Zapdos

Zapdos has an excellent typing, both offensively and defensively, which boasts resistances and immunities to the most common attacks of top-tier OU threats such as Jirachi, Metagross, Lucario, and Flygon. The Electric type is phenomenal offensively, as it lets Zapdos hit the majority of the metagame with neutral damage. Although Zapdos's Stealth Rock weakness limits its walling capabilities, Roost and Rapid Spin support help combat that problem. Zapdos is capable of taking on many of the OU tier's top physical and special threats thanks to its all-around great stats and typing. Its high Special Attack and good Speed allow it to perform wonderfully in an offensive role, and it has great coverage options in Heat Wave, Hidden Power Ice, and Hidden Power Grass. It can also use U-turn to function as a fantastic pivot, taking advantage of its defensive capabilities to open up safe switches for its teammates. Unfortunately, Zapdos struggles with the ever-popular Tyranitar, Nidoqueen, Latias, and Clefable, four of the strongest defensive options in the tier, although this can be remedied with proper team support. Zapdos is one of the most difficult Pokemon to counter in OU overall, as its generous movepool and great assets are near unparalleled on paper.
