With a stat spread that makes the Los Angeles Clippers look competent, and a movepool about as shallow as Brad Pitt's personality, you would think that Serperior would be doomed in the powerhouse filled DW OU. You would be so wrong. Its ability, Contrary, reverses its stat changes. Combine this with Leaf Storm, and you have yourself a Pokemon that can pose a threat with mono-type coverage, and Grass mono-type coverage notwithstanding. It also has decent Speed as well, so don't think you can just pounce on it after it attacks either.
Base Stats:
HP: 75
Atk: 75
Def: 90
SpA: 75
SpD: 90
Spe: 113
Leaf Storm, Leaf Storm, Leaf Storm. You may as well carry that as your only move, because in many games, that's all you click. In all seriousness though, Serperior doesn't need much offense besides Leaf Storm, and can run various deadly sets.
Serperior @ Leftovers
Trait: Contrary
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature (+Spe, -Atk)
- Substitute
- Leech Seed / Glare
- Leaf Storm
- Hidden Power Fire / Hidden Power Ice / Hidden Power Ground / Hidden Power Rock / Dragon Tail
This is that set that has made Serperior an infamous assasin in DW OU. Contrary Leaf Storm, of course, is one of the most fearsome Attacks in the tier. Unless a Pokemon has a x4 resistance to it, they're bound to take hefty damage. Those that can take a Leaf Storm could potentially be overwhelmed by SubSeed spam, while others are crippled by Glare. Sadly, Serperior's boons end there, as its pathetic movepool means it can only use a Hidden Power for coverage or Dragon Tail to get out of a corner.
Serperior @ Choice Scarf / Choice Specs
Trait: Contrary
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature (+Spe, -Atk)
- Leaf Storm
- Giga Drain
- Hidden Power Fire / Hidden Power Ice / Hidden Power Ground / Hidden Power Rock
- Toxic / Glare
Now, what's the only thing scarier than a +6 Leaf Storm from Serperior? A Specs boosted +6 Leaf Storm or a +1 Speed +6 Leaf Storm from Serperior! Of course, that's about all this set has to offer, because all it has after that are horrendously weak Giga Drain and Hidden Powers. The fact that it must run a support move in the last slot just shows how sad Serperior is.
Serperior @ Life Orb
Trait: Contrary
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature (+Spe, -Atk)
- Leaf Storm
- Hidden Power Fire / Hidden Power Ice / Hidden Power Ground / Hidden Power Rock
- Giga Drain
- Taunt / Substitute
Offensive Serperior, see Subseed set, except it now uses more Attacks. Move along, nothing to see here.
Serperior @ Light Clay
Trait: Contrary
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature (+Spe, -Atk)
- Reflect
- Light Screen
- Taunt
- Leaf Storm
A pretty lame use of Serperior. Blahblah Dual Screens+Taunt to support the team. Sadly, Serperior's movepool is so shallow that you actually don't miss out on much coverage... Still, this is generally a misuse of Serperior and should only be used if you want a back-up screener.
Counters:
Heatran: Can obviously wall all non HP Ground Serperior and destroy them with a Fire STAB. However, beware of the Subseed set, which can actually overwhelm Heatran if the user is not careful
Scizor: A x4 Grass resist is pretty much a must if you want a Pokemon to check Serperior. Scizor is one of these Pokemon, although Hidden Power Fire is just annoying. Scizor can screw over Serperior pretty badly with Bullet Punch or U-turn as well, so as long as that green snake doesn't carry you know what, you should be fine.
Genesect: see Scizor
Dragonite: Can tank any one of Serperior's Attacks thanks to Multi Scale, although do be aware that a +2 HP Ice will KO if Multi Scale is not active. Dragonite can use this opportunity to either set up and go on a sweep of its own, or go for the outright KO.
Salamence: see Dragonite without Multi Scale
Volcarona: Pretty much the same dealeo as the guys before it. x4 Grass resist, can either threaten Serperior with a powerful STAB or set up Quiver Dances. Stealth Rock is freaking gay though, and Offensive versions of Volcarona can be overwhelmed by Subseed if not careful.
