Best Wishes Do Come True Under The Sun & Moon
I think it would be cool if Ash caught Malamar if it were possible, then he'd have to try and get it under control kinda like Charizard and Pikachu except those weren't pure evil. It would be interesting seeing how careful he'd have to be too. Malamar should be stronger than all of the current cast combined so he'd really be pressing his luck when he even thinks of sending it out, but he also couldn't just leave it in the Poke Ball.
