"Alright, I was kind of expecting to bump heads with a crazy-strong guy like this. Let's see what it can do!" Goku released all his Super Saiyan aura to burst outward with a radiant shimmer, powering up greatly before letting his body absorb all the outgoing aura within and snuffing it out to preserve stamina and Ki as much as possible.
Rushing toward Hatchiyack, Goku bumped against a translucent emerald shockwave that flinched him up. The moment he opened his eyes back up, the towering machine of resentment was up in his face, driving a strong right straight into Goku's face before sweeping the leg and laying Goku out flat. Just as Hatchiyack's many gems lit up with an emerald glint, Vegeta rushed past Goku, enveloped in a golden shine.
"Out of my way, Kakarot!" he barked out to the fallen Saiyan, who rubbed the back of his head while getting up.
Vegeta's dashing left crashed into Hatchiyack's cheek, though barely moved the machine of vengeance. Eager to try again, then again, as many times as it would take for him to succeed, Vegeta wound back and drove an explosive elbow strike to the core of Hatchiyack's body, making the artificial titan stumble. Channeling as much Ki as he could during his opening, Vegeta slammed his fist into the central gem of Hatchiyack's body, letting it all out in a point-blank energy blast that detonated at the point of Vegeta's right uppercut. The result was a booming pillar of energy indenting Hatchiyack's core and reforming behind him into a vivid blaze that blew Hatchiyack into the air.
Vegeta chased after his target but a glint of emerald light glistened in Hatchiyack's eye, forming a fading emerald shockwave around him that bounced Vegeta back off the rampaging calamity. With a sharp snap, Super Saiyan Gohan appeared before airborne Hatchiyack, punching him in the body a few times before lashing with a jumping high kick to the beast's chin, then switching to a flying thrust kick. The entire combination seemed utterly ineffective against the monstrous machine, but Gohan wasn't one to quit easily. Bellowing from the bottom of his chest, he released his golden Super Saiyan aura from his body and unleashed a combo of wild punches and kicks, all of which Hatchiyack stonewalled with a grumpy expression.
Just as Gohan raised his arms over the head to finish his ineffective combination with a double ax handle slam, Hatchiyack may have sensed danger, as he simply scooped Gohan up and lifted him over the head before flinging him down into the floor of the inner core. Gohan cried out in pain as he slammed with sufficient force to dislodge metal debris and smash surrounding supercomputers and servers to pieces with his crash landing.
The largest core gem positioned atop Hatchiyack's oval-shaped head lit up with an intense emerald glow, burst outward with a lime energy wave. Goku and Vegeta vanished out of its way, narrowly avoiding having to deal with it as the wave blasted out of the inner core room and colored the outer facilities with devastating fields of emerald light while sending the entire Dark Planet Star into a severe series of quakes.
"Alright, how 'bout this?" Goku pulled his knees up to the chest and positioned his arms by his sides, bundling together before a blitzing charge toward his opponent. The entire body of the Super Saiyan stopped, transferring the force of inertia through his left arm alongside his own strength to deliver a skillful one-inch jab that packed tremendous force vastly surpassing the best of Goku's power punches. As the ripping resonance of sheer force spread throughout Hatchiyack's body, causing havoc, Goku kept going with an uppercut to the gut and a resounding roundhouse that sent the goliath flying.
Chasing after the flying machine of revenge, Goku positioned himself over the horizontally soaring monster and delivered a flurry of fists before letting out a vociferous battle cry and slamming Hatchiyack down into the ground with an overhead double ax handle slam.
As smoke from the crash began clearing out, the stumbling figure of a sneering Hatchiyack appeared from the clouds of dust. Without waiting for special permission to attack, Vegeta appeared before the scornful juggernaut and smacked his push kick into Hatchiyack's chest. While the powerful kick didn't quite achieve its goal of sending Hatchiyack flying or skidding aside, it seemed to stun the goliath and force him into a stumble.
