And now to hear Timepiece's story! By the way, omniscience is the ability to know everything there is to know. And phasmophobia is the fear of ghosts.

I don't own Danny Phantom.

Danny, Danni, Fishtail, Timepiece, and Dora were all sitting in Timepiece's bedroom. Timepiece was sitting on his bed with Dora next to him. Danny was sitting in a beanbag chair and Fish was sitting in the chair for Time's desk. Danni was hovering in the air on her stomach. They were all holding a cup of hot chocolate.

Timepiece glanced at the Dimension Chasers before sighing. "I know from my very, very, very, very, very, ver—"

"We get the point," Danni interrupted.

"—limited amount of omniscience—" He was cut off again by Danni.

"Whoa, whoa, whoa! Hold up! You have omniscience?" the female Phantom said.

Timepiece sighed in annoyance. "Yes. But a very limited amount, like I said earlier. I can't see into time all the time and Master says that it will take me a hundred years before I fully develop omniscience."

"Cool," Danny commented.

The Apprentice of Time gave him a weak smile and continued on with the story. "As I was saying before I was so rudely interrupted—" he glanced at Danni. "—I know that each of you had some degree of an accident with some kind of portal. Danny, your accident turned you into a half-ghost. Same goes for you, Danni. Fishtail, you had an accident with a Merfolk Portal and got turned into a half-merman. Well, I had an accident with a Ghost Portal, but instead of it turning me into a halfa, it did me in. I managed to stumble out and collapsed. The last thing I saw was Sam and Tucker running towards me, looking horrified." He winced.

Dora patted his back, a solemn expression on her face.

Timepiece weakly looked up at her and gave a fragile smile. "They picked me up and ran towards the hospital. But it was already too late. My soul had already dislodged itself from my body and flew through the portal into the Ghost Zone. I regained consciousness on a small floating piece of land, not too far from Aragon. As you know—" He gave a sincere, slightly humorous smile. "—I had been deathly afraid of ghosts my whole life."

Danny and Danni grinned at each other. Funny how two phasmophobic kids could become half-ghost ghost-fighting superheroes.

"I basically freaked," Timepiece admitted. "And then Dora came along."

Dora smiled. "I was out of Aragon for a flight to clear my head. I spotted Timepiece panicking. I immediately knew that he was a new ghost since new ghosts glow way brighter than regular ghosts. He freaked out more when he saw me. I assured him that he was going to be fine and that I wasn't going to hurt him. He hadn't realized he was dead yet so I brought him to Clockwork. Clockwork explained everything to him and did something I hadn't expected: offered Timepiece an apprenticeship. Time of course accepted it. He's a good friend to have around. Whenever Aragon's abuse gets too strong, Timepiece talks to him and orders him to stop. My brother never really does stop but he does tone it down for a while, since Time's a high-ranking ghost in our society."

"Seems like a nice ghost boy," Fishtail said, voice-cracking, no doubt the story touched his heart.

Dora nodded and inched closer to Time. "He is."

Danni dropped to the ground, boots making dull thuds as she landed. She brushed her white bangs away from her eyes and smiled. "Timepiece, we're after Danny's alternate future self as you might know."

Timepiece smirked, not saying if he knew or not. The smile reminded Danny of Clockwork's I-Know-Everything smirk.

"Anyway," Danni continued. "We were wondering if you could come and help us stop him. We could use your time-manipulating powers and very, very, very, very,very, ver—"

"We get it," Danny interrupted.

"—Limited amount of omniscience." She smiled and held out a gloved hand. "What do you say? Do you want to be a Dimension Chaser?"

Timepiece glanced down at her hand. He bit his lip and clutched his staff.

Slowly, he removed one hand from his staff and shook Danni's hand.

"The Danny Fentons of each dimension need to stick together," he said with a smile. "Even if it means leaving a place to go back to the place of my death."

"Dimension Chasers?" Danni asked.

