Ch. 10: Earthshaking Earth Pony Vs Master Water-Manipulating Aquos Merman
Once outside the building, Big Mac smiled as his opponent summoned the Neptune Trident out of thin air, the three razor tips glowing with Aquos energy.
"Alright, Big Macintosh, let's see if you're worthy for Pinkie Pie..." Trister grinned as he whirled the legendary Aquos weapon around himself, before setting the hilt on the ground and giving the earth Pony an arrogant grin. "Even though I said I'll go easy on you for your lack of powers, I'm not going that easy on you. You'll still have to give it your best effort!"
Trister then slammed the hilt into the ground, and a shimmering blue force field of Aquos energy, identical to the ones the other guardians used, to form around them, so that nopony and no-guardian could interfere in the fight. Marvin, Lionwing, and Pyrus simply smiled, remembering their own Courtship Battles, while their three former opponents, Drago, Helios, and Boulderon, thought back to those good old days as well. The Ponies simply watched, Kyogre and Pinkie hoping in their hearts that the earth Pony had the strength to defeat the fun loving but still immensely power Barer of the Aquos Attribute. Big Mac nodded.
Trister: I can't escape this dark cell
So many times I've tried
But I'm still caged inside
"E-yup!" he said, before barreling forward at an alarming pace. Trister's crimson eyes widened in surprise before the hefty stallion smashed into him, tackling the Aquos Merman straight into the wall of the force field, which rippled with the impact, before throwing him up with a swing of the head, knocking the Aquos Bakugan crying out in surprise into the air. He then fell back down before Big Mac socked him in the chest with a powerful buck.
The force of the kick sent Trister hurtling head over heels into the force field again, which rippled again. The Aquos Guardian collapsed to the ground, but got up in a flash. His red eyes had narrowed, and a glint of primal fierceness had appeared in his eyes.
So much for going easy on him. Trister's body glowed with Aquos energy as he let out an earth-splitting cry, and smashed the three prongs of the Neptune Trident into the ground.
Big Mac: Somepony get me through this nightmare
I can't control myself
Instantly, the ground rumbled as a massive wave of water appeared from behind Trister, and the Aquos Guardian leaped onto the top of the wave, a fierce grin adorning his face as he whirled the Neptune Trident in his grasp like a baton. Big Mac's mouth dropped open, and the weed he was chewing fell out.
Trister: So what if you can see
The darkest side of me
No one will ever change this animal I have become
Big Mac: Help me believe
It's not the real me
Somebody help me tame this animal!
"Nope..." he whispered in shock, before the wave smashed into him, engulfing him in its salty depths.
Big Mac & Trister: This animal, this animal
"BIG MAC!" Pinkie and Kyogre cried out in concern. After the wave cleared, they were relieved beyond belief to see that the red stallion still stood on strong legs, but he was soaked, and shivering violently. Trister then leaped down from the wave, and gave a devilish grin.
"So much for you being so powerless, isn't it ironic, Earth Pony?" Trister sneered, before charging at the earth stallion.
Big Mac: I can't escape myself
So many times I've lied
But there's still rage inside
Big Mac looked up in shock, before Trister smashed into his side like a wrecking ball. The frenzied Aquos Guardian then began stabbing furiously with his trident. The razor tips impaled Big Mac, leaving three large bleeding holes in his side.
Trister: Somepony get me through this nightmare
I can't control myself
"BIG MAC!" Pinkie and Kyogre screamed even louder, tears starting to leak from their eyes as they saw the Aquos Guardian brutalizing the poor stallion.
Big Mac: So what if you can see
The darkest side of me
No one will ever change this animal I have become
Big Mac cried out in pain and shock as Trister then took the shaft of the trident in both hands, and smashed it left and right, bashing the red stallion into the rock hard ground over and over again, nearly breaking his neck from the force. It left him with several bruises and cuts. Trister then pulled the trident out of the stallion's body, causing him to let out a roar of pain as the razor sharp prongs were pulled roughly out of his bleeding body. Trister then turned the trident around, and smashed Big Mac in the face with a powerful swing of the diamond-covered hilt.
BAM! Big Mac went smashing into the force field from the force. Blood spouted from the three stab holes in his side, but the hefty and muscular stallion slowly but surely got up, wiping blood from his mouth.
