Her shorts come off

She sends back Pawmot and brings out her Bellibolt. At least this one has some bulk to it. The giant frog-like thing comes rushing out with a smile on it's face unaware of the insta-humiliation it and its trainer is about to receive in due time.

Her Bellibolt somehow lives a maxed out Outrage which leaves everyone jaw-dropped, Iono included. Iono then realizes this isn't quite as good as she hoped, since dragon is resistant to electric which is what this thing's good at but any damage is better than none.

"Bellibolt, use Thunderbolt!" She shouts at the top of her lungs as she doesn't think she'll be saying those words for awhile. It lands the thunderbolt but predictably, it does scratch damage to Baxcalibur leaving it out cold. At least the Baxcalibur is confused now so she's got that to hope for, but then she realized, self-inflicted confusion never seems to make the user hit themselves, it's rarer than a one-hit KO move hitting. She's fucking doomed. And thus her Bellibolt goes down from yet another Outrage.

"I'm sure you can figure out what to take off at this point." Florian mocks. Iono can, whether she likes it or not, but due to the bet she has to live by it and takes off her shorts revealing her yellow and black polka-dot panties. Also predictably, there's uproarious applause everywhere.
