Chapter One: Phantoms and Portals

Location: Amity Park

Date: September 3rd

Time: 1755 EST

"Just give it up Ghost Child for I, Technus, master of all things technology and with my new and improved form and gadgets, will defeat you once and for all! I will finally get the respect I deserve!"

Floating in front of this ghost called Technus with a bored expression and arms crossed, the self-proclaimed hero and resident ghost of Amity Park Danny Phantom raised an eyebrow in response. "Really Technus, that's fascinating. Has anyone ever told you that you should consider a career in writing fiction? Just save yourself the embarrassment of being beaten by me again and just get in the thermos."

"I will do no such thing! I, Technus, shall never be captured by such a prehistoric containment device! Allow me to show you what I mean. Ha ha!" Technus directed an attack towards Danny that consisted of various computer-related electronics. Sighing, Danny turned intangible and allowed the gadgets to just harmlessly pass right through him.

Below the two 'fighting' ghosts, Danny's two best friends Sam and Tucker were watching with the same bored expression as their ghostly friend. "Technus just never learns does he?" Tucker mentioned to Sam while still watching the fight, who replied with a simple and bored "Nope", popping the 'p'. They barely reacted or even blinked when Danny shot an ecto-blast at Technus' head and proceeded to suck him into the Fenton Thermos.

Returning to his friends on the ground, Danny looked really bored and annoyed with his situation as of late. "Ugh! I have been fighting ghosts non-stop for the past two days and I'm losing valuable study time! And for what?! To throw a single punch or ecto-blast at whoever I'm fighting and have them easily sucked into the Fenton Thermos? This is getting me nowhere and is a waste of my time…"

Sam looked at Danny and motioned to the Thermos in his hand. "What I don't understand is why they think coming back to fight you is going to accomplish anything. You obviously defeat them quickly and with little effort anymore. What's the point?"

"Yeah dude, they don't even compare to you anymore and don't even provide a real threat or challenge like they use to. Only thing they got going for them is their annoyance and persistence. But mostly annoyance…"

"Well if you want a challenge that badly Daniel, then allow me to liven things up for you."

The three teens immediately recognized that voice and quickly looked around to see if they could spot the new spectral intruder. When Danny spotted him floating above the Nasty Burger, the local teen hangout, he turned his green-eyed glare toward his arch nemesis. "Plasmius" He growled. "What do you want this time fruit-loop? In case the first dozen times weren't enough to get it through your thick skull, let me say it again: You are NOT going to kill my dad, you are NOT going to marry my mom, and you are NOT going to suddenly get me as the 'perfect half-ghost son/apprentice' you have always wanted. So whatever you are planning to try to change those facts, you might as well forget about it and go back to being a lonely rich man who seriously needs a cat."

"Oh but there's where you're wrong Daniel."

Danny looked surprised at the older ghost. "You actually got a cat?"

"Let me guess, you named her Maddie." Sam stated, her tone dripping with sarcasm, only to be completely grossed out when Plasmius grinned back. "Oh, gross!"

"Dude, you are one seriously crazed up fruitloop."

"What I was actually going to say was that I do have a plan to change those 'facts' of yours young Daniel." Plasmius said with an evil grin. "And to make things even better, you won't be around to do anything about it! Behold, the tool to end your constant meddling in my plans." Plasmius then pulled out what looked to be an old scroll of some sort, but Danny instantly recognized it, and laughed.

"You're joking right? The Infi-map? I don't know how you got it from Frostbite without his permission, but that's not a weapon." Danny said as he continued to chuckle, his friends also getting a laugh from the scene. "I have to admit Plasmius, you look really funny pointing a map at me! Hahahahahaha!"

But then Plasmius done something that caught Danny off guard; he grinned.

"I'm sorry my boy, but there is more than one map, and it seems that the owner of said other map never told you everything it is capable of." This caused Danny to blink twice before he resumed his previous glare towards the older Halfa. "You see Daniel, the Infi-map can do much more than bring a person to another time period or realm," he smiled wickedly at the next part, "it can also teleport someone to another dimension. Oh and here's the kicker, you won't be able to escape unless it was asked to the map that was used specifically on you." Danny's, Tucker's and Sam's eyes grew wide in disbelief with this turn of events. "In other words child, you can't return unless I wish it! Or someone manages to get possession of my Infi-map and ask it to bring you back."

