Regirock

Regirock sits in a decent place within the NU metagame, boasting the most physical bulk and checking many of NU's top-tier physical threats, such as Swellow, Kangaskhan, and Braviary, with its mono-Rock typing. Furthermore, it is equipped with a great Attack stat, making it an effective, hard-hitting tank. Along with its access to a variety of support options, Regirock is undeniably a tough threat to take down without strong super effective STAB attacks. However, Regirock does come with evident flaws, most notably its lack of reliable recovery. This makes it vulnerable to wear and tear, eventually succumbing to the damage it's meant to be taking. On top of that, the same Rock typing that makes Regirock a great answer to the sweepers mentioned above leaves it with weaknesses to common Water-, Grass-, Ground-, and Fighting-type attacks. Due to this, many powerful attackers, such as Samurott, Exeggutor, Golurk, and Sawk, can greatly hinder Regirock's performance.
