Darc appeared in the timeline he was supposed to be and looked around.

"Alright, looks pretty much like the planet Tuffle. Has a lot of similarities to earth...Come to think, I should make a note to destroy that abomination called Baby. Don't want to think about it taking control over Broly or the likes. That would end up in disaster", he mumbled a little bit and started to sense his surroundings.

"Hmm...Goku is there..." Darc frowned after he stayed focused on his signature "Wow, that immense pressure I feel from him unbelievable...Better keep looking...wait, Gohan is also there. His Ki signature is somewhat different but still discernable. That means the others close by to him are Trunks, Goten and Pan. Trunks really has a completely different feel to him....Good, so the final battle is taking place. Got to hurry and help them."

Darc let his aura erupt full force and a very strong white corona surrounded him. Of course, he maintained control so that the planet would not suffer. Then he charged into the direction of the battle.

----

Just a few kilometers Goku had used the Kamehameha wave to put Oozaru Baby to the ground.

"Grrrr. HOW CAN I LOSE. I WILL NOT LOSE!" The evil thoughts started collecting around his body and a dark aura started to envelop him. "THIS....HAHAHAHAHA. That I could actually us the energy like that. Good!" Shortly after that he stood back up and flared out his own aura. The dark energy crept inside his body and he started to glow and shrink. He became smaller and smaller until it came to an end.

"Oh, no. This can't be good...", gritted Goku while watching Baby transform into the same form he was in. Pan and the others were also shocked by this outcome.

What they now saw was a white furred SSJ4 Vegeta. What made it even eerier was that his eyes had a red color and not the typical green color. He looked like an albino Saiyan if there ever was one.

And that would be all good and well if there wasnt the simple fact that Baby was still in control of Vegeta´s Body.

And that only meant real trouble now. Baby was already very strong but now it would probably be over.

His cold eyes looked at Goku and his confident smirk was a dead giveaway that he knew he was more powerful than him now. He placed a finger on his temple and grinned.

"Look at what happened. With your little help, I found out how to access this form. Just now when you absorbed my revenge ball, I finally realized that I could have used that energy all the time for myself."

Then Baby slowly lowered his hand and crossed them in front of his chest. Electric sparks started to surround his body. "Now I will make you pay for the humiliation!" With a powerful shout, he let his aura burst out. It was an eerie dark greenish aura.

"Pan! And the rest! Run from here! Now!", shouted Goku to the others and prepared to fight Baby with igniting his own energy.

They heard his shout and Pan frowned. "But what is going to happen to you?", asked Pan out of concern for his grandfather.

"We need to go, Pan. We can't do anything here...", said Gohan and wanted his daughter to follow his father's orders. But just at that moment, he felt a powerful aura. "Huh!? Who is that!?"

There was no need to say it since the others also notice the energy signature that approached at a fast pace. At least all but Mr. Satan.

It didn't even take long and Darc showed himself. He stopped and looked at the battlefield. It looked like he was a little bit too late to stop Baby´s transformation. Well, whatever. Nothing that can be done there.

Darc glanced over to Pan and the others and smiled to see them still safe.

"Well, look at that. I don't remember any humans having that amount of energy. Heh, are you here to help out? An ant like you should crawl back to where he came from.", mocked Baby him after feeling his power.

"Priceless coming from someone who was born inside a glass tube. Baby, that energy you just now absorbed was not meant to be yours. I am here to fix that little unexpected outcome....And don't you dare underestimate me!"

Darc charged his inner god ki and let it lose. His body was engulfed in a dark flame and his eyes brightness dimmed to a dark blue color. His expression became serious. Baby and Goku both noticed that his ki just vanished but an unbelievable increase in pressure came clashing at them.

"What is this? I can not feel your energy anymore, but there is a sudden strong pressure.", exclaimed Baby. Tha also made him change his focus to Darc now. "I don't like you coming out of nowhere and threatening me, human! Especially with that unknown form. Looks like I will need to take care of you first."

"We will see about that. Kaioken!!" Darc his Black and calm aura immediately became frantic and started growing like a hungry flame being fed with gasoline. It started devouring the surrounding air.

Goku was surprised to see his old technique being used right in front of him at this moment.

´Crap, this is still a little bit too much for me, I guess. Well, I still got to keep this up. I don't have another choice. With my godly form, I should keep up stamina wise.´, thought Darc after feeling a massive strain on his body while initiating this form. He also wondered how this strain would affect him later in the fight. His body should still keep recovering.

*Goku, lets team up. No slacking.* He sends that information to Goku and urges him to not fight alone. There was no room for that.

Goku received the telepathic message and was a little bit surprised but immediately charged up his aura, even more, to tell that he was ready.

"I don't know who you are but if you are a human and here to help us then I accept your help.", said Goku.

+++Battle Start+++

Darc charged forward against Baby and made a somewhat direct approach but before be hit him he vanished and appeared behind Baby to knee his head.

Baby was very surprised that after he vanished that it was hard to follow his movements and only in the last second he could defend himself with turning around and blocking with crossed arms in front of himself.

Then Baby smirked. "That tickles. Looks like I am too powerful for you."

Darc didn't bother and disappeared again just to appear some distance away and use blast against him. This time Baby did feel a little bit of pain.

"What the...Alright, you little pesky..." Just when Baby tried to engage Darc Goku came from the side and started a series of attack which Baby avoided.

