Scolipede

Poison

Scolipede is very reliable on Poison teams because of its ability Speed Boost, which makes it a great cleaner and allows it to outspeed common Choice Scarf users such as Victini, Latios, and Kyurem-B. Scolipede also has access to reliable coverage moves such as Superpower, Aqua Tail, Rock Slide, and Earthquake, which allow it to check many Pokemon in the metagame. Scolipede's base 100 Attack stat coupled with Choice Band, Life Orb, or Swords Dance lets it function as an effective wallbreaker. Scolipede's typing sets it apart from other Poison-types, as its Bug typing and STAB Megahorn allow it to check Psychic-types that pose a huge threat to Poison teams, and it can take a couple of Ground-type attacks from powerful attackers.

Unfortunately, Scolipede's typing makes it weak to Stealth Rock, limiting its opportunities to switch in. Scolipede also lacks reasonable bulk, meaning it can't take advantage of its neutrality to Ground-type attacks and can be revenge killed by priority moves. Despite being immune to Poison, Scolipede is vulnerable to other status effects such as burn and paralysis, both of which prevent Scolipede from being a late-game sweeper by hindering its effectiveness to either deal a lot of damage or outspeed other Pokemon. Scolipede also suffers from four-moveslot syndrome, which makes it unable to check every single type.
