“Now Gabe, like I said before, d—”

“Don’t go pickin’ fights with anybody, I know, I know…” The runty teenager chided his older brother in irritation, puffing a few strands of his silver hair out of his eyes. Standing with his arms crossed over his chest, he was the very picture of childish defiance, looking for all the world like a pouty adolescent, rather than the mature adult he fancied himself to be.

“I mean it, kiddo.” Apparently unconvinced, but willing as ever to temper his words with affection, the overbearing older brother ruffled Gabe’s head, making a mess of his hair barely five seconds after the boy had fixed it into place. Before the teenager could fuss too much, though, the tiger pushed the object of conversation, a heavy pokeball, into Gabe’s hand. “I’m leavin’ Gus to keep an eye on you, not to push your friends around.”

“I knoooow, Baz…” Gabe whined, sounding more petulant than he wanted to, and greedily snatched the pokeball when it was offered. It was immediately clipped to the first open slot on his belt, a point of pride among the other few pokemon he had managed to catch – mostly with the help of his older, more experienced brother. “You been leaving him with me since I was little, I know how this goes by now.”

“You’re still little…” Unable to help himself, twitching his rounded ears, Bazel lifted Gabe under the arms in a big hug, even going so far as to give him a kiss on the cheek, much to the teenager’s chagrin. No doubt he felt too old for such gestures, especially in public. “He ain’t seen you in a while. But he’s a Machamp now, so you guys shouldn’t have a whole lot of trouble with anything.”

“Ugh…” All Gabe could do was roll his eyes at his older brother’s overprotective ways, feeling all of three years old as he was settled back comfortably on his feet. He rubbed his forearm across his cheek as well, a pointed gesture, but all it did was make his big brother laugh out loud. “I bet he’s gonna like me better than he likes you by the time you get back.”

“Maybe. He’s always been pretty good with kids.” Before Gabe could protest, though, the tiger’s bus out of town rolled up to the public stop, and the doors slid back with a sound like a soda can being opened. With a big, toothy grin on his face, the tiger opened his arms to invite a hug, and his baby brother grudgingly acquiesced. “I’ll see you in a few days, bud. You be good, alright?”

“I will.” In a rare moment of agreeableness, the teenager genuinely fond of his big bro, Gabe wrapped his arms around the tiger’s midsection, enduring a firm pat on his suspiciously puffy backside, and gave him a quick squeeze in turn before untangling himself and backing up a couple of steps. The younger boy rubbed a forearm across his mouth, trying not to look sad as he watched Bazel move up the steps, then down the aisle of the bus to find a seat. “Come back soon, Baz!”

The two shared a wave from window to ground level before the bus closed its doors and rumbled quietly away, leaving Gabe to largely fend for himself for the next few days. It gave him a twinge of sadness to think about; for as annoying as his older brother could be, the two had been together for a long time, and he always missed the gregarious tiger while he was away.

Gabe sighed to himself, running a hand through his hair again before looking down at the new pokeball on his belt. It felt a little different than the others, most of which contained your generic tall grass fare. Although the teenager resented the implication that he needed a babysitter, the thought of having one of his brother’s most powerful pokemon at his side was almost enough to make him feel giddy.

“Just wait ‘til Toby sees this guy…” The teenager smirked to himself before turning to head for the playground, self-consciously hitching his pants up on his waist as he walked. Toby hadn’t stopped bragging about his stupid Sandshrew since the day he caught it, and Gabe was absolutely certain that the other boy delighted in making him jealous. Things would be different for the next couple of days, though.

Surely it wouldn’t hurt to show his new companion off just a little.

It didn’t take long for Gabe to make it to the playground. With school out for the summer, it was where most of the kids in town seemed to congregate, from kindergartners to high schoolers. The teenager sat on a bench near the small skate park, feet dangling, and took the new pokeball off of his belt to look it over once more.

Red and white, just like his, but a somewhat crude, rigid “B” had been scratched into the surface, a remnant from when his big brother wasn’t so big. The thought made Gabe grin a little; Gus had been Bazel’s first pokemon when the two boys were growing up together. The boy hadn’t always been the best companion to his tiger bro’s Machop, but it wasn’t very often that he got to hang around with someone runtier than himself, and sometimes the temptation to tease was just too great.

Snickering at the memory of a couple of pranks he played on the little pokemon, he put the ball on his belt once more and had a look around the park. Youngsters played on the swings and slides, and someone’s dad was obviously having a very good time making the kids sick on the merry-go-round, but no sign of Toby yet. Gabe grunted impatiently; of course today would be the day that his rival didn’t show up to gloat.

