Snorlax

Snorlax's excellent Special Defense and a lone weakness to Fighting make it difficult to KO without relying on dedicated Fighting-types. This allows Snorlax to blanket check a number of dangerous threats, such as Tapu Lele, Naganadel, Greninja, and Volcarona. On top of this, Snorlax can utilize Gluttony, a pinch Berry, and Recycle to give itself an access to consistent recovery, which further improves its defensive capabilities. These factors can make Snorlax a problematic Pokemon to deal with, especially for teams that lack a way to immediately threaten it. However, Snorlax can struggle with physical attackers due to a low Defense stat and a lack of resistances. This means setting up Curse can be somewhat difficult with the prevalence of powerful physical attackers. Abysmal Speed can also be a detrimental factor for Snorlax, as it will be vulnerable to status moves, particularly Taunt.
