This is rated M for intense violence, violence, gore, suggestive themes, and adult language. I don't think there will be sexual content or themes, no lemons, no limes-if anything I will...Allude to it.
I decided to write this...Just because. I've watched and read enough of One Punch Man, even though I'm...Ehhh about it, kind of like Dimension W. I figured I'd do a crossover story with DBZ and OPM, to broaden my writing and work on some skills. Thanks for taking the time to read this, if you do, and thanks for reviewing, following, and favoriting-if you do that!
Anyways, onto the story.
Goku could say he was at ease for the first time in a very long time. It was well over six years since he could honestly think the simple thought. Peace.
The battle with Cell, Tarnuu, and Syrus had taken a lot out of him-out of everyone for that matter, by the end nobody was even moving-even a centimeter, but everything worked out for the better. Now it was a few months since those long and brutal battles-since Cell was killed, since Syrus and Tarnuu spent their time in isolation on the earth, and a few monthis into the long reign of peace and he was just happy that it was continuing, instead of taking a turn for the worst like it always seemed to do.
Gohan continued on with his studies and there were a few parties and occasions where everyone got together. Vegeta would often hang back while everyone socialized at the parties, though he'd join in once it got into full swing. Bulma refused to let him just sulk off on the side, and so per her nagging-he quickly got into the 'formalities' of a party on earth There was sparring and training, everyone would meet up every few weeks in order to test each other and show the progress that they made.
Another peaceful day was reigning, and the Son family were all gathered in the kitchen as Chi Chi prepared another mountain of a meal. Celera had been helping diligently in the trying task of cooking enough food for everyone, but after the phone rang a dozen times Chi Chi decided to take over and let Celera take the call. Chances were it was Bulma-because she'd call back until someone answered, and Chi Chi didn't want to deal with the bluenette at the moment.
"Hey, Celera. What are you doing?"
The long haired Saiyaness nearly glowered at Goku in annoyance as she turned her focus from the phone onto him. "Talking to Bulma on the phone, you should get a clue. Honestly brother."
Goku blinked, confused.
"She means you should learn how to use one." Gohan filled in, looking up from his studies for a second.
"They're really not that difficult to use..." Shaello added. "You dial numbers and press talk."
Goku shrugged, grinning for a moment. "I can talk through telepathy or whatever, so who needs a phone?"
Chi Chi snorted softly. "You can do all of that, but you can't operate a phone if your life depended on it." She turned her eyes onto Celera. "What does she want?"
Celera felt like sighing, but nonetheless answered. "She wants Goku and I to stop over, check out some invention."
Chi Chi didn't look pleased. She almost had the majority of the meal cooked and was waiting for the water to boil, cooking this much food was a chore-but she didn't mind it since it always made Goku happy. He did love her food, and Celera wasn't exempt. Cooking for so many heads-especially three Saiyans was a trying task. "Is she being persistent?"
Celera twirled one bang around her finger. "Yeah..."
Chi Chi crossed her arms. "Fine, you two go on ahead and see what this invention is. I don't want that phone ringing while we eat, I just got it installed before this big mess happened with Gero.
"Well okay." Goku shrugged as Celera ended the call, setting the phone back down.
"Okay people! Fire it up!"
"But, Bulma-"
"I haven't gotten any sleep either, so we have to get this done!"
Bulma realized that she'd been up for days and nights working on the time machine. Then, she had been spent even more nights awake working on her Anti-Cell device prior to getting started on the time machine. It had been to the point where she was getting delirious and everything started to blend together in one giant mash of imagery.
Bulma gave her head a gentle shake, clearing the sleep from her mind and focusing on the time machine. "We're almost done, just have to do a few more tweaks. Then all of us can get some shut eye."
She powered up the machine, and the targeting mechanism-what she presumed locked onto a certain timeline, began to flash with green lights going all the way down the panel. It was a relief that it actually worked, because she had modified this at the last minute to accommodate several people-since the androids wanted to go back in time and all.
"I can handle the rest from here." Bulma declared.
A collective sigh of relief sounded from all of the workers.
"You've been working for twenty nine hours, I've been working for forty hours! Keep your sighs down please! I pay you for a reason."
Thankfully, she didn't even need to grab a phone to call Launch or Celera-the second could actually operate a phone unlike Goku.
"Hey Bulma, we're here!" Celera called out in greeting, waving her hand as she entered the room with Goku a few steps behind her.
"Wow! I can't believe it! You actually made a time machine!" Goku inspected the machine carefully, tapping his knuckles against one side of it.
"I know. You're at a loss for words" Bulma gave a cocky smile, but sighed softly.
"So..." Celera scratched her head, crossing her arms over her bosom. "How are Goku and I supposed to help?."