Patience was never one of the boy’s strong suits, but there was no harm in waiting for a little while. In the meantime, he plucked a different ball off his belt and rolled it around in both of his hands for a moment before pressing the release button and flinching reflexively away from the red beam that emanated from the pokeball. It was something he felt like he would never get accustomed to.

The red energy coalesced into a rodent-like shape, and it was only a few seconds more before the oldest and most frustrating member of Gabe’s burgeoning pokemon team was staring blankly at him, wiggling its nose and twitching its whiskers in a way that suggested it had no idea where it was, or what it was supposed to be doing.

Par for the course when dealing with a Bidoof.

“You’re so lucky you’re the first one I ever caught…” The teenager muttered under his breath, trying to frown at the clueless beaver, but he couldn’t bring himself to be irritated with it. The Bidoof, appropriately named Apocalypse by a much younger, much more optimistic Gabe, simply shook its fur out and scratched its ear with a back foot, much like a dog. “Why don’t you evolve or something, huh? Then maybe you can be like Gus too.”

Apocalypse looked much the same as he always did, ears twitching and tail slapping the ground as if to raise an alarm when a passing fly landed on its nose. Gabe just sighed and rolled his eyes, watching the beaver shake its head and waddle forward a few steps. Spying a couple of bug catchers nearby, the teenager stood up on the bench and pointed at a Caterpie lazily sunning itself in the field of grass nearby.

“Apocalypse, water gun that Caterpie!” Standing tall atop the bench and pointing authoritatively, Gabe tried to look and sound as commanding as possible in hopes that the Bidoof would actually do… something. To its credit, it looked between its trainer and the suggested target a couple of times, and the silver-haired boy could almost see the gears turning in its head as it processed the information. “I swear, you’ve gotta be part Slowpoke…”

He felt excitement start to build, though, when the beaver pokemon started to move in the direction of the dozing Caterpie. Slowly, as always, but it felt like progress. Gabe’s heart started to beat faster in his chest as he watched his begrudgingly beloved Bidoof take up a stance that almost looked aggressive, its tail up, its front paws spread, and its head low to the ground. Of course, it still had that dumb, vacant look on its face, but there’s only so much you can do when working with a dim beaver.

“Get him, Apocalypse! Attack him!”

Gabe was bouncing on his heels now, almost jumping up and down, as he watched the beaver. His excitement started to decay, though, when Apocalypse turned around to face the other direction, showing its backside to the oblivious caterpillar. What little that might have remained was quickly snuffed out when the Bidoof shook its butt, waggling its tail at the bug-type in a misguided effort to lower its already nearly non-existent defensive prowess.

“Auuugh…” Gabe groaned, sounding all of five years old, and slumped his shoulders, frustrated and dismayed as he watched the Bidoof wiggle dumbly. “You’re supposed to water gun, you idiot, not shake your butt at him!”

“Looks like Dumbpocalypse strikes again!” Gabe flinched at Toby’s familiar voice, feeling the hair on the back of his neck standing up and a blush already heating up his ears. Perfect timing, like always.

Toby stood nearby, his bunny ears bobbing, and his nose turned up in the air, the very illustration of teenage smugness. Gabe felt the color of his blush creeping into his cheeks, and he frowned, pressing the button to recall his rump-shaking beaver back into the safe confines of his pokeball. The teenager willed himself to calm down a little, knowing full well that he had the advantage this time.

“HEY, Toooby…” Gabe proclaimed with saccharine friendliness, forcing a grin as he hopped off of the bench and tucked his hands into the pockets of his jeans. With his Bidoof no longer around to undermine him, and the knowledge that he had Gus on his belt this time, the boy was feeling his confidence grow by the second. “How’s Dirt been doin’?”

“His name is Sandstone, dummy.” Toby huffed, haughty as ever, and crossed his bare arms over his chest, wiggling his nose in a way that Gabe had always found particularly annoying. He got up on his toes too, then rocked back on his heels, looking pleased with himself. “I bet he’s gonna evolve soon too, then we’ll be unstoppable.”

“When is your beaver gonna do that?”

Gabe scowled again, angry, and gritted his teeth while he searched for the perfect comeback. Apocalypse was a bit of a sore spot for him, despite his fondness for the oblivious creature, and over the past couple of years, Toby had learned almost all of the best ways to push his buttons. The fact that he had a cool Sandshrew, something Gabe was almost painfully envious of, only made the situation that much more annoying.

“Well, he’s just a BACK-UP now, so that’s nothing to worry about.” Biting back his temper, Gabe did his best to feign nonchalance, even waving a hand to dismiss the bunny-boy’s faux concerns. “My NEW pokemon is already fully evolved, so he’s my team leader now.”

