Raditz glared and crossed his arms as he met the eyes of his visibly seething brother. "Kakarot! Why have you been so impossible to reach all this time?"

"Why do you think I would talk to you, after everything you've done?" Goku replied with control, though his expression didn't soften in the slightest.

Raditz clenched his teeth with annoyance at his brother's relentless pursuit of retribution for those worthless lives. "You're still-" Raditz cut his complaint off as his brother growled and bared his teeth at the unwelcome response with which Raditz began. "Look, I understand why you're upset about the kid." Raditz relented, tossing his hair and looking away from Goku with discomfort. "I'm sorry I had to kill him."

His eyes lowered to the ground as he admitted as much. Raditz truly was sorry about that. He realized what a mistake it was in regards to their rebellion against Frieza, and he attributed his brother's only reasonable grudge to that death alone. Goku frowned somberly back at Raditz in a prolonged, wordless silence.

"He put up a good fight, though. You should be proud, Kakarot."

Goku's demeanor suddenly softened as he gawked in open-mouthed disbelief and his eyes widened in shock at Raditz's assertion. Then he contorted his brows deeply in bewilderment. "G-Gohan...fought you?"

"Yes. As a matter of fact, he put you to shame, once he decided to show me his power. But he should have known better than to fight against me. I would have taken him from Earth with me if he hadn't." Raditz frowned somberly. "He faced his death like a true warrior. Like I said, you should be proud."

Goku was staring back at Raditz in awe of his revelation, but then he glared at Raditz furiously. Raditz only further cemented in Goku's mind what he'd lost. "You mean proud of my son's strength that I'll never be able to see for myself? Proud to live on when everyone I ever cared about is dead? Proud to be stuck out here with Frieza, like my brother? That there's nothing left in this world to protect?!"

Raditz's eyes widened in alarm as he realized he'd made a mistake. His attempt to make peace with his brother only seemed to make things worse. Raditz bared his teeth in frustration. His brother had no business reacting that way. If it weren't for Raditz finding him, Kakarot would have spent his entire life ignorant of his heritage and stranded on a backwater planet. Kakarot would never have the chance to avenge their race, their planet, their parents, if Raditz hadn't clued him in. It wasn't Raditz's fault that his brother was living in blissful ignorance before Raditz came along.

"Maybe some things are more important than your precious little Earth."

"Like what? The family we still have left?" Goku replied acidly as his eyes narrowed and he shifted forward in an aggressive position.

"Like our pride." Raditz said with a glare. "The rest of the Saiyan race may be dead, but we live on. It is up to us to show the rest of the universe what a proud and mighty race we are."

Goku removed his fixed gaze from Raditz to observe the appearance of another energy he sensed approaching. He frowned when he realized who it was. The sensors on both brothers' scouters detected the change as well, beeping hastily as they registered the extremely high power level that could only be one person, along with another.

Goku scoffed as he looked at Raditz again. "Some proud race. I now know exactly what you've been doing while I was living on Earth. The only thing Saiyans are good for is killing at his bidding."

Goku nodded pointedly towards Frieza as he and Dodoria finally reached them, stopping at a distance to observe the fight from the sidelines.

Frieza smirked at Raditz as Goku frowned solemnly at his brother. "That, and killing innocent people just for the fun of it. Like you killed all of them. You're not sorry."

Goku's frown deepened as he slowly shook his head in disappointment and raised his fists in front of himself, taking a hostile stance towards his brother. Raditz growled with frustration as he startled and hurriedly raised his fists as well. Frieza smiled smugly at the sight, chuckling to himself.

Raditz's eyes anxiously darted between the hostile expression of his brother and the casually confident ones of Frieza and Dodoria on the sidelines. "So now what? You're favoring them over us?" He asked Goku facetiously, catching a flicker of a wary glance from Goku in Frieza's direction as he spoke.

Then Goku raised a brow at Raditz, answering with a subtle shrug and a frown. "Not exactly."

Raditz frowned deeply at his brother while Frieza perceptively narrowed his eyes at Goku and Raditz's quiet exchange. Raditz carefully, inconspicuously clicked off his scouter with a swift motion. "I brought you here so you could join us, Kakarot. You're either with us, or you're with Frieza. You can't just be on your own."