Using his arms as hooks, Vegeta tripped the giant up before kicking off the ground with a free-flowing kick that truly sent Hatchiyack packing into the air. Feeling the flow and high on his own success, Vegeta continued the combination of kicks, turning round and round and delivering a successful blitz of roundhouses while targeting different angles or body parts until Vegeta's Super Saiyan aura exploded around him and he finished the combination with an explosive roundhouse and positioned his arms over his head.
"I'll scrap you like the rest of the useless junk here!" Vegeta declared, channeling a large, yellow energy bomb over his head that he then hooped at Hatchiyack and detonated in a golden, destructive dome. Panting, Vegeta dragged his glove across his lip to wipe the slobber and dirt off of it before casting a sullen glare at Dr. Lychee. "Your Tsufurian vengeance is as toothless as your extinct race! Evolutionary dead-ends belong in the trash of history!"
Dr. Lychee did not humor that with a response, simply hovering above the ground with his legs crossed. Despite the calm reaction, the fact that the mad scientist looked so serene about his alleged ultimate weapon taking a whole bunch of damage at once made all three Super Saiyans keep up their guard.
"SAIYANS… REVENGE!" a pitiful combined cacophony of wailing voices all streamed together into a booming symphony as Hatchiyack erupted into a blaze of emerald aura that ripped through the golden energy dome enveloping him and swatted away the dust and debris lingering in the surrounding air.
"Watch out!" Gohan butt in front of Vegeta with his arms pushed to the side, expelling a lively bubble of golden energy around him that worked as a shield. In a blink, the stationary and scowling Hatchiyack rippled away like an ethereal afterimage with another, solid and very real doppelgänger, smashing into the walls of Gohan's shield like a battering ram and shattering it. While the devastating aftereffect sent both Gohan and Vegeta flying away like bowling pins, the crash also stopped Hatchiyack's charge after its afterimage trick.
"Nice instincts, Gohan, saw right through that!" Goku snickered with a thumb up for his son while Vegeta crossed his arms and turned his look away.
"Despite your fighting spirit, you have a 0% chance of victory against Hatchiyack," Dr. Lychee explained, hovering around his supreme creation like its moon, satelliting a giant planet. "Hatchiyack feeds off hatred and violence and becomes stronger from it. Unfortunately for you, hatred and violence are all that Saiyans are good for. Even with just its base intelligence, Hatchiyack is an unmatched predator to your species."
"So, you've spent your centuries rotting here, feeling all miserable about your poor race, and built this hunk of junk to have your revenge on us? Is that about it?" Vegeta turned his look back at the battle at hand and focused his hateful glare on Hatchiyack and Dr. Lychee. "If you think that entitles you to anything else than execution at my hands, you're delusional! This revenge machine of yours is a threat to the Saiyan race as the King of Saiyans, I'll put it down here and now. You should feel lucky, I'll keep you alive and finish you off last just in case we still need you to fly this oversized junkyard back home."
"Such a primitive race. Yet, I think your greatest weakness is that limited intelligence of yours, not your ruthlessness. It blinds you and lets your arrogance take over once you see one angle of the complete picture, refusing to see the rest. It is as you said before though, species reaching an evolutionary dead-end do belong as dust covering the tomes of history. Tsufurians refused to evolve as I have, thus they went extinct at your hands. Now, I'm afraid, it's the Saiyans' time," Dr. Lychee said with a bitter expression on his face, visibly disgusted by the golden splendor and vigor of the Super Saiyans that have reached his laboratory in the inner core of the Dark Planet Star.
"Hey, are you done talking yet?" Goku's face shriveled in frustration. "Sorry, but I kind of want to fight that big giant you've built, and all of your yappin' just kind of makes me more anxious for the fighting to start…"
"So anxious are the dinosaurs to greet the asteroid…" Dr. Lychee closed his eyes and hovered away from Hatchiyack.
"SAIYANS… FAULT… DIE… SAIYANS…!" faceless bawls and screams joined to a terrible harmony that comprised Hatchiyack's staticky voice. The vengeful juggernaut leaned down before taking off to collide with the three Super Saiyans together.
