I really need a new name for Time Patroller Trunks rather than Xtrunks…

SO MANY MISTAKES TO BE CAREFUL OF.

P.S. The Buus that are drawn over come from times where things more or less left them the strongest or at the end of their lives so certain parts of their histories are different.

Buutenks had killed Gohan before Goku could arrive with the Potara.

Buucolo managed to stall Gohan long enough to intercept Goku and kill him.

Gotenks and Piccolo were unable to escape the Hyperbolic Time Chamber to stop Super Buu.

Kid Buu was just about to be destroyed by Goku's Spirit Bomb.

Good and Bad Buu had split and would have destroyed each other after Hercule had run away.

P.P.S. Reviews are appreciated.

Majin Buu was of two minds when it came to fighting Kid Buu.

On one — not very important — hand, they had been working together till now.

Which consisted of about an hour.

On the other — much more reasonable — hand, the little Buu was a jerk and kept knocking Majin Buu around without care and hurt him for no reason.

Which consisted of most of that hour.

He could tell the person he and the little Buu were fighting was super strong and was able to fight with both of them at once. Instead of attacking Buu though, he tried to talk to him without being mean, and it meant a lot to Buu. He liked to fight for fun and the man promised he would play with him so long as he won. If Buu got to have a friend to play with by beating the little Buu, then it was an easy choice as he didn't like the little Buu anyway. He wanted new friends, a bunch of friends who would be happy to play with him and make sure he didn't do bad things.

So he fought.

Not that it was going well.

Buu wasn't stupid to think he was weak; he was strong, but this little Buu was much stronger than he thought and he was having no fun in this fight. The little Buu was constantly laughing and making fun of him and he couldn't shut him up, which made Buu unhappy. Buu had tried to turn him into candy and the little Buu danced out of the way only to dash at Buu with a cackle. He kicked Majin Buu and sent him flying and then few after him intent of pummeling him, but Buu managed to flip to land on his feet and launch himself at Kid Buu. Buu and him crashed into each other in a blur of arms and legs, Majin Buu finally able to land some blows but taking far more as shockwaves echoed from their blows. Majin Buu let out a cry as Kid Buu twisted over a punch to kick Majin Buu back down and then follow it up with a ki blast that sent Majin Buu into the ground. Majin Buu grumbled from where he was buried and steam drifted from the cracks as he was getting angry at the little Buu. Kid Buu landed on the ground to crouch and cock his head at the steam, not realizing the position he was in.

Majin Buu's fist erupted right in Kid Buu's face and sent him flying up with a surprised cry, only to suddenly be pelted by ki blasts courtesy of Majin Buu who was now grinning in triumph.

Only for a few seconds before Kid Buu focused.

Kid Buu blitzed down and shoved his foot into the ground, scowling at the fatter majin.

Buu looked confused at what seemed to be a random act until Kid Buu's foot shot out of the ground and uppercutted Majin Buu straight in the chin.

Majin Buu fell back with a cry of pain only for Kid Buu to immediately begin to hammer him with a barrage of blows.

Majin Buu was doubting he could win this fight.

Xtrunks let a smile quirk his lips as nothing remained of Buucolo after a burning attack hit him dead on. He had been very careful to completely and utterly destroy the majin with nothing left for him to come back from. Xtrunks closed his eyes and sensed where everyone was and how they were faring in regards to their fights. Goku was still battling his Buu but Xtrunks could tell each of them were losing steam — even though Goku was already maintaining a better grasp of his form and stamina — fast enough for things to be too close to be safe. His father was still going strong even with his opponent losing power as Vegeta was facing a weaker version of Buu. Gohan was still in a deadlock with Super Buu but neither had and edge over each other as they fought in the nearby had apparently already tapped into Kaio-ken and was already on the verge of victory based on his buu's wavering ki.

Xtrunks blinked at ki of Majin Buu and Kid Buu clashing against each other, he hadn't expected that to happen.

Had Kurai managed to change Buu or was it something else?

Xtrunks shook his head.

He could worry about that later, the more the fought the better the chances for the rest of the Z-fighters.

Xtrunks decision was made and flew as fast as he could to aid Gohan and help him beat his Buu.

Buutenks let out a mouthful of spittle as Vegeta's fist buried itself into his stomach with enough force to level a planet. Buutenks had been certain that he could've taken on Vegeta easily, but this was not the Vegeta he was expecting. For one thing, this Vegeta was alive when the one he knew of was still dead and in hell for the foreseeable future. Also this one could could actually transform into a Super Saiyan 3 whereas he didn't think Vegeta was even aware of it until Goku had used it on his previous incarnation. Even then, Buutenks had been beating Gohan and the Vegeta he knew was nowhere the demi-saiyan's power level at that time.

