A/N: Wow, this is a long time coming. Sorry to keep y'all waiting.
Slug's ship pumped out clouds of smog, the planet slowly becoming darker and colder. The demon Namek watched the planet's slow death from the bow of his ship, a cruel smile present on his face. This was to be the tip of a supply line that would conquer the known universe and beyond. Soon, all would hail to Lord Slug!
Meanwhile, outside the ship, Medamatcha and Angira spotted something flying towards them.
"What i-" the blue skinned alien began before the flying figure disappeared from sight. The words died on Angira's lips as a burning pain appeared in his chest. He looked down, his body convulsing and quivering from the hand that had penetrated his heart. With a pitiful cough, Angira fell from Freeza's arm, causing Medamatcha to try and run for the ship. A flash of light came from Freeza's still extended hand before the frog like creature even made it a single step. Medamatcha gurgled as he fell, a finger thick hole in his brain from the Death Beam.
"Who assaults and defiles the crown jewel of my empire?" Freeza asked in a voice like ice, casting his gaze upon the ship. "I suppose that the owner of the ship needs some motivation." With that, Freeza's eyes flashed, sending forth a bolt of pink light and blowing open the port engine of the ship. "Whomever owns this ship...show yourself!" the Arcosian commanded, slapping the ground with his tail.
From the smoking wreckage of the engine, a figure emerged. He had green skin and wore yellow garb with a purple helmet.
"Well, well, this was quicker than I thought" Slug chuckled as he looked at the angered prince before him. "I hadn't expected you for a couple of hours. Still, might as well get done with this coup quickly"
"Coup? Hoho, I think you have me confused with someone weaker" Freeza chuckled incredulously, a finger going to his mouth as he chuckled. "Don't you know who I am? I am Lord Freeza, you are nothing but a slug beneath my foot" the tyrant boasted, zipping forward in a display of great speed. Freeza expected to feel the alien's face yield under his fist. Instead, the intruder's hand shot out, grabbing Freeza's hand before it could hit. Freeza was too shocked to react to the knee that rammed into his stomach, knocking him away and causing some spittle to fly from his mouth.
"Well, you're right about one thing. I am called Slug. I want you to remember that while I'm killing you" Slug snickered, powering up his purple aura in a single burst and charging forward. Freeza's vision went red and he did likewise, slamming their shoulders together in a burst of power and ki. Freeza felt indignity and rage burn in his heart. How could a random creature such as this be so powerful? The two fiends burst away in different directions, firing blasts at each other as they did so. The purple balls that went for Freeza missed, but Freeza's pink barrage hit true, sending Slug crashing to the ground.
"Heh, you were all talk" Freeza sighed in relief, trying to regain his composure as he lighted down about ten feet from the still body of Slug. Suddenly, Slug's arms extended far beyond what they should and grabbed Freeza. Freeza was surprised by the move and was unable to react in time to avoid the arms grabbing his tail and beginning to slam him repeatedly into the ground.
"And here I thought that the great Freeza wouldn't fall for the old playing dead trick" Slug taunted as he got to his feet before power slamming the Arcosian terror into the ground with all of his might. The tip of Freeza's tail broke off in Slug's hands, causing the green alien no amount of joy as he tossed the disembodied appendage at the crater Freeza was currently in.
"DAMN YOU, DAMN YOU, DAMN YOU!" Freeza screeched, icy ki surging from his body as his anger reached the breaking point. How dare this creature mock him?! He would pay! Lightning crashed down on Freeza, incredible power waxing as Freeza transformed. Slug shielded his eyes from the maelstrom, a small shiver of nervousness growing inside of him. Could he really win? The light faded away and Freeza stood there, now streamlined and in his true form. "Your death is at hand"
Slug shook away his nervousness and gave a battle cry, flying for Freeza and throwing out a barrage of punches and kicks. But no matter how hard he tried, he couldn't touch the Arcosian. As Slug prepared a double axe handle, hot pain exploded across his body. Froth and blood came from his mouth, the invader staggering backwards. What had hit him?
"A single attack while I'm trying and you fold. How pitiful" Freeza spoke in a calm voice, a small smile across his face. Slug's eyes bulged as he struggled to stand, only to be slammed back down by a snap kick from Freeza. "If you must know, your impending death will be excruciating" Freeza sneered, giving Slug a look of utter revulsion. Slug stood once more, giving a hacking cough. No, a laugh.
"Heh...you think that's all it takes? I'm not at full power yet" Slug chuckled, tearing off his helmet and gloves.
"A Namekian? Pah, now I know for certain you are bluffing" Freeza growled, disgust written across his countenance. "Go ahead then, show me your grand power"
"With pleasure" Slug grinned, holding his arms at his side and letting out a bellow like some sort of primitive animal. Instantly, his ki began to grow...followed by his body. Freeza sputtered and gaped as he looked up at the now giant Slug. What the Hell was this? "My turn!" the giant Slug roared, swinging down his arm with shocking speed. Freeza dodged out of the way, shooting up in a burst of red ki. But he was caught by Slug's other arm, slapping Freeza away like one would slap a fly. Freeza righted himself quickly, his eyes bulging in anger. How could this be happening?
"DIE, DAMN YOU!" Freeza screamed, firing off a kiai at the giant Namekian. Slug fell on his back from the attack and lay still, debris falling onto his massive chest.
"Gotcha!" Slug laughed, firing off the Darkness Eye Beams in an attempt to catch prince offguard. The beams hit dead-on...then the Freeza they hit dissipated.
"Fool me twice..." Freeza sneered, his true self behind Slug's head. Slug managed to let out a confused grunt before his brain ceased function, a man sized hole appearing in his skull from a Death Flash. "Feh, what a disgrace. Being forced to use 7% of my power on a mere slug" Freeza grumbled bad temperedly. It would take a long time to fix his capital after this mess
