity. Other than that, I'm going to start playing with the 5 years of Young Justice that were skipped over and dive straight into the idea of a world where both Danny Phantom and the D.C. world exist. I'm not planning on nerfing Danny's powers, but I might do something along the lines of Danny having trouble figuring out his ice powers.

I don't own Danny Phantom, Young Justice, or any characters associated with either of these TV shows. Nor do I own any of the D.C. universe characters.

UPDATE

I did some serious updating to the beginning of this chapter due to the lack of tension and story plot entrance. I just added on to the beginning more than anything else. It's still the same general basic story idea. I wanted the characters to be more involved with what was happening.

(I'm going to try to explain this without giving away the plot.) When I started writing this, I knew my character's 'how' in the story. I had not yet come up with a good and solid 'why' in terms of a good story plot. That's why some things have changes, because I finally have a good motivation for my characters (and my villains).

Thank you so much for the tips and advice!

Some Location, January 7, 11:50 am

Miss Martian had just slammed Psimon between two pieces of the rubble from a building. Superboy was in hand-to-hand combat against Bane, while Artemis shot arrows trying to disrupt his energy source.

"Good work, team. Keep them distracted." Aqualad said over the telepathic link.

"I still need a couple of minutes," Robin dropped off his third bomb. He had three more bombs left to put in place before he could start the timer. He set his fourth bomb in a groove in the building and rolled out of the way of a flying pieces of debris.

The previous week before, Vandal Savage had managed to get the majority of the Justice League under the influence of his Starro-tech. The building Robin was in process of blowing up contained a lab with parts and pieces of the nanotech that had contributed to Starro-tech's existence.

Zatanna, Rocket, and Kid Flash were in a similar situation in a different part of the globe. Even the Justice League was under pressure. Two of earth's Green Lanterns, Superman, and Martian Manhunter were off in space trying to figure out what the six main members of the league had done during their 16 missing hours. Fate was away hunting down Klarion and Vandal. This left the Young Justice team to finish off what was left of the nanotech and the people behind its creation.

Robin heard another explosion. The new smell of smoke burned his lungs. He set the fifth bomb in place and ran out. He immediately jumped out of the way of Bane. Superboy launched himself at the big brute, and Artemis was somehow able to get a clear shot between the dust and the smoke. Bane collapsed and began shrinking into a somewhat normal size.

Somewhere between all of that, Artemis ended up beside Robin. "That was fun," Artemis said as she pulled out another arrow, this time aiming for Psimon.

"I've got one more bomb to place. Make sure his attention is on you and not me." Robin covered his head with his cape as Artemis released an explosive arrow.

Robin caught her words as he ran off. "Whatever you say."

He went around the building to the last place he needed to set a bomb. The bomb was placed gently into a natural groove in the wall. Robin noticed the noise of fighting dull as his comm blared on. He raised his hand to the piece of metal in his ear.

"Abort mission," Batman's voice rang through his head.

"What?" Batman! We're almost done!" Robin didn't understand. One more bomb and one more bad guy to snag!

"We don't have time. Blow up what's there and meet at Mount Justice." The comm died out. Whatever it was, it was more than urgent.

"You heard him. Let's move." Aqualad's thoughts swept through Robin's.

"I'm getting the bio-ship ready." Miss Martian flew to the red ship that had just become visible.

Robin stood at the entrance of the bio-ship, waiting until the rest of the team had made it in. He pulled up his holographic screen from his wrist and began a thirty second countdown for the bombs. They had to leave Bane too. At least he would be out of the way of the explosion.

"Where are you all going in such a rush?" Psimon appeared in front of Robin. "Psimon says…"

Robin threw a series of explosives in Psimon's direction. "Sorry, but we don't have time for a game of Psimon says." The thirty second countdown ended, giving Psimon a distraction and Robin a chance to get into the bio-ship. He pulled himself into a chair and the team briskly made their way to their headquarters.

…

Mount Justice, January 7, 11:57 am

Robin was surprised to find Kid Flash, Zatanna, and Rocket waiting for them. Batman pulled them from their mission too? What was going on?

"We have an asteroid that is going to crash into the earth in fifteen minutes." Batman explained the situation quickly. "Our Watchtower sensors are malfunctioning and the weapons are still being repaired. We suspect Savage disrupted the weapons before he left. The sensors on the other hand should have warned us about the asteroid hours ago, but that's beside the point. Superboy, Miss Martian, Zatanna, and Rocket, I want you to Zeta-beam to the Watchtower and see if you can do anything to help slow the asteroid down or stop it. The Zeta Tubes are working at the moment. Wonder Woman knows that you are on your way. You will be taking orders from her."

