Goku's sight lingered on a horde of soldiers surrounding and unleashing barrages of plasma blasts at Gohan. The child grunted in pain and covered up to try and resist and the relentless offensive of the far weaker soldiers who used clever military tactics in order to keep the hybrid Saiyan and his mother at bay as letting them get close meant complete obliteration for their invading force. Little Gohan let out an angered roar and shielded himself with a Kiai bubble, deflecting the following blasts and rushing off in chase for a better position to fend the enemy off from.
"Stop!" Goku cried out, extending his hand to Lord Slug who only displayed a wicked, toothless smile, enjoying the torment of the durable little brat. "Why are you doing all this?"
"I'm looking for a Saiyan woman and your Dragon Balls. Though that is not why I enjoy seeing your child crying out in pain. That is merely why I've hand-picked your puny planet for conquest. The reason why I relish in seeing Earthlings exterminated like flies by my Evil Clan is that I am pure evil!" Lord Slug extended his hands out, bolstering his confidence and infuriating Goku for when the Saiyan looked back at him, it was no longer with eyes full of dread and worry for his family's well-being. It was a look of righteous anger and need to punish the withering Namekian tyrant.
"I said stop this!" Goku roared as he dashed the entire distance between him and Lord Slug in a blink, throwing a right-handed cross right in the center of Lord Slug's cross-shaped block. While the Namekian invader looked overjoyed to have driven the Saiyan mad, when he truly felt the overflowing force behind Goku's blow, his face turned dire and he let out a grunt upon skidding back on the ruined city street for multiple blocks.
"What unruly power. I might not get it done without the power of my youth…" the evil Namekian grumbled to himself, reaching for the earpiece on his hi-tech helmet. "Gyoshu, are the vessels ready? I might need to assimilate promptly."
Cybernetic babble filled the air, the answer didn't seem to please the Namekian for he lowered his blocking arms and yelled out in frustration. With Goku's resolute voice filling the cold, ghastly void of the emptied and frozen city, Lord Slug leaped into the fray to answer the bloodthirsty Saiyan's call for battle. Slug had Goku beat in terms of size though that fact didn't seem to bother Goku whatsoever. The martial artist danced around Lord Slug's hefty blows and jabbed and kicked wherever he could find and opening though Lord Slug's Namekian body manipulation allowed him to bend and stretch his limbs to block or deflect the Saiyan's strikes in ways that Goku couldn't read right.
"Take this!" Goku cried out, leaving Lord Slug to deal with an afterimage as the Saiyan appeared over the elderly space conqueror with an overhead kick meant to crush Slug into the ground. Using just his left, Slug blocked the strike and pushed Goku to roll further in mid-air.
"Your strength is impressive, Saiyan. I haven't met anyone this strong. Against my aged body you might just stand a chance," Lord Slug admitted while stretching and warming up in between clashes with the pissed off Saiyan.
Goku's sights were in-between this clash and his family. Gohan was cleverer than Goku gave him credit for and it didn't appear as if though he needed much help. The little one had led the chasing parties of Lord Slug's grunts into an alleyway where he blasted them away with one, mighty Ki wave. Chi-Chi, meanwhile, struggled against a concentrated beam of plasma emitted from one of Lord Slug's giant battle-bots that towered even over the South City skyscrapers.
"Hold on, Chi-Chi, Gohan, it doesn't look like this is a fight I can settle quickly. Not unless I use that…" Goku muttered, fixing his glare back on Lord Slug as he placed his arms by his side and straightened his back. "King Kai's Fist!" he yelled out. An intense, red aura enveloped Goku, rustling his hair and clothes and dyeing his skin in the shade of a subtle swelling as his muscles tensed up and the Saiyan prepared to use all of his strength to deal with Lord Slug as quickly as possible, even though he felt confident about his odds of winning even without his hidden ace.
"What is that energy!?" Lord Slug's eyes widened in shock though his proclamation of respectful fear was soon shut down when Goku thrust his palm, sending Slug flying with a combination of pressurized air from the speed of his palm strike as well as a Kiai burst from his hand. Before Slug could recover, Goku was already pursuing him still burning up with the scarlet flame and his right fist wound up and looking to crash and break his opponent as soon as possible.
The collision between Goku's rushing downward strike sent Lord Slug bouncing off the ground and into the air. The infuriated Saiyan thrust his palm up, adding an additional Kiai burst to send his opponent flying even higher and in a more controlled ascent. The Saiyan vanished and appeared in front of his airborne opponent with a skyward kick that tested the integrity of Lord Slug's chin as the conqueror's head extended to an unruly extent from it.
