As soon as I had fully charged up Super Saiyan Blue combined with Kaioken, yelling, "Kaioken!" I shot myself forwards with an almighty kick to the ground, crushing it and propelling myself forwards. I screamed and just before I hit Tirek, I veered sideways, the red energy splitting  around him, and as I raised my fist, I screeched, "-x2!!!" and I landed a direct hit on Tirek's head, making him briefly reel forwards, and in that short interval, I flew around and under him, sending an uppercut kick to his face, making him fly high into the sky. I kicked the ground again, and just as my feet left earth, I upped the power of my Kaioken more. "x3!!!" and I flew at massive speed to the airborne Tirek, then once I got  directly underneath him, I punched and kicked him rapidly higher into the sky.
After a few minutes of my close combat assault, we were so high above Earth, the whole sky was pitch black despite it being the middle of the afternoon. It was at this point that I decided we were definitely at an acceptable height, and so I powered to Kaioken x4, and swiftly flew above him. 
Tirek's eyes were shut (presumably from the pain) and he was quietly cursing. I brought both of my fists up high in the air (or should I say lack of air?) and with as much force as I could, slammed both of my fists into his stomach, immediately causing Tirek's eyes to open wide and he let out a strong puff of air as his body flew back down to Earth at a speed that would put light to shame. 
I clenched my hands together and once again upgraded my Kaioken, this time to a multiplier of 5, and I slowly brought my body back, then exploded forward as if I was shot from an ultra powerful cannon. To my great surprise, I glimpsed the purple pony in the middle of space encased in a large, colorful bubble, and she was looking down to the quickly shrinking Tirek, then stared at me with awe, and I blinked. To my greater surprise, she was gone the next instant. There was purple energy residue fizzling, so I guess she might've done that same thing she did earlier. 
After that short interruption, I continued flying downwards, and I saw Tirek, 5000 kilometers from the ground, who was now beginning to recover. He saw that he was being launched straight into the hard ground and his eyes widened. He began to prepare, and my eyes also widened with worry that all my hard work would be for nothing.
So, I grit my teeth, squeezed my fists to the breaking point, and my whole body tensed an extreme amount. At the top of my lungs, I yelled, "HAAAAAAAAAA!!!!!!" my blue and red aura expanding slowly, and then, in an instant, all my pent up ki exploded outwards, increasing the size of my flaring aura by nearly 2x, and I shrieked, "Kaiokeeen...X10!!!!!!!!!!!!!!!!!!!!!!!!" the entire dimension was crushed under the force of my energy, and it ripped holes into all the other dimensions, destroying every living thing in existence...not. I would never let my energy get so unconstrained it would do something like that! However, it did send shock waves throughout the universe, and I immediately caught up with Tirek. 
Wanting to make sure my plan worked, I punched him in the face before he could protect himself from the crash landing, and he clutched his face in pain, then I kicked him in the shin, and I continued this devastating combo, using all my limbs to deal as much damage as possible, and to top it all off, I slammed my punch into his gut on the last blow, and he fell down even quicker than before. For the grand finale, I used instant transmission to teleport to Tirek's location in a instant and yelled. Then, I clenched my right hand into a tight fist, and I began charging intense ki into it, then the next moment, I punched him so hard that an explosion rocked the galaxy, and he rocketed towards the ground, smashing the battlefield into an even more demolished landscape, so that you would think an earthquake scaled 10 had erupted from the ground. 
I landed onto what was left of the ground, and I glared at Tirek, temporarily releasing the Kaioken. He lay completely still on the ground for a long time, which was fine with me, since I needed time to recover from all that Kaioken usage. Even though I'd learned to use it at near perfect level, it still took a lot out of me.
I waited and waited, for what seemed like an eternity, until I finally spoke to the seemingly unconscious centaur. "I know you're awake, your ki flow is that of someone conscious, you can't fool me into leaving," I declared, staring at Tirek, angry at him for wasting so much time. 
He still didn't get up, and my patience was really being tested at this point. "If you don't attack first, I will!" I shouted angrily. Just then, his ki flared up and he raised his head rapidly, shooting a large beam at me. I'll admit it, his trick ended up actually having an effect on me, but I still managed to get out of the way just in time. The red blast was heading right at me, about to severely injure me, but right before, and I mean literally right before it engulfed me in it's searing embrace, I kicked the rock bits underneath me, completely crushing them into dust and little pieces, sending me flying out of reach of the blast, and I landed on a faraway mountain, leaving the beam to fire at what was now a pile of debris.
