Zapdos

Zapdos is a great defensive check to several threats thanks to a few traits. The first is reliable recovery in the form of Roost, allowing it to stay healthy throughout the match, unlike many other Electric-types. The second is its solid bulk, which, coupled with a good defensive typing, allows Zapdos to check some of the tier's most dangerous threats, such as Mega Pinsir, Mega Scizor, and Tornadus-T. The third is its ability to pressure offensive teams with the combination of its decent power, rather good coverage, and Roost stalling. Finally, Zapdos has access to Defog and the ability to beat Bisharp, something no other Defogger can do besides Mandibuzz. Unfortunately, Zapdos is held back by a Stealth Rock weakness, which is an especially large issue for a Defog user, and does not have the sheer bulk that some other defensive Pokemon possess. Furthermore, the Thundurus formes, both of which boast much more useful offensive abilities and Nasty Plot to help muscle through walls, outclass Zapdos offensively. When using Zapdos, be mindful of its limitations and play to its strengths, and it will be very effective.
