This is a crossover between Dragon Ball and Naruto. I hope you guys enjoy

HBTC(Hyper Bolic Time Chamber)

Goku, Vegeta, Trunks and Gohan were all training. It was Goku and Trunks VS Vegeta and Gohan. "Grrr...At least try to take this seriously you brat!" Vegeta snapped. "Sorry Vegeta, it's just it's kind of hard to go at my dad with a killing intent." Gohan replied. They all powered up. Suddenly, there was a flashing light that summoned all of them to Konohagakure.

Konoha

Tsunade was sitting at her desk doing paperwork when four of the universe's greatest warriors crashed through the ceiling unconscious. Anbu suddenly appeared all around the fifth Hokage, ready to kill. "Fetch me Inoichi" Tsunade told an Anbu with a bird mask. "Right away ma'am" he replied. Inoichi burst in a minute later. "You rang Miss Hokage?"

"Yes, I want you to scan these four people's memories." Inoichi immediately did what was told of him and started with Goku. He skipped right to his fight with Vegeta for the first time.

"You'll PAY FOR THIS!!!" Vegeta screamed out of rage as he flew up into the sky. He put his arms next to his head and a purple ball of ki appeared in his hands. "Galick..." Vegeta started to say. Goku went Kaioken. "Kaaa...meee...haaa...meee..." Goku said as he was about to try to blast Vegeta back to space. "Gun!!!" Vegeta said as he fired the attack.

"HAAA!!!!!!" Goku replied as he also fired a blast. The attacks clashed.

Inoichi quickly moved his hand after he felt a sharp burning feeling on his hand. He went to Vegeta next, where it showed Vegeta killing Android 19.

Android 19 was running as fast as his legs could carry, but it was no use. Vegeta already held his hand out as a blue and white ball appeared a few inches from his hand. Vegeta could only chuckle and grin as he sent the blue ball from his palm. Poor Android 19 already had both of his arms ripped off by Vegeta but this? This was just too much. The attack caught up with the Android in no time flat and you could hear the poor cyborg's scream from a mile away as he was vaporized.

Tsunade could see the frightened look on Inoichi face. Actually it was half excited half scared. "Lady Tsunade, I haven't scanned the two younger ones but these two older ones have immense power." "How strong?" she asked him. "I'd say strong enough to destroy the Five great nations by them selves." "WHAT?!?! NO WAY!?!?" she yelled. She couldn't believe it. "On the bright side, if they end up being allies, we could very well become unstoppable."

"We should wait for them to wake up but let's tie them up and have Anbu all around them just in case they're evil." Tsunade said. So that's exactly what they did. Vegeta was the first to wake up. "What the— where the hell am I?" he snapped as he looked around. He could see people surrounding him with weapons out. "Are you guys gonna attack me?" Vegeta asked grinning, as he was looking for a fight because he felt stiff. That's when Tsunade started talking. "If you're here to attack us then yes." Trunks woke up at this time. "I don't think it's a good idea to provoke them dad, we don't know how strong they are."

"Yes I do. After I woke up I felt their energy. I doubt even Yamcha would have trouble taking them on." This surprised Trunks. "WOAH EVEN YAMCHA?!?!" Tsunade was getting tired. "Just explain to me why you destroyed my roof and my office."

"We didn't mean to destroy your office but I have a theory on how we got here." Gohan answered. "I think it's because we l powered up and it was to much for the chamber to take."

Goku awoken at this time. "But we've done that many times before." Goku started. "But we were never that close to each other dad." After things cleared up they left. Tsunade said they were free to stay at the apartments. "Hey Gohan, are you feeling okay?" Goku asked. "Yea, why?" That's when everyone else realized. "Wow GOHAN YOU'RE ABOUT GOTEN'S HEIGHT WHEN HE WAS EIGHT!" Trunks exclaimed. "SO ARE YOU TRUNKS!" he replied.