“New pokemon?” Toby frowned, and Gabe couldn’t help but smirk; it wasn’t often that he got one over on his rival, especially lately, but he could tell that he had gotten under the rabbit’s skin. His eyes flitted briefly down to Gabe’s belt, then he squinted in careful consideration. “No way, you’re totally bluffing. There’s no way you got something new and got it fully evolved since last week!”

“No way, huh?” He was smirking a little wider, by this point; wide enough that he was almost in danger of looking crazed. With his hands still in his pockets, Gabe scuffed a foot on the ground and shrugged his shoulders, doing a bad job of acting casual. “If you wanna find out what I’m talking about, I could probably show him to you – I mean, if you wanna battle.”

“A battle?” Toby squinted a little harder. He could tell that his silver-haired rival was up to something, and although the two were evenly matched in a lot of ways, since the addition of Sandstone to his team, the bunny had been on the winning end of their little scuffles far more than not. His pride certainly wouldn’t let him refuse the challenge. “Fine! I know you’re bluffing anyway, so you’re on.”

Gabe was almost giggling, nearly unable to contain his excitement at the prospect of finally getting his revenge of the smug rabbit. He pulled Gus’ pokeball off of the belt clip once more, tried to spin it on his index finger like his big brother could, and immediately dropped it to the ground. He wasn’t willing to let that derail his momentum, however.

“Alright, one on one! Dirt, against my new pokemon.” In lieu of spinning the ball, he tossed it back and forth between either hand, careful not to drop it this time and further ruin the drama of the moment. He could almost hear the heroic theme that must have been playing somewhere, a proper accompaniment to the playground showdown with his hated (or at least super annoying) rival.

“Fine, whatever…” The bunny rolled his eyes, obviously not sharing Gabe’s flair for the theatrical, and lifted his shirt up to remove a ball from his own belt. He tossed it to the ground, where it popped open with an audible click. Like before, red light emitted from the open ball, and Toby watched as his beloved Sandstone quickly shifted from a mass of fluid energy into the yellow, tiled rodent. “Get ready for a fight, Sandstone.”

Gabe smirked again, crossing his arms again to watch the Sandshrew skitter a little circle, then settle into a defensive posture. The same posture that made it impossible for most of his pokemon to even scratch its hide. Things were going to be different this time, though.

“Are you sure you’re ready for this?”

“Yes, Gabe…” Toby sounded exasperated, rocking back on his heels again and frowning at the rival teenager in a way that made it perfectly clear he wasn’t buying into Gabe’s hype.

“Are you SUUURE you’re re—”

“YES, Gabe, let’s go! I got dinner at six!”

“Okay, okay…” Gabe waved the bunny’s concerns off with a dismissive hand, clearing his throat for a moment before holding Gus’ pokeball up high over his head. Toby, for his part, was completely checked out by this point, examining his nails while his rival reenacted the Gettysburg Address. Feeling the thrill of the moment, Gabe jumped up in the air and spiked the pokeball down as hard as he could. “Get ready to FEEL THE PAIN, Dirt!”

The ball popped open like any other, but the mass of energy inside of this one was much larger than either boy was used to. Toby immediately frowned at the sight, while his rival grinned manically, and the bunny boy only grew more mortified as he watched the energy meld into a hulking humanoid shape, four long arms, and a well-muscled body anchored by two wide, powerful legs. Gus the Machamp shimmered into existence, flexing heroically, something big brother had no doubt taught him to do.

“Ma-champ~!”

“Wha—” Toby stammered, his jaw slack and his eyes large enough that Gabe could only imagine them popping completely out of his head. Sandstone, meanwhile, had sat back on its haunches, and like his trainer, he was staring at the musclebound blue giant in a mixture of awe and confusion. “W-Where the heck did you get THAT!?”

“None of your business!” Gabe cackled like a supervillain, pushing his hair out of his eyes again. Upon hearing the teenager’s voice, the Machamp slowly straightened from his pose, each of his four arms bending and flexing, as if he was sore from being tucked in a pokeball for so long. The big brute softened a little at the sight of the nearly frantic teenager, a familiar face in a sea of kids he didn’t recognize. “Gus, stomp that Sandshrew! Now!”

“S-Sandstone, tackle him!” Toby shouted, his voice a couple of pitches higher than normal, and the Sandshrew looked over its shoulder as if to question the sanity of its trainer. Loyal to a fault, though, the rodent shifted in position for a moment before barreling at the much larger pokemon. Screeching heroically, the valiant Sandstone launched itself like a cannonball, tucking its head and rolling in the air to slam its back against the Machamp’s side.

That was the plan, anyway.

