In which Izuku is not the nice, friendly kid we all know and has some SERIOUS training behind him. Also, if you can't guess what the crossover is then you fail as an anime fan.

(And in case you were wondering, this is set a year pre-Raditz so expect Izuku to have some time in the events of the other world. Have fun!)

A lithe, somewhat muscular figure walked down the streets of Mustafu unconcerned by the comings and goings of others. They had a hood up, and a bit of green hair poking out from under it. Their skin was a bit tanned, from spending a considerable amount of time in the sun. They had an odd visor on top of their head, and a pair of fancy looking headphones around his neck. He wore loose pants that had clearly seen some use, and well worn shoes that were built for speed.

The teen suddenly ducked into a little known alley, and disappeared from the street view.

"Oh hell... you're back?" said the bouncer.

"How's the crowd?" asked the teen calmly.

"For this early? Fair enough. Most of them will duck out of the fights once they find out you're back."

"I could care less. I'm just here to kill time and maybe get a decent fight," he replied.

The bouncer nodded him in.

"Have fun."

The teen opened the door, leading into a bar that was off-limits to the casual civilians. Only someone proven to have a certain lack of...regard...towards the rules were allowed in.

The teen had earned his place in the fights soon after his mother's death and his reputation had only risen since. None of the casual fighters dared to go up against him now, and only the really serious ones would play with him.

To a normal person, the teen looked little more than a delinquent. Especially since he was in the bar during what would normally be school hours.

As predicted, once they registered his presence, the casual fighters gave him some space. Not enough to act as though they were avoiding him, but enough to be considered 'respectful'.

"Long time no see," said Dabi.

"Yo, Stitches," said the teen unconcerned.

"I told you, my name is Dabi!" he said annoyed.

"Until you stop being a dick, I'll call you Stitches. We're not some weak-ass heroes to give two shits about hurting someone's feelings," snarked the other male.

"Fuck you," said Dabi, flipping him off. "So where did you disappear this time, Zero?"

"Went to visit some friends for extra training. That test is coming up soon after all," said Zero.

Dabi scoffed, but didn't say another word. He knew why Zero was planning to even take the UA entrance exam and it had nothing to do with being a pro hero.

Zero hated the pro hero class almost as much as Dabi himself did, but he had promised his mother he would at least attempt to graduate from UA.

"Any promising players?" asked Zero.

"Just the same old, same old," said Dabi unconcerned.

Zero ordered a few drinks, ate a bit...then left the underground fight club. He had mostly visited to remind people he was still very much alive. A few idiots challenged him, but were put in their place easily enough.

Honestly, after visiting that one group he found the fighters back home very lackluster.

Zero looked at the envelope containing his graduation certificate with trepidation. He was crashing with Dabi, mostly because despite their sniping they were actually good friends to an extent.

"Izuku? That's your real name?" laughed Dabi.

"Shut it, Stitches," said Zero.

The two wrestled a bit, with Zero the obvious victor as he was more used to fighting without a quirk.

"Asshole," said Dabi.

"Dickless," Zero shot back.

"At least I've slept with a woman, virgin!"

"I'm only fourteen, bitch!"

"Jerk!" Dabi shot back, carefully getting up.

"At least I know how to cook."

"Do you want me to set your bed on fire again? Because I can and will do that, you little shit."

Zero flipped him off.

The two had an unspoken agreement not to make any pot shots involving their mothers. It was a touchy subject for both of them and any idiot who dared to say a negative word about them either had their head caved in by Zero's fist or were turned to ashes by Dabi's flames.

When it came to the subject of fathers though...that was ironically how the two ended up bonding as close as brothers. Even though Zero had no experience with such a thing and Dabi had left his own siblings behind.

It was amazing what a shared loathing of the same person could do in regards to friendly bonding.

The resulting spat caused Zero's visor to be knocked off his neck...and for one of the buttons to be pressed.

Zero was about to really get into it, had he not noticed the way the visor was blinking.

"What the hell? I thought it was already used to your energy signature."

"Your toy is on the fritz?" snarked Dabi.

"I don't think so. I think you accidentally caused it to switch functions. I don't know even half the things Bulma put on it."

Zero cautiously picked up the visor and put it on properly. Then he stared.

"What is it?"

"...I think this is a Dragonball radar."

"What?" said Dabi.

"A Dragonball radar."

"Uh-huh...and what's a Dragonball?" asked Dabi. He didn't get what the big deal was.

Zero's grin was downright frightening. He knew what the Dragonballs could do...and the only reason he hadn't hunted them down on Goku's world was because he had been told (rather bluntly) that it would be nearly impossible to grant his wish because his mother had died on his world and they wouldn't work on others.

But if there were Dragonballs on his world...then that was another story entirely.

"I'll tell you what it is...it's a way to kill our boredom," said Zero. He had a rather frightening grin on his face.

Dabi raised an eyebrow.

"What's in it for me?"

"You help me collect the set and I'll introduce you to the place where I learned how to get strong enough to kick your ass with ease," said Zero.

"Deal," said Dabi.

