Zapdos

Zapdos has an uncommon niche in 1v1 as a hybrid of offense and stall, giving it a unique matchup spread that can't easily be achieved using exclusively one or the other. Gigavolt Havoc can OHKO the many bulky Water-types in 1v1, such as Primarina, Tapu Fini, Mega Slowbro, and Mega Gyarados, while slower, bulkier Pokemon such as Necrozma and Porygon2 get Toxic stalled. Zapdos's nature as a hybrid Pokemon adds a degree of unpredictability that makes it difficult to play against. Pressure is a useful ability that lets Zapdos PP stall Pokemon that rely on a single move, such as Magearna. However, Zapdos is held back by its mediocre bulk, necessitating a very defensive spread that can't afford to invest in Speed. Zapdos's average bulk and inability to invest in Speed keep it from reliably tanking hits from powerhouses like Mega Charizard Y and Substitute Torrent Greninja or outspeeding threats such as Tapu Lele and Jumpluff. Zapdos's lack of access to Taunt means that it is outclassed as a staller by Pokemon that can use it, such as Deoxys-S, and it cannot win against other stallers such as Whimsicott and Registeel.