Raditz was whispering, hoping Frieza could not hear him in his close proximity to his brother. Raditz's fists remaining carefully raised as his brother's aggressive posturing never relented.

"Yes, I can." Goku replied with a determined scowl.

Raditz scoffed. His brother was truly a fool if he didn't realize by now the reality of his situation. And Raditz couldn't explain it all to him with Frieza there. At least it seemed that Kakarot realized Frieza was not his friend, but he seemed to perceive Raditz as a worse enemy, just because he wiped out one lousy race.

As Goku subtly widened his stance, digging his heels in the dirt to ready for a fight, Raditz realized he might never have the opportunity to tell Kakarot his true reason for recruiting his help. Even if they finished their fight without killing one another, they would not both be fortunate enough to walk away from the battle.

Frieza would see to it that someone died. His gleeful smile in the distance confirmed as much to Raditz. Facing off with his brother, Raditz finally realized that it was this exact moment that Frieza was preparing for when he separated the Saiyans. Kakarot was making the wrong choice. He had to know.

In one last, meager attempt at preserving his own life as well as what little was left of the Saiyan race, Raditz quietly pleaded to his brother. "Kakarot, I am your brother."

He met his brother's gaze at that sincere urging, relieved to see the other's gaze softening slightly at his plea. Goku's fists inched lower.

Raditz locked his gaze on Goku. "Frieza is a monster."

With a meaningful tilt of his head in Frieza's direction, Raditz rose his brows tellingly. Goku frowned deeply with a glance towards Frieza and nodded his understanding as those fists loosened and fell by his sides. "I know."

"This is exactly what he wants, Kakarot." Raditz said before lowering his own fists, once he recognized Goku's unlikeliness to attack in that instant. "We don't need to fight each other. You need to join your fellow Saiyans. We have a greater common enemy to contend with."

Raditz gave a satisfied smile at his brother's visibly softening resolve. Kakarot looked hesitant and unsure of himself to Raditz, which was all the hesitation Raditz would need to take the younger Saiyan by surprise if this conversation wasn't swaying him. Goku's guard was down. Raditz decided to watch his brother attentively to be sure he was keeping it that way.

"I'll never understand how you could do it." Goku said in a low, solemn tone of voice.

Raditz slightly cocked his head in surprise at the statement. He wasn't sure to what his brother was referring. It couldn't still be about Earth. Raditz assumed Kakarot was referring to purging in general, though Kakarot should have understood that already.

Raditz shrugged to himself when he realized his brother was saying no more. "To be honest, there is a thrill to it. Frieza's sent you on a few missions by now." Raditz said suggestively. "Don't tell me you didn't feel the bloodlust, the power surging through you, just as I do. We are warriors, Kakarot. Like I told you before, it is in our blood to enjoy killing."

Raditz raised his hands in a beckoning motion towards his brother, his eyes lighting excitedly at just the thought of his brother finally joining him and the other two Saiyans in battle, just as he thought would happen when he first went to Earth to find him. To his surprise, his brother didn't answer, simply frowned and stubbornly turned his gaze away.

"Kakarot?"

"…I can't."

Raditz sneered incredulously."You can't what?"

"I can't enjoy killing," Goku said as he turned his head, meeting his brother's gaze with a cold stare, "I can't understand how you enjoy it, and most of all, try as I might, I can't forgive what you've done."

A stunned moment of silence fell in the open, airy field. Frieza and Dodoria stoically watched the interaction with quiet interest while Goku glared calmly at the disbelieving face of his brother.

"I know how you can remedy one of those problems, Goku." Frieza chimed in with a smug smile.

The others all turned towards Frieza in surprise. Raditz bared his teeth in annoyance at the tyrant and hurriedly clicked his scouter back on. Hearing Frieza call his brother by that Earth name cemented the reality of how close the two of them had been over the past months. Raditz knew that whatever Frieza was going to suggest was going to be a problem.

"I've only been hearing repeatedly for months about your discontent with your brother's betrayal." Frieza continued arrogantly once he had everyone's attention. "I'm sure if you kill him, you'll begin to understand the joy of a satisfying kill."

While Dodoria quietly chuckled by his side, Frieza smiled sadistically at his own suggestion. Goku stood in place, his head lowered in thought as Raditz debated his next move. He considered moving in to attack. Kakarot's guard was still down, and when Raditz's scouter registered the surrounding power levels upon switching on again, it still reading 2300 for Kakarot. If Kakarot decided to listen to Frieza, Raditz had to be ready. He assumed a fighting stance again, knowing the chances were good that Kakarot would attack after everything he and Frieza both had just said.