I again charged up the 10x Kaioken and Tirek came galloping at the mountain I was perched on top of. I heard a squeal from nearby and I looked up to see the pony still watching the battle. I soon realized how stupid I was leading Tirek to this pony who he could easily harm despite the bubble around her. Tirek lobbed an energy blast at me and the watcher above, so I hastily used ki to create a temporary protective barrier around the mountain we were on, then I leapt out of the way, nimbly landing on the closest mountain other than the one I had just been on. 
Tirek followed suit and shot another huge beam, which I deftly avoided. I landed on the ground, and I immediately shot a Super Kamehameha at Tirek, which he countered with a huge, red beam. I thought, Now is as good a time as any to use that, though there's a good chance it won't work...eh, I'l try it anyways, it's not like anything'll happen if it doesn't work. So, I gathered up yellow ki into my hand for exactly 10 seconds, then closed my eyes and shot out the small ki blast at an expansive plain a few hundred meters away.
To my disappointment and embarrassment, it just fizzled out and made a sound like that of a fart, and Tirek cackled. "What, are you trying to make me laugh to death?" he said in between chuckles.
I blushed and responded in an abashed tone. "N-no, just let me try out this new trick again, I promise it'll work the second time!" Tirek merely shrugged and waited with his arms crossed, a small grin on his face. Darn, I've just made him more confident, come on, come on, work! I thought as I tried charging up my technique for the second time. I made sure to focus my energy even more, my blue-red aura was more densely packed, and a ton of it's energy got sucked in by my new technique. I threw up my right arm with the yellow orb in it, and hurled it at the same plain from a minute ago, and the yellow energy slowly expanded, eventually becoming the size of a mountain, in fact, it did become a mountain! 
I smiled, knowing that now the hardest part of the technique was done, so the rest would be a cinch. I charged up two more ki blasts and directed them at the newly made mountain. The mountain glowed gold for a few seconds, and then two more mountains bursted out of the one mountain, making three.
I repeated this process many times until everywhere you went for a 5 kilometer radius, you'd see at least a dozen huge hills towering above you. Finally finished, I wiped sweat from my face, and leapt onto the closest mountain to me, which stood about 75 meters above Tirek, so it was a pretty small one.
Tirek looked surprised at this technique for a few seconds, then asked, "What is that supposed to do, are you trying to intimidate me with these big hills?" darn, he always has a witty remark ready.
"Oh, come on, I was just about to make a cool speech about this technique, but not anymore, you'll just have to see for yourself what this does." I smiled and brought my hand forward, bringing my fingers towards me in a ready gesture. Tirek blasted a huge double beam at the mountain I was on, one of the rays incinerating the artificial hill, the other one shooting past, then redirecting itself at me. I jumped off the mountain when the beam hit it, and spinned towards the next mountain, which was hit by Tirek's second beam almost as soon as I landed. Dust obscured my vision, and I quickly flew outside the smoke, going to the next mountain.
Tirek once again sent a powerful beam at me, and this time I shot a Kamehameha to meet it. The resulting explosion gave me time to escape Tirek's line of sight, and I went to a small mountain far away, releasing Super Saiyan Blue along with Kaioken, and hiding my ki as well as possible.
Looking around, Tirek couldn't find me for a while, and in that interval, I grabbed something from my pocket that I'd been saving the whole time. I brought my hand out, and in it was a small, plain brown pouch. "It's a good thing I brought this along. If I hadn't, I would've lost very soon," I said to myself, dumping the only Senzu bean in there on my bruised hand. 
I chewed and swallowed on the magical healing bean and instantly, I was back to full strength, and stronger too, thanks to the power of Saiyans becoming stronger after being injured. I put the small bag back in my pocket and used instant transmission to get behind him. I then unleashed my newfound strength and fired a full power Super Kamehameha at Tirek, momentarily stunning him.
Tirek turned around and blasted at me. This shoot, get shot at, and jump routine got repeated many, many times over until all the mountains were disintegrated, and nothing but dust remained of the previously proud, tall mountains.
Tirek was panting from using all that ki, but he smiled nevertheless and spoke in between quick intakes of air. "I don't know what you were planning to do with those mountains, but now, you can't do it, I've incinerated every last one of them."
To his surprise, I began laughing. After a good 5 seconds of guffawing, I said in a very amused tone, "You know, the hills being destroyed was part of my plan! Thanks for helping me! Now, it's time to see what I really have in store for you." I raised my hands in the air, and my blue-red aura glowed extra vibrantly as I gathered the necessary energy for maximum effect of the technique.