They rushed out in silence. Like Robin, they were probably too shocked to say anything. Robin heard the Zeta Tube announce them as they left.

"The rest of you, I want you to calm the populace as best you can. All our heroes are working on the problem, while the people are growing chaotic."

"And since we don't have anything to contribute to this problem we're the best people for the 'calming the people' job." Artemis grumbled. Robin gave her a scowl. It wasn't like they could do anything that would actually affect the asteroid. All they were doing now was wasting Batman's time.

"Understood," Robin said.

"We will do the best we can." Aqualad concluded.

Artemis' huff wasn't pure joy or anything, but it was the closest they were going to get from her in terms of an acknowledgement.

Kid Flash whizzed past Robin. "I'll take Metropolis!" He volunteered. "You know, since they are usually hit by a ton of Superman's enemies, and he's not exactly here at the moment…"

"Just go," Robin said, trying to leave the humor out of his voice. The Zeta Tube announced Kid Flash as he left.

After Aqualad and Artemis had left, Robin stepped into the Zeta Tube. He was surprised to find Batman waiting for him. Batman caught his gaze.

"I'm going to do what I can from the Bat Cave. I'm hoping my weapons from there will be able to have some effect against the asteroid." Batman explained.

Robin nodded in response. With less than ten minutes left, even he was starting to get a feeling of hopelessness.

"Good luck," the mentor told Robin before he teleported.

Robin gave the best – hopefully not last – smile he could. "You too."

Robin was teleported to his school, the closest location he could to Gotham's center. He grabbed his motorcycle that he kept near the school and drove off. As he got closer, through all the smashing of window shops and car doors, he realized that any efforts he was going to put into calming these people would probably be pointless.

And for the first real time, Dick Grayson, the boy behind the mask, got a real glimpse of the asteroid. It was a huge green rock, probably half the size of the moon, but as Robin sat there frozen in horror, all he could notice was how the rock just kept getting bigger. It was one of his two only moments when he realized that the world was actually going to end. The other time had all been in his and his team's heads, but this was all too real.

There was no way the Justice League would be able to destroy the asteroid without any serious damage to earth. That much was certain.

The asteroid was too close to Gotham. If the Justice League did manage to destroy it in the next two minutes, his town would still be in the crossfire.

Dick watched as his entire city became translucent. He watched as he became translucent too. And there was nothing he could do to stop it. Bewildered and confused, he stood frozen as the asteroid, still solid, passed through the concrete of the ground, missing Dick by inches.

"Whoa," a whisper escaped his lips.

The asteroid went under his feet and into the earth. It kept going downwards until it was no longer visible. The ground, buildings, cars, the people and himself began to return to their solid form. Within seconds, everything went back to normal. The robbers didn't notice Robins presence. They looked stunned, as if they were trying to decide if they should continue to rob whatever it was they were robbing or run in fear.

What had just happened? Dick looked back at his gloved hand, no longer see-through like it had been moments before. What had Batman or the Justice League do to make the entire earth intangible?

Dick bolted straight to Wayne Manor from his motorcycle. He made his way to the living area with an old, tall clock. He jabbed at a lever, revealing the entrance to the Bat Cave.

"Bruce!" Dick called out. His voice echoed through the cave. As did the sound of typing.

Batman was hammering away at the keyboard of his computer. Several of his screens had 'Invalid Date' or 'Error' displayed on their monitors. Several more screens had reporters boggled over the sight of a nearly invisible world displayed on the lower portions of their screens.

"Bruce, how did you get the asteroid to pass through the earth like that?" Robin asked, although he knew the answer. With a Batman this frustrated and no actual data being displayed, anyone could guess the answer. It didn't take a genius or detective to figure that Batman didn't have a clue.

Well, to be fair, Batman probably did have a clue. Did he have answers? Probably not.

Batman's eyes were fixated on the monitors. "We didn't. With the immediate danger of the asteroid now over, I'm trying to figure out why our sensors didn't detect the asteroid sooner and why the earth became intangible." Batman explained through gritted teeth.

"With no luck, it looks like." Dick muttered.

