I got a blaze cyndaquil today but I want to breed one with flash fire. Is it possible for me to breed with some other Pokemon so that the offspring is a cyndaquil with its hidden ability?
You can only get a Hidden Ability Cyndaquil if it already has Flash Fire as its ability. If none of the parents have their ability the offspring will NOT have the hidden ability, only its regular ability. If the Cyndaquil is male and has Flash Fire then breed it with a Ditto and the offspring will have a chance to have Flash Fire. If the Cyndaquil is female and has Flash Fire, you can breed it with a Ditto or another Male Pokemon in its Egg Group and the offspring will have a higher chance to have Flash Fire.