“Hey, look out!” Without turning around, clearly not worried at all, the Machamp used one forearm to brush the Sandshrew out of the air. As if it had been struck instead of shooed away, Sandstone hit the ground and bounced backwards, dazed and quite obviously overmatched, but not hurt. Gus squinted an eye at the comparatively feeble attack, looking between the fearful Toby and his shivering pokemon a couple of times.

“That’s right, he’s WAY too strong for your runty Sandshrew now.” Gabe gloated, his nose up in the air, savoring the uncontested trouncing of his most irritating rival. Doing his best to sound authoritative again, the teenager pointed at the cowering Sandstone. “Now Gus, finish him off!”

Gus, similarly unimpressed by Gabe’s theatrics, frowned, staring at the already beaten Sandshrew for a few seconds longer before looking back over his shoulder at the teenager he was supposed to be keeping a close eye on.

Looking at that smug face, the Machamp was reminded of something; probably his first encounter with his trainer’s younger brother. The memory of a broken window, a firm scolding an innocent Machop by an irate big brother, and watching while the silver-haired boy surreptitiously smirked at him from the dinner table. For Gus, growing up around Gabe had been full of such situations.

Taking one more glance at the fearful Sandshrew and the panicking bunny, deciding them no threat to either himself or his charge, the statuesque pokemon grinned, dusting off one of its biceps before closing the short distance to his temporary “trainer”.

“Uh, Gus, you’re goin’ the wrong way. You’re supposed to be destroo-IEEE!” Without preamble, the Machamp surprised the teenager by picking him up under the arms and tossing him a few feet up in the air. Gabe flailed frantically all the way up, all the way down, then continued kicking his feet helplessly after Gus caught him again. “Put me DOWN, what the heck is wrong with you!?”

“Champ, Ma-champ!” The pokemon answered in its baritone voice, using its free arms to dance fingers up the entirety of Gabe’s undefended ribcage, much as he used to watch his trainer do with his younger brother.

“Stop, STOPPIII-EEEHAHAHA!” Gabe helplessly busted up laughing, trying to twist from side to side in the Machamp’s grip as the pokemon played with him. His cheeks and ears were bright red again, and he kicked out furiously with both legs when Gus stopped tickling him. “Put me DOWN, and go beat up that Sandshrew NOW!”

“Champ-champ…” Gus shook its head as if in disappointment, looking the small teenager over as he dangled helplessly from the Machamp’s big, blue hands. Raising its eyebrows, the pokemon looked down between Gabe’s legs to take note of a familiar bulk. All of the boy’s struggling had pulled his shirt up, as well, and the muscular brute could see a band of smooth, soft white plastic that jutted up from over the waist of his pants.

“Wh-What are you do—No, Gus, stop! Not out here!” Gabe resumed struggling helplessly as the Machamp used both his free arms to deftly undo the boy’s jeans. The blue pokemon grinned playfully as it pulled Gabe’s pants down to his ankles, exposing a pair of white boxer briefs with baby blue trim and colorful stars. They were embarrassing enough in their own right, but a compromise allowed by the tiger when his baby brother clamored for ‘big boy underwear’. “Gus, STOP! I COMMAND YOU!”

And they were far from the most embarrassing thing the teenager was wearing.

“Chaaamp~…” The Machamp crooned, as if chiding the teenager, in disappointment. He gave the dangling boy a smack on his bottom, which resounded with a padded ‘wumph’, before turning Gabe around and pulling down the back of his underwear to expose a soft plastic shell, a Squirtle print directly on his bottom, and a puffy, very well-diapered butt hidden under the teenager’s childish underwear.

Gabe couldn’t do anything but cover his eyes with his hands and tuck his legs in, face burning with shame as he felt the Machamp pull the seat of his diaper back and peek inside at his baby-powdered butt, checking his pants in much the same way as his big brother often did.

“W—What?” Toby, stunned into total silence by this point, watched dumbly as the Machamp apparently went rogue and turned on its own trainer, manhandling the bunny-boy’s rival, undressing him, and revealing his underwear. The lapine teenager stared, though, as Gabe’s underwear was pulled down, and he swallowed hard at what was revealed underneath; the plastic backing, the tapes pulled tight around his scrawny hips, the Pampers logo. There was no mistaking what Gabe was wearing.

“H-Hey everybody, come look!” Toby, excitement rapidly growing at the prospect of what this meant for his rivalry with Gabe, was eager to let everyone savor his opponent’s unexpected humiliation. “Gabe’s wearing DIAPERS!”

Gabe could only groan and stay as hidden as he could, helpless in the Machamp's grip and no doubt hoping Gus would be more merciful than he had been.
