Sonic: Survival of the Weakest - Chapter 10: Come From Behind Victory (Patreon)

This was certainly the climax of the bout, no matter how you looked at it.

Silver, dressed in his starred white diaper with the blue mittens and baby bonnet, was approaching an extremely dizzy and dazed Sonic the Hedgehog. 

The blue hedgehog was teetering back and forth, staring out ahead with a goofy, cross-eyed gaze straight ahead with his speedos pooled around his ankles and showing off his Seasame Street briefs to the anxious and excited crowd. They were glad to be so far away because the constant farts Sonic kept letting out was telling them all that the laxative was starting to really work it's magic.

Sonic grumbled as he tried to wipe the goofiness from his consciousness. Silver was on him and he couldn't let him win...!

"Come on Sonic~!" Amy screamed, pressing her hand against Shadow's face to keep him from shouting in favor of Silver. Shadow grunted and tried to kick her off.

"Alright. Time for the big finale." Silver grinned and made his psychokinesis drift all over Sonic's body. He smirked and raised his dangling body way up into the air. 

"O-Ohhhghhh..." Sonic made a grunting noise. His body was super stiff. He was about to actually mess his undies in front of this large crowd! 

His bowels were willing and ready to let themselves go. He knew that he had no more strength left within them to hold the mess back. Yet it didn't come out... Why though? Was it Silver's powers?

When it came to Silver's powers he was only really able to speak. Maybe his body would expel it when Silver dropped the psychokinesis. True or not, perhaps it was his chance to play to the white hedgehog's ego. 

He didn't have much time!

"Oh dear. It's going to be quite the impact once he's dropped from so high." Vector said, cupping his hand over his eyes as he looked up.

"Indeed," Omega concurred. "His body will make quite a satisfying splat once it hits the mat. He'll turn into chunky blueberry paste."

"... Sounds... delicious?" Chip said in response with a sweat-drop.

Silver began laughing as he held Sonic in the air. "Alright everyone!" Silver began to address the crowd. "Who's ready to watch the blue bomb drop?"

Everyone cheered and pumped their fists, shouting in unison for Silver to "DROP HIM! DROP HIM! DROP HIM!"

"Welp," Silver sneered."Don't want to disappoint the audience."

This was Sonic's last chance!

"I GOTTA MAKE A POO POO!" Sonic shouted aloud suddenly.

The sounds in the audience weakened a bit. They were stunned that something so emasculating had just exited the hedgehog's mouth. 

Eggman snickered so hard he bent over with his hand covering his mouth. That set off a chain reaction of laughter that reverberated throughout the entire audience.

Sonic looked all over and felt his cheeks flare up with embarrassment. He should have put that more delicately.

Silver was laughing too of course, not feeling much sympathy for Sonic at the moment.

"Oh really? You can't go poo poo or something?" Silver asked.

Sonic shook his head, reacting like a toddler a bit. "I... can't because... of your powers... it's locking my bowels in place... j-just let me go so I can make a mess..."

Silver's grin grew even wider. "... Alright then. But just your lower half."

With that, Silver made the psychokinesis disappear from his waist downward. Immediately, Sonic's eyes rolled a bit as the subsided gurgling grew louder once again. He puffed out his cheeks and his legs spread out in front of him as his loosened bowels relaxed themselves.

The jumbo tron, of course, zoomed in on Sonic's backside and took in the sight of him loudly filling in the seat of his underoos!

"HRRRRGHHHAAAAAAAGH!" Sonic let out this really humiliating grunting noise as his briefs bloated up in the rear end while he was being suspended in mid-air.

The laughter from the audience was reaching a decibel of strength one could only dream of. Even Vector and Chip at the commentator's table were practically on the floor. Amy had to chuckle herself and couldn't even chastise Shadow when he fell back in his seat with a laughing fit.

Tails blushed as he looked on. "Oh boy... it sure is something else, witnessing your hero take a dump in his Sesame Street briefs in public."

Silver was laughing to the point of tears. He kept Sonic suspended of course but the fact that Sonic's lower half was free was all he needed.

Sonic finished his waste expulsion and let out a happy sigh. "Ohhh... yeah... b-better... n-now than..."

He swung his now free foot back and then kicked forward super hard! 

His shoe flung off his foot and zipped like a rocket straight towards Silver, beaming him upside the head!

Silver stopped laughing and was flung back. His psychokinesis released itself fully just then!

Sonic grinned and fell... on his feet!

He was in messy undies but he didn't care right now. Silver was off balance!

He zipped forward at super sonic speed and smashed his fist right into Silver's gut with a strength and pace of an angry Superman!

"GGAAAAAAGH....~!" Silver's eyes widened and spit flung from his wide open mouth as the hit dented his stomach. 

The fist was in so deep it might as well have exited out his back.

Sonic wasn't done of course.

He grabbed Silver around his waist, planted his feet firmly on the ground and smashed his head hard onto the mat!

Silver's butt stayed stuck up in the air for a bit before his body collapsed in a weird looking pretzel like position. His diapered bottom was still sticking up but his arms and legs were criss-crossed while his head was on the mat.

He looked dreamy eyed and drooled, intensely confused by what was happening.

Sonic stomped on over to the edge of the ring and grabbed a few items from the crates over the edge. One was an electric poker. Another was a live crab. Another was a more drinkable, more fast acting laxative.

