Zapdos

Unlike other Electric-types, such as Tapu Koko and Thundurus-T, Zapdos has the ability to run defensive sets to take on dangerous attackers, including Mega Salamence, Mega Gyarados, and Mega Lucario. Zapdos is one of the few Electric-types with access to reliable recovery in the form of Roost, which helps it stay healthy and perform its defensive role. In addition, Zapdos has a unique niche with its access to Heat Wave, allowing it to threaten Steel-types, particularly Mega Scizor and Ferrothorn, making it a good fit in a variety of team archetypes.

However, Zapdos's defensive capability is sometimes hindered by Stealth Rock; furthermore, Zapdos's defensive stats are not stellar, so it is reliant on its typing to effectively function as a wall.