While Tirek smiled at me, he had no idea of the fury about to be unleashed on him. Thunder rumbled across the skies again, and the poor land tired of all this once again trembled, and the sky cried from all this chaos. I'll end this fight soon, so don't worry, me and Tirek will wrap this up quickly, and I'll try to keep this land as intact as possible. As soon as I had finished this thought, I was done charging up, and I shouted, my aura flaring to twice the size of Tirek. 
Suddenly, dust that was beginning to fade solidified into millions of small rocks amplified with intensely high focused ki, and the gargantuan army of pebbles fired themselves at Tirek, creating a giant waterfall of dust exploding from Tirek as the stones hit him. Tirek grunted when the massive barrage hit him, and he was clearly angry once the dust cleared, but relatively unharmed. I smirked. The rocks that had assaulted him didn't crumble, and they were actually all intact. The battalion of little soldiers came back for a second attack, and they kept smashing into Tirek again and again. After the 10th flurry of stones, he was fed up with this, and slammed his huge fist at a bunch of the rocks, flinging them backwards. However, this didn't stop the rocks. They became smaller, but more powerful, as the energy was more focused. 
Tirek, in a blind rage, kept blasting and smashing the bits to little bits, and the little bits to tiny bits, and the tiny bits to microscopic bits, and the microscopic bits to bits of rock so small, even an atom didn't seem all that small in comparison with them. After Tirek had finally blasted his final rage energized beam at the remaining microscopic bits, he realized he was only making things worse for himself. So, he decided to unleash a wave of ki so powerful, he thought it would completely atomize the rocks, rendering them powerless. He thought.
Tirek glowed with a flame hued aura and he wrapped his hands on opposite shoulders, then whipped his arms outwards, and the glow surrounding him exploded, engulfing all the rocks in it's fiery grasp. In fact, it almost got me, but I teleported far away enough that the blast wouldn't reach me. 
From afar, I watched everything in the field of Tirek's energy being heated so much, it instantly got vaporized. I clenched my fists tight in disapproval of this mass destruction, until Tirek was finally satisfied with the pure obliteration he had caused to this land and the rocks.
He smiled, and to my amusement, he gasped when he felt the pain of ever more powerful pebbles. He couldn't think of any other way to stop this, so he simply waited, trying his best to defend against this massive onslaught.
Finally, I realized I couldn't keep this up much longer (the skill took up a considerable amount of stamina), and released the technique, causing a universe distorting explosion that ripped the battlefield into a wasteland so barren, you'd scoff if someone said this used to be a plentiful plain. Following the explosion of the persistent rocks, Tirek stood, seeming much less confident than a few minutes previously, and a lot less calm. 
"IS THIS YOUR IDEA OF A JOKE!!! YOU INSULT ME BY HITTING ME WITH TINY STONES!!?? HOW DARE YOU!!!!!?????" Tirek roared with utter, blistering fury. He then charged up an almighty amount of energy in between his horns, grinding his teeth, his eyes showing only one emotion: pure rage. The air around his ki got distorted and just then, I snapped out of my daze and held my hands together, collecting every last ounce of ki left in me into one ball.
We held our stances for two minutes, both of us staring daggers at one another, neither of us blinking or breaking eye contact for even one second. Miss winged pony, I noticed, was watching us with her jaw hanging the entire time, to which I responded with a brief chuckle, then continued focusing power into this one final beam that would settle the match once and for all.
At the exact same moment, our voices exploded, both of us releasing everything we had into this final collision of energy. I yelled, "HAAAAAAAAA!!!!!!!" directing my hands in the direction of Tirek, releasing a True Kamehameha at the very limits of my strength.
Tirek lowered his head, and thundered,"DEMON ANNIHILATION!!!!!!!" firing a blast identical to the Kamehameha except the color.
At the initial meeting of the super charged energy waves, the entire solar system flashed with a blinding light that made everyone on the planet cover their eyes for a brief moment.  Everyone opened their eyes when the light vanished, and the purple, winged pony (who was in the corner of my sight) seemed to be worried, and for good reason. Though I had just healed, and I put even the smallest drops of ki from the back of my reserves into the Kamehameha, Tirek's Demon Annihilation was winning this struggle. I got deja vu from Gohan's beam struggle with Cell, and tried to do the same thing Gohan was doing throughout, channeling even more power into the Kamehameha. Surprisingly, it worked, and the beam was advancing towards me at a slower pace, the blast of wind on me getting slightly slower, and I roared a battle cry, which actually made the beam Tirek was shooting slowly inch towards him.
I narrowed my eyes so much my eyes may as well have been closed, and I clenched my teeth tight, then forced myself to relax my whole body, putting any amount of concentration into the arms that were the only thing stopping Tirek's incredible mountain of energy from reaching my body and sealing the fate of the entire universe.
