Stats: 160 / 130 (+20) / 125 (+60) / 65 / 130 (+20) / 30
Types: /
Ability: Natural Cure
New Moves: Wood Hammer, Play Rough, Mirror Coat
Competitive Description: A very bulky and strong physical attacker! Snorlax can be one of the most threatening Pokemon due to its high bulk and attack stats paired with Curse, amazing coverage moves and access to get rid of status such as Toxic and Paralysis with Natural Cure. Wood Hammer is a stronger STAB move that deals massive damage, but however has recoil so if Snorlax is running Wood Hammer, it is necessary to run Rest, as that is Snorlax's best recovery move. Play Rough is used to fit Snorlax's tree and grass design, which represents nature and beauty, and is also a strong coverage move. Finally, Mirror Coat can be used with it's high special bulk to revenge kill special attackers. Snorlax can clean many teams when given the chance. Cons? Snorlax has a bunch of weaknesses that can keep it busy while battling, and is slow. However, Trick Room can be used to make Snorlax faster, and due to Snorlax's great bulk, it can take a few hits from its weaknesses depending on the Pokemon.