"Nice, thank you, Dr. Ritchie!" Goku snickered to himself, taking off to answer Hatchiyack's call for brutality with passionate excitement. An emerald energy field enveloped Hatchiyack while the three Super Saiyans lit their auras up as well, powering up to the limit. The four novae of pure energy danced across the entire inner core laboratory, colliding with devastating shockwaves, causing sizzling discharges of energy and typhoons infused with Ki. The cascading shockwaves bent the entire inner core facility out, with one lump shooting out after the other. More and more skyscraper-sized supercomputers and lab equipment blew up and collapsed all around the core interior while the boiling-blooded bout was just heating up.
The uncontrollable collision stopped with Goku's elbow embedded into Hatchiyack's waist while the colossus gasped in torment, with wide and terrified eyes. Slipping underneath Hatchiyack's attempt to wrap his arms around him, Goku swept the giant's legs before knocking him away with an aerial thrust kick. Spinning around, Goku delivered a devastating combination of roundhouses that positioned Hatchiyack high in the air. The mighty Super Saiyan drew his arms back, cupping them by his side as all of his lustrous Ki exploded with such radiance that it drowned everything else within a visible distance in the shadow of the golden light.
"Super Kamehameha!" Goku yelled out, channeling his signature move quickly while his opponent was still in the air and stunned. With a resounding roar, the raging Super Saiyan thrust his arms out and fired the Super Kamehameha point-blank, enveloping Hatchiyack in the tunneling destructive energy wave as chips of its pink armor flew off in all directions.
A look of shock twisted Goku's face when the parallel clouds of smoke parted slightly to reveal Hatchiyack with its arms crossed, having tanked the entirety of his strident blast with minimal injuries. Only a handful of dirty spots and grazes decorated the wrathful colossus as if it had used the infinite grief and righteous fury of the Tsufurians powering it to recover from a troublesome situation and withstand any blow.
"What are you doing!?" Vegeta barked out, kicking Super Saiyan Goku away from the side with a flying knee before taking a fighting stance and lashing out at Hatchiyack before the dust from the Super Kamehameha fully settled. Enveloped in a lustrous aura of golden Ki, Vegeta slammed his elbow into the giant's general location but only found Hatchiyack's armored forehead slamming right back at him as Hatchiyack head-butted the elbow strike and forced them into a power struggle.
Never being one to back off from a challenge, Vegeta extended his hands and locked them up with Hatchiyack but, judging from the occasional twitching that left the power struggle to move back in Vegeta's direction every time, the Saiyan royalty was going to lose this struggle. Shooting a knee strike to the chin of the goliath didn't help either, as it only aggravated Hatchiyack into exploding with all of his force at once. Seeking to avoid getting overpowered, Vegeta rolled back in mid-air and allowed Hatchiyack to push uncontended, entering a vertical grappling roll with his enemy.
Shining with their respective auras, Super Vegeta and Hatchiyack exchanged blows though where Vegeta put the effort in defending from his opponent by reflecting or guiding Hatchiyack's blows away, the rampaging machine of vengeance let it all out in its offense, shrugging off Vegeta's returned favors which only frightened the King of Saiyans deep in his heart more and more. Vegeta's body demanded that he fled from a close-distance engagement with this reckless monster immediately. He didn't seem to feel any pain or fear for its life and was fully ready to sacrifice everything just to gouge, punch, kick, blast, and mutilate just one more pound of Vegeta's flesh. Calming his breathing and drawing his aura back into his body, Vegeta canceled his offensive beatdown entirely, focusing merely on avoiding his opponent's blows.
There they were. The openings were plentiful and, in his calmed state of mind, Vegeta slipped stiff kicks and jabs into each one of them, making a mockery of his brutish opponent before rolling over Hatchiyack with an overhead kick. The Saiyan royalty gasped in shock when Hatchiyack's head merely twitched to the side and the bio-engineered avenger glared at Vegeta with a sullen look that made the Super Saiyan vanish in a combination of swift and blurry afterimages to mask his retreat.
