Which was the hardest Kanto gym leader for you. Give reasons also.
For me, it was Misty. When I first time played LeafGreen or first time played any pokemon game, I chose Charmander. Then, I did not know any basics of pokemon.My team was consisting of lvl 31 charmeleon and other pokemons in 10s. Misty keep Water Pulsing Charmeleon and he always die in 2 hits. It took 20 tries to get a lucky critical hit.
