Overview

Mothim is one of the Bug / Flying type Pokemon that has been made viable with the addition of Quiver Dance to his movepool. Mothim was overlooked last generation because of his mediocre stats; while his offensive stats are good, Mothim's middling Speed stat held him back, but now he has a move to remedy this flaw with. Mothim's movepool is also pretty shallow, but he gets the coverage he needs with only Bug Buzz, Air Slash, and Hidden Power thanks to the other new toy he got in BW: Tinted Lens. Tinted Lens doubles the power of all resisted moves, which means Mothim hits the majority of the tier hard with a powerful Bug Buzz, even if it's resisted. Mothim's typing is both a blessing as well as a curse; he has a nice 4x resistance to both Grass- and Fighting-type moves, as well as a 2x resistances to Bug-type moves, but Mothim has a crippling 4x weakness to Stealth Rock and Rock-type moves as well as a 2x weakness to the common Fire-, Ice-, Electric-, and Flying-type moves. Mothim also faces competition from Butterfree and Masquerain who got Quiver Dance as well; however, Mothim has qualities over both of them. Mothim has Tinted Lens and a higher Speed stat over Masquerain, Air Slash over Butterfree, and a much higher Special Attack stat over both Butterfree and Masquerain, making it a prime choice over the two if you prefer power over a sleep inducing move or Baton Pass + Intimidate.

This is the best Mothim can do, and the only thing he should really be doing. Quiver Dance will patch up Mothim's middling Speed, reaching a good number with only one boost, while also increasing his already good Special Attack. Bug Buzz is the most powerful move at Mothim's disposal and will hit the majority of the tier hard after a boost or two, coupled with Tinted Lens. Air Slash is a great secondary STAB move, backing up Bug Buzz. The final move depends on what you prefer. Substitute will ease setting up, and is the preferred choice. Substitute protects Mothim from status as well, something that will otherwise severely hinder his capabilities. However, Hidden Power Water or Hidden Power Ice can be used as well. Hidden Power Water will make short work of Camerupt, while Altaria can't withstand a Hidden Power Ice; both of them are hard for Mothim to take down with only Bug Buzz due to their specially defensive capabilities and powerful moves, and Hidden Power will ensure a OHKO on both of them. Hidden Power Ice will also do more damage to Golbat than either Bug Buzz and Air Slash.

Other Options

Mothim's other options are pretty scarce, especially with Tinted Lens limiting them. Giga Drain and Roost can be used to restore Mothim's HP, but the two moves can only be used with Swarm and the loss of Tinted Lens is not worth it. Silver Wind and Ominous Wind are both rather gimmicky options over Bug Buzz and Shadow Ball, respectively, but can raise Mothim's stats by one stage each. However, Mothim does need the power behind Bug Buzz, so it's not very wise to use Silver Wind over it; using these two moves alongside Bug Buzz, however, can prove useful on rare occasions. Signal Beam is also an option over Bug Buzz, being able to confuse the opponent, but the loss of power can be noticeable at times. Tailwind grants Mothim's team with a Speed boost for four turns, while Toxic can be used to break down certain Pokemon. It should be noted, however, as with Giga Drain and Roost, that Ominous Wind, Tailwind, and Signal Beam are illegal with Tinted Lens, making them even less viable. Choice Scarf and Choice Specs are also decent options, especially with Tinted Lens, but Quiver Dance is always the superior way to go with Mothim. He does have U-turn to abuse these two items with. Mothim also has an Attack stat equal to his Special Attack, but he has no strong physical moves at his disposal. The aforementioned U-turn, as well as Bug Bite, Aerial Ace, Acrobatics, and Return is all Mothim has, and the only way to increase Mothim's Attack stat is with the psuedo-Swords Dance combination of Psych Up and Swagger.

Checks and Counters

Tinted Lens makes it harder for certain Pokemon to switch in on Mothim, but it's far from impossible to beat him. Golbat has no problem switching in on unboosted attacks, while being able to easily break through Mothim with Brave Bird and Toxic. Golbat even has Whirlwind to phaze Mothim out, but it needs to be careful of a highly boosted Psychic or Hidden Power Ice. Rotom-S can survive a +1 Bug Buzz from Mothim, and proceed to KO him with Thunderbolt at +1 Special Defense if Mothim has suffered prior damage. Rotom-S will always outspeed Mothim at +1 Speed with Choice Scarf. Sturdy Golem, Gigalith, and Lairon can come in when a teammate has fainted or when Mothim is setting up, survive a hit, and proceed to OHKO Mothim with their Rock-type moves. Finally, Lickilicky and Regice are hard for Mothim to take down without multiple boosts, due to their high Special Defense stats.