Trister: Help me believe
It's not the real me
Somebody help me tame this animal I have become
"Well, Earth Pony? Ready to give up?" Trister taunted, holding the Neptune Trident in his left hand while with the right waved at his direction a 'come at me, bro' gesture. Big Mac's vision went red. This... this... thing was the only obstacle standing in the way between his and Pinkie's relationship. He was getting really tired...
Big Mac & Trister: Help me believe
It's not the real me
Somebody help me tame this animal
"NOPE!" Big Mac thundered as he galloped at the taunting Aquos Merman with rage in his eyes. The Aquos Guardian saw the fury in his eyes, before snarling and grasping the hilt of his trident more securely. He smashed his front legs into Trister's chest, before bucking the Aquos Bakugan away. Trister smashed into the wall of the force field, before he fell down again, pain wracking his body from the powerful kick. Big Mac then smashed the ground with his front legs, and instantly three giant rocks were ripped up from the ground.
Trister: Somebody help me through this nightmare
I can't control myself
Big Mac: Somebody wake me from this nightmare
I can't escape this hell
Trister's eyes widened... haven't he seen this before?
Flashback Begin
The Subterra Golem then smashed the ground again, and a huge boulder was ripped from the ground and left floating in midair. Boulderon then drew back the Crusher Mace, resting its head on his shoulder as he slowly waved the mace like a baseball bat, before he swung. BAM! The spiked head of the mace slammed into the boulder with a sickening crack, and it flew through the air at a mach speed.
Flashback End
Boulderon had the strength to easily accomplish this difficult task, but the Earth Golem was one of the strongest Guardians in Equestria, if not the most strongest, as judged by that flashback, and one time, Boulderon had even lifted up one of the huge mountains in the distance to get to Fluttershy when she was trapped while trying to help a injured deer, and he was the Bearer of the Attribute of Subterra, the Attribute of strength... Big Mac was just a normal earth stallion...
Big Mac & Trister: This animal, this animal
This animal, this animal
This animal, this animal
This animal
"Wha!?" Trister cried in shock as the Earth Stallion, possessed by his love for Pinkie, and the will to finish the fight, bucked the three stones at him with incredible force. The three rocks went hurtling at him with tremendous velocity. If they landed, they could easily decapitate the Aquos Guardian, but Trister was not about to let that happen.
He began swirling his trident with incredible speed, so fast, it became a blur of dynamic motion. Water built in the middle of the spinning weapon, and Trister roared as he held the spinning trident above his head, before a giant ball of water formed in it, and he hurled it at the three rocks.
"Crouch Buster!" Trister shouted as the ball of water smashed into the three rocks. They exploded when they met, sending fragments of stone and droplets of water everywhere.
Big Mac: So what if you can see
The darkest side of me
No one will ever change this animal I have become
Big Mac panted. The effort required to do that attack had cost most of his energy to perform, and now he was exhausted. Trister panted as well, struggling to keep himself up straight with the help of the Neptune Trident's hilt embedded in the ground. That Crouch Buster had cost him most of his energy as well, as it was one of the most powerful attacks in his arsenal.
"Let's end this, earth pony..." Trister snarled in between gritted teeth. Big Mac only glared back.
"Let's... Aquos Merman..." Trister's body flared with Aquos energy as he put in all of his energy for one massively powerful attack, but Big Mac's body tightened with effort. The Neptune Trident glowed with Aquos energy, and formed... into a giant cannon, not unlike Pinkie's own. He then placed the cannon on the ground, and aimed the muzzle at Big Mac.
Trister: Help me believe
It's not the real me
Somebody help me tame this animal I have become
Big Mac simply snarled before smashing his front legs into the ground with even more force. A huge rock, nearly twice the size of Dialga, was ripped up and left floating in the air. His hind legs then tightened as the muscles writhed below his skin. He was gathering force for the final buck. Emerald eyes glared into crimson eyes, and they both narrowed.
"HYDRO CANNON!"
"EARTH IMPACT!"
Big Mac & Trister: Help me believe
It's not the real me
Somebody help me tame this animal!
With a roar, Trister's cannon belched out a giant torrent of gleaming water, while Big Mac drew back his hind legs, which were literally jumping with the force contained, and bucked the rock as hard as he could. The rock went speeding at the speed of light, and it neared the torrent of water...