"More luck than you'd think." Batman gave no outward hint to what he was alluding to. "Dick, could you take patrolling Gotham alone tomorrow night? I just got a plausible lead. If you need back-up, Batgirl is beginning to hold her own."

"Yeah, I'm cool with that." Dick replied. He wanted to know what he was up to, but if Batman didn't offer the information, then trying to get it was pointless. That was probably the most bizarre, terrifying, and odd twenty minutes of his life. Could he handle a night of normal patrol? Yes.

Amity Park, January 8, 5:25 pm

"So, your parents really are cool with you being Danny Phantom?" Tucker asked, his thumbs rigorously banging away on the buttons of his controller.

"Yeah, I think so. Jazz told them when they thought I had died, so they seemed happy with the fact that I was at least half alive." Danny's avatar was hammering away at Tucker's avatar, although they were both desperately trying to avoid Sam's.

"Man, at least you don't have to keep secrets from your parents anymore!" Tucker yelped as Sam's avatar obliviated both Tucker and Danny.

"Yes!" Sam cheered.

Danny set his controller down. "Yeah, but it's kinda weird. I mean, can you see my dad letting me just fight my own battles? He's going to do what Jazz originally did and I am going to get accidentally sucked into the Fenton Thermos."

"At least we'll know how to get you out." Sam offered.

"Yay," Danny muttered unenthusiastically.

"It'll be fine. And for now, we don't even have to worry about Plasmius. He's stuck on a space rock." Tucker gleamed.

"Yeah, for how long though?" Danny voiced his concern.

Sam set her controller down and stood up. "Does it really matter? Just enjoy your day of rest. Come on, you haven't seen your statue up close yet." She said as she offered her hand.

"Yeah, that's right!" Tucker exclaimed.

Sam was right, and Danny knew that the other ghosts wouldn't be after him for at least a day. He just saved both their worlds, that should've earned him some points, right? He took Sam's hand and headed to the new statue of his alter-ego.

Vlad Master's Mansion, January 8, 11:30 pm

Flying back to earth as quickly as he did had had drained Plasmius of quite a bit of energy. Yet he kept his ghost form up. He was furious. Furious at himself for screwing up so badly. Furious at being left out in space. And on top of it all, furious at Danny Phantom for fixing his mess for him.

Plasmius turned at the sound of a shattering window.

"What have you been doing to the Justice League satellite?" A giant bat growled. The new voice's movements were shielded by the night. When Vlad didn't answer, Batman continued on. "Why was the asteroid plummeting towards earth, why were you hiding Amity Park, why did the earth turn intangible!"

Plasmius was flung back against the wall and held there by batarangs. He knew the Batman on a normal day would be easy enough to handle, but in his moment off exhaustion he knew that the best strategy would be to retreat.

"Batman. I've heard so much about you. But frankly, I'm not in the mood to answer your questions nor am I in the mood to play around with you." Plasmius held up his signature smirk and let himself turn intangible. The batarangs clattered on the ground.

"I never said you had a choice." Batman sneered. He flung tiny green orbs in Vlad's direction. Plasmius eyed them suspiciously, when they suddenly lit up and sent currents of electricity through his body. When the voltage cut out, Plasmius resumed his smirk and kept up his outward cockiness.

"I'll see you again. But now, well, we can't be having an unfair fight, can we?"

With that, Plasmius shot a green ray in Batman's direction. He let himself turn invisible and flew straight down into his underground lair. Rings appeared around his waist and split, one upward and one downward. Vlad Masters let his exhaustion sink in.

"I can't believe that me flying back to earth is what finally tipped the Justice League of my tampering." He muttered angrily under his breathe. "I've been able to go about my own business for twenty years. No suspicion, no intervention." He walked to his surveillance monitors. The Batman was nowhere to be seen.

"Typical." Vlad said. "The Batman has left. Or he's hiding. Either way I don't feel like going back up to check." If all else were to fail, Vlad Masters knew he could hop into his ghost portal. Batman would be an idiot to follow him in there.

"Would you like me to get you a cup of tea?" A holographic Maddie Fenton asked.

"Ah, tea would be lovely, Maddie dear." He took the cup.

Even though he was mad at himself, Vlad was mad at Danny for inherently bringing all the attention. The way he had solved the problem would turn the heads of everyone to their town.

