I was battling and my Chatizard was hit by poison powder, defeated the pokemon and my Charizard got rid from the poison. I didn’t pay atention to the message but I saw a couple of hearts over his head in the animation. As far as I know there are no habilities in this game and I can’t find anywhere why this happened.
Thank you in advance and sorry if I misspelled something, english is not my main language.
