Sparky was on vacation! The traveling Pikachu was finally able to arrange a visit to the Galar region, and he was having a blast. The Gym Challenge was in full swing, giving him plenty of opportunity to see giant Pokémon duke it out. Sparky had around his neck a large camera capable of housing 1000s of pictures, and he’d already used a chunk of its capacity at said battles. The huge looming Pokémon rattled the stadium to its core every time they fought, and Sparky was an avid fan. Today, however, the stadium was empty. Sparky had come when there weren’t any battles slated to get a feel for the battlefield himself. He never saw himself as a true contender or fighter, but that didn’t stop him from envisioning himself, fighting on his own, harnessing the energies required to grow to stomp his fiery opponents into submission. Sparky was getting lost in the brewing daydream, his looming presence dwarfing even the stadium, goggles magnifying the sun’s rays intensely…

THOOM.

Sparky was rocked out of his daze in an instant, tumbling head-over-tail to the ground, camera tumbling several feet away. He grunted and was trying to pull himself back to all fours when another earth-shaking BOOM made him flop belly-first. “Ack! W-what?” he said in confusion, shaking his head and peeking up. His heart surged when, instead of a stadium, his vision was encompassed by a mass of yellow fur. Craning his neck higher up, Sparky found himself laid before a Gigantamax Pikachu! The looming Pikachu’s tail shone brightly, sporting many jagged curves. Rolls of pudge were apparent on the huge Pikachu as well, hips thick, arms stubby, legs and paws as wide as a stadium seating section. Sparky’s heart pounded as he stared up from his vantage point, largely blocked by a sagging Pikachu stomach. A furious blush crossed his features as he tried to babble out some words, but only incomprehension spewed forth. The giant Pikachu’s head angled down and his eyes bore down on Sparky, a slow smile brimming on his face. Sparky flushed a deeper crimson, quivering despite no more stomps happening for the moment. That Pikachu looked familiar. “W...who are… you?” It couldn’t be the Pikachu, could it? There was only one way for Sparky to find out!

“Do you have a trainer?” Sparky shouted, his voice squeaking from embarrassment. Giant Pikachu ears flicked, Sparky wincing from the sudden wind that blew down as a result. The rapidly-reddening Sparky blushed deeper when he got the reply:

“Pikapi.”

Sparky shuddered. It was Ash’s Pikachu! Looming over him, not 10 feet away, towering taller than the very stadium he was in. “O-oh g-gosh!!!” He instinctively reached for the camera around his neck, only to remember it had tumbled away. He squeaked and started to crawl towards the fallen camera, but froze when the looming Pikachu ahead of him lifted a stubby leg. Sparky blushed, seeing the plump Pikachu rear from under all that mass the Gigantamax Pokémon possessed. Then the giant paw came slamming down with a KRAKOOM, right atop Sparky’s camera. The foot scrunched back and forth before slipping to the side, a crumbled crater now standing in place of Sparky’s camera. “Wh-what?” Sparky gawked in confusion. He crawled along further to see the remains of his camera, crushed to bits. “My pictures!”

Pikachu’s smile deepened. “Pikaaaa,” he roared out, Sparky’s head snapping up. His eyes narrowed to pinpricks when he saw the sole of Pikachu’s paw, lifted again, falling to earth right over him! Sparky squealed and threw his paws in the air, waving madly...

“No no no Pikachu stooop!” THHHOM! Sparky was compressed to the battlefield, tons of Pikachu paw compressing him against it and molding all around him. One cheek was to the field, the other against fur. “Pika!” Sparky cried, squished uncomfortably but not in any real danger form the soft pads. Unlike his camera, Sparky was rather malleable! Nevertheless, Sparky writhed beneath the sole of Pikachu’s paw as it twisted and dug into the ground, a crater crumbling to life all around Sparky in the process. After a few more playful compressions, Pikachu lifted his enormous foot up, to let Sparky slide off and fall to the ground. “Chu...”

Pikachu’s cheeks sparked, taking out a few stadium lights as the bit of static he’d built up discharged. Sparky stared straight up into the sky, hearing each massive BOOM of a footstep from Pikachu as they grew louder and closer. In no time at all he was staring up at the looming chubby Pikachu again, belly first, then legs straddling either side. Pikachu was looking down, chubby rolls of fat from his chin apparent, Sparky just able to see the muzzle and eyes and all. Pikachu sneered, then walked along further, right past Sparky. The little Pikachu strewn out on his back wiggled his limbs, trying to stand, but was too busy staring, blushing furiously as the looming Pikachu butt loomed right over head. The giant glowing tail swished back and forth eagerly, and in no time at all the giant Pikachu rump encompassed Sparky’s entire view. “P-Pikachu...” Sparky squeaked, blushing bright red and unable to hide his embarrassment.

Sparky was enamored by the view, not questioning why Pikachu had stopped walking. Then the butt drew nearer. Looming inches from Sparky’s face. “W.. W-wha, no!” Sparky flinched as the enormous rear drew closer, but it paused… Then Pikachu leapt 30 feet into the air! Sparky felt the earth rumble when Pikachu pushed off, large grooves in the battlefield left behind. The looming Pikachu soared up, and then gravity took over. Pikachu’s paws were out in front of him as he careened butt-first to the ground, Sparky right in the center of the massive ball of pudge of fur. “P-piikaaaaaaa–” SCROOOONCH!! Pikachu’s plump butt crushed to the ground, Sparky’s squealing cut off as he was awash in plush Pikachu butt. Sparky’s legs and tail were flattened to the ground, belly squashed tightly along with his head as all that weight was his whole world for several moments. He heard Pikachu laugh, whole body shaking, earth below quaking as a result.

