Mawile

Mawile is an overall average Pokemon that is able to serve as a wallbreaker or a physical wall. This versatility is thanks to its nice movepool, with decent offensive and utility moves such as Play Rough, Iron Head, and Stealth Rock, and two great abilities in Sheer Force and Intimidate. Furthermore, Mawile has a great offensive and defensive typing that offers good STAB coverage and a useful resistance to Stealth Rock and an immunity to Toxic Spikes. When serving as a wallbreaker, Mawile can break through many slower foes such as Drampa and Clefairy, and even certain faster ones such as Alolan Raichu thanks to Sucker Punch. As a physical wall, Mawile can take hits from many physical Normal-, Dark-, and Grass-types, including Stoutland and the physical variants of Skuntank, Spiritomb, and Shiftry, and either cripple them with Toxic or Knock Off or use the opportunity to set up Stealth Rock. Sadly, Mawile's stats are a large setback; though it has somewhat respectable Attack and Defense stats, Mawile is pretty slow and specially frail, making it relatively easy to KO for many offensive foes. These downsides furthermore leave it with a lot of competition in both of its potential roles, with other wallbreakers either offering a higher damage output and bulk, such as Aggron, or superior Speed, such as Skuntank and Stoutland, allowing them to threaten a larger number of Pokemon. Similarly, other physical walls such as Regirock and Metang can accomplish many of the same things Mawile can defensively, and even bring their own unique aspects in Regirock’s higher natural bulk and Metang’s access to Earthquake to punish switchins; both also have noticeably higher special bulk.
