It had been a day like any other. Just your usual evening in the city, all the hustle and bustle of a typical workday winding down as the sun began to set. The sky was filled with a mix of beautiful crimson and orange colors, the stars of the approaching night beginning to reveal themselves. It was looking to be yet another peaceful day... when suddenly the ground began to rumble quite violently! Was it an earthquake? The city had never been known for having earthquakes, but there's a first time for everything as the saying goes. The inhabitants quickly took shelter, hoping the quakes would settle, but they only grew stronger in intensity instead, along with what could only be described as deafening explosions with each powerful rumbling of the ground. And then suddenly, everything went dark. Could this be it? The Apocalypse, the end of the world as everyone knew it? As the quakes suddenly stopped, the city's inhabitants looked outside, fearing the worst... but what they saw was beyond what anyone could have expected, though it was certainly a lot... cuter than they thought it would be.

A gigantic mass of yellow was hovering over the city, visible strands of fur completely covering it. The round belly, the thick thighs, the pudgy fingers, the adorable red cheeks, the iconic bolt-shaped tail identifying him as male... There was no doubt, what was looming overhead was a Pikachu... but he was astoundingly enormous, immeasurably so even. His scale was so massive that it was difficult for the mere human mind (or Pokémon mind for that matter) to comprehend! On average, a Pikachu is typically a little over a foot tall in height. But this Pikachu was absolutely immense, he had to be at least in the hundreds of thousands of feet considering how he was looming over a roughly 30-mile wide city, let alone the nearby mountains! While some have heard of the recent Dynamax phenomenon from Galar, even the largest Gigantamax Pokémon wouldn't be able to reach halfway past one of his pudgy digits. If not for him walking on all fours at the moment, the remaining clouds in the sky would be wiped away by the mere movement of his humongous body. Stranger still, the abnormally gargantuan Pikachu had a couple distinctly unique features: thick, fluffy red hair and shining green eyes behind a pair of glasses.

"Heheheh, so this is what it feels like to be huge!" The red-haired Pikachu, known by his friends as Geoffachu, boomed loudly with a deep, yet still adorable voice, rumbling the ground and rattling buildings with the sheer power of it. Although he's a gentle and kind Pikachu, Geoffachu always wondered what it would feel like to be immensely huge, big enough to loom over whole cities and mountains. With his curiosity getting the better of him, and a certain friend of his fully encouraging him to try it out for himself, Geoffachu gave in to his desires and grew immensely huge, reaching what is typically called the mega scale, his paws big enough to flatten an average city underneath them. The massive increase in stature gave him a bit of a power rush however, stomping his way towards a nearby city on all fours, leaving massive paw-shaped craters behind him, though still mindful to watch his step so as to not accidentally hurt anyone. As he loomed over the city, he could truly feel just how big and powerful he was, his cheeks sparking with delight. The bolts emitted from his cheeks at his size must have at least contained millions of volts each, enough electricity to be on par with several hundred power plants. If he were to use a Thunderbolt at this size, it would most likely decimate anything it impacted. Luckily for the inhabitants of the city below him, Geoffachu isn't so cruel as to harm others.

Geoffachu flashed a brilliant smile down at the city. "Don't worry everyone, I promise no one will get hurt. I'm just gonna have a little bit of fun with your city." The gigantic Geoffachu made a playful cry as he raised one of his massive paws up and brought it down with a deep rumble. THOOM! It impacts the ground with a deafening roar, creating a fissure across the ground, crushing the buildings with a delightful crunch under his thick fingers. Many inhabitants were caught under his paw, though fortunately for them, Geoffachu's fur is so soft and thick that they just sink into it, like cuddling against a giant plush doll. Though they could feel some weight from it, it wasn't enough to cause any pain. Geoffachu giggles, enjoying this newfound sense of strength, slowing bringing down his other paw to the ground, setting it down in a clearly abandoned area of the city as gently as he can, though still crushing at least a couple neighborhoods under it. However, he then clenched his fingers together, squishing all the structures between them and against his thick palm, disintegrating them all into dust. "At least I saved them the trouble of having to demolish it all!" Geoffachu laughed adorably at his own silly joke. Looking behind himself, he then gets an idea as he stomps his hindpaws into the city limits. After thrusting them down, he then starts to slowly squeeze his toes together, feeling the buildings caught between them as they squish into tiny pieces. "Goooooosh, this feels sooooo goooood... No wonder some of my friends enjoy this so much!" A light blush grew across his face from the pleasant feeling of overwhelming power. "Mmmmm, man, this has been so much fun... But I think I've had my fun with all this. Sorry for all the mess, I'm sure you'll all be fine though!" Geoffachu cheered warmly as he stomped off into the distance, his large Pikachu rear and hips swaying back and forth, and his giant tail wiggling along with them. Unbeknownst to the gigantic Geoffachu however, he had a tiny watcher in the distance, observing his every action and cheering him on throughout it. "Hee hee! That's my little... er, "big" Pikabwo!"

The inhabitants of the city were in complete disbelief at what just happened. It all felt like some kind of fever dream, if not for the very clearly visible damage and massive craters caused by the colossal Pikachu assuring them that it was all very much real. Many were still in shock, especially those who got stepped on, though strangely enough, they all said that they didn't mind it at all. In fact, some even said it was rather pleasant and wouldn't mind having it happen again (leading some to call them crazy). Pokémon Trainers were left completely speechless by it all, wondering if they could get their own Pokémon to be that massive. The Pokémon themselves were awestruck, the smaller ones wishing they could be that huge one day. What was supposed to have been a normally uneventful day turned into an unbelievable yet unforgettable day of destruction caused by the biggest Pikachu ever witnessed. All the damage was sure to cost them a lot to fix, but at least, to the disbelief of everyone involved, the Pikachu kept his promise: Not a single inhabitant was hurt. And that's all that really mattered at the end of the day, as the sun finally disappears from the horizon.

For the longest time, I had been wanting to upload the commissions I got, but I felt like it wouldn't be right to just reupload them and possibly take views away from the artist. So I decided that if I'm going to reupload a commission, I have to write a story for it. Problem is, getting me motivated to write is difficult, not to mention it's very time-consuming, and considering I've been working 55-60 hours a week for the past several months, that doesn't leave me with much free time. But after Sparky drew this for me, I just felt so inspired that I had to it. I have to emphasize, I did not technically commission this. Sparky wanted to make a Macro March Pikachu pic, but didn't have the free time to do it. So I offered to let him have two months of my Patreon-reserved time to use for himself. That being said, I did not expect him to use my character for it, and it was very humbling for him to do so. Thank you so much, my big Pikabwo. u///u

This is the first time I've ever publicly written a story, so sorry if it's not the greatest. I genuinely don't think that I'm a good writer. That being said, I tried my best to put all of my heart into this to reflect the passion and gratitude I felt towards Sparky. I'm open to any genuine advice anyone would be willing to share. The main point that I wanted to establish with this story was to demonstrate that Geoffachu is still a lovable sweetheart no matter how big he gets, though if he gets big enough, he can get a bit carried away with his newfound size and power. He's meant to be a playful, friendly macro (switching between submissive and dominant depending on mood), and I hope that this story helped to portray that message without making him look evil or uncaring. Anyways, hope you all enjoyed it. I'll try to see if I can write more stories, depends on if I'm able to find any free time and the mood for it. @w@ I doubt they'll be anywhere near as long as this though.