"About that...I'm trying to convert its energy source to what you guys call ki."
"Energy source?" Goku took a seat on the floor, scratching at his chin.
"Fuel, basically." Celera chimed.
"Yeah, pretty much." Bulma laughed softly, shaking her head. "Your guy's ki is almost limitless...I know there's a limit to it, but if I can convert this time machine's fuel source into ki-which you guys use, there won't be a need for whatever fuel source is in here...I'll be honest, I'm not even sure what it is-that's why I have to convert it."
"Well, you did make one twenty years in the future, maybe it's a different fuel source?" Goku ventured.
"But, considering it was twenty years in the future and the androids destroyed everything, there's not much that could be converted into a fuel source. I doubt fossil fuel would suffice for machinery like this." Celera said with a gentle wave of her hand.
"I guess I never considered that." Goku said with a blank expression.
"You're fine and intelligent, you're a babe Celera~!" Bulma said in a sing song voice, not at all ashamed to say it.
"Is that why you did what you did those few times and said my sister is going to make you go les-"
"We do spend a lot of time together." Celera looked thoughtful.
"Okay, both of you! Enough" Bulma quickly cut off the siblings before either could finish. No need for that to be up in the air when it was supposed to be a secret between herself and Celera. Honestly, Celera lacked tact just like Goku did, just in different areas.
"I'm just curious is all..." Goku looked at Bulma while tilting her head.
"Yes. But, you keep that to yourself...Celera you weren't supposed to tell him about that!" Bulma shook her head in pointed disappointment, something that made Celera scowl a little and turn away. "Anyways. I need you guys."
"But, I don't know how to convert a fuel source..." Goku said, completely at a loss.
"I'm converting it, you just have to power up or whatever it is that you do." Bulma looked at her old friend, a small frown on her face.
"Well, okay then. If you say so."
"I'll help as best as I can." Celera said softly, but her voice remained firm.
"This doesn't involve needles though, does it?" Goku asked, looking increasingly anxious.
Bulma turned to Goku, and he could feel annoyance bristling down her spine. "You're a big baby."
"I don't like needles..." Goku muttered before trailing off.
"Brother..." Celera straightened her back, leveling a sour gaze with him. "Why would she need a needle? She's now drawing our blood or anything like that-this has to do with our energy."
"Thank you, Celera..." Bulma rubbed at her forehead, voice shifting ever so slightly. Getting through to Goku was about as successful as talking to a wall and getting it to respond.
"Are you sure?" Goku asked carefully.
"You're going to be afraid of me when I break my foot off in your ass." Celera grated through clenched teeth.
"Your sister is right. I don't need to draw blood, and besides if I even had needle around me you wouldn't have come in here." Bulma's voice didn't waver the slightest.
"I'll help, but I'm sort of hungry."
It took a few minutes, but Bulma had an obnoxiously sized pizza made with everything but the kitchen sink put on it. Goku took a slice and shoved the whole thing into his mouth, giving a thumbs up as he grabbed another piece and jumped into the cockpit of the time machine.
"Goku! Don't you dare get sauce on those seats!"
Goku looked shocked for a moment, catching some toppings that would have hit the seats. "Oops."
Celera joined him on the seat to his right, giving him an exasperated look of annoyance. "Do you have to be such a slob?"
Goku shrugged, shoving the rest of the slice into his mouth.
"Bulma!"
"Right!" Bulma began to punch in a series of buttons on her computer, glancing at the time machine every few seconds as the lights blinked from red to green before remaining green and flickering. "The future me really outdid herself. There's so many different things in this time machine, I'm not entirely sure where to begin with it, so I thought converting the fuel source would be a good start."
Goku only shrugged.
Bulma took the silence of the siblings to continue on with her explanation. "There's 'outlets' in there as you can see by the control panel. If you put your hands there, doesn't matter which one, and power up-we can get this started."
"Sure." Celera set her hand on the panel. "No, Goku. You're not going to use that greasy hand."
"Why mot?" Goku asked before setting his clean hand next to her own.
Bulma sighed in annoyance, leaving the room in a flash. "Give me a second guys, I've got to do some reconfiguring."
Goku's hand slipped, pressing a series of buttons.
"Warning! Stability imbalance! Dimensional interference! Verse interference. Over ride! Over ride!"
The machine began to shake violently.
Celera dinged her head off the side.
"Dimensional?" Goku questioned with a blank look on his face. "That's what Vegeta always used to say-I'm going to send you to the next dimension."
"Look what you've done this time, you stupid oaf!" Celera barked.
"I didn't mean to..."
"If this whole place blows up it is your fault, you imbecile."