"Dimension Chasers," Timepiece answered.

A little while later, Danny, Danni, Fishtail, Timepiece, and Dora hovered in front of the Fenton Portal.

Timepiece stared at the swirling vortex that had caused his death with uncertainty. Dora noticed it.

"Don't worry, Time," she comforted. "You'll be fine."

The ghost gulped. "I-I-I guess. But—" he looked at Danny, Danni, and Fishtail. "—Won't people recognize me?"

"We'll buy you a disguise," Fish promised.

"I've gotta get back to Aragon," Dora said. She leaned forward and kissed Timepiece on the cheek. "Bye, Time!"

The apprentice blinked, startled that she had just kissed him.

"Timepiece and Dora sittin' in a tree. K-I-S-S-I-N-G!" Danni sang.

Time swatted his staff at her but she dodged. "We're just friends," he said blushing.

"Suuuuuure, you are," Fishtail said, joining in.

"Clueless!" Danny sang.

Timepiece smiled and rolled his eyes. "Whatever. C'mon, before I chicken out." He jumped through the portal.

The halfas shrugged and followed him.

….

Danni, Danny, and Fishtail hadn't just bought Timepiece a disguise; they'd gotten disguises for themselves too.

Timepiece wore a black sweatshirt with white accents and he wore the hood up to disguise his face. He'd taken his gloves off and exchanged his boots for black and white sneakers. He wore black jeans instead of his normal pants.

Danny and Danni were in their ghost forms since Danny and/or Danni Phantom didn't exist here but they wore the t-shirts, jeans, and sneakers of their human forms. Like Timepiece, they'd taken their gloves off.

Fishtail was in a mid-morph form halfway between his human and merman forms. His hair was half-white and half-black and his eyes were neon green. He wore a black DP t-shirt and his blue shorts along with his flip-flops.

Timepiece twitched as yet another person walked by him.

Danni sighed and shook her head, white locks flying. "Time, absolutely no one is going to recognize you. Stop stressing."

Danny sighed. "I agree with Danni. We've gotta focus on Dan. Time, is your omniscience working?"

The apprentice closed one eye and squinted the other before opening his eye and shaking his head. "No, sorry."

"Do you at least know what he looks like?" Fishtail asked.

Timepiece grinned sheepishly. "I got a quick glance on Master's screens but I kind of forget."

"You'll recognize him," Danny stated. "He's got greenish-blue skin, blood red eyes, and flaming white hair."

Timepiece looked past him. "Kinda like him?"

The halfas turned around to see Dan hovering above a crowd of people. They hadn't noticed his presence yet. Until he blasted the street with an ectoblast.

"Ghost!" someone yelled as everyone ran into the nearby shops in panic.

Timepiece sighed and willed his staff to appear. "The people of Amity Park have had ghost attacks ever since the Fenton Portal became operational. My parents and the Guys in White have so far managed to attack and chase them for long enough until they get bored or go back into the portal. They've never captured a ghost yet." He hugged his staff. "And I certainly don't want to be the first."

Speak of the devil, a honk from behind the quartet signal that the Fentons had just arrived on the scene. Danny grabbed the others and pulled them out of the Fenton Ghost Assault Vehicle's path just in time.

"Great!" Timepiece said. "My parents have shown up! It's time to go."

The others didn't move.

"Guys? Did you hear me? My parents can take care of this."

Danni shook her head. "Mom and Dad aren't the most…" she trailed off searching for the right word. "… knowledgeable ghost hunters."

Danny nodded in agreement. "They've had a half-ghost living under their roof for a year and have never noticed that or caught me."

"And besides," Fishtail added. "Dan's a lot more dangerous than most ghosts. And since he can't find you for revenge, he'll go after the closest thing to you: your parents."

Timepiece bit his lip.

Meanwhile, Maddie and Jack aimed their ectoguns at Dan.

"Freeze, spook!" they yelled in unison.