Blazing and desperate to finish the battle as soon as possible, Goku raced around his soaring opponent and drove his fists into the back of Lord Slug, countering his rising with a downward force of greater strength and stressing the Namekian's spine. The evil Namekian roared out in pain, spitting up slobber and purple blood though, despite Lord Slug's exclamation of pain, Goku kept on rushing down, carrying and crashing his opponent and dragging his face and limp body across the street, ravaging it and shattering windows where he dragged Lord Slug.
Slug grunted and spat up bodily fluids in his troubled rise to his knees. His helmet carried decent signs of battle damage as cracks littered its surface while his baggy space suit tore open where the wear and tear and battle touched the intergalactic criminal. Goku didn't look too pleased either, it was self-evident that he had hoped to settle this bout with this one amped up assault but while the Saiyan had a confident edge on his downright ancient opponent, Lord Slug still had ample power not to be done in too easily and his Namekian physiology allowed him to survive harsher punishments that would have broken any mere Earthling that found themselves on Goku's warpath.
"Impressive, downright amazing!" Lord Slug commended Goku's power as he rose to his feet. "Though it seems that your otherworldly might has dwindled down somewhat. Lower even than it was before?"
"It doesn't matter, I'll just have to take it even higher!" Goku proclaimed with a spiteful response to his opponent.
"Oh, you must… After all, who knows what my soldiers are doing with your wife and child right this moment. Go ahead, Saiyan, roar, explode with all of your power!" Lord Slug taunted Goku and the Earth-raised Saiyan martial artist didn't respond well to being taunted that way. The evil Namekian had sensed an opportunity to fight in a nefarious way and manage to come out on top against this unexpectedly towering hurdle placed before him. What the Saiyan had in rock-hard muscle, he lacked in brainpower, it seemed, or, at least, his sentimental attachments to good and justice made him abandon fighting smart.
"This is the full-power of King Kai's Fist!" Goku clenched his fists, putting them out as a warning to his opponent. "King Kai Fist X 2!" The signature red, exploding aura of the King Kai's Fist technique enveloped Goku as the intense physical strain drove the Saiyan to hunch over and spread out his balance as wide as possible in order to withstand its adverse effects. Goku's entire body and his clothes received a crimson tint with the aura bristling the martial artist's hair and attire alongside the upsurge in power and speed that he received.
This was as far as King Kai had allowed the technique to be taken. When he spoke of the adverse effects and limitations of the technique, he wasn't even explaining them to Gohan but rather to Goku as the old martial arts master had hoped that, with him being a father, Goku would protect his son from such aftereffects and that he'd better understand the risks.
"Paper!" Goku yelled out as wrath and pain mixed together into something as frightening as it was awesome. With a snap, the Saiyan closed the distance between him and Lord Slug and drove his open palm into Lord Slug's face, sending the withered, evil Namekian darting back. Before Lord Slug could smash into the nearest building in his way, however, Goku bounced over him and flipped, kicking off of the same building with so much force that the building collapsed while Goku rolled in an arc to stomp both his feet in the back of Lord Slug's head and smash the Namekian tyrant into the ruined city street.
Grabbing both of Lord Slug's feet, Goku spun and released him with a Dragon Throw before vanishing before his airborne enemy with an upward-aimed dropkick to send Lord Slug soaring skyward only for Goku to vanish in a feat of uncanny speed again and appear over Lord Slug's head to drive both his fists in an ax handle slam and send the evil conqueror smashing into the street like a fiery comet so hard that it decimated the entire region of the city, shattering the city street, shaking and tumbling most of its buildings and leaving rampant fissures in the ground where Lord Slug hit it. Slug's helmet shattered to tiniest shards upon impact, exposing the withered, moss-colored skin of the ancient evil.
Goku landed by the edge of the nearest fissure, panting as he had never pushed King Kai's Fist to two times its ordinary power. Honestly, as much strain as it put on his body, it didn't feel like a deadline whatsoever, in fact, the Saiyan wondered if he could still push it even further, though the potential result seemed to frighten even him at that time. Both the beneficial and harmful effects did.
Decimating Lord Slug's legion of Evil Tribe troops with his fists and his feet alone, Gohan appeared over his father in the location of his fateful clash with Lord Slug, looking dire. Cupping his little hands together, the child yelled out a warning to his father.