Tirek chuckled, which I nearly didn't hear over the deafening roar of the two energy giants. He then put even more power into his blast and pushed me back, as well as my beam. I planted my feet deep knee deep into the ground. However, it wasn't enough to stop the enormous force from pushing me slowly, but surely backwards, coming closer and closer to wiping out this world's final hope. With this thought in mind, I resisted Tirek, even though it would've been much easier to give up. I completely shut my eyes, and I cried out something I hadn't in well over a decade.
"KAIOKEN X20!!!!!!!!!!" instantly, my energy jumped up 2x, and I pushed back Tirek until the beams were dead in the middle, and my already huge aura of jumbled red and blue energy exploded with insane intensity. Already, I was feeling the side effects of the technique, my muscles ached, my veins throbbed painfully, it was suddenly hard to even stand, and if you didn't get the hint already, this hurt. A lot. 
I was finding it hard to even concentrate on the Kamehameha, but I knew I had to focus, so I did my best to relax, and removed all thoughts in my head, the whole of my mind and body being focused into the beam, and I slowly opened my eyes to see how my blast was faring against Tirek's.
To my appall, it was still in the middle, as Tirek had released any suppression he'd put into the attack. I bit my lip and closed my eyes, once again going into zen mode. I was startled by the loud pop that stood out clearly in comparison with the steady flow of sound resonating from the beams and their clashing. I looked to see the pony that had been watching the whole time, along with a weird looking mish mash of a bunch of different species, who looked really goofy. Despite this, he wore an expression of seriousness that didn't suit him at all, and he nodded at the pony, who nodded back.
The creature who I'll just call Chaos clawed at the air, and ripped a hole in the dimension the size of a beach ball, then literally grabbed the rip in the fabric of space and time, making it bigger and bigger. In his other hand, Chaos created a ball of black energy, which looked identical to the rip in time and space, except this was crackling with red streaks of a lightning like substance, and he combined these two balls into one even bigger one, making the black chaos time space ball increasingly larger.
Beside him, the winged pony charged her horn, the magic source sizzling with barely contained, swirling purple magic, the aura surrounding the horn getting bigger and more powerful. It was just then that I realized what they were doing, and I smiled, looking back at the beam struggle between me and Tirek. The huge masses of energy pushed at each other repeatedly, but they still stayed relatively in the middle the entire time.
I heard a faint sound as I saw Chaos and the pony had charged their attacks to full power, and they moved to beside me, releasing their full power. The powerful pony fired a truck sized beam similar to the Kamehameha, surrounding us in a vibrant layer of energy mixed with magic.
Simultaneously, Chaos unleashed his ball, the energy retaining it's shape, but a straight arc of black energy surrounded by red swirls protruding from it. The three of us were engulfed within a huge mix of powerful energy, the aura colored black, blue, and purple.
The fight was being won! The tiny boost in my attack's strength was enough to push back Tirek. Unfortunately, it seemed he still had a small amount of energy left, and he boomed with a deafening voice, "YAAAAAAHHH!!!!!!!!!!!!!!!!!!!!!!" with that battle cry, he pushed us back rapidly, but I wasn't having it.
"You can do it, you two! We just need to focus and pour out the last of our strength into this, remember, don't hold even one millionth of your power back, otherwise, Tirek's Demon Annihilation with do just that, annihilate us!"  I yelled with all the bravado I could muster in this increasingly worse and worse situation.
They both nodded, and I was about to look back at the nearing beam, but then the pony said, "Wait, if this is going to be our last stand, I don't want to do this without knowing who you are, just in case this last stand really is our last stand."
I agreed and replied, "My name is Goku, I'm a Saiyan from Earth, who are you two?"
"I'm Twilight, pony princess from this land, Equestria," the pony I now knew was Twilight said.
I looked towards Chaos, who wasn't actually called Chaos. "The name's Discord, God of Chaos and Disharmony, from this place as well. Now, if you don't mind, I would like to stop this monstrosity before this really gets out of hand." I shook my head in agreement, and together, Twilight, Discord and me looked towards Tirek and yelled a chorus that resounded throughout the land.
"HAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" all at once, our blasts literally broke our limits, and it shattered Tirek's Demon Annihilation in a split second, this ultimate beam flying towards Tirek thousands of times faster than superluminal speeds, and engulfed the, in comparison with the beam, tiny Tirek in it's ultra hot grasp, and he yelled in pain, all confidence wiped away in an instant. The result of this was an ear shattering explosion that made a resounding BOOM!!! This created a mushroom cloud explosion that the three of us shielded ourselves from, and an enormous cloud of dust was left, obscuring Tirek from view...
