Concept: The villain keeps having their secret lair destroyed by the hero, and they keep having to make new ones. After the hero crashes into and destroys their fifth lair in the past three months, the villain bursts into tears.
“Do you know how much effort I put into these lairs!? They’re so expensive! I’ve had to take out so many loans to repair all the damage you’ve caused! I’m in so much debt!” the villain cries as they mourn the roof currently crumbling.
“Oh, shit. Uh, sorry. Ha, I guess I thought you guys like… magically conjured these things? Or something? Sorry, I’ll just…” the hero continues to repair the damage done by them, then promises the villain that fights will stay outside from now on.