Now that the League knew about him, or at least Batman did, there would be no more reason to mask Amity Park from prying eyes. Being able to slip into computers as a ghost had its advantages, but his over eagerness for quick money had evaporated his chance of hiding the city full of ghosts. And this would only turn more attention to his alter-ego, Vlad Plasmius. Even he couldn't stop the inevitable. Batman was going to discover the town of ghosts, and soon. He was still mayor, but his town was going to get a lot of prying eyes.

Vlad suddenly had an idea.

...

Mount Justice, January 9, 12:00 pm

The team waited the arrival of Batman. He had said he had a mission for all of them, and now they simply waited for him to show up with their assignments.

Kid Flash finally arrived, late, and zoomed into the room. "What is she doing here?" Kid Flash asked as he pointed to their 'honorary member' Batgirl.

"For whatever reason, she's needed for the mission." Robin said laxly. He sat on the sofa with his hands behind his head and his feet up on the table. "If you would have showed up on time, you would've known this." It was so much fun, being snarky.

"That's cool. We've needed more girls for a while." Artemis grinned as she walked in, late as well. No one was able to question her lateness because, moments after, the overhead speakers spoke up.

Batman 02

The Zeta Tube's announcement was welcomed. The team jumped to their feet and followed Batman to the briefing room.

"After yesterday's unusual almost-catastrophe, I have four missions for you, and as such you will be divided into teams." Batman began.

"Man, he doesn't waste any time with these mission briefings, does he?" Wally whispered to Robin.

"Dude, just be quiet!" Robin hissed back.

"An as you all know, last week, six Justice League members disappeared. On account of that, you all did a fantastic job of putting the people responsible back in their place. Artemis, Rocket." The girls perked up as their names were called. "I have a covert mission for you. I want you two to check up on Bialya and confirm that Queen Bee is not there. If you see any labs or suspicious activity, put them in a report. But no intervention.

"Kid Flash and Super Boy, I want you two to check on Belle Reve." Batman handed Kid Flash a piece of paper. "This will allow you two to get in. We want to make sure that everyone that is supposed to be there is actually there. Take Sphere and Wolf if you think it will be necessary." Kid Flash looked too eager for his own good. SB briskly nodded and the boys ran off.

"Aqualad, Batgirl," Batman's attention turned to his newest apprentice and the leader of their team. "I need you two to check on Geneva. It is believed that Killer Frost and one other has made their way over there." Batgirl looked as excited as ever for her first team mission. They walked over to the Zeta Tubes. The three groups had left before Batman continued on to his final mission.

"As for you three." Batman turned to Robin, Miss Martian, and Zatanna. "I have picked this team out specifically for a different kind of mission." He handed Robin a gun with an odd green glow.

"There is a town in Illinois called Amity Park." He watched as Robin's face turned to confusion. "You will not have heard of this town. For some reason, it has been blocked from news channels and well hidden from the Watchtower." He saw Robin's questioning and half-shocked stare. "I am currently looking at why the Watchtower and everything on the internet is going blank when it comes to this town. We believe that Amity Park has something to do with the earth turning intangible. You three are to not engage in anything out of the ordinary."

"Then what is the new weapon for?" Robin asked.

Batman glared, but Robin understood that the glare was not fully directed at him. "Precaution. Hopefully, between Zatanna's magical abilities, Ms. Martian's abilities, and your skill and adaptability with weapons, you'll be able to protect yourself if anything… comes up."

"And you don't exactly know what that is, do you?" Robin realized. It was more as a statement than anything else.

"Just be safe. Remember, this is a covert mission. Don't get involved unless you must. Just collect as much data as you can. Figure out why the town is being virtually hidden and if it is related to the intangibility fiasco." Batman added.

"Is there a zeta tube to this Amity Park?" Miss Martian asked.

"No. You will be taking the bio-ship. Its camouflage will allow you to prolong your stay if you must." The three nodded briskly and ran off to the bio-ship.

"Oh, and one more thing. The bio-ship won't be able to find Amity Park either. I recommend setting a course for Naperville, Illinois. That seems to be the closest reading I could get to Amity Park."

"Understood." Zatanna said.

The three piled into the bio-ship. "I wonder what we're going to find." Robin said out of curiosity. "This is an unusual team if it was handpicked for this mission."

"Who knows. This is Batman we're talking about, isn't it?" Zatanna said.

"Yes, and for Batman to have this little data on a town and its situation is beyond unusual." Robin's body began to vibrate as the ship took off.

"We'll find out what's going on soon enough." Miss Martian's eyes glowed green as she linked herself to her bio-ship. "Course set for Naperville, Illinois."
