Everyone who was fighting, literally froze. They turned their heads to the people who just came, and they all shouted either 'Kakarot' or 'Goku'. Vegeta could tell that this person was Kakarot. He had a tail after all, and he definitely wasn't Celeron.
Piccolo had died while Celeron went to Goku. He had sacrificed himself for Gohan. Celeron wan't standing next to Goku when he teleported so nobody realised he was back to the sitting spot he was in before.
Goku then powered up to his 100%, making debris float into the sky.
"Vegeta, what does the scouter say about his power level?"
"IT'S OVER 17,000!!"
"What?? 17,000?! There's no way that can be right? Can it?!!"
And then- Goku fought Nappa and easily knocked him out, well at least he thought. When he turned around to Vegeta, Nappa went running towards Krillin and Gohan to kill them. Goku panicked and used his Kaioken to boost his speed. He basicslly teleported to Nappa and kneed him in the back, breaking his spine.
Goku grabbed Nappa and threw him in front of Vegeta. Nappa was begging for mercy to stay alive but Vegeta just threw him into the air and destroyed him with a single blast.
Goku told Gohan and Krillin to go to Kame House which they did. Goku and Vegeta went to some place further away so the dead bodies wouldn't get damaged. But both of them stopped mid-air when they heard a voice say, "Wait! Goku! Show me your Kaioken one more time?"
"But Celeron, that's going to waste my energy!"
"Don't worry, I'll give you a piece of a senzu bean after."
Goku quickly used Kaioken and punched the air a few times before turning it off. "Was that okay?"
"Yes! Thank you, here catch." Celeron threw the piece of senzu bean and walked away, completely ignoring Vegeta's 'rivalry' glare. Goku ate the senzu and then went to Vegeta to fight, while Celeron went a bit further away.
Celeron slowly copied what he just saw. And then! He was encased in a glowing, red aura. "Kaioken!" He shouted. "Kaioken x2!" "Kaioken x20!" This had some strain, but it was nothing much for Celeron, it was probably because his body wasn't used to the technique! Celeron had suppressed his Ki to 5 at the start, so now it was 100. Luckily, the only person who noticed was Goku with his Ki sense.
Celeron then started to go from Kaioken all the way up to Kaioken x20 so he could get used to it more. Just because he had a strong power level didn't mean that he was used to the technique. Slowly, he got adjusted to the technique and was able to effortlessly use Kaioken x20. He didn't really want to try above x20. He felt like the strain would multiply by a crap ton! Maybe that's why Goku didn't use above x20? Apart from the x100 in the Lord Slug movie, but that's non-canon.
Celeron then thought of something. He tried to feel the tingling in his back for Super Saiyan. It took him a while, since he had to be a 'gentle' Saiyan to have more S-Cells and Celeron was anything but gentle. When he focused his power into his upper back, he felt something and then he added more power. And then he felt like he could 'multiply'. He knew that it was Super Saiyan! Well for him, it was probably some sort of Legendary Super Saiyan.
Anyway, he definitely wasn't going to do it here! If he used his full power, he would probably destroy the whole wasteland! Celeron then remembered, Goku and Vegeta were fighting! He excitedly walked over to see what was the outcome of the fight where he had buffed up Goku and Vegeta.
And when he got there- he saw Krillin standing over Vegeta, ready to kill him, but the injured Goku was talking about sparing him and reforming him and all that. Celeron was so confused... what happened? Wasn't this EXACTLY like the anime? What the hell?! What happened to his 'interesting outcome'?
A while ago...
Vegeta turned into his Great Ape form and laughed at Goku who was screaming in pain in his hand. He squished him and crunched his bones. But then! Yajirobe came out of nowhere and just sliced his tail off!
Vegeta dropped Goku as he turned into his human form. He was breathing heavily, he was absolutely furious. But instead he laughed, "I can still kill you all in this form!"
And then- he got a Spirit Bomb to the face, Goku had given it to Krillin to use it at the right time. Vegeta got injured but not by much. He got even more angry now, veins popping out of his head. Then he walked up to Gohan who was unconscious on the floor! And he saw that the little shrimp had regrown his tail!
Vegeta would be able to beat Gohan's Great Ape form even in his injured state but he would have to use a lot of his energy! So he was about to cut Gohan's tail off, it was too much trouble. And then! Yajirobe, the party-pooper, once again cut Vegeta on the back! Vegeta hunched over, he was absolutely delirious with rage now. This fatty! He just wouldn't stop getting in the way!
Vegeta walked up to him and kicked him in the face, making him fly straight into some rocks. Vegeta walked up to the already bleeding Yajirobe and started to repeatedly punch him in the face. Krillin just watched on in horror.
Then, as if remembering something, Vegeta ran to Gohan, who was already half way through his ape transformation. A few seconds later, Gohan went crazy and started to smash everything! And from his tall height, Gohan was able to see a shining, red aura in the distance. He found it a very 'appealing' thing to destroy. So he walked that way. Vegeta was confused at why Gohan left. But he breathed in relief that he had left.
"HAHA! Your ape has ran away! What will you do now?!"
"Gohan! Come back!"
Krillin shouted but Gohan couldn't hear his feeble voice, he was already far away now. And then Goku's voice sounded out, Gohan somehow heard it this time. And Gohan paused as he turned around and started to smash his way to Vegeta. Vegeta's eyes opened in horror as he ran away, he wasn't sure if he would win with that cut on his back that he got from the samurai.
But , of course, Yajirobe was still trouble even after he was left bleeding on the ground. Vegeta would have gotten away, if it wasn't for the meddling katana that he just cut his leg on in his panic! He wasn't paying attention to anything but the ape. And now he had an injury on his leg! He was doomed! He then tried to think of something... and he did!
He tried to use Krillin's Destructo Disk to cut off it's tail. And it did! He was lucky that Gohan literally walked into it. Vegeta would have missed if it weren't for the mountain on Gohan's left that he had to smash.
Back to the present...
After Vegeta had left in his space pod. Celeron asked for a recounting of the events from Krillin. And he got it. Celeron was so confused. Such bullshit coincidences! He never really got his 'interesting outcome', it was exactly the same! But he knew that there should be some big differences when they go to Namek! Vegeta and Goku will be much stronger, which also means the Z-Fighters will get stronger. Celeron realised though, Goku and Vegeta would probably catch up to him soon if he didn't start training! Goku would get that absurd Zenkai on Namek, which will probably be even more absurd since he has a higher power level. Same with Vegeta, he has a higher power level too!
Celeron wasn't going to waste senzu beans on these people. So he just grouped them up and picked them up, one on his back, and another on each shoulder. He left Yajirobe, the guy would probably get a senzu bean from Korin anyway. Celeron dropped them off at Wukong Hospital. He just left them outside as he didn't want the hassle. But then he heard a voice whisper, "Thank you."
He smiled as he teleported to Bulma in Capsule Corporation.