Glancing over to Darc he could see him preparing another stronger blast. So Baby emitted a ki wave to push Goku away from him and send a blast to his body. Then he turned to a shot a few blasts in the direction of Darc as well.

Darc noticed that and avoided them but what he didn't expect was that Baby appeared right beside him and punching him. That punch was so powerful that Darc had to grit his teeth and lost concentration for his blast. Not only that but he was sent flying into some mountain range.

Goku tried to blast Baby with energy but it was either deflected or avoided. It was only a waste of energy. So he charged at Baby and tried to kick.

His kick was received with a kick of Baby himself and at that moment Goku felt the difference in their strengths. Goku was pushed back and got a punch in his abdomen shortly after that exchange.

"Gaaah!" Goku cried out in pain and tried to endure but he received a followed up that was a somersault kick. It sent him to the ground sliding on it for a dozen meters. Destroying everything he came in contact with.

But lucky enough Darc was already back up and engaged Baby before he could assault Goku even more. Darc executes three punches but all of them were intercepted by Baby one by one. With each punch, the surrounding ground shook and splintered into an even deeper impact zone.

Baby even started to frown a little seeing that Darc could keep it up with this amount of power. So he increased his efforts and grabbed an arm of Darc and made the hulk move with him. Slamming him from one side to another. Making sure that he kissed the ground repeatedly.

A few blasts from Goku interrupted him shortly and Darc could use a strong energy wave to free himself.

Retreating back to the side of Goku he wiped away some blood traces at the corner of his mouth.

"We are getting nowhere. I think he gained too much power.", said Goku and had to admit that this was a lost cause in terms of raw power.

"Looks like it. And I can't really go any further than the normal Kaioken without completely destroying my body.", approved Darc. "But we still have a way to beat him..." Darc looked to Goku "You still know the Metamoran fusion dance, right?", smirked Darc now.

Goku was once again surprised and looked at the stranger. "I know it. But I don't think we are on the same level of power. Your raw resilience is something but you are still getting overpowered by him and me in the long run. We need to be on the same level and if transform back we would lose too much power for the fusion."

"Don't worry about that. If it is just for a short time, I can push my power to your level. If we do the Fusion then, it should work. But please don't screw it up. We only have one chance. Ready?"

Goku hesitated a little because he was Goku and obviously liked to fight strong people but he also saw how Baby was now slowly approaching them. "Fine." Goku jumped to the side and prepared. "On your mark."

Darc nodded and now had to push his power to the level that Goku was at. He already felt it is about 10 times his energy. To make sure he should make it 15 times.

"Kaioken times 15!! Now!!" Just when his energy flared up immensely and a strong pressure crashed down on Goku and Baby he started to execute the dance. Goku knew about his power up and didn't get too fazed by the pressure and started the dance as well.

"What!? NO, YOU DONT!" Baby saw what they did and shot a flurry of blasts. He knew what they wanted to execute and he needed to stop that.

"Fu-sion, HA!!" Both cried out loud in unison and lucky for them they executed it perfectly at the first try. That being said Darc only followed the steps from the show. Good thing it was not such a complicated dance.

The blasts from Baby threw a lot of dust upon impact. And only when it settled could he see if he interrupted them.

A little bit to the side the others with Pan were shocked even more. "Did you see that, Trunks? Did dad just now fuse with some stranger", asked Goten.

"Yeah, I think so...But what will come out? Is he going to be strong enough?", answered Trunks and was also worried.

"Let's just hope so.", joined Gohan in.

"What is fusion?", asked Pan now.

"It is a very powerful technique that makes two people into one and creates a powerful warrior. That is if it is executed correctly...Let's just watch, Pan.", explained her father to her.

Just at that moment, someone started coughing. Not in a realistic manner but more as if acting.

"Hey, hey, can you not stir up so much dust. You know, it's bad for the lungs."

A figure with typical Metamoran clothes appeared and wiped away some dust from his shoulders. He had a well-defined body and looked pretty tall. His hair was jet black and it raged upwards like it was electrified. Three bangs on the left side of his face were the only hair that defied the others general way to the heavens.

The figures blue eyes were emitting confidence and the big grin the figure had underlined that fact. They stared straight at Baby.

"...So you two succeeded...But it looks like you didn't keep the Super Saiyan 4 form. Don't think you can beat me with just that. I am still far stronger than you.", said Baby and his anger now was skyrocketing. He will destroy them even if it is the last thing he will do.

The Metamoran´s grin subsided into a smile but his carefree expression still remained even after Baby said his words. The black monkey tail behind his back wiggled back and forth from left to right.

It was true that he was in his base form, but this base was built with two people as its foundation that reached the Super Saiyan 4 power level. Transforming into a Super Saiyan 4 would be pretty easy for him. But why use that if you got something else?

"Hmmm. I wouldn't be so sure about that if I were you. Let's see now. Darc and Goku...Alright, Dark it is. My name is Dark and...I don't think you will stand even a chance against me...Because I am a Saiyan God."

His words reverberated through the air and a powerful gust of wind traveled in every direction. Pressure started to build that was way more powerful than before. And the one that it was aimed at was Baby.

Dark´s hair color and eyes changed to that of fiery red. Accompanied by a red and orange intermixed aura surrounding him. Even his tail became the same red color as his hair. He entered his God form.

"Now then. Do you exit Vegeta´s body on your own or should I help you out?", said Dark with an intimidating smile. It looked like Darc his personality mixed very well with GT Goku.