But unfortunately for him, this Vegeta was stronger than the one he had known.

Considerably stronger.

Enough that he was outclassing Buutenks in every way.

Buutenks had tried to absorb the prince but Vegeta immediately dodged the glob of his mass and blasted it into oblivion.

"You dare try such a pitiful tactic on me?" Vegeta snarled as he dashed in and punted Buutenks in the face, "So weak that you need to absorb a foe rather than beat him on your own? You make me sick!"

He had tried to make more ghosts to hold Vegeta off but the prince had not let him fire off any of the techniques that would give him a moment to recover. He had been unrelenting in his assault and forcing Buutenks on the defensive the whole fight after the first few minutes of this fight on the Kai's world. Buutenks had hoped that this would only be a minor obstacle but Vegeta was far more than that. Buutenks had tried to find a gap in his assault to strike back but any opening had only turned out to be feints to give a punishing counter. Buutenks had begun to flag heavily as the battle carried on and he was now in the very real danger of dying if he didn't get a reprieve.

He grit his teeth and let out a scream as he began to glow.

"How about I try what you did?!" Buutenks screamed as he flew back.

Vegeta realized what he was about to do — he knew what that version of him had done to try to beat buu— and shot after him into the air before he could focus his energy. The prince snap-vanished into Buutenks' path and attacked him with a barrage of punches and kicks before knocking the dazed majin into the sky. Vegeta began to juggle the majin through the air as he snap-vanished every time he redirected the majin's path via punch until the majin was too beaten to even try to block. But Vegeta kept doing it until Buutenks weakening ki was almost gone entirely, he wanted to make sure the majin knew what awaited him if he came back from the dead.

"Final Flash!" Vegeta roared as he fired one of his signature attacks at the dazed majin.

Buutenks screamed in disbelief before the attack enveloped him and reduced him to nothing.

Vegeta let out a breath and crossed his arms, noting the nearby ki's of his allies as he already sense his son approaching his mentor. Nodding to himself, Vegeta headed towards Goku and his opponent, intent on making sure Kakarot didn't draw this out.

Gohan grit his teeth as he was locked in a flurry of attacks courtesy of Super Buu, who while attacking was scowling in annoyance.

This couldn't go on forever, at least not for Gohan.

Gohan and Super Buu were just about the same power level, but the majin's unique body made leaving lasting damage difficult. That wasn't to say Gohan hadn't been making no headway against him, but no matter how many times he vaporized part of the majin, it just grew right back. While it did cost Super Buu a bit of power to regrow while Gohan tried to capitalize on the handicap, Gohan was just not able to deal enough damage in one go to overtake the Majin. Maybe he would gain a temporary edge if he went the next level, but Gohan knew it would only end up killing him. His small trips into The Hyperbolic Time Chamber had helped him achieve the same level of Super Saiyan as his father and Vegeta, but he had little to no time to refine the transformation.

Gohan backed away as Super Buu swung his arm, it stretching out like a whip as he tried to smash Gohan in the face.

Neither of them expected to see an ki blast his the Majin and make him cry out in shock and pain.

Gohan turned to see Xtrunks skid to a stop beside him, eyes focused on the now wary majin as his ki flared blue and yellow.

"XTrunks…" Gohan looked astonished, "What sort of transformation is that?"

"We can talk about it later." Xtrunks replied, "Lets finish this."

Gohan smiled and got into his stance, "Alright lets."

Goku and Buuhan punched each other in the face at the same time, sending them both flying back into ground.

Goku staggered to his feet as Buuhan did the same.

His power was beginning to fluctuate dangerously as the battle was dragging out too long and his opponent was strong. He had worked to try to refine his power consumption farther in Super Saiyan 3 since the talk on Kami's lookout but it was not easy and he had only got a bit better. Clearly he needed a lot more work than he thought, being dead had made the strain of Super Saiyan 3 so much easier to handle. Maybe he should ask Kurai if there were anyways to completely negate the strain on his body when this was over with?

Thoughts for later, focus on beating this Buu first.

Buuhan was frowning at the saiyan, wondering how this Goku was so different when he had been dominating the fight with the one he had fought after absorbing Gohan. Granted he was aware this was a very different timeline as he noticed Gohan was considerably strong than he would've expected considering he was only in his Super Saiyan 2 form and Vegeta had also achieved Super Saiyan 3 to great benefit, but he was assured that absorbing Ultimate Gohan had cemented his place at the strongest. The unlocked potential that he had been able to access from what was — at the time — the strongest fighter in the universe had been amazing. He was sure that any foe he came across would be nothing but a minor inconvenience for him to throttle.

Now he wasn't as sure anymore.

He didn't know what sort of training Goku and his allies did, but it had made them much much stronger than he had ever thought they could grow.

