Fly to Cerulean City, then Surf southwest to Cerulean Cave.
There are some hidden items in the cave, and is home to the strongest wild Pokémon in the Region.
At the end of the Cave is Mewtwo @ Lv70. Bring a Pokémon with sleep and reducer to red HP bar, preferably Gengar and Raticate.
Once Asleep and ~5% HP, throw a Ball, and it's caught.
After exiting Cerulean Cave, I went to Celadon City to certify my Gen 1 Pokédex finally COMPLETE!
EVENTS OFF-SCREEN:
Grinded my party to Lv100, over and over at the League.