KABLOOSH! With a bellowing roar, the rock actually missed the Hydro Cannon, and the two attacks went towards their respective targets...Emerald and crimson eyes widened, and they both whispered out two words...
"Whoa, Nelly..."
Big Mac & Trister: This animal I have become!
KABLAM! The rock smashed into Trister with a sickening crack, and smashed the Aquos Guardian into the wall of the force field, causing a wall of dust to surround him from the force of the impact.
"TRISTER!" Pinkie and Kyogre screamed.
KABLOOSH! The stream of water blasted into Big Mac with the force of a juggernaut, propelling the Earth Stallion into the other side of the force field, causing a huge spray of water to surround him from the force of the impact.
"BIG MAC!" Pinkie and Kyogre cried out again.
After the dust cleared, the force field crumpled down around the two downed combatants, and Pinkie and Kyogre hurled themselves in, each running up to their respective love. Big Mac lay in a crater, his body and mane now soaking wet, and his eyes closed. The gaping holes on the side of his body, inflicted by Trister's Neptune Trident, still gushed blood like a crimson waterfall. Pinkie's eyes glimmered with tears as she cradled Big Mac's limp head in her hooves.
Trister was on the ground, his eyes closed as well, with fragments of the boulder resting on his limp body. He had two broken ribs from Big Mac's concussive bucks, and from his mouth dripped a small stream of blood. Kyogre cradled his limp body in her fins as well, tears leaking down her eyes.
"Heal Pulse." Kyogre whispered, as her body glowed with energy, and two pulses of healing energy came out of her body. One went into the limp body of the Aquos Merman clutched in her flippers, while the other went into the limp body of the red stallion. With a whoosh, they instantly healed the two combatants. Trister's broken ribs mended themselves, and the bruises and blood vanished. The three stab wounds in Big Mac's side healed themselves as well, and the water covering him vanished.
"K... Kyogre?" Trister asked softly as he opened his eyes. Kyogre smiled, tears leaking down her cheeks as she hugged the dazed Aquos Guardian tightly. Big Mac's eyes fluttered open as well, and he groaned in pain before looking up into the eyes of Pinkie.
"Pink... Pinkie?" the dazed stallion whispered, as Pinkie cried out in relief as she wrapped him in her hooves.
"Trister... Big Mac... We thought we lost you..." Kyogre and Pinkie whispered. Trister and Big Mac simply returned them.
"It's gonna take more then a water gun shot and a tiny pebble to get rid of us, girls." they chuckled. Trister then slowly got up, and walked towards Big Mac. Big Mac then got up, and waving Pinkie away, trotted up to Trister as well. The Hydro Cannon turned back into the Neptune Trident, and vanished in a flash of light. Big Mac then held out his hoof, and Trister shook it with a smile.
"You are truly a worthy and honorable opponent, Big Mac. Can we be friends?" Trister asked. Big Mac simply smiled in reply.
"E-yup." Trister simply smiled back in response, before asking the red stallion a question he had been itching to ask ever since they had returned from the labyrinth.
"Big Mac, can I take Kyogre as my mate?" The merman asked. Big Mac simply grinned back.
"E-yup." was his simply response. Trister smiled as he let go of his new friend's hoof... only to be greeted by Kyogre as she tackled him to the ground, a smile adorning her lips as she kissed the merman passionately. Trister's eyes widened, before he closed them and returned the kiss with a smile, his arms wrapped tightly around them. Big Mac smiled at the embracing guardians, before Pinkie trotted up to him.
"That was some intense battle, huh, Big Mac?" the pink earth Pony asked in a hyperactive fit, an enormous grin stretching across her face.
"E-yup." Big Mac replied with a smile as he tilted Pinkie's head up and kissed her. The pink Pony blushed before closing her eyes and returning the kiss.
Caso grinned as he withdrew a pastel and a paintbrush out of thin air, and began rapidly drawing the two couples.
"After I'm finished this, this shall be my greatest masterpiece!" the artist cried as he painted the picture. The three boyfriends and their guardian friends simply grinned, surprised by the fact that the battle was a tie... Celestia and Arceus nodded, happy that the Courtship Battle ended in a positive note...