Goku raised his gaze with a deep frown and a look of determination, and Raditz sneered defiantly at him. He was certain his brother had just made his decision, and Raditz would be damned if he allowed his brother to take him out with Frieza and Dodoria witnessing the kill.

With a ferocious battle cry, Raditz launched himself at his brother, attempting to use the element of surprise to land his first hit before his brother would have the chance to counter his attack. All at once, his scouter beeped wildly with a power fluctuation as his wide-eyed, off-guard brother seemed to disappear while Raditz propelled himself through empty air. Raditz's eyes widened in astonishment at the clear miss before he tucked his legs and flipped several times to slow down his hasty progress from the battlefield and land on his feet.

Raditz jumped into a stance as he spun to face the direction from which he'd just come, searching the area for any sign of his brother. Frieza cackled on the sidelines, but Raditz paid no attention to him or Dodoria. The scouter finally alerted Raditz to the presence in the air right on top of him. He looked up to see the bottom of his brother's boots floating over him, hovering there mockingly. Raditz growled angrily at the display.

Goku floated to the ground in front of Raditz, a bemused frown on his face as Raditz's brows lowered into a deeper glare. Raditz was shocked that Kakarot was able to move that fast. He didn't want to believe that Frieza had actually trained Kakarot. Raditz clenched his fists tightly by his sides as he debated his next move.

"I thought we were talking, Raditz." Goku said with a calm, confident gaze and a surprised tone of voice.

Raditz's fists tightened even more at the sight of his brother's relaxed countenance. He should have been on edge, knowing that Raditz was trying to hurt him. "Frieza decided we were done talking." Raditz replied abruptly.

It was true that Raditz decided as much as well, but if he hadn't, he knew Frieza intended to drive them into a fight eventually. It was inevitably going to happen. Raditz just made the first move.

"Come now, Raditz." Frieza replied playfully. "You know as well as I do that I decided no such thing. You're the one who decided to attack your brother, just like you attacked his friends and family."

Goku narrowed his eyes at Raditz upon hearing that painful reminder. Dodoria smiled back at Frieza, finding amusement with the interaction. Frieza smirked at Dodoria knowingly, "If my brother demonstrated that pattern of betrayal, I'd certainly want to kill him."

"Raditz!" Goku yelled, glaring at his brother as he tensed his body and lowered himself into a ready crouch.

Raditz turned to face Goku in alarm. There was no more dissuading Kakarot after Frieza so inconveniently riled him up by mentioning the deaths on Earth again. Raditz readied himself as well, growling irately in frustration. If Kakarot wanted a fight, Raditz wouldn't be the one to hold back. Raditz lunged at Goku again, reaching his brother and smirking with satisfaction as he pulled his fist back and drove it forward for a right hook towards Kakarot's face, but he only sliced through air before Kakarot's image faded away. Raditz balked loudly, taken aback by Goku's escape from his second attack as he frantically searched his surroundings, turning side to side with wide eyes.

"Over here." Goku said in a smug tone from just behind Raditz as Raditz stiffened in shock at the proximity of the voice.

Before Raditz could turn and react, a gripping pain seized him, bringing him to his knees with a cry of agony. "Kakarot, let go of my tail!" Raditz yelled irately with a sneer over his shoulder towards his brother's calmly glaring expression behind him.

"This hurts, doesn't it?" Goku asked knowingly as he squeezed the sensitive appendage harder, causing Raditz to pound his fists on the ground as he laid himself forward in an attempt at escaping the pain. "But it's nothing compared to the pain you've inflicted on so many people."

Raditz clenched his eyes shut tightly, prepared for more pain as he was left vulnerable on the ground, when to his surprise, the pain subsided. He glanced hesitantly over his shoulder to see his brother standing over him, having willingly released his tail.

"Kakarot…" Raditz began pleading with a glowering gaze as he rose to his feet, wrapping his tail securely around his waist.

He couldn't continue with what he wanted to say, though. By the look in his brother's eyes, there was nothing he could say to defend himself. There was no getting through to that idiot who was unknowingly eating right into Frieza's hand.

