Chapter 20

Once I returned back with Broly, I continued to help him in terms of his psychology as well as helping to tutor Gohan while training all of our group at the same time minus Goku when he returned. And I only made sure to train Broly if he wanted to, which was a bit often, but he did have his days he didn't want to train. I knew that having him on Earth was a huge risk and that he may become a future villain, but he wasn't evil. He just had a vendetta against Goku. But every single day I worked with him he started to get calmer and calmer every time that I mentioned Goku's original name of Kakarot until, at some point, just a month before the Androids would arrive, he finally was able to stay absolutely and positively calm whenever I mentioned Kakarot or Goku's name to him.

"Okay, now that you've finally learned how to control your anger at Goku, we can finally move on to the next step. It's going to be a bit tougher, just so you realize," I said to Broly, who smiled contentedly at me.

"Of course... I'm ready, Master," he said to me. It was odd that he called me his master when all I did was help him control his emotions and train him a bit, but I didn't mind it. He was actually quite the gentleman when you really got to know him, which was an honest surprise I didn't see coming from the buff Super Saiyan.

"Okay, Broly. The next step is to be in Kakarot's presence. We will go to a secluded area that I have told Goku to meet us at just in case things may go bad. Just a small bit of precaution, just to clarify," I said to him, Broly nodding at that as well. "And then I will try to have you engage in a training session with him if you can keep calm around him. If you can effectively train with Kakarot for 1 hour straight without a single act of aggression, then you've proven you can handle your anger enough to the point I can take off your restraint device," I smiled at him, the last bit making him a bit surprised.

"M-My restraint device?... Are you absolutely sure?" he asked in shock.

"If anything were to go wrong if I remove it, I'll just place it back on your head. Keep in mind that I'm still the stronger of us two even if you do go to full power," I smiled at Broly, him looking at me like I was crazy, but still nodding all the same. "Okay, I'll warp us away to the area Goku agreed... the same place he first fought Vegeta," I smiled as I warped both of us away and to the location, it being the same dusty desert we had been to before. And upon arriving, Broly looked at Kakarot and I could feel some kind of tension, but he sighed and put on a smile. He was calm, just a bit uneasy.

"So you're Broly, right?" Goku smiled at my big bud, Broly smiling and walking forward slightly, turning himself into his blue-haired Super Saiyan form, Goku in awe at his power. "You're quite tough, even when not at full power, I will admit that much. And about the past, no hard feelings, right? Besides, I can't remember anything for the life of me," Goku smiled, Broly smiling at that.

"Master Trixie... already told me," Broly smiled at Goku.

"Master? You actually have a student, Trixie! That's so cool!" Goku smiled.

"What can I say? I know talent when I see it and even though he is holding back, I can sense that his power right now is equal to yours in Super Saiyan form. At full power, the androids won't stand a chance," I smirked.

"So 1 hour, correct?" Goku smiled.

"One hour. Then, if all goes well, we can finally see Broly's true power," I smirked as Broly put up a battle stance and smiled at Goku.

"I'll go easy on you," Broly smiled confidently. He was being absolutely calm. Just had to hope it stayed like that.

It was a complete success. For the entire 1 hour that Broly trained with Goku, he never once did anything malicious nor thought anything malicious towards Goku at all. Even when he thought of the bad memories, he simply shook his head and looked in my direction to calm down. He was much more calm when I was around, that much was for sure.

"Okay, the hour is up and you're still as calm as ever. Now for the moment of truth. Time to see your true power and see if you can control it," I smiled at Broly, him smirking and kneeling to me so I could take off the headdress he wore on his head. I then placed my hands on the device and took it off of Broly's head, Broly gasping when I took it off completely, but him recovering as I noticed his regular Super Saiyan hair turn into its absolute golden state and he gained much more buff all over him to match. The only difference between his current appearance and in the movies? He had his pupils in his eyes and he didn't look angry. He looked completely calm even in full power.

"What incredible power! It's amazing!" Goku said in surprise and astonishment as Broly then looked at Kakarot and smiled, poking his nose playfully.

"You are officially a changed man, Broly. You can control your anger completely now! Your parents are going to be so proud of you!" I smiled at him.

"My parents... yes... it is about time that we visit them again, isn't it?" Broly smiled.

"Yes, it is. Would you like me to warp us to their location?" I smiled at Broly.

"I'd like that, Master," Broly said. Always a man of few words. I then grabbed his clothes and warped us both to Paragus and Letticia's location, them looking shocked by our sudden appearance in an area that looked to be a regular house filled with simple necessities and knickknacks.

"Oh my!... What the... son? Is that really you?" Letticia gasped when she saw Broly, her shock plain as day when she saw the restraint device still in my grasp and that Broly was in his full power state.

"Incredible... You actually frigging did it, Trixie... We're forever in your debt for this..." Paragus smiled as Broly approached his parents and he hugged both of them with one arm each. He was actually bigger than both of them and yet Broly was still as kind as he had proven himself to be.

"You're welcome. And there really is no debt to be paid to a ghost, right?" I smiled at them.

"Still, we can't thank you enough..." Letticia smiled as she actually started to cry silently. "Thank you... really, thank you," Letticia sniffed in a large booger.
