I explained a bit more about my plan and we all headed to Capsule Corp to discuss our options.
(A few minutes of flying later)
All the Z-Fighters were gathered at Capsule Corp and were all standing across from me so I could explain why I was going to Namek.
Goku had immediately requested that he go with me so we could train together as he wanted to figure out how I got so strong and honestly, I didn't find it to be a bad idea.
I then explained to him about our special ability of a Zenkai boost and said that was the main reason aside from intense training that I got as powerful as I did.
The Zenkai is consistent, but it loses it's true effectiveness after one enters the billions in their power level.
It will still increase, but will provide a negligible boost in power as our power would be so strong, but an increase in power however small, is still an increase.
Goku had a look of understanding, as did everyone else who'd fought him before and they noticed that he did get stronger extremely quickly but had the biggest improvement after his defeat of King Piccolo which was his first true Zenkai.
I realized that including Goku in my travel training could boost his strength exponentially. And having someone like Goku as a sparring partner even if he couldn't do any real harm to me, was still invaluable.
So with a lot of discussion, it was decided that Goku and I would take my ship and travel to planet Namek training the entire way.
The other Z-Fighters agreed to also come to Namek but would be taking a different ship which they took in the original story.
Before we left though, I had to give Goku and Gohan the Zenkai that they hadn't gotten from fighting the Saiyans and I told them I could make it quick but unfortunately, it wouldn't be painless.
Goku agreed immediately as he knew the stakes that we were dealing with, but Gohan was unsure. I told Chiaotzu to hand me the bag I handed him to which he agreed and I opened it up to show 3 senzu beans.
Goku then handed me the 2 he got from Korin and we now had a total of 5 like I did before Yamcha and Tien were given one.
Eventually, we all went to another mountainous area and all the Z-Fighters were there wanting to see my full power as I told them I'd be using it to make the Zenkai as quick as it could be.
"Get ready you guys. Goku and Piccolo have already sensed my full power, but you guys haven't. Try not to faint from shock." I explained.
The Z-Fighters thought I was joking but Piccolo and Goku knew the truth.
"Haaaah!" I shouted quickly and released my full power in a controlled manner so as not to destroy my surroundings, an easy feat with my enhanced Ki control.
All the Z-Fighters felt my power and Chiaotzu actually did pass out and Gohan almost did.
"Alright Goku, you first. But I would suggest you use your Kaioken to your highest level before I do anything." I said and he stepped forward.
"Why do I have to use Kaioken?" He asked curiously.
"The more damaged your body is before being put in its near-death state and recovering, the better. So if you want to get stronger faster, that's the best way. Not too mention, it'll increase your resistance to the strain of using Kaioken if it is as you described." I explained as Goku had discussed a little bit of his training on King Kai's planet during our flight to Capsule Corp and back to a desolate area to conduct the Zenkai.
Goku then began to activate his Kaioken multiple times in a row until he hit Kaioken times 4 and I told him to try and go for one more to Kaioken times 5 as that was higher than he went in his battle with Vegeta.
Goku complied and his power instantly shot up by another level and I could hear the strain in his voice when he was speaking and I saw him double over in pain and I knew it was the perfect time.
"I wish I could say this isn't going to hurt, but I'd be lying." I said before creating a Ki Sword and I stabbed him completely through his body, my Ki blade coming out of his back.
Goku vomited blood and collapsed on the floor and was bleeding heavily after I dissipated my Ki blade. I then attacked him with my Ki Lightning attack and he began to scream in agony before he went still on the floor.
The Z-Fighters thought I went too far and killed him until they saw his body twitch, but he would be unable to chew the Senzu bean himself.
I quickly opened his mouth and pushed his jaw so he'd chew the bean and after a minute or so, Goku quickly jumped up feeling better than ever.
"Whoa, you weren't kidding I feel amazing. Hey Bulma, what's my power level right now?" Goku asked.
"Wow, it's 12, 240!" Bulma said excitedly.
That was over a 33% increase which is good as he didn't really get a Zenkai in the original story as most of his wounds were self-inflicted through a Kaioken overload and he wasn't in a near-death state but he did have a massive amount of damage inflicted on him which is why in the original story he had to heal until Yanjirobe arrived with more Senzu beans
After testing out his power a little, Goku turned to look at Gohan.
Gohan instantly got scared as he had seen his dad in immense pain and he didn't want to experience it himself.
Gohan started to run away and I knew that since he didn't go through what he did against the Saiyans due to my interference, he was still the scared little boy he was and I'm not in the habit of traumatizing little kids.
I quickly flashed in front of Gohan and he started cowering.
"Don't worry kid, I can see this isn't something you're ready for and you might never be ready to willingly let yourself be hurt." I said as I rubbed his head.
I knew Gohans potential, he could go very far with just training and he may get a natural Zenkai in the future.
I actually felt really bad, I was acting like Goku for a moment acting like it's completely normal to put a child through what Goku put him through.
Gohan cried and ran to his dad.
'Am I that scary?' I questioned internally feeling a little aggrieved about his reaction.
But I suppose he did just watch me nearly kill his dad so his reaction is valid.
