Vegetto fought with all his might. The creature was stronger than he expected. He knew that there was one last way to beat it, but he didn't want to go beyond his current state. After he punched it down in the ground, he launched a Kamehameha big enough to destroy the whole place. After the smoke cleared, he saw nothing more. Nothing was left of it. He didn't sense anything anymore. Satisfied, he turned around and flew to Pallet, not noticing the arm that came out of the rubble.
Ash could feel the presence coming. He took off, and flew in the direction of it. Then he sensed Vegetto coming his way. "Good, Vegetto must have finished it off.", he thought. He waited in mid-air, and then he saw the creature appear. It hovered a few meters in front of him. At that moment, Vegetto arrived as well. "Ash, be careful! This thing may look easy to beat, but he is rather strong!", he said. "Gotcha! Tell everyone to come out. Hey you! Let's go to that island over there!", he yelled at the creature. Vegetto saw that it looked the same as the one he was fighting. "Good Ash, I'll back you up soon!", Vegetto said, as he flew down. Ash took off to his training ground, and readied himself for the battle. He looked at the creature. It looked like a human, but his power is far greater than that of a ordinary man. They started fighting. After awhile, Ash had gotten hit a few times, they stopped. Ash turned Super Saiyan, and they continued. It was clearly that Ash had the upperhand now. He showed his enemy every corner of the island. Ash knew for sure he would win. He hitted it hard, and kicked it down. He then charged up a energy blast, and threw that at him. A loud explosion and a pile of smoke concluded that they blast had hit home. Ash waited for the things to come.
Vegetto had landed at Ash's house, and told them everything. He said them to watch T.V., because this would not go unnoticed. And he was right. A few reporters had assembled around the island. Vegetto flew through them and saw Ash floating. He was ready to fly up to him, when he sensed something coming. "Damn, I didn't beat it! I hope Ash did, because if he didn't, we have a HUGE problem!", he thought. He flew to Ash, and looked at him. Ash said what Vegetto thought. "I couldn't kill it. My last attack was to weak to finish it off.". Vegetto nodded, and floated alongside of him. "We have more trouble coming. Can you sense it?", he asked. "Yes. This is gonna be a problem. And this may seem strange, but even if we are stronger than now, and surpass our powers, we cannot beat them when they merge. This is a serious problem, indeed.", Ash said. Vegetto grinned. "Well, we don't know if we don't try, don't we?", he said. He had a little plan, which could cost him his life. "Let me fight them first.". "What are you saying? You will need my help!", Ash said. "I'll tell you when you can fight. I'll wore him out, so you can finish it off.", he said. Just at that moment, the creature smacked down by Ash flew up in front of them. The one that Vegetto fought came in shortly after. They stared them down. "Shall we, brother?", one of them said. "Of course brother. Nothing can stop us.", the other answered. Ash and Vegetto waited for the things to come.
The two creatures touched eachother, and a blinding flash followed. Ash and Vegetto closed their eyes. When the could see again, they saw the result. In front of them floated a creature, which almost looked the same, except it was a little taller, more muscular, and his eyes were now dark blue. And it was extremely powerful.
