Did you all caught D. Metang in the Murk Forest? Mine killed itself. It literally took 30+mins and it struggled then it died. I used all kinds of pokeballs from ultra balls, timer balls, and level balls. It was at 1hp but I forgot to bring status-inducing pokemon. Sadly I forgot where was the last time I saved so I can’t go back.
Delta Metang, and Metang in general, have the absurdly low catch rate of 3 (the same as mewtwo, ho oh, etc)
I didn’t catch it either, I had to trade for it.
Throw a delta ball.
quick ball spam
if you dont catch it sr and try again lol
