How do you determine if Aron/Larion/Aggron have its hidden ability "heavy metal" in x/y?

Question

I have Pokemon Y and I have been trading for Aron trying to get one with its hidden ability, the thing is I have no clue how to check if it has the ability, like some will pop up in battle, but his is just his weight... will that show up on the battle screen or is there another way to check this.

Answer 1

The easiest way to check your Pokemon's Ability is to view its summary, which shows every detail about your Pokemon. Including its Ability.

Hit the X button and select "Pokemon". You'll get a list of your Pokemon. Tap your Aggron/Lairon/Aron and tap "Summary". On top of your screen, your Pokemon's ability will be displayed along with all its stats and various other details.
