ITT Pokemon that became bros by shear coincidence.

I was playing mystery dungeon explorers of sky and got my first ever egg reward. Lo and behold it hatched into a shroomish knowing wake-up slap. It's ability was effect spore so whenever it'd get hit, it'd inflict a status ailment on an enemy, and sleep powder + wake up slap ruined everything in the game. Later on it learned spore and became even godlier, and once I evolved him and taught his focus punch, the rest of the game just didn't seem fair.

I loved this guy so much that I made a copy of him for heart gold, knowing spore, focus punch, substitute, and seed bomb. Holding a poison orb with the ability poison heal. My nigga still wrecks shit in BW
