Snorlax

On the surface, Snorlax looks good in DPP OU. Snorlax's huge special bulk and access to Pursuit give it a niche as a special tank. With a Lum Berry, it notably can switch in on any move Gengar or Choice-locked Rotom-A can use and Pursuit trap it or remove it with Crunch, something neither Tyranitar nor Scizor nor Weavile can do. In addition, its natural bulk and Thick Fat let it check the many powerful special attackers in the tier despite its lack of resistances, such as Latias, Heatran, Starmie, Suicune, Empoleon, and Zapdos. Snorlax also has access to the strongest move in the game with a STAB-boosted Self-Destruct, which KOes anything that doesn't resist or is immune to it, as well as putting a huge dent in even bulky Steel-types such as physically defensive Skarmory at +1. Self-Destruct, the potential for paralysis with Body Slam, and its bulk also allow Snorlax to soft check physical sweepers that lack strong Fighting-type coverage such as Dragon Dance Gyarados. In addition, Snorlax has niche usage as a wincon as a Curse sweeper with Rest, as some defensive teams can struggle against it when it is the last Pokemon and can no longer be phazed.

Unfortunately, Snorlax suffers from many issues in DPP OU—primarily, Snorlax is extremely slow, is very vulnerable to residual damage, and struggles with common Fighting-types such as Breloom, Machamp, Infernape, and Lucario. Snorlax is the slowest Pokemon in DPP OU; it really struggles with offensive pressure from faster Pokemon, as even if it increases its Defense with Curse, it still takes a lot of damage from physical attackers such as Metagross, Scizor, Gyarados, Tyranitar, and Dragonite. Residual damage ruins Snorlax's ability to take hits, which is further exacerbated by Snorlax’s lack of reliable recovery. Stealth Rock, sand, and Spikes make it struggle to handle strong special attacks such as Choice Specs Latias's Draco Meteor and Life Orb Gengar's Focus Blast over the course of the game. These special attackers can further hurt Snorlax with Trick or Explosion. Snorlax also struggles to hold Leftovers, as all of Gengar, Heatran, and Rotom-A like to use Will-O-Wisp to neutralize any Snorlax without a Lum Berry or Rest. Snorlax further has to make important choices with its moves. Not only is Snorlax walled by almost all Steel-types and Tyranitar due to struggling to fit Earthquake, it also has to choose between using Self-Destruct and Pursuit, as they are illegal alongside each other. Snorlax also struggles to damage physically defensive Skarmory and RestTalk Rotom-A even with the correct coverage options, as they are bulky enough to survive boosted hits. Beyond all of this, Fighting-types easily outspeed and OHKO it. Breloom freely generates momentum on Snorlax that lack a Lum Berry with Spore, while Lucario can OHKO it through a Defense boost. These faults make Curse + Rest Snorlax a very rare sight in the tier, as supporting it requires far too many resources to be worth it. As such, while Snorlax can fit a few very aggressive teams as a one-time special tank, it generally isn't recommended for use in DPP OU.
