I feel like every thing Chalmers says about Aurora Borealis should've gotten a hit on Skinner until he says "May I see it?" which would drop Chalmers to 0.
Well Seymour, I made it. Despite your directions. Ah, Champion Chalmers, come in! I hope you're prepared for an unforgettable battle! Hmmm. Rotom used Overheat! Oh ye gods! My Rawst is ruined! But what if... I were to purchase fast food and disguise it as my own cooking? Quite the Foul Play, Skinner! Why is there smoke coming out of your oven, Seymour? Oh! That isn't smoke. It's steam! Steam from the scalded clamperl we're having. Mmm! Scalded clamperl! Chalmers used Mean Look! Chalmers used Parting Shot! Got away safely! Skinner used Bestow! Champion, I hope you're ready for mouthwatering hamburgers. I thought we were having scalded clamperl. No, I said scalded tepig! That's what I call hamburgers. You call hamburgers scalded tepig. Yes! It's a regional dialect. Hm. What region? Upstate Castelia? Really. Well I'm from Gym Street and I've never heard the phrase scalded tepigs. Oh no, not on Gym Steet, it's a Mode Street expression. I see. Chalmers used Bite! You know, these hamburgers are awfully similar to the ones they have at Pokémon Centers. Oh ho ho, no, patented SkinnerBurgers! Old family recipe. For scalded tepigs. Yes! Yes, and you call them scalded tepigs despite the fact that they are obviously heat crashed. Skinner used Amnesia! Excuse me for one second. Oven used Inferno! Skinner used Yawn! Well, good time was had by all, I'm pooped. Yes, I should be-good lord, what is happening in there? Aurora Beam? A-Aurora Beam?! At this time of year, at this time of day, in this part of the region, localized entirely within your kitchen? Yes! May I see it? Skinner used Quash! No. Seymour! The house is on fire! No, mother, it's just an Aurora Veil. Well Seymour, you are an odd trainer, but I must say, you scald a good tepig.
Possibly Chalmers has 0 ATk EV's and a -Atk nature. And Skinner benefits from Eviolite and has 252+ DEF. -because Skinner evolves into Chalmers at level 52-
This should really have had Seymour's health go down as Chalmers said "At this time of year" and so on until he gopt down to 1 hp, to then one shot kill Chalmers by saying "no"
I fucking pissed myself laughing at how Skinner's health bar went down with each excuse, and then died of laughter when the "you're low on health" sound started to play. It was fucking perfect.