Danny's eyes were wide in horror. He started involuntarily stepping backwards with his hands raised defensively saying "No! Wait! You can't do this! Vlad!" Plasmius grinned and then aimed the glowing scroll at the scared ghost child. "Infi-Map! Send Danny Phantom to a different dimension!"And with a pink beam of light and a frightened scream from Danny later, there was silence.

And the ghost boy was nowhere in sight.

Location: Mount Justice

Date: September 3rd

Time: 1822 EST

The team has just finished their meal graciously provided by the resident Martian, M'gann. Even though she was still getting used to Earth dishes, she was a surprisingly good cook. Not that it mattered to Wally, he would eat anything she made, saying it was because of his 'high metabolism due to being able to run up to a few mph shy of the speed of sound', when everyone knew it was really his way of trying to get on her good side.

After observing the time and realizing that it was after 6pm, the team leader Aqualad made sure he took the time to remind his team of a certain appointment. "Is everybody ready?" After quickly looking to his teammates, which included Robin, Kid Flash, Artemis, Superboy, and Miss Martian, and seeing them all waiting in their hero outfits he nodded and proceeded. "Good. We shall train amongst ourselves until 1930hrs before taking a small break as Black Canary will be here at 2030hrs for our training session, and we must not keep our instructor waiting."

As the team began to head toward the training platform, their attention returned to the living room they just left as a bright green light lit up the entire room. After staring at the swirling green light that appeared out of nowhere for a few seconds, Kid Flash asked the obvious question: "Uh guys, what is that?" As soon as the words left his mouth, the caves computer announced an alert.

"Warning. Warning. Unknown energy impulse detected. Sealing all exits and shutting down all zeta-tube transportation."

The young heroes positioned themselves in a battle ready stance, waiting for something to emerge through that green light, although nothing could prepare them for what came next.

They all tensed as they saw a body emerge from the unusual light. But this body didn't attack as they had originally suspected, instead it just fell straight down until it hit with a loud crash on the teams' living room coffee table causing dust and debris to go everywhere.

The team just stared at the scene with wide unbelieving eyes, with only Robin rushing forward to investigate further. What he saw was a teen not much older than himself, wearing what looked to be a black and white HAZMAT suit with white gloves, boots and belt. And is that a thermos attached to his belt? But what really got Robin's attention about the teen's appearance was the fact that he had pure white hair, and his body seemed to glow slightly. Realizing the boy wasn't moving, Robin placed two fingers from his black gloved hand over his carotid artery to feel for a pulse.

There was none.

Robin quickly turned to face his still stunned teammates. "Guys! He doesn't have a pulse! Someone come give me a hand!"

Kid Flash was the first to snap out of his daze, running over to where his friend and the unknown teen were. Kneeling down and quickly looking over the condition of the boy, he raised a questioning eyebrow to the Boy Wonder. "You sure he has no pulse Rob?"

"Yes I'm sure! Why?" Robin replied to the speedster.

"Because it looks to me like he is breathing…" KF stated as he pointed at the unconscious teen's chest. Robin looked down to observe his chest, only to become wide-eyed once he saw the rise and fall that indicated breathing, and life. It was slow, very slow, but there. Robin quickly re-checked his carotid pulse, only to yield the same result as before, and proceeded to check every other site he knew of for a pulse.

Robin sat back and looked at the teen with wide eyes and mouth hung open. This shouldn't be possible! How can someone not have a heartbeat but still be breathing? It's not something he came across before, and he worked with Batman!

By now the rest of the team had made their way over to the scene. After seeing the looks on both Robin's and KF's faces, Artemis asked "What's going on? What's wrong?"

Kid Flash continued to stare, but responded to the question as best as he could in his state with a simple "W-w-we don't k-know…" Wally is a man of science, and he was trying to figure out how this whole scenario was scientifically possible. As far as he knew, it wasn't.

"What do you mean? What happened to get you two all worked up like this?" M'gann asked, trying to get more information from the two boys.

Robin looked to the team with an expression like they have never seen before. "I've never seen anything like this before. H-he has no pulse, but yet he's breathing…"

The whole team now had the same expression on their faces as Robin and Kid Flash did. How was this possible? What do they do now? Does that mean the kid is still alive, or not?

As ashamed as they may be to admit it, they were all too shocked to do anything. For what seemed like an eternity, not one person moved.

Thanks for reading! I hope you enjoyed the first chapter and I shall try my best to update soon. I may even try to update once weekly! :)
