Duchess’s eyes shot open. With a rush of adrenaline, she jumped to her feet. "N-nice try!" she wheezed out, her legs shaking beneath her, "But I've..still…got 1 HP left!"
Angelys' eyes widened. The Mega Lopunny put a paw to her mouth as she quietly gasped in surprise.
Professor Pearwood looked up from her crying. She wiped the sleeve of her labcoat across her face, leaving a messy trail of snot and tears across the white fabric. “Oh, th-that’s a relief. Listen, I want to apologize for- “
“Time for my last-ditch secret technique!” the painted Magearna interrupted. Reaching an arm behind her, Duchess flipped the switch on her back from “Regular” to “Wumbo”.She smirked. “Try this on for size!” She wiggled her eyebrows as she emphasized that last word. With little fanfare, Duchess rapidly grew several stories tall, suddenly towering over the lab in a matter of seconds.
Angelys let out a surprised squeak. A stream of pee ran down the Lopunny’s leg as her already full diaper started to leak.
“What in the - ?” The professor quickly forgot what she had been crying about as she beheld this new development. “How did you do that without - “
Duchess interrupted the woman again. “You’re never gonna hurt Anjou ever again!” she boomed. Turning around, the gigantic fairy Pokemon positioned the very full seat of her diapered butt over the lab.
Pearwood held up her hands. “Wait, no, I’m not fighting anymore! Don’t - “
"Oh FUCK!" Angelys yelled out.
The Dynamax(?) Magearna sat down hard, crushing the professor, Angelys, and the lab beneath her colossal poopy diaper with a loud squish that could be heard for miles.
“Yeah, gotcha!” Duchess gloated, sticking her tongue out. "Who's the winner now?"