When Pikachu finally decided to stand moments later, Sparky was at a loss for words. So squished and uncomfortable but as red as he could possibly get. Pikachu leaned forward to smack to earth on all fours, belly blobbing and squeezing out to his sides, and Sparky glued to his rear end, right around the center, below the tail. Sparky groaned as he slowly peeled off and tumbled into the enormous crater shaped like the ginormous Pikachu’s rump. Dirty and groaning, he still couldn’t help but stare at Ash’s Pikachu, still on all fours, slowly turning in place, every footstep rattling Sparky’s bones. Pikachu’s whole head came into view, upside-down from Sparky’s perspective. The giant head blotted out the sunlight and covered the whole crevice, his muzzle completely engrossing Sparky’s view. “P-Pikachu… I love you...” Sparky squeaked out with a weak smile, still red despite all the playing Pikachu was doing.

Pikachu’s nose twitched as it sniffed, then he smiled down at Sparky. He’d had enough fun with the tiny goggled Pikachu for now, and slid a large stubby arm down into the crater. He extended a paw and settled it right in front of Sparky, who slowly pulled himself up from the ground and shook the dust and dirt out of his fur coat. Still beet red, Sparky slowly crawled onto the offered paw. Once settled, Pikachu lifted Sparky up and out, gently bringing him up to one of his chubby massive cheeks. Sparky flinched as  it drew near, the electric sac alone more than big enough to rub against Sparky. It does so, Pikachu gently nuzzling to the comparatively-small Sparky. “P-Pika...” Sparky blushed furiously, nuzzling back some, then propping himself up on two legs with his fore paws up against the cheek. He leaned in and gave it a little smooch, a “chaaaa” reverberating from Ash’s Pikachu as a result. Sparky was lifted higher still, the paw tilting to slide Sparky down onto the furry expansive muzzle. Sparky landed with a quiet flop, now straddling the muzzle and between two very large Pikachu eyes. The smiling Gigantamax Pikachu purred when Sparky gave him little pets. “H-hello,” Sparky was able to say formally.

Ash’s Pikachu responded in kind, making happy noises, though stopping when it noticed  one of the many pieces of destruction in its wake. Sparky was surprised to see Pikachu’s ears wilt some. “Pika...” he murmured despondently. Sparky was quick to shake his head and wave off the looming Pikachu’s sudden depression.

“Oh no no no, the camera? Don’t worry about it! I’m sure it was an accident!” Sparky said. “I’m sure you just got carried away. I know how that is!” Sparky gave a beaming smile to Pikachu, whose spirits rose at the words of assurance. The sunlight was blotted out and Sparky looked up to see a massive stubby Pikachu paw looming over him, flabby arm descending as it gently pet over Sparky’s head and back. Despite the size difference, Pikachu was careful enough to gently scritch Sparky’s mane and down his back. “Chaaaa...” Sparky purred delightedly, falling to all fours and arching his back. After a few moments, Pikachu fell back to all fours, his muzzle held horizontal so that Sparky wouldn’t slip off.

Sparky crawled up the long journey to the tip of the muzzle, leaning up against mounds of cushy fur that rested between the eyes, and lazed. He crossed his fore paws and got comfortable, splaying his hinds and watching the world from a Gigantamax Pikachu’s point of view. Pikachu was lumbering out of the stadium now, his path into it self-evident, Sparky noted, the trail of destruction quite obvious. He even placed an educated guess where Pikachu had initially grown, the origin point of the trail not too far out of the stadium. During the short, thoom-laden jaunt, Pikachu told Sparky all about how he was still getting used to being so big, and how the effects didn’t appear to last long outside of certain areas in Galar, including the stadium. Ash made the process much easier, but it appeared the growth could be completely spontaneous, as demonstrated recently! Sparky was only half-listening, still a blushing mess, though without the constant looming threat of paw steps or rump sits, he was more in control. And learning a lot!

It was certainly worth the price of a single camera.

Once a certain distance from the stadium, Pikachu began to glow. Sparky sat up, just as with a VWOOOMP, Pikachu shrunk a little. Then again. And again! Sparky gasped as he tumbled downward, bouncing against Pikachu’s soft furry head with each pulsating shrink. Several more pulses later and Sparky, judging himself close enough to the ground, used the latest bounce to jut forward and land on all fours. When he turned, he saw Ash’s Pikachu back to his normal self. Pikachu scrunched his eyes and shook his head, then opened them with a smile. “Pikachu!” Sparky beamed and darted over to hug him. Pikachu embraced the hug with a happy squeak, hugging back.

After the embrace, Sparky’s nose twitched. He sat back and sniffed the air again, and once more smiled. It was almost dinner time, and Ash was probably waiting for him. Sparky watched Pikachu start to dash away, when he paused, on all fours. He turned his head and looked to Sparky, pointing ahead at a nearby, still-intact building. “Pika! Pika,  Pikapi!” He then made a “come here” gesture. “Pika?”

“Dinner? With you? And… a-and A-Ash?” Sparky nearly fainted. He wobbled, taking a couple drunken steps forward, before shaking his own head rapidly and nodding. “Absolutely!” He moved up to Pikachu and the pair rubbed their squishy cheeks together affectionately, Sparky’s far more reddened.

“Chu!”

The pair of Pokémon giggled and darted off together, Sparky enjoying a star-struck evening with Ash’s Pikachu and the trainer himself.
