Before starting, I want to say only one thing. As you can see in my nickname, I´m from Spain, so writing in English is very difficult for me. I´m sorry if the text has a lot of grammar/vocabulary mistakes.

<p>Like its older sibling Snorlax in OU, Munchlax can run an effective Curse set effectively in LC, with the distinction of possesing something like a recovery move, the Oran Berry-Recycle combination. After using Curse and recovering lost HP with Oran Berry, Recycle allows Munchlax to regain the Oran Berry. This means that Munchlax can recover 64.52% of its HP by using 2 Oran Berries.</p>
<p>76 HP EVs allow Munchlax to reach 31 HP. This HP number is the maximum you can have while still losing only 1 HP under Hail or Sandstorm. If Munchlax had 32 HP or more, it would lose 2 HP per turn under those weather conditions. A Sassy nature and 236 EVs maximize Special Defense, and the last 196 EVs are placed into Defense.</p>
<p>On the offensive side, Return is a very powerful STAB move, but Body Slam can be used for paralysis support. Fire Punch allows Munchlax to hit Steel-types for super effective damage, while putting the hurt on Ghost-types. ThunderPunch can be used instead of Fire Punch, as it allows Munchlax to hit Rock-types for neutral damage and pesky Water-types (bar Chinchou) for super effective damage. Earthquake allows Munchlax to hit Rock- and Steel-types for super effective damage, but Flying or Levitating Ghosts such as Drifloon and Gastly will be immune to both offensive attacks.</p>

<p>Munchlax can also use a mono-attacker set by changing the fourth attack to Rest and the Oran Berry to Chesto Berry. This will allow Munchlax to restore its condition and all of its HP in a single turn, wake up instantly thanks to the Chesto Berry, and then recover the Berry with Recycle to start the healing cycle over. It's one turn faster than using Rest without recovering the Berry (without Recycle: Rest + 2 turns Munchlax is asleep = 3 turns; with Recycle: Rest (Munchlax wakes up due to Chesto Berry) + Recycle (to recover the Berry) = 2 turns).</p>
<p>If you are looking for perfect coverage, a more specially-oriented set could be used, with a Quiet nature and an EV spread of 76 HP / 196 Def / 36 SpA / 156 SpD, and Surf in the last moveslot. 36 SpA allows Munchlax to always OHKO 36 HP / 36 SpD Jolly Aron after three layers of Spikes and Stealth Rock; even with only one layer and without SR there is a small chance that it will OHKO. Stockpile is an option to use over Curse on the more specially-oriented set due to the loss of Special Defense investment.</p>
<p>Gligar is a fantastic partner to use alongside Munchlax, due to his high Defense, Rock and Fighting resistances, and the ability to KO them with Earthquake / Aerial Ace (Steel-types are also taken care of with Earthquake). Nasty Plot Croagunk is one of the best teammates for the mono-attacker set, as he resists Fighting-type attacks, and can use Vacuum Wave to demolish Rock- and Steel-types, while Ghost-types are bested by Dark Pulse. For the mixedet, Pineco is the best partner, because he can set up Spikes and Stealth Rock, boasts a resistance to Fighting-type attacks, has access to Explosion, and can use Earthquake to hit Rock- and Steel-types for super effective damage. Finally, due to the Curse Speed drop and Munchlax's naturally low base Speed stat, Trick Room support can be a good option. Bronzor can provide Trick Room support, resists Rock- and Steel-type attacks, and can use Psychic to KO Fighting-types.</p>