"Just… What kind of monster is this?" Vegeta cursed with sweat pouring down his face as he threatened to chip his gritting teeth from the wrathful grind.
"SAIYANS… MAKE PAY…!" Hatchiyack howled, blinking in a field of static emerald energy as the monster flexed its muscles and crossed its arms out in front of it.
"Wh… Who turned off the lights?" Goku looked around in awe as everything except for their radiant Super Saiyan auras turned black and sank into the shade. Bolts of green light surged into the gems on Hatchiyack's crossed-up gauntlets and its face.
"Why isn't it getting any weaker from the damage we've inflicted? It only seems to grow stronger!" Vegeta clenched his fists and looked down, realizing that this battle might push him into the straining royal transformation of Super Saiyan 2, despite the battle going rather well until now.
"It's… Not moving?" Gohan muttered, turning to Hatchiyack who seemed to have gotten frozen in place with more and more energy flowing from the outside into his shimmering gems. "Why is it powering up in the open like this?"
"Damn…!" Goku gritted his teeth. "Can't gauge this evil Ki at all. It's just like with those Destron monsters earlier. But if it thinks it can just flex on us with a technique this slow, it's got another thing going! Ka… Me…!"
Seeing his father beginning to channel a Super Kamehameha, Gohan put his hands out in front of him and drew them back to his side as well. "Ka… Me…!" he chanted out.
"Tsk… It doesn't matter how powerful you are!" Vegeta barked out, flashing with rapid surges of light as his Super Saiyan aura grew twice in size and luminosity and a white electric surge flowed through his body, spiking his hair further. Having adopted his regal Super Saiyan 2 form, Vegeta thrust his arm out and began accumulating blue sparks of energy around his hand. Electricity sparked and crackled in an electrified field of energy that bound the flowing Ki together into a cerulean energy bomb at the palm of Vegeta's hand. "Big Bang Attack!"
"Haaaa!" Goku yelled out, thrusting his arms out and releasing an indomitable tunnel of energy that flowed through his entire body. A Super Kamehameha so massive and intense that it couldn't be contained in an energy wave around the Super Saiyan's hands but formed from all around his entire body. It was more than just an energy wave, but a whole spreading field of azure energy.
"Haaaa!" Gohan joined his father's attack with an identical release of energy. Vegeta's Big Bang Attack slammed straight into Hatchiyack, drilling into the face and chest of the cross-armed colossus and throwing sparks everywhere from the resulting struggle. Despite Vegeta's power-up and use of his Big Bang Attack, the blast didn't detonate upon impact but continued to push and struggle against Hatchiyack's sheer hardiness. That was until the two tunneling fields of azure energy slammed into the other end of the Big Bang Attack and caused an expansive blue nova explosion.
"You were one wild guy, but you left yourself way too open…" Goku snickered while clutching with his right arm to shield himself from their own combined might blowing up in their faces and threatening to devastate this entire space station despite all of them focusing their Ki on merely devastating their opponent without threatening the galaxy it resided in.
"Wh… What is this!?" Vegeta gasped, with eyes wide open and staring into the blazing blue nova that settled into a city-sized orb, growled and sizzled with energy, sending rampant quaking shockwaves that bent and disassembled the inner core chamber at its limits but it still didn't explode. Just like before, just like with his Big Bang Attack, the resulting blue nova from their combined attack remained frozen at a certain stage of development and didn't show any signs of progressing onto the next one.
Then, the combined attack began drawing smaller and smaller still, like a ball of ice cream that was put in front of a fire and was rapidly melting away into a puddle. A puddle that then flushed into a singularity of emerald energy and vanished without a trace. One absolute, immovable thing remained. Hatchiyack with its arms crossed, still powering up its ace move.
"REVENGE… SAIYANS… DIE!" the millions of Tsufurian voices howling and wailing through Hatchiyack spoke in thunderous unison as Hatchiyack put its arms out in front, unleashing a vicious green energy blast with a blinding flash of light at the center and an expansive field of emerald energy that drowned the whole inner core laboratory chamber.