Raditz growled furiously, startling Goku with his sudden change in demeanor. "Your beloved Earthlings were weak, Kakarot! They didn't deserve to live if they couldn't defend themselves."

"Everyone deserves to live, Raditz."

"Not everyone." Raditz muttered defiantly.

Goku bared his teeth angrily and disappeared from Raditz's sight, startling his brother as he was suddenly right in front of him, standing face to face with an imposing glare.

Raditz leaned away from his brother's intimidating glare, his eyes bulging in terror and shock, before taking a shaky step backwards. "Frieza did train you. You're much faster than before."

His brother's speed wouldn't have been the only thing that improved under Frieza's training, and Raditz didn't want to die. He was determined to be the one escaping this fight with his life.

Raditz regained his courage through that determination as he steadied his footing for another attack. "But I'm still going to beat you!"

Raditz decided to feint a punch before he abruptly jumped. He flipped over his brother's head to land behind him and strike with a forceful jab aimed at his brother's back. Goku glanced at Raditz behind him with a confident smirk as the strike came, but never landed, as Goku once again evaded Raditz's attack in an unseen movement. Raditz looked around again at the disappearance of his brother, becoming extremely frustrated with the way Kakarot was toying with him. Kakarot should have just stayed in place and fought. He didn't know why his brother wasn't fighting back, but Raditz couldn't touch him and it was unsettling. If Kakarot didn't want to trade blows, Raditz would have to draw him out to do so.

"Little brother!" Raditz called mockingly into the open field, still unaware of his brother's whereabouts. "At least your pathetic bald friend and the old man on that little island attempted to hit me! Even your crybaby of a son had the guts to strike me and land a punch! You can't even do that, it seems!"

Raditz readied himself for the attack he knew was due to come now. But he was not at all prepared for the massive surge of pain that traveled through his abdomen as his brother's fist compressed his organs into his ribcage with such overwhelming power that could not have come from a power level of 2300. Blood spewed from his mouth as his eyes bulged at the sight of his glaring brother in front of him, who had not been there a second ago.

"That's for Krillin." Goku sneered as Raditz coughed and stumbled forward while the fist in his gut retreated and his brother seemed to disappear again. "This is for Master Roshi!"

Raditz sneered angrily, but was too busy recovering from that first blow to counter what was coming. A foot smashed into his back, damaging his ribs and forcing him flying through the air until he collided with the first rocky protrusion in his path. Raditz collapsed with his eyes closed in the rubble of the broken rocks before the erratic beeping of his scouter alerted him to stand and fight through his pain.

Just as Raditz scrambled to his feet, Goku was on him again, striking him in the cheek with a powerful punch that forced the spit flying from his mouth and his entire body careening to the side. Raditz landed on the rocky ground with a tumultuous crash. He groaned in pain, unable to move after that most recent hit. Frieza and Dodoria floated closer to the relocated battle scene, following the fighting brothers as they continued observing the fight with impassive frowns.

"And that was for Gohan." Goku added as he calmed and his mood turned somber upon watching his bloodied brother slowly struggle to his feet with a pained grunt.

Frieza let out a low laugh at the sight of Raditz's suffering and Goku's vindictive attacks, though the tyrant was surprised that Goku wasn't going all out. If it was Frieza, he would have continued torturing the weaker man, but his pupil seemed to be letting up.

"Why don't you finish him already?" Dodoria impatiently asked Goku, drawing a surprised glance from the Saiyan.

Frieza frowned in discontent. He rather enjoyed a slow, painful death. He didn't want to see Goku finish his brother off just yet.

To Frieza's pleasant surprise, Goku shook his head at Dodoria in disagreement. "I don't need to finish him. He knows now that he doesn't stand a chance." Goku responded cockily.

Raditz growled furiously at the suggestion. Raditz realized that his brother was overpowering him, but he couldn't possibly be suggesting that Raditz would bow down that easily.

"What?!" Frieza yelled in disappointment to Goku's remark. "Of course you are going to finish him."

Goku ignored Frieza's threatening glare. "This isn't even a challenge." Goku complained with a tone of deep disappointment.

Raditz yelled furiously at that comment. Any Saiyan would be offended by being so easily dismissed in battle. Maybe his brother had grown stronger, to the point that Raditz couldn't match his strength, but Raditz still had a trump card. Raditz laughed, almost maniacally, as a last resort occurred to him. The others all looked at him with deeply perplexed expressions. Goku crossed his arms and raised a brow with concern at his beaten brother.

