I beat it with my Gyrados. It was pretty strong, like at 47, and he had Thunder, Blizzard, Hydro Pump, and Surf. Also, you might need Max Revives, or Revives and Super Potions in case he dies. I beat him first try.

Yes, you have to beat the Elite Four Champion before you can get Mewtwo, because there is a man standing outside the cave in Cerulean City, blocking the entrance, and he will only disappear if you beat the Elite Four Champion. Since Mewtwo is in the cave in Cerulean City, you have to beat the Elite Four Champion to even get into the cave where Mewtwo resides.