The second Dabi saw Zero flying, despite the fact he knew damn well that wasn't his quirk, he wanted in on whatever training Zero had done. Being able to fly and launch fireballs at Endeavor was too tempting to pass up.

Besides, he hated driving.

Six months later...

Zero tossed the ball up and caught it one-handed. This was it. The last Dragonball to collect the entire set.

Dabi still didn't get what the big deal was, but he had already convinced the people who had trained Zero to become so strong to teach him as well. Goku wasn't exactly the sharpest tool in the shed, but he was a damn good fighter.

Then Zero used the special summoning incantation. Dabi had only one thing he could say at that moment, when it woke up the sleeping power within the weird trinkets Zero insisted on collecting.

"...You just summoned a massive fucking dragon. What the hell."

"...Pretty sure his name is Shenlong, if he's anything like his other counterpart," said Zero helpfully.

"You. Summoned. A. Fucking. Dragon. EXPLAIN."

"What is your desire?" rumbled Shenlong, making Dabi twitch. The thing could talk too?

"The resurrection of Midoriya Inko to this location," said Zero without hesitation.

The dragon looked at him, and the sky rumbled with lightning. Dabi looked at Zero like he was crazy.

"You're kidding right? Nothing can raise the dead."

"If that is your wish," rumbled the great beast. The sky light up with divine power, and Dabi had to shield his eyes for a moment. So you could imagine his shock and disbelief when something appeared nearby...in the form of a woman about twenty or so looking very confused. However it was her features that had his full attention. He recognized them pretty fast considering the teen next to him looked far too much like her.

The dragon glowed brighter, before the trinkets Zero insisted on collection flew up into the sky, before scattering.

Dabi immediately grabbed Zero by the collar and glared at him.

"Zero...what the actual fuck did you just do?" he demanded.

"Izuku-kun?" said the woman, confused and bewildered.

"Hi, Kaa-san," said Zero tiredly. "Look, I'll explain it later but first let's get the hell out of here before the heroes show up to investigate. Besides, they can explain it better than I can."

"There had better be some damn good booze after all this."

Zero grabbed Dabi's shoulder and his mother's hand, before disappearing using his quirk. A good thing too, because the heroes had been hot on their trail anyway for how they acquired the Dragonballs.

On another Earth...

"Wait...you're telling me those things we collected can grant actual wishes? Like real ones?!" said Dabi incredulous.

"Anything from resurrecting the dead to immortality, though the second one hasn't been confirmed," said Bulma.

Zero was too busy catching up with his mother, who took it in stride and had a few secrets of her own to tell to listen in to the subject.

Dabi glared at him.

"Why the hell couldn't you tell me this before?"

"One, you wouldn't have believed me, and two, I wanted to use the wish to bring mom back. You would have just used it to rob Endeavor of his quirk or something equally ridiculous, and I didn't want to wait another year," deadpanned Zero.

Dabi could at least concede that point.

"So we have to wait a year before we can use them again?"

"It's because they need to recharge after they're used. Makes it harder for people to make consecutive wishes anyway," said Bulma.

"And why didn't you tell me you added a Radar to my visor?" said Zero.

"Because I honestly forgot about it," said Bulma. "I was playing around so much to see what I could add to it that it slipped my mind."

"So what happens now?" asked Dabi.

"Mom is staying here. It's going to be awkward enough to explain why she's alive again and I have no intention of alerting any of the factions about the Dragonballs. Plus you'll need to stay here until the heat cools off, so you'll have plenty of time to train up to my level. You did say you wanted to fly," said Zero.

Dabi wanted to grumble, but he wanted to get stronger and he had very little waiting for him back home anyway. Besides, he had taken one look at the capsules Bulma's father was working on and wanted some of his own. They looked too useful not to want a set.

"Mom, you can use my accounts here to settle in. Dabi, I'll give you limited access on the condition you act as her bodyguard until you get your own funds."

"Deal," said Dabi. "What are you going to do?"

"The UA exam is coming up soon, isn't it?" said Zero smirking. "I plan to apply and have a bit of fun. And if I happen to see that man there I'll be sure to record me kicking him in the balls. After all, it wouldn't do to completely rob you of the fun of beating the shit out of him."

Dabi smirked at that. Zero was a little shit, but he was one he could easily tolerate.

"Next up, Midoriya Izuku," said Cementoss.

"Why is there no quirk listed?" asked Aizawa.

Present Mic looked at the file and winced.

"According to this there was an...accident... when the kid was only two and the tail he had was more or less cut off. His mother had the remainder removed," said Present Mic.

The rest of the teachers cringed. That had to be rough, being born with a tail only for it to be removed so young. At least it had happened early enough that the kid had likely learned to adjust.

Still, that kid had racked up more points than any other applicant...and that was before the Rescue Points amplifier was added.

"His martial arts skills are higher than the others. With the right support tech, he could be a great hero," said Midnight.

"So we're agreed?" said Present Mic.

"Midoriya will be in class 1-A. I can't think of anyone better suited to train a hero who doesn't rely on their quirk than Aizawa-kun," said Nezu.

The teachers went to the next student.
