“Oh my God!”, May shouted as she saw her little brother, unconcious on the ground. Her dad would KILL her if she let something happen to him, she attempted to shake him awake, “Max! Wake up!”

The others ran up to May in concern. “May! What’s wrong with Max?”

“I dunno. He won’t wake up. Do you think he’s...?”

“Ughh....”, Max moaned, “What happened?”

“Thank goodness! Max, you had me scared to death.”

“If that’s true than why are you still here?”, Drew joked

“DREW!”, Brendon shouted.

As this exchange was going on, Max finally got up. Ash, Misty, Pikachu and Brock were shocked at what they saw... Max looked quite a bit older. He was at least as old as May now. His clothes had even gotten bigger, and his pants were no longer shorts...

"Max!?" May shrieked. "Wh-what's happening!?"
Without even realizing that that a very fine, white felt was engulfing her body, May ran to her brother's side. He was doubled over, clutching his sides in agony.

"Don't know! Feel... different..." Max's body was getting larger! His already blue hair was becoming bristled, and seemed to be growing elsewhere.
Max suddenly threw back his shoulders and howled with pain.

It was then that Misty noticed his chest. On top of his sudden growth spurt, Max's chest and stomach muscles had suddenly become very well defined. She couldn't help but stare a moment as Max's toned abs made themselves clear through his tight green shirt.

As Misty and Ash gathered to help the rapidly developing young man, nobody took notice as Brock crossed his arms and glared at Max.

"It took me years to develop a body like this and that kid does it in a few seconds..." his jealousy-possessed mind whispered to itself. "It's not fair! All that work, and still not a single girl to show for it."

His eyes began to twitch with envy and frustration.

"S... sis! It hurts!" Max's voice deepened into a manly soprano as he continued to grow. His arms and legs were now just as buff as his chest. His shirt ripped down the middle as a ribbon-like tail burst from just above the seat of his pants.

"Brock, you know a little bit about medicine, right? Can't you help him!?" Misty pleaded. Try as he might, Brock couldn't hide the indignation in his voice.

"No, I've never seen anything like it."

"But we've gotta... May!!" Ash pointed to the trainer's now fuzzy face. She had whiskers! Her ears had disappeared completely, but underneath her bandana were two suspicious-looking triangles.

"Aaauggghgh!" Max gave an agonized scream, which slowly degenerated into a wolf-like howl! His mouth and his nose pushed out, slowly fusing into a short box muzzle with a canine nose at the end. His forehead sloped into a feral brow.

"He's turning into a monster!" Drew reeled and took a step back, a twinge of fright crossing his cool demeanor.

Max continued to grow and become more muscular, until finally his shorts began to strain and rip. His fingers became bulky paws, each tapering off into a viscious claw! The same happened to his feet. Finally, as Max ended his soul-wrenching howl, his hair spiked back into a light blue mane of fur.

He shakily got to his feet and held his head. The world was still spinning.
