Serperior is a solid Pokemon in NU for a few reasons. Thanks to its high Speed, Serperior can outpace and check common threats such as Jynx, Scolipede, Charizard, Tauros, and Primeape, and its well-rounded stats and decent movepool allow it to function as an effective attacker and supporter. Serperior's great Speed gives it the opportunity to set up before the opponent can stop it. Unfortunately, with below-average offensive stats and low Base Power attacks, Serperior is typically forced to boost its stats in order to sweep teams. While it has a good support movepool, Serperior's offensive coverage options leave it walled by many common defensive Pokemon, such as Audino and Metang.

Name Item Nature

Calm Mind

Life Orb Timid
Moveset EVs
~ Calm Mind
~ Taunt / Substitute
~ Giga Drain
~ Hidden Power Rock
4 Def / 252 SpA / 252 Spe

Serperior's high base Speed makes it a viable Calm Mind user, giving it the ability to boost its Special Attack to clean up later in the game. Taunt is used to keep Serperior from becoming setup fodder, prevent entry hazards from being set, and keep the opponents from statusing or phazing it, making Serperior a team player as well. Substitute, on the other hand, can be used to help Serperior get to Overgrow range or to keep it from being taken out by faster opponents, but without Taunt, Serperior struggles against other Calm Mind users such as Musharna. Giga Drain is the best STAB option for Serperior, as it provides a way to recover health. Finally, Hidden Power Rock is used for coverage to hit the Fire-, Bug-, and Flying-type Pokemon, such as Charizard, Scolipede, and Mandibuzz, that would wall Serperior otherwise.

Dual Screens

Light Clay Timid
Moveset EVs
~ Reflect
~ Light Screen
~ Taunt
~ Giga Drain
252 HP / 4 Def / 252 Spe

Serperior's high Speed, great bulk, and access to Taunt make it a good dual screens user. This particular set faces competition with Gardevoir, which has access to Memento, but Serperior's greater Speed gives it an easier time setting up Reflect and Light Screen. Taunt is used to protect Serperior and its partners from status and phazing, while also preventing Stealth Rock from being set up by common leads and preventing opponents from trying to set up alongside Serperior. Finally, Giga Drain is a filler move which gets STAB and can help Serperior recover some health.

Other Options

Despite its poor coverage options, Serperior still has some good support moves up its leaves. Access to Leech Seed, Glare, Safeguard, and Dragon Tail might give you the impression that Serperior can pull out a good support set, but such a set would be outclassed by Roselia, Vileplume, and Tangela, as they have better support movepools, bulk, and abilities. Aromatherapy is a great support move that most other Grass-types can't fit on their sets, but it is only legal on Serperior with a Hardy nature, making it completely worthless. Serperior also has access to some other offensive options, such as Sword Dance, Coil, Aqua Tail, and Dragon Tail, but Serperior has awful coverage options on the physical side. Finally, Leaf Storm could be used with a Life Orb to OHKO Piloswine, but Serperior needs Calm Mind to work decently and sweep late-game.

Checks and Counters

Although Serperior is bulky and fast, it can be easily walled by many Pokemon. Sap Sipper Miltank and Sawsbuck both hard wall Serperior and receive an Attack boost if it tries to use Giga Drain against them. Steel-types and Poison-types also take on Serperior well, as they resists its STAB while taking very little from its most common coverage moves. Muk can check both sets, as it has Brick Break to take out Reflect and Light Screen set by Serperior, rendering it useless. Toxic Spikes greatly hinder Serperior, keeping it from staying healthy with Giga Drain. Liepard and Volbeat can Encore or Taunt Serperior with the help of Prankster. Bastiodon and Zweilous can easily take a hit and phaze Serperior out to weaken it with entry hazards. Finally, fast Pokemon such as Swellow or fast Choice Scarf users such as Jynx, Primeape, Braviary, Rotom-A, and Charizard can easily outspeed Serperior and OHKO it with the appropriate move, but keep in mind Serperior can play around with some of them by using Substitute.


Serperior's Dream World ability, Contrary, inverts stat changes, making stat drops become boosts and vice versa. Leaf Storm is the only move that Serperior receives that lowers his stats, but effectively receiving +2 on every use of Leaf Storm quickly adds up, making Serperior a dangerous sweeper.
