I caught them all using Pokéballs, but it took at least 40 each, but I did it because I saw it as a cool challenge that I was doing with my brother. Mewtwo really ticked me off! That Pokémon was nearly impossible to catch! I got it down to 1 health with false swipe and put it to sleep, yet it seemed impossible to catch and Mewtwo eventually ran out of PP for it's move and used struggle. It has the same catch rate of the legendary trio, yet it was way harder. It took me about 58 soft-resets to cram that purple, life sucker into a Pokéball! As soon as I caught it I collapse in exhaustion...and then my little brother reset my game...(implodes).