"Dad, stop rushing it! You can do this without King Kai's Fist! This is exactly what Lord Slug wants! He wants you to burn through your Ki as fast as possible because he knows he can't beat you!"
"G-Gohan! But you and Chi-Chi…" Goku turned his attention to his son, looking surprised and a little relieved that his boy was okay. Chi-Chi hit through multiple skyscrapers like a meteor, emerging from the rubble covered with bruises as the towering, mechanical planetary decimation force of Lord Slug continued its cruel march onward, aiming its crushing blasters all toward the stalwart human holding them off.
"Chi-Chi!" Goku cried out but Lord Slug was eager to punish the Saiyan for his fleeting attention. A tight grip locked around Goku's heels, Slug's elongated arms had reached him from wherever he ended up after the crash and began dragging him in closer. Goku threw a wayward Ki blast to fend off the alien threat as he began vanishing rapidly to close in on the space conqueror to finally put him down.
"You know, what, Saiyan? Right now, I hate you far more than that Saiyan bitch!" Lord Slug let out a resolution that seemed to be oddly in between furious and cheerful at the same time. "What do you say, how about you surrender your planet's Dragon Balls so that I can restore my youth and we can have a proper fight?"
"I'd have loved to fight you at full power someday, but I can't let you take over my planet and hurt Chi-Chi and Gohan!" Goku declared, clenching his fist out in front of him as a warning to his opponent that his trickery won't get him anywhere. "I'm not letting you use the Dragon Balls!" the Saiyan had regained composure after seeing that his family were beginning to handle their respective battlefields and tackle Lord Slug's invasive forces all by themselves and even managed to stick out his tongue and waggle it in mockery of the deceitful Namekian overlord.
"Tsk… You bastard… I am Lord Slug, evil incarnate, a Super Namekian! You'll pay for mocking me, Saiyan, no matter how powerful you may be now!" Lord Slug roared from within the darkness of the underground depths where he lurked. Without burning through his Ki and damaging his body any further with King Kai's fist, Goku charged onward to meet his opponent while following Lord Slug's response via sensing the evil tyrant's Ki.
The two clashed in the center, emitting an expanding shockwave and crackles of violent electricity where they met. Being a skilled martial artist, Goku repurposed the momentum into a sweeping kick and got his enemy off balance. With a stout left punch, Goku left Lord Slug stunned and gasping for air as the Saiyan's fist dug in between Slug's chest and his gut. The Earth-raised martial artist spun like a swivel, throwing spinning kicks to decimate his opponent before transitioning into a mean barrage of fists that Lord Slug tried defending against but ended up coming up a bit short to. Having opened his enemy up, Goku delivered a high kick to send Slug up to ground level as he charged in pursuit after him, flaring up with crystal-clear aura.
With a resonant palm strike, Goku sent Lord Slug skidding back, flailing madly and powerless against the Saiyan's rampage as Goku took a balanced fighting stance. "Get ready!" he exclaimed.
Throwing both his fists and his kicks in a mad combination of strikes, the Saiyan overwhelmed the crumbling defenses of the space conqueror and with his final hook to Lord Slug's gut, sent him falling down on his front breathless, bleeding and battered. Goku ascended to the air with his arms together and drawn behind him. "Ka! Me! Ha! Me…!" he chanted out before thrusting his arms back down. "Super Kamehameha!"
The luminosity of the finishing stroke blinded everyone inside the city who still had the ability to see or was alive to be bothered by the immense power of Goku's finishing stroke. With the Super Kamehameha enveloping and reducing Lord Slug to a broken and tattered mess, burning up with smoke and whited out, seemingly lifeless, the Saiyan's Meteor Combination was complete and his enemy seemed to be defeated.
Gohan laid within the grasp of an Evil Tribe soldier with the foul villain driving his knee repeatedly into the child's bloodied face but Chi-Chi's one-leg missile kick busted the soldier on the spot, sending him crashing down while the mother wrapped her arms around her child, cradling him close to her chest as Lord Slug's sky-reaching battle-bots collapsed in a fussilade of explosions from Chi-Chi's blows. With that, it seemed like both Lord Slug's soldiers, his mighty battle-bots, and the conqueror himself laid beaten with only the swarm of drones filling the sky bothering the remaining Earth defense force. Though given Goku's recently liberated pair of hands, the family would soon make short work of the remainder of Slug's forces too.
