Back in 2019, a YouTuber named Game Champ 2000 (
@Gamechamp3k ) decided to attempt one of the most insane Pokémon challenges ever created. He was going to beat Pokémon Blue on original Game Boy hardware without taking a single point of damage the entire game.
But here's where it got brutal: he set one rule for himself. If any of his Pokémon took even one HP of damage at any point, the entire save file had to be permanently deleted. No soft resets allowed and no backups whatsoever. Even getting poisoned or confused counted as an instant loss.
Pokémon Blue is basically rigged against you. That's because every move in the game with 100% accuracy still has a hidden 1 in 256 chance to miss. This means that a random freak miss from the AI could erase weeks of progress in seconds.
So Game Champ spent hours grinding battles against Metapod with Harden, biking back and forth to abuse the daycare for free levels, and manipulating the dumb Gen 1 AI into picking moves that physically couldn't hit him.
But the Elite Four was the real nightmare because you fight all five trainers back to back with no Pokémon Centre between rounds. One critical hit from Lance's Dragonite ends everything.
After 222 hours of grinding across 12 straight days, Game Champ finally beat the champion with total damage taken across the entire game being zero, marking the first time anyone had ever done it in history.
What a feat.
