She loses the battle, and is now fully naked

"I mean at this point you could just forfeit." Florian suggests.

"That's not allowed of me as a gym leader, friendo." Iono rebuttals.

"And public nudity is?"

"Never said it was either, but forfeiting is a guarantee firing if you're in a position like me." Iono answers throwing out her final Pokemon, a Mismagius. If this were Florian's first gym, he'd be wondering why the hell she's even using one of these since it's not an electric type, though since all of the gyms leaders, except Larry technically, do this exact thing, he saw something like this coming. Good thing he immediately thought to not use his ground type though.

"Actually come to think of it, you can't risk it or something considering you also stream?" Florian calls a brief timeout.

"I probably could but I wanna combine the best of both worlds you know? Being a gym leader that streams is pretty unique dontcha think friendo?" Iono forces a smile.

"Well I guess it is pretty unique, but that won't matter too much after this is over!" Florian gets serious again and calls for yet another Outrage before Iono could even terastalize her Mismagius. And thus the crowd goes wild along with a smug Florian and beyond pissed off Iono as she is taking off her panties in defeat and rage. So much rage, she'd make Hydreigon look calm in comparison.

"Here's your stupid badge!!!!!" Iono screams as she throws the badge right at Florian. She starts running home only to realize that she should go and grab her clothes first. After running back she finds they disappeared. "What the fuck!?!?!?!?" she screams.