"You should know better than to think a Saiyan would walk away from a fight defeated, Kakarot." Raditz said as his laughter subsided. "Maybe you have me beaten in this form. But there's something you haven't accounted for. Unlike you, I still have my tail, the source of our true power!"

Goku frowned in confusion as Frieza and Dodoria narrowed their eyes suspiciously and Raditz laughed haughtily again, "The moon isn't out now, but we Saiyans don't need the moon to complete our transformation."

"What transformation?" Goku asked, taken aback by Raditz's suggestion as Frieza and Dodoria gaped in realization of Raditz's plan, as well as surprise at Goku's lack of understanding.

"Moonlight is a natural source of blutz wave power," Raditz said, "but we Saiyans can artificially create the waves, as the three of us true Saiyans often do to purge planets without a moon. By channeling our own energy from within ourselves and combining it with the planet's atmosphere, we can make an artificial moon, complete with blutz waves anytime and anywhere we want!"

Raditz laughed as he raised his shaky hand beside his face, his palm upturned as a glowing orb formed in his hand. Goku watched the glowing ball warily as he felt Raditz's ki lower and he attempted to understand what Raditz intended to accomplish with that.

"So their tails are the key to the transformation." Frieza muttered pensively to Dodoria, whose eyes remained fixed on the pair facing off as he nodded numbly in agreement. "If that's true, Goku can't transform into the giant ape. We won't have to worry about his power multiplying from where he stands." Frieza mused with quiet relief. Then he smirked to himself. "Perfect."

"As soon as I release this into the sky," Raditz said as he raised the glowing orb and narrowed his eyes at his brother, "the transformation will begin and there's nothing you can do about it. Bear witness to the ultimate power of the Saiyans-the giant ape, destroyer of planets!"

Goku yelled in startled awe as Raditz threw the orb forcefully into the sky with a shout of effort. All eyes followed the traveling orb until it sparked in the atmosphere, creating the illusion of a real moon. While Goku's eyes trembled at the shocking sight and concern over Raditz's suggestion of a transformation, Raditz's eyes fixed on the artificial moon as he smiled evilly. Frieza and Dodoria waited, knowing what to expect, though they could not do anything but watch at that point. Raditz's eyes began to widen, his pupils going white as he laughed victoriously and his muscles began to rapidly expand and contract.

Goku fixed his gaze on Raditz, gaping in awe as his brother gradually transformed, his teeth elongating into fangs, his body growing and sprouting fur, his eyes turning red, before he enlarged to massive proportions and Goku had to jump back a distance just to see his brother's face any longer. Of course, Goku was having trouble wrapping his head around the fact that the giant ape face he was now looking up at was Raditz's. Raditz stomped his feet and growled, his tail swaying behind him before he punched his massive fist into a nearby rocky cliff, demolishing the entire formation with that powerful blow.

As Raditz released a monstrous growl, Goku slowly shook his head as his brows knitted with perplexity and his gaze pensively lowered to the ground. The full moon. The tail. The transformation. "The giant ape monster." Goku mused to himself quietly in realization.

It was the giant ape monster from Grandpa Gohan's warnings all those years ago, the one that came out on nights of the full moon. If all Saiyans with tails underwent that transformation during the full moon, then it was him all those times before. Goku was the monster all along, the one that destroyed the tournament arena...and killed his grandpa. Goku was so taken aback by his upsetting revelation that he didn't notice the giant foot Raditz had raised, which was lowering to crash down on top of him.

"Look out, you fool!" Dodoria yelled in warning to Goku, his eyes bulging in alarm as Raditz's foot crashed down on Goku, slamming loudly with an earth-trembling impact. Raditz raised his fur-covered, clenched fists in the air victoriously as he roared and stood alone in the wasteland with only Frieza and Dodoria remaining to watch him on the sidelines. Dodoria grit his teeth with frustration, shaking his head in disbelief at what he'd just witnessed. "Lord Frieza…all that time you spent training that useless idiot-"

"Relax, Dodoria." Frieza interrupted his frazzled henchman with a smile and a cool, confident gaze towards the wildly flailing, bellowing giant ape before them. "I haven't wasted my time."