Gohan's tormented scream echoed in the ears of the cowering Saiyans that couldn't do much of anything but brace themselves in the blinding dominance of the Revenger Cannon that had gobbled up the whole room. The devastating energy wave blew the teenage Super Saiyan away while the overwhelming area of effect around it kept the other Saiyans struggling against the overflowing calamity of Hatchiyack's channeled power. When the apocalyptic light vanished away, Goku and Vegeta still struggled to open their eyes for a few seconds and their vision blurred even when they pushed through the searing migraines that resulted from opening their eyes.
Gohan was nowhere to be seen, just a handful of his violet cloth shreds flowed through the air in a controlled fall. Goku's eyes widened in shock and his mouth dropped. Any trace of sense disappeared and Goku's trembling stare became blank as if it was him who got blasted away by the full channeled might of Hatchiyack's power.
"Do you feel it now, Saiyan? The despair, the meaningless of death… Even if Hatchiyack while it is without a host cannot think clearly and acts as a mindless monster, and it likely targeted the boy first because it was your son that inflicted the most actual damage to it earlier, I must say that I agree with its primitive choice for a target," Dr. Lychee stroked his beard while in mid-hover. A crimson protective energy bubble retreated from warding the Tsufurian cyborg from the terrifying destructive effects of his ultimate weapon while the laboratory still failed to settle down from pernicious earthquakes.
"Don't lose your head, Kakarot, use your Ki sense, for Pete's sake! Your son's Ki is weak, but it's still there!" Vegeta tried stopping Goku from losing his cool head and further aggravating their chances to defeat this Tsufurian abomination but Goku's eyes had been sunken under his hair and covered in the dancing shadows of the flames gathering across the laboratory chambers because of failing or destroyed supercomputers all around.
"You monster…!" Goku snarled. "What did you… Say!?"
"Oh… You seem to care about what I have to say now, Saiyan. That's right, I agree your son should die first and let you experience firsthand the pointlessness of oblivion's embrace as Tsufurians experienced it at your hands. I've come to understand your species over the centuries of upgrading myself, studying, building up, and preparing the Four-Stars Plan. You don't fear death in battle, you embrace it, so merely maiming and killing you would just play into your daydreams. You need to understand, you need to feel the emptiness, the hopelessness, the void, to truly break," Dr. Lychee continued to pontificate.
Goku's Super Saiyan Ki erupted into a wild, free flow around his body. Vegeta turned around in confusion as trails of Destron began surging toward the wrathful Saiyan and merging with Goku's aura, forming a pitch-black outline. The corrupting influence of Goku's wild wrath combined with the jets of ever-present Destron Gas darkened the hue of Goku's aura, turning it fiery orange as the black outline delved deeper into Goku's radiant aura and surrounded his body as well. When Goku turned his eyes up, his spiky golden hair had been going wild in rustling while his pupils had utterly vanished without a trace.
Goku let out a barbaric roar that sent the rampant quakes into overdrive and threatened to crumble the dimensional walls into a pitch-black void from which there was no return. The Saiyan's twisted, scorned expression followed a drastic bulk-up of the Saiyans muscles. As the resounding rage flew throughout Goku's body, bolstering his physical force to unforeseen heights, the berserk Super Saiyan blinked away with a tremorous clamor.
Another thunderous slam sent rippling bubbles that tested the dimensional fabric of the Dark Planet's interior as Hatchiyack moved in an instant, surpassing Goku's own blinking speed and placing itself in the way of the lashing out Saiyan berserker and Dr. Lychee with a human shield. The Super Saiyan's ripping punch met Hatchiyack's cross-shaped block and sent rippling shockwaves throughout the surrounding, fiddling with time and the sense of all other dimensions but Hatchiyack stood firm and just stared with a cold dead look at the equally despaired father lashing out at an unjust world that tried to take his family away from him.
