DRAGONBALL SUPER, GT OR ANY OF THE MOVIES ARE NOT CANNON
In Age 774, the universe comes under attack by the terrifying evil that is the ancient demon Buu. It is only through the sheer determination of two Saiyan warriors, Vegeta and Son Goku, that the evil Majin is vanquished and wiped from the universe. And so followed a peace the likes of which Earth had never known; over the course of one hundred years, the two warriors faded into legend. Their friends scattered about the Earth, all of them finding peace and happiness. Goku's eldest child, Son Gohan, grew to become a highly respected scholar. He wrote a book entitled Groundbreaking Science, which introduced the public to the concepts of ki control and the advanced martial arts that only a select few warriors had ever utilized.
Long after his death, Master Roshi lives on in Krillin's New Turtle School; the spike in interest concerning advanced martial arts convinced Krillin he should continue his Master's legacy. Inspired by his friend's success, Tien Shinhan opened the New Crane School; the two are widely regarded as the best schools on the planet, and friendly rivalry between the two has developed. Both Krillin and Tien have trained an entire generation of powerful martial artists, and they have two students they see enormous potential in.
As for Son Goku and Vegeta, the two warriors disappeared from the public that they had once blended in with; after the death of his wife ChiChi at a ripe old age, Son Goku bid his family and friends goodbye and good luck, and disappeared.

By that point, Pan had become used to waking up early in the morning, only to find her grandson training diligently outside. She smiled when she peered out the window over the sink, watching the fourteen year old dashing from side to side, punching and kicking with a speed that Pan wished she had when she was a teen. Of course, Pan wasn't trained by the Turtle Master like Gokan was; sending him to the New Turtle School when he was eight had been a difficult decision, as his parents had not wished for him to become a fighter; however, when they both perished in a terrible accident and the boy came under Pan's care, she saw his incredible aptitude as a fighter, and immediately contacted The Turtle Master, Krillin; he was an old family friend, and though saddened to hear of the two deaths, he was delighted to teach the boy. In the years since, Gokan grew remarkably, both as a fighter, and as a person. By Pan's estimation, he has the potential to be powerful like her grandfather Goku, and the intellect of her father Gohan.
"Gokan! Come inside and get ready!" She called out the open window. She set up his breakfast on the table, and went back into the kitchen to get her cup of tea. When she returned, he was already feasting ravenously on the food she had prepared.
"How is it?" She asked with a smile.
"Delicious!" He said through a full mouth.
Pan made an extra large breakfast this morning, as today was the day of the 64th Tenkaichi Budokai; the tournament was held every five years, and this was the year that Krillin had elected Gokan as an entrant. Pan had felt worried at first- Gokan was only a teen of course- but he had shown so much potential, that she knew he would make it far, if not win it. Gokan let out a loud belch, before looking up at his great grandmother. He paused for a moment, thinking deeply, before his eyebrows raised dangerously high and his mouth widened into a face splitting grin.
"It's today, isn't it? Oh yeah it is!" He said with building excitement. He jumped out his chair. "I have to get ready! Did you clean my gi?" He yelled as he ran to his room.
Pan just smiled and shook her head in amusement.

Krillin arrived about thirty minutes later, hopping down from Nimbus.
"Is he prepared?" He asked Pan after they had exchanged pleasantries.
"Of course he is. I've never seen him so excited! He's calmed down since he put on the weighted clothing, though." Pan said, and Krillin chuckled.
"He'll thank me later for that,"
"Master Krillin!" Gokan said, running outside and stopping at Pan's side, bowing to his teacher. "Thank you so much for letting me fight in this tournament! I very much look forward to facing the competition." He said excitedly. "Although, the weighted clothing is slowing me down a bit,"
"It's only one and a half tons, I hope you aren't having trouble yet." Krillin said with a smirk. Gokan's posture straightened.
"No sir, of course not! I could fight all day in these!" To punctuate his point, Gokan began throwing fast punches and kicks in the air, causing Krillin to chuckle.

The area outside of the arena was already crowded with people; children of all races- human, Namekian, Majin- going up to vendors and purchasing food and memorabilia, some finding friends and family and chatting excitedly about the tournament. Krillin, Pan and Gokan jumped down from Nimbus, and Krillin sent it off. They began walking through the crowd. Gokan gaped in amazement at the building. It was finally dawning on him that he would be fighting in the biggest tournament in the world, and he wouldn't even be in the Junior Division!
"Master, this is all so amazing! Is it like this every year?" Gokan asked his teacher.
"I don't think it's ever been this packed before- it seems like ever since your great-great-grandfather taught the world about advanced martial arts, the crowds have been growing every year!" Krillin's eyes scanned the building. "They aren't letting the fighters in yet, but they're letting in the audience. Would you like us to wait with you here?" Krillin asked his protégé. Before Gokan could reply, a familiar voice spoke behind Krillin.
"Krillin."
The Turtle Master turned around; Gokan was almost equal in height to his Master, but the few inches difference caused to teen to have to crane his neck to see who had spoken. Gokan had seen him a few times before; the man was dressed in a green and yellow robe; he lacked any amount of hair on the top of his head; and, most striking of all, he had a third eye, set in the center of his forehead. This was the Crane Master, Tien Shinhan.
"Tien." Krillin replied tersely. Gokan raised his eyebrow, and his eyes fell to another person at Tien's side; he looked as though he was about the same age as Gokan, give or take a few years; his hair was dark brown, and his irises were blue; he was wearing a green and red gi, he Crane School kanji displayed large and proud on his chest. He was staring at Gokan with an almost unsettling intensity, but Gokan stepped out beside Krillin, his face straightening and returning the intense glare defiantly.
"This is Beat. He is my top student." Tien said proudly, indicating the boy at his side that Gokan was staring at. "Much like your entrant, Beat comes from a rich heritage…. but he excels with it, as opposed to coasting on it." Tien said with a smirk.
Before Krillin could reply, a man began to calling for the entrants to make their way into the training room. The corners of Beat's mouth curved into a small smile, before his broke the glare and turned on his heel, walking to the entrant's area backstage. Tien turned and walked to the audience area, disappearing into the crowd. Pan came down to one knee, putting her hands on Gokan's shoulder.
"You have this, okay, Gokan? You have achieved so much of your potential. Remember what Master Krillin said, correct?" Gokan nodded his understanding.
"Control and channel my rage." Gokan said, and Pan smiled and nodded, kissing him on his forehead.
Gokan took a deep breath, and turned towards the entrance to the fighter's area; Krillin placed his hand on Gokan's shoulder and gave him a nod of encouragement, one which Gokan returned.
He walked through the doorway.
