When a Pokemon with this Ability is hit by a move that makes contact, the Ability of the attacking Pokemon will become Mummy. Besides spreading Mummy in battle, the Ability does not have any other effect.
If a Pokemon with Rock Head uses a recoil contact move on a Pokemon with Mummy, the Pokemon will take recoil damage. If a Pokemon with Parental Bond uses a contact move on a Pokemon with Mummy, the Pokemon’s Ability will be changed, then it will continue to hit a second time.
Multitype, Stance Change, and Mummy itself are not affected by Mummy.
Outside of battle
Mummy has no effect outside of battle.