Dan smiled evilly as he looked down at them. "Just the two I was hoping would show up." He made two duplicates and they flew at the Fentons, knocking their ectoguns out of their hands and tying them up with ectorope.

He used telekinesis to bring them to eyelevel with him.

"Let us go!" Maddie demanded.

Dan chuckled. "Why should I? If I can't find the person I'm looking for to enact revenge on, you're the next in line."

"What did we ever do to you?" Jack demanded.

Dan smirked. "It's not what you did. It's what you in an alternate dimension did." He let out an evil laugh.

And got kicked in the face with a white boot in the middle of it.

Dan yelled as he tumbled to the ground, releasing the Fentons. They fell too but landed softer than he did.

"Jack, are you okay?" Maddie gasped, struggling against her ectorope.

"Fine, Mads!" he yelled back. "Just tied up."

"I think we can help with that."

Both adults looked up to see a white-haired girl in a black superherolike costume and a boy with half-black and half-white hair in a t-shirt and shorts standing there.

"Oh, please!" Maddie growled. "What can a pair of ghosts do for us?"

Danni turned to Fishtail. "Yep, I can totally hear Dad in her words."

The boy pouted. "Just 'cause I glow doesn't mean I'm a ghost." His eyes went wide. "Incoming!"

Danni jumped in front of the Fentons and threw up an ice shield, blocking a fire blast. Meanwhile, Fish ran up to the Fentons and started untying them.

"Seems like the Dimension Chasers followed me through the portal," Dan snarled, landing in front of the half-ghost girl and half-merman boy. He froze. "Wait. We've got the female Phantom and the merboy. Where's my past self?"

"Right here, old man!"

Danny slammed his booted foot into Dan's back, causing the futuristic ghost to cry out and fall over. With a growl, he took to the air, Danny following a second later.

Fishtail finished untying Maddie. "C'mon. Let's untie Da—Jack!"

"Hurry up!" Danni yelled, keeping the shield up. She looked back at the fight. "I hope this plan works, Danny," she whispered.

Meanwhile, Danny flew in a circle around Dan before slamming an ectoplasm-infused punch into his face.

Dan growled and threw a few fireballs at the hybrid. Danny threw an ice shield up to block it.

"Fight fire with ice, Dan," the boy taunted.

He had failed to notice a duplicate sneak up on him. Or at least he pretended not to notice.

Dan-duplicate grabbed him from behind and sent a Ghost Stinger coursing through him. Danny howled in pain. A blinding white ring appeared around his waist and split, transforming him back into human form. Dan-duplicate smiled and tossed the boy down into the street. Danny clawed at the air as he fell.

Now it was Danni's turn to pretend. "NO! DANNY!" she yelled, forming ice crystals on her eyelids and melting them, giving her the appearance that she was crying.

Dan absorbed his duplicate and smiled in satisfaction. Make the Phantom-girl cry? Check. Push Danny out of the fight? Check. His grin widened as he saw Danny slam into the ground, masked in a cloud of dust.

What he didn't notice was Danny throwing up a ghost shield the millisecond before he hit the ground.

Fishtail and Maddie finished untying Jack.

"Er, thanks, Mads and…"

"Fishtail," Fish introduced. "My friends call me Fishtail. That's Danni and Danny."

The Fentons stiffened at the name "Danny". Fish couldn't blame them.

"Listen, I think it'll be safer if you two go home," the hybrid said, standing. "I've gotta help Danni and Danny."

The Fentons glanced at the battle for the first time. The white-haired teen was clouded in a cloud of dust and the flaming-haired ghost was descending to his level.

"And don't worry." A smirk slipped onto Fishtail's face. "We will meet again." He quickly saluted Maddie and Jack and ran to stand next to Danni.

The Fentons glanced at each other before running to the GAV and driving home. Something told them that Fishtail wasn't lying.

A hooded figure watched them go as he stood in the shadows. He bit his lip and turned back to the battle.

