The problem I find with Scolipede is that it is incredibly hard to stop it from doing its job: the worst part being it can fulfill so many roles. The hazards setting variant will obviously be the most common, yet its speed prevents it from being Taunted easily, can easily destroy faster Taunters and can utilise its high speed to simply come back in for Round 2 to set them up again. Scolipede has bar none the best physical movepool you'll ever see on a Bug type ever (eat your heart out Genesect), and it has Swords Dance. Even seemingly-soild checks like Golurk, Rhydon, Regirock, and Golbat become iffy if hazards (SR for Golbat) are on the field and faced with +2 or even +1 Aqua Tail, EQ, Superpower or Rock Slide. Misdreavus and Weezing can stop this if they're healthy, but fall prey to the hazard Pede, who gets up at least 2 layers before Missy's Taunt or Weezing's Fire Blast. Did I mention this thing gets Baton Pass, which is incredible for an offensive pokemon that can force so many switches? +2 Attack Swellow, +2 Defense Musharna and +2 Speed Sawk or Golurk can get pretty dangerous. Even dry pass in an option for CB Sets.
