I kept my Masterball. Didn't ever need to use it. Even that Mewtwo fell before a paltry Ultraball despite being at nearly full health. Fun!
Can you imagine how upset you would be if it didn't!holy_secret said:Did it work for him?theskadudeguy said:I have a whole bunch of them because I never liked using them, using them felt like such a waste so I traded them across games. The roaming ones were kinda worth it (Entie, Suicine, Riakou, Latios, Latias, Cressellia, Tornadus, Thunderus etc.)
Although I did once meet a guy who thought the whole purpose of the game was to exhaust an area of pokemon - a kinda literal Gotta catch em all. And progressed through the game but always heading back to to Veridian forest trying to catch EVERY pokemon in the area until no more would appear. I think he used the Masterball on a Weedle