"Did you really think you could beat me, Danny?" Dan asked as the dust cleared. He grabbed the halfa by his shirt, bringing him to eyelevel. "I am you, Danny. I have your powers. Well, except for your ice powers, but still! Fire melts ice."

Danny's eyes drifted over to Danni's eyes. He flashed them green briefly. Short enough for Dan to miss, but long enough for Danni to get the hint. She nodded slightly, barely enough for him to tell. She opened a gloved hand to reveal an ice crystal and tilted it so that the sunlight hit it at the right angle.

"What are you looking at?" Dan asked confused. He tilted his head to look at Danni.

… Only to be blinded by the sunlight reflecting off the crystal.

He cried out in pain and tried to block the sunlight with his arms, dropping Danny in the process. The hybrid kicked the ghost's leg out from under him, effectively tripping him.

Danny quickly jumped to his feet, using a bit of flight to get him up faster. He sprinting into a nearby alley but before he got there, Danni melted the ice crystal and turned her and Fish invisible.

Dan looked up just in time to see Danny's sneaker disappear into the alley.

"Nice job cornering yourself, Danny," he said with a grin as he got up, not even thinking about where Danni and Fishtail were.

Danny spun around as Dan entered the alley. The elder of the two powered up two ectoblasts, one for each hand.

"You're cornered, Danny," he hissed. "There's nowhere to go."

Danny grinned. "I may be cornered for a normal human."

Dan's smirk faded.

"But it's practically impossible to corner a halfa," he finished.

Dan let out an animalistic howl and lunged at Danny, fangs barred.

Danny did a backflip and landed on the wall of a building. He straightened up and grinned at his alternate future self. "Catch me if you can, old man!" He spun around and charged up the side of the building.

Dan snarled but followed.

About halfway up the building, Danny glanced down. That was a good enough distance. In a swift move that made professional gymnasts look clumsy, he performed a backflip over Dan and tumbled back down to the pavement, landing in a crouching position with one hand lightly supporting him. He grinned up at Dan before turning invisible.

Dan growled as he faced the sky again, preparing to do his own backflip. And froze.

Hovering in front of him was a figure in a black shirt, pants, and cape with a hood along with white gloves and pants.

"And who do I have the pleasure of meeting here?" Dan asked sarcastically.

The figure's green eyes narrowed in the darkness of his hood. "You've been looking all over Amity Park for me," he said. "But you forgot to check the Ghost Zone."

Dan looked confused.

The figure reached up with both hands and pulled down his hood, revealing his face.

Dan's eyes widened. It was the Danny Fenton of Dimension 4.

This Danny's eyes narrowed even more as he ran a gloved hand through the white streak in his hair. "You can call me Timepiece." With those few words he fired an ectoblast at Dan.

The future ghost didn't even try to fight back in his shock. The blast hit him in the core and sent him spiraling into the street.

Timepiece dived after him, green eyes narrowed, legs fusing into a ghost tail. Dan shook his head and just managed to dodge the apprentice's punch. He jumped to his feet and fired up two ectoblasts.

Timepiece willed his staff to appear and pointed it at Dan. "Time out."

Dan froze and started glowing violet. He grabbed Dan but the front of his jumpsuit and threw him through a brick wall, resuming time as he did.

Dan lay defeated on the ground. Danny, Danni, and Fishtail became visible next to Timepiece. Danny powered up a Fenton Thermos.

Dan's red eyes widened. He slammed his hand on the ground, creating a portal which he fell into.

Danny sighed and lowered the thermos. "Let's go after him."

Timepiece's confidence was immediately gone. "Do we have to?"

Danni raised an eyebrow. She grabbed the ghost by his shirt and threw him in the portal. She jumped in a second later herself. Danny and Fishtail glanced at each other before shrugging and jumping in to.

The next chapter is going to have the last version of Danny. I'm going to keep what he is like a secret.
