Gengar is my favorite pokemon and i want to use him competitively and i want to know if he can have the prankster ability? If so does anyone have one they can breed for me?
Gengar only has levitate. You don't breed for abilities since said Pokemon automatically comes with one. You can only breed for egg moves or secondary and hidden abilities. To get hidden abilities you need to catch the Pokemon with that ability in the same species then breed it. Check out Serebii to know the various abilities each Pokemon has.