Sonic stomped on over to Silver and pulled back his diaper, dropping the snapping crab into it while he was dazed.

"Rise and shine." Sonic sneered.

SNAP! SNAP! SNAP!

"YEEEEEEEEOWWWWWW~!" Silver suddenly rolled about and shot up, grabbing his butt as the angry crab began throttling everything that the diaper was covering up. "NOOO! I-It's pinching at EVERYTHING! GAAAH!"

He sounded like such a girl. The audience, of course, had switched sides on a dime when they saw that it was Silver doing the humiliating stuff this time. 

He began running around in circles, jumping up and hollering with each snap the crab made onto him. He did this until Sonic grabbed the back of his diaper again, yanked the crab out, punched him in the face to force his body to spin around, then jabbed the electric poker into Silver's chest!

Silver straightened out and jittered with his teeth clenched and his eyes crossed as the surge of electricity flowed through his body!

Of course, the camera zoomed in on Silver this time, taking in the yellow tint that spread on the front of his diaper as he peed himself.

Sonic took the electric poker off and tossed it back, stomping over to the teetering hedgehog who was smoking a bit and not at all in a position to fight back anymore. He had an advantage but lost it...

Sonic cupped Silver's face with his hands and grinned at him. 

"Feeling good?" Sonic asked.

Silver's eyes dropped and he drooled. "P-Please... d-don-"

Sonic shoved the instant liquid laxative bottle into Silver's mouth and held him firmly. Silver squirmed around but it was useless. He wasn't getting out of this one. The laxative poured down his throat, and unlike the pill that had to settle in Sonic's stomach before it activated, Silver immediately felt the violent gurgle upset his poor stomach!

"He's... gonna explode..." Vector muttered.

"Yes indeed." Omega rubbed his hands down.

"HURGHGAH~! HRGAHAJKK~!" Silver fidgeted and jittered every which way and that. 

Sonic then smashed his head into Silver's for a nice headbutt.

Silver stumbled back, eyes rolling and stars circling his head. He smiled stupidly and cupped his head with his hands, dreamily staring ahead.

"Ohhh boy... wook it momma. I'm a super star! Evweybody's watchin' meee~!" He suddenly twirled around and shook his diapered butt at Sonic with a sweet little giggle.

His butt dance was amusing but it was clear he was doing it because his mind was scrambled. So it was time to put him down.

Sonic sighed and stepped on over to Silver. He didn't exactly look cool since his briefs were full of a big smelly mess but he'd win back some points doing this.

"Time for nappy time." Sonic swung his foot up in between Silver's legs while he was in the middle of his butt dance. Silver froze, his goofy face plastered there as the pain shot through him. 

Silver fell over but was grabbed by his spines from behind. Sonic then flung Silver up and smashed him onto the mat yet again. He then grabbed his leg, spun him around, then shot him into the corner post!

Silver bounced off of it, tumbled in the air, then landed in another heap on the mat. His rolling eyes and fluttering eye-lids signaled to Sonic that the unconsciousness was setting in.

BLAAAAAAARHGH

Then the filling of Silver's diaper as he laid unconscious with his bottom up signaled that the unconsciousness had finally taken over. 

Silver was unconscious. He had blown his one chance out of this mess. It was over.

"SONIC WINS AGAIN!" Vector shouted.

The blue hedgehog pumped his fists up before he felt another cramp. "HEEK! G-GOTTA GO! THANKS!" Sonic zipped through the ropes, tripped, fell on his chin, got up, wobbled with crossed eyes, then grabbed his butt and ran off to the bathroom, feeling more of his mess leak out into his underwear. 

Everyone took to laughing as he rushed by. Of course they weren't on his side.

Silver was gonna have to live with his messy diaper until he woke up. No one was going to change it for him.

He was dragged off roughly by his leg to the infirmary. With Eggman's tech, a speedy recovery was well assured...

-------

"ALRIGHT!" Eggman grinned and pointed at the crowd. "We're down to three losers. The biggest losers of this collected group!"

On the screen were the faces of the three remaining contestants.

Miles Tails Prower.

Charmy Bee.

Silver the Hedgehog.

"Now then, the next match will be the baby fox versus the baby bee." Eggman snapped his fingers and the ring transformed itself to look more like a giant playpen for babies.

Tails and Charmy's jaws hit the floor.

"AHAHAHA~! Baby wrestling. Ain't it great?" Eggman smirked. "Since I have the ability to fully recover your energy in the back, there's no need for the loser of this fight to worry about fighting another round after this."

Tails and Charmy sweated, stealing glances at each other. The crowd was cheering and with each cheer the two of them could feel the blushing grow on their faces. Charmy was still dressed like a baby girl with a skirt that barely covered him. Meanwhile, Tails was still in full baby garb. 

This was going to be a very interesting moment of truth for the both of them.

Tails and Charmy entered the "playpen" and stood across from one another.

"This is like... a caged match..." Charmy mused.

"Uh... yeah... let's... look at it that way." Tails sighed.

Rouge rang the bell. "Alright. Time for the Penultimate match."

Tails got serious.

Charmy did as well.

"Let's see who's the bigger baby then." The two of them grinned evilly, speaking in unison.

They were in agreement. 

No mercy.
