Brock. Hate him - when I first played the original Pokemon, I chose what I considered to be the cutest Pokemon - Charmander. Lucky me - I had to choose the ONLY starter that wasn't very effective against his Onix.

Of course, Pokemon Yellow players shared the pain - Pikachu is also useless against Rock.

Had to backtrack, catch a caterpie, and level it up to Butterfree to finally bushwhack the first gym.