Goku stared at his dying enemy. In his current condition, it might have just been that Lord Slug would not recover from this humiliating beating though it was something he entirely brought upon himself. Lord Slug's cruiser's door croaked as it opened back up, letting a pair of cloaked, mechanical dwarves with red, cybernetic gazers for eyes to rush out and approach their fallen commander from both sides.
"L-Lord Slug!" they muttered in terror, completely ignoring the settled down Saiyan looming over them right beside their beaten master.
"Take him and leave…" Goku muttered in silent, simmering rage. For the hurt that these folks put on his planet and his family, they'd never get on the Saiyan's good side. "Take the rest of your army with you and never come back."
"Y-Yes, sir!" the one to whom Lord Slug had earlier referred to as Gyoshu muttered in a cybernetic voice as he and his identical-looking partner extended their hands, forming a telekinetic field around their defeated and dying commander as they moved back toward the cruiser.
"Dad, there are more soldiers closing in from the north-west," Gohan pointed his hand, looking beaten and weakened in his mother's arms. He had more than a few nasty bruises and his forehead got cracked open by the beatdown nearing the end of the conflict before his mother swooped down for the save.
"Yeah…" Goku muttered. "If they know what's good for them, they'll join their master and leave. If they keep on raising trouble, I won't hold back!"
"A bunch of Ki are incoming, Krillin, Tenshinhan and Chiaotzu, even your father, Goku-sa…" Chi-Chi looked around, inspecting the few Ki signatures that were rushing in to join the fight. Without a doubt, they had their own fair share of trouble on the way, or else they'd have joined in far sooner. It didn't take that long for someone as strong as the Dragon Team to cover the entire Earth.
"Lord Slug!" the soldiers, all of whom seemed plenty beaten up and bleeding themselves all chanted in unison when they saw Goku staring at them with a death-inducing stare from down below and their dying commander being carried away back to his cruiser. There were cuts rampant all over them, must have been Yajirobe's work. So those goons went as far north as the Korin Tower…
"That's right, Goku-sa has beaten your ruler to a pulp so all of you better pack up and leave while my husband lets you!" Chi-Chi threatened the petrified and injured platoon of soldiers. None of them raised too much of a ruckus either, they just buckled up, lowered their heads, and followed Gyoshu and his identical ally and Lord Slug into the cruiser, preparing for their embarrassing take-off.
"Did you see that? One of the soldiers had something attached to his belt, it didn't look like any gear that they would use, looked dirty and ragged. Do you think they hurt someone?" Gohan wondered with a worried expression.
"No way, even Yajirobe should have proven to be too much for these soldiers," Goku shook his head, turning to the cruiser. "What do you think it was?"
"I don't know, like a rag or…" Gohan scratched his head, showing to his mother with his body language that he was okay floating on his own for now.
"A sash!?" Chi-Chi gasped.
"S-Senzu!" Goku turned toward the cruiser in shock. "They must have nabbed some Senzu off of Korin's Tower even though Yajirobe fended them off!"
Just as the family of martial artists prepared to rush to the cruiser, a boom of rising power froze them in place. Everyone's eyes widened in shock and despair as they've realized that the cruel evil incarnate had been revitalized using the magical healing beans only found on Earth. The soldiers must have seen one of the Earthlings use them so they knew about their mystical properties. Releasing a huff of smoke, the cruiser's door opened again with Lord Slug's toothless smirk decorating his moss-colored face gleaming in the middle of the opening.
"Back for more?" Goku grunted. He had spent a decent amount of power fighting the space conqueror, it was entirely possible that he'd not be able to beat Slug if he came at him right now.
"I don't think so, Saiyan. I think I'll be taking your offer of mercy and retreating from this planet. I have come to learn the error of my ways, you see. I apologize for the madness and mayhem I've caused on your planet and I promise to do better in my future and dedicate my entire life to reverting the damage I've caused to this galaxy and all the others…" Lord Slug sneered at Goku as if challenging the Saiyan to call Lord Slug's bluff but Goku just nodded with a pacified expression even if his family looked less eager to trust the evil Namekian.
"Fine, take off then and never come back. If you end up regaining your youth one day, I'd like to fight you again but if you're up to no good – I won't be sparing you again!" Goku warned the malicious elder who only snickered with undoubtful malicious intent as he shut the door of his cruiser once more.
"Please give us a few more minutes to power up our cruiser and take off then… It won't take long," Lord Slug's words lingered long after the cruiser door closed shut.
