Shuckle

Shuckle is a Pokemon of extremes. Its ridiculously high Defense and Special Defense stats are coupled with other stats that are ridiculously low, which makes it extremely difficult for it to inflict meaningful damage through conventional means. Shuckle's resistance to Normal in combination with its lack of weaknesses to common types, such as Electric, Ground, and Fire, makes it one of the most reliable Snorlax checks in the game. It is unique in that it has high Special Defense alongside its resistance to Normal, meaning it can wall many common Explosion users, such as Gengar and Exeggutor. Its downfalls are its bare movepool and awful attacking stats, which limit its options to spreading poison with Toxic and PP stalling and make it one of the most passive Pokemon in the game.
