I'm literally just putting this here for completion sake but uh, it's pretty bad. It has a good story though.
Many years ago a child was playing a fresh new save file on their brand-new pokemon blue. They'd named themselves "Zy-lock" because they thought it sounded cool and had just gotten to Cinnibar. Now little-kid me wasn't supposed to be playing this game in class, but they were so close to missingno, and there's something so exciting about that first missingno encounter on a fresh save, you know?
So they did the glitch, patiently surfing up and down the coast, waiting for the glitch-fairy to sprinkle some magic poke-dust on their inventory and gift them the magic of infinite rare candies. Only that did not happen! Instead of their familiar missingno, a trainer appeared, a trainer with a name unlike any other trainer in the game, "Chief."
And then he unleashed it and suddenly the familiar battle music was gone. In it's place was some sort of fast-paced insanity unlike anything the smol child had ever heard. Terrified for their soul, they shut the game off, blushed, and prayed the teacher did not know, the sins they had committed.
It was a long long time before they were brave enough to ever try it again.