Perhaps saiyans and their hybrid offspring really didn't have a limit to their power; that they could ascend so long as they were alive.

But that simply meant he would have to destroy them before they would be able to grow too strong.

It was then a new ki arrived and Buuhan turned to scowl at Vegeta who had jus arrived, granted the prince was sporting a decent amount of damage but that didn't mean much.

"Kakarot!" Vegeta called, "Stop playing with your opponent and finish this!"

Goku frowned, "He's not that easy to beat!"

Buuhan straightened, laughing, "Of course not, I absorbed so many of you that I am undoubtedly the strongest! It was so easy to absorb both of your sons and kill off the rest of you all like gnats!"

That may have been the wrong thing to say as both saiyans stilled.

"What?" Vegeta said, voice deathly calm, "What did you just say?"

Buuhan smirked, not realizing the hole he was digging or — more likely — not caring, "Oh, you didn't know? I killed all of your friends and family, all of humanity, every single person on Earth. I left it a lifeless rock before venturing out to destroy the universe. You both tried to beat me but killing you both was child's play after taking Gohan's power for my own, you both died apologizing to your family for not being strong enough to save them."

Goku glared, "I won't let that happen!"

Buuhan smirked, "You may not have a choice, this little time displacement came with a small benefit I may have forgotten to mention."

A time-breaker symbol flashed into existence on his forehead and he was shrouded in purple ki as his power skyrocketed.

Goku and Vegeta both paled even as they readied themselves, they may not be able to form a cohesive team, but they knew when they were outclassed.

'Enemies that could flatten Super Saiyan 3 with a finger-flick.' Goku thought sourly, 'That means much more training than I thought.'

Piccolo was glaring at his foe, who had been unable to keep up since he began stacking his kaio-ken to higher and higher levels. Kaio-ken was something he had learned during his time in other world and while he had only shown a times twenty multiplier when he sparred with his allies, making sure that he was fully able to control his power. With his namekian heritage, merging with Kami and Nail, and its regenerative abilities he was allowed for much easier mastery and stability so he could crank it higher without overdoing it and that was without considering that he had trained hellishly with a clone in The Hyperbolic Time Chamber to make sure he could handle the strain of it. By the time this whole situation began he had gotten far farther than Goku had every tried with that technique and the benefits had paid in dividends.

The grey-skinned Majin lunged at him and Piccolo ducked under the charge to slam a kaio-ken powered fist into his stomach and sent him skyward. The Majin flailed as he tried to right himself as Piccolo charged a light grenade and aimed at the menace. He would have liked to use a Special Beam Cannon, but that had done very little when his opponent treated gaping holes in his torso as little more than a paper cut. Best erase him so there was no chance that he could ever reform and keep going he was going to end this now.

The blast flew upward and hit Evil Buu dead on, expanding into explosion that utterly erased the evil half majin into nothingness.

It was then Piccolo felt one of the Buu's power skyrocket.

He was moving before he was thinking, his kaio-ken leaving a shimmering trail of red ki behind him.

Gohan and Xtrunks moved in sync as they kept Super Buu on the back foot with minimal effort as their attacks brutalized the Majin. Whereas Super Buu was fighting Gohan on even terms before, Xtrunks inclusion in the battle tipped the scales far further out of Super Buu favor than even he thought. And whatever power Xtrunks was using was just too much for him to beat, and what was worse was that they both were very wary of his absorption ability and wouldn't give him a chance to use it. He knew the fight was over now and he had no moves left, except for the one move that he knew would let all the majins win by default.

He managed to let out a scream of rage and the shockwave forced and the two saiyans back enough for Super Buu to fly into the air and begin forming a massive sphere of ki. He smirked cruelly as he began to pump as much power as he could into the sphere of Ki that bathed the area in a pink glow. Gohan and Xtrunks both grimaced at the fact that Buu was doing what all the enemies did when things weren't turning out in their favor.

Super Buu was going to blow up the planet.

Gohan and Xtrunks traded a look, both of them raising their hand above their head and charging their power.

"Masenko!" They shouted in unison as Super Buu threw the sphere towards the ground.

The dual Maskeno twisted around each other until it became a single beam of energy that clashed against the planet busting attack that Buu had threw down. Gohan grit his teeth and let out a growl of strain as Xtrunks grimaced, this had a lot of power behind it and would definitely kill everyone if it hit the planet. Sometimes Xtrunks wondered if he should just wish that the saiyans could breath in space as it would make so many of the last resort attacks of the various enemies pretty useless if they could still keep fighting in the vacuum of outer space killing them.

Thoughts for later.

They both roared as they pumped more power into their respective attacks, and with Xtrunks' rage form boosting him, Buu stood no chance.