"We can just turn it off and tell Bulma what I did when she gets back." Goku suggested with a shrug, looking over Celera's arm and noticing a bid red button. "Ah! See, there's the shutdown button!"
"Don't press anything! Do you have any idea how bad you can damage the circuitry!?" Celera snarled. "Do you even know what dimension or verse means!?"
"How would I know anything about that?"
"It is common sense!"
Goku scowled, eyes roaming the panel for anything that looked like it wouldn't cause an explosion-disappointed that nothing fit his criteria. It was all beyond confusing.
"I'm getting something to drink then. I'll let Bulma know it's starting to shake." Goku said with a frown, a little peeved he was getting torn out by his sister. He banged his head off the metal of the entrance flap, howling in pain for a second as he crashed back into his seat-pizza and hands flying all over the place.
Sparks began to fly around the time machine before purple arcs of electricity began to surge around it.
"Warning! Warning! Entering universal manifold!" The automated voice exclaimed.
"Oops!" Goku said, looking sheepish.
One arc of electricity cracked off the window, nearly shattering it on contact.
"Talk about electricity...The hell did you do?" Celera tossed the pizza slice out before the hatch closed on them.
And, just like that they were gone.
Celera didn't immediately open her eyes. No need to irritate her eyes more with the disaster of Capsule Corp or wherever they were. She also didn't want to see her brother's stupid carefree face at the moment. Judging from the pressing on the back of her neck, she had been inadvertently knocked out-probably from being flung off to the side where her head crashed against the glass.
With a sigh she pressed her arm to her eyes, carefully opening them. Seeing only black, she inched her arm away little by little, until the sun's bright light was beaming right in her face and caused her to flinch away. She covered her eyes back up, groggily sitting herself up and feeling around beside her-the solid frame of her brother letting her know where he was still present.
It was also his snoring.
She took a moment to go through a sequence of buttons-the hatch above her shifting for a few moments before it slowly opened. Wind and heat immediately assaulted her senses and her hair as she took a look at her surroundings. It was a forest just like the one back at her home in the mountains-there were no mountains around her oddly enough. The ground was flat for the most part, covered in trees and shrubs.
With a quick flex of her leg muscles she sprung out of the time machine, soles compacting with the earth as she heaved in a breath. The air wasn't charred and didn't hold the scent of blood, so wherever they were was experiencing a peaceful time. Her eyes shifted as she whirled around-spotting buildings in the far distance, and could sense numerous people around her.
It's peaceful here at least, that's good...
"My aching head..." Goku groaned, pain evident in his tone as he landed beside her, nursing his skull. He looked around, not entirely familiar with his surroundings.
"Where are we?"
"I'm not too sure." Celera gave him a critical gaze before sweeping through the area, and miles beyond them. "I'm not sensing any Saiyan energy. There's humans, and..."
Celera furrowed her brows. "Not humans, too, I guess."
"Maybe we went back in time really far?" Goku suggested.
Celera looked around, eyes narrowing. "I don't think that's it...I think we're in a different time and place completely. The earth is the same, but everyone we knew isn't alive or doesn't exist. You send us to a entirely different universe or dimension, brother."
Goku took the explanation in with wide eyes, before jumping back into the cockpit. He noted everything was blinking red, which couldn't be a good sign. "Looks like the converter thing is broken too."
As if Goku cued it-the machine erupted in smoke and debris, forcing the both of them to speed away from the explosion.
Celera sighed. There were only bits and pieces of the time machine left, and there was no way she'd be putting it back together, nor Goku for that matter. "Looks like we're stuck here now..."
Goku landed beside her once more, cupping his hands behind his head. "We can look around. I think we should be able to find a fuel source here."
"The fuel source was something twenty years after our time, and the converter broke. The time machine is bits and pieces now. I also don't know how to fix any of that, not that there's anything left."
Goku nodded, a contemplating frown on his face. "I guess we really are stuck here...We should take a look around in that case, doesn't hurt to know where we are..."
"Only you could be so optimistic, brother..."
Goku shrugged, grinning for a second. "Gohan and Shaello are strong enough to handle any threats. There's Vegeta and Trunks too. They've all ascended."
Celera relaxed a bit, uncrossing her arms. "Lead the way, in that case."
"Right."
Before they could jump into the air and fly, or speed off on foot-several explosions erupted, making both of them trail off in their thought. There was quite a bit of energy powering them, nothing too alarming for them, but it was still a good chunk of energy nonetheless. If it made impact with the ground itself it'd be able to level the entire city it struck with ease-which alarmed both of them. It wasn't like Frieza, Broly, or Cell-who packed enough energy into their blasts to destroy the entire planet itself.
"We'd better move fast. Let's just run, don't want to cause panic and all." Goku said.
"Right."
