After their battle Guy and Vegeta haven't seen each other since. Mainly because Vegeta was still training hard to soon surpass Goku and Guy. Meanwhile, Guy was spending the past few months training, tinkering with tech, and just spending time with family and friends. Even with all the hard training he did Guy still went to go see his Grandpa a decent amount. Make some inventions with Bulma and spent time with everyone if they weren't busy.
One of the bigger things that have happened during this time of peace was his power level soared to 7.5 million. It was only a 2 million boost in the past few months but as Guy kept getting stronger the rate he improves also increases. He took full advantage of that and now he is always under 500 times gravity for regular life and higher for training. Guy could have easily raised his power level even higher but he took time to rest for training because even he knows too much training is bad for the body.
Guy flew towards Chi Chi's house while carrying a box with a relaxed look on his face. He arrived and knocked on the door to only hear from inside "Come on in"
Guy opened the door to see Chi Chi making a big lunch. He waved to Chi-Chi who said with a happy smile "Hey Guy glad your on-time oh and I see you brought some milk"
Guy gave her a grin as he said "Yeah took a lot longer than I thought it would. Some lady was screaming for the manager so I just went to self-checkout and got here just in time"
ChiChi nodded along as she continued making lunch while Guy offered to help. But she shooed him off and said "Gohan was looking forward to you coming over because he had a question for you."
Guy was a little surprised but he went to Gohan's room and saw he was doing his homework. Guy knocked on the door and asked with a smile. "Hey, Gohan you needed to ask me a question?"
Gohan turned around and saw Guy he had a big smile on his face as he got up and ran to Guy "Uncle Guy glad your here I have a quick question to ask you"
Guy was giving Gohan his full attention as he motioned him to ask it. Gohan was a little nervous for asking but his curiosity got the best of him. "Could you please show me your full power?"
Guy didn't expect that from Gohan but he still asked with a smile "How come you want to see my full power Gohan?
Without missing a beat he said with no hesitation "I want to see your full power because you were so strong as you defeated Vegeta without using any of your forms. I could vaguely sense your power when you were training but I want to see how strong you are"
Guy saw the determination in his student's/nephew's eyes and he said with a casual tone "Sure Gohan I will show you my full power but we might need to go to a deserted place. I don't want to see your mom go super Saiyan on me for destroying her house."
Gohan laughed at that a little because he saw how angry his mom could get sometimes. Like the time she got a tutor for him and he said some things about his dad. ChiChi threw the tutor out the window into a tree. Shortly after deciding what they were going to do. Guy went to ask ChiChi how much time until lunch was ready and she said "18 minutes"
Guy nodded and told her they would be back before then. With little time Guy picked up Gohan and flew at a fast speed to a deserted mountain range a few miles out from anyone nearby. He put Gohan down and flew a good 15 meters away from Gohan and said with a grin. "Are you ready Gohan?"
Gohan flew up in the air ready to see how strong he was. He nodded with a determined look while Guy couldn't stop grinning at his student's ambition. He touched a button on his watch as his gravity went back to 1g. The sudden disappearance of the massive 100,000 pounds of weight off his body. Guy enjoyed the weightless feeling it had from taking off all that extra weight. He took a deep breath as he used his great energy control to rise to his max power pretty fast.
A large golden aura emerged from Guy as he looks at Gohan who is still shocked at how strong he is even only at his base form. "This is my max power for my base form"
Gohan broke out of his stupor and looked intently to watch. Guy opened the first gate as his power skyrocketed by ten times. His large golden aura grew larger as Guy said again "This is the first gate"
He gripped his fists as he sends ki to the third gate. His skin turns bright red as veins start to appear on his body. "This is the third gate!"
Gohan saw how the large golden aura suddenly grew massive. He could feel the wind pressure pushing him back but he stayed mostly still as Guy kept opening more gates. Gohan saw Guy's eyes go completely white as his golden aura had a tint of green to it as he heard Guy yell out "SIXTH GATE THE GATE OF JOY!! OPEN!!"
A massive air current was produced from the raw power produced from Might Guy opening the gate. Gohan was struggling to stay air-born but he kept focusing as he heard something he didn't expect to hear. "I can go even further if I wanted too but my body would be sore for a good while. But I got something to compensate for that"
Gohan saw as the massive golden aura suddenly spiked again as bright yellow lighting started to arch of Guy's body and across his aura" HAAAAAAA"
Guy roared out as he activated Godspeed. This is the first time in a few years since he has tried to go all out like this to see how powerful he can become. The feeling was almost intoxicating but unknown to Guy who was focusing on powering up the planet was shaking due to the massive energy waves Guy was giving off. In a random dojo an older man who some may know as Mr satan was praying for dear life as he kept falling over after standing up "OH MY GOD PLEASE MAKE IT STOP"
While Mr. Satan was holding on for dear life. All across the world, the Z fighters were sensing the massive energy Guy was emitting. 'Is that... Might Guy?'
"GODSPEED!!" Guy's already massive power level just got multiplied by ten because of his technique. He saw Gohan was being blown away from the energy he was emitting so he closed all the gates and godspeed as he caught Gohan. "Are you doing ok Gohan?"
He took a few deep breaths as he nodded "Yeah I am. Just was shocked at how strong you were"
Guy gave him a big smile and a thumbs up "Don't worry Gohan you will easily reach this level if you keep training hard. Always remember Gohan with the power of youth anything is possible."
As Guy was giving that motivating speech to Gohan a short Saiyan prince was gripping his fists in a desert plane. He fell to his knees as he started to punch the ground as he cried out "I WANNA, I WANNA BE A SUPER SAIYAN. I WANNA WANNA WANNA WANNA"
Through his desperate attempts, he suddenly transformed into a Super Saiyan. Vegeta stood up and laughed out loud as he finally became the legendary super Saiyan. From a distance, it almost looked like he was a... Golden Warrior...
