Goku looked at his current surroundings, and quickly realized something.
He nervously gulped and asked the trio, "Is it okay if we move somewhere else?"
Mafin spoke up, "Sure, why?"
"Gohan's currently having his study session, and I kinda don't want to disturb him."
21 smiled, "That's understandable, Goku. All three of us wouldn't want to disturb him either. Especially when it comes to education."
Mafin nodded in agreement, and Begu exclaimed, "Yeah! What she said!"
Goku sighed with relief, "Okay, good. Because when I get into fighting, I get INTO it! Which means this match could get a little...destructive."
Begu smirked, "Hey, makes it more of a challenge for us."
Goku nodded and thought, "Now let me see if there are any distant locations devoid of people around..."
He put two fingers to his forehead, and began searching for a new location.
After a few seconds, he smiled, "Okay, I got it!"
Goku turned to the trio, "There's a distant rocky wasteland several miles away. I can get us there quickly with Instant Transmission."
21 thought, "Rocky wasteland? Could it feature the same laboratory that I was discovered in? If so, then that gives me an idea..."
The Saiyan happily said, "Grab on you guys."
The trio put each of their hands on Goku's shoulder, and the Saiyan instantly teleported away.
The group arrived at the rocky wasteland.
Goku grinned, "Sweet! Now, we can start!"
21 turned to the duo and said, "Guys, I'm going to see if that old laboratory you found me in is around here."
Mafin nodded, "Alright. Good luck with finding your information, 21."
The android said, "Thank you. And please be careful out here."
Mafin calmly said, "Of course."
Begu added, "We got this!"
21 smiled, and began flying away from the three fighters.
The duo and Goku proceeded to float several feet away from each other.
Goku stretched his legs and said, "I hope you boys are ready for this."
Begu grinned, "Heck yeah we are. This is gonna be exciting!"
Mafin nodded, "I agree! Having a match with the one who took down Frieza is an honor!"
Goku chuckled, "Thanks Mafin."
The three fighters then patiently stared one another down.
A second later, they all flew towards one another, and the match began.
The duo sent constant jab after jab on the martial artist, who kept on blocking and dodging.
Goku was obviously holding back of course, as he really didn't want to kill the duo using his Saiyan strength.
The three fighters quickly took their battle to the sky.
Afterwards, Mafin (using his 'Heating Hands' technique) balled his hand up into a fist and uppercutted the martial artist's jaw. Following this, he roundhouse kicked him in the stomach.
Then, Begu headbutted Goku in the face, and sent a palm strike straight to his neck.
Goku hacked out some saliva, and smirked, "Not bad. You two make a decent tag team."
"Thanks!", exclaimed Mafin and Begu.
Goku said, "Now watch this."
He took a deep breath and shouted, "KAIO-KEN!"
As he began charging up, a crimson aura engulfed the Saiyan's body.
Mafin and Begu's eyes widened when they sensed his energy.
"His power is rising fast!", said Mafin.
Begu exclaimed, "Yeah! No duh!"
Before the duo could do anything, Goku teleported behind them, and sent several rapid fire punches to the both of them.
He finished off his attack with a double fist strike, causing the boys to fall and crash onto the ground.
The duo quickly hopped to their feet, and looked up at Goku.
Begu shouted, "NOW TAKE THIS!", and unleashed a large amount of ki blasts on Goku.
They were all instantly swatted away by the Saiyan.
Begu's eyes widened and muttered, "Well, crap. I was sure that attack would work."
"So, it's gonna be like that, huh?", thought the Saiyan.
Goku then cupped his hands together, and slightly turned his body around.
He chanted, "KA...ME...HA..ME..."
When he said this, a blue ball of ki energy began forming in his palms.
Mafin exclaimed, "Wait a minute! Isn't that the Kamehameha attack Krillin was talking about?!"
Begu exclaimed, "I guess so!"
Mafin nervously asked, "What do we do?!"
Begu replied, "Let's just fire our own beam attacks at his!"
The duo charged themselves up, and they unleashed two full power energy waves at Goku.
"HAAAAAH!", shouted the Saiyan as he fired out a massive blue ki beam.
The three attacks clashed with one another, and a beam struggle emerged.
However, after a few minutes of this, Mafin and Begu clearly fell to the losing side as Goku's Kamehameha started to overpower their energy waves.
Mafin stammered, "It-It's too much power! We're going to have to avoid the attack!"
Begu shouted, "Let's dodge it! Quickly!"
Mafin nodded and the two of them flew out of the way.
The blast hit the ground, causing a gigantic explosion.
The explosion soon faded, and all that was left was a large crater.
Mafin and Begu flew up next to Goku, who gave a thumbs up.
"You two were pretty good! Krillin's been teaching you well.", said the Saiyan.
Mafin smiled, "You were great as well!"
Begu playfully smirked, "But you were holding back, weren't you?"
Goku nervously chuckled, "Y-Yeah! I just didn't want to risk killing you two."
Begu shrugged, "Meh, that's fair."
"Besides that, I still think you two did good. You seem like promising fighters."
The duo happily gave one another a fist bump.
Goku smirked, "Want to go another round?"
Mafin and Begu held one another in excitement, and they both shouted, "YES!"
Meanwhile, 21 flew around the rocky landscape for a bit, before coming across a familiar cave entrance.
"Found it.", thought 21.
She flew inside, and walked past the destroyed android pods.
The android saw various blueprints strewn all over several metallic desks.
She narrowed her eyes and saw a bunch of files underneath one of the blueprints.
21 grinned with excitement, and immediately grabbed them.
The android quickly flipped through several documents about many different androids, before stopping at her own document.
21 examined it carefully.
After a while, she thought, "I don't believe this. There's nothing written about my past life on here."
At that moment, she heard an explosion coming from outside.
21 thought, "I better let the guys know about this..."
