Scolipede

Bug

Scolipede's ability in Speed Boost and access to Swords Dance make it a dangerous sweeper with great matchups against Poison, Fire, and Psychic teams. This is further bolstered by its decent movepool, particularly its access to Earthquake and Rock Slide, allowing it to take on huge threats for Bug teams such as Heatran, Mega Charizard Y, and Toxapex. Its high Speed allows it to outspeed common threats like Latios and Mega Diancie. However, Scolipede misses out on a lot of important KOs and needs its checks and counters severely weakened to sweep, although Swords Dance can remediate this problem. Its coverage has limited range, as it can't hit common Pokemon such as Celesteela, Gliscor, and Porygon2 too hard. Scolipede also has mediocre bulk and is susceptible to all entry hazards bar Toxic Spikes, which means it can only come in via aggressive double switches or after a Pokemon has fainted. This also leaves it easily revenge killed by priority moves users like Mega Pinsir, Azumarill, and Scizor. Lastly, it suffers from competition from other, more reliable setup sweepers like Mega Scizor and Mega Pinsir. However, unlike them, Scolipede doesn't waste a Mega slot.

Poison

• Scolipede's movepool, great Speed, and decent Attack allow it to serve as a potent offensive wallbreaker, sweeper, or cleaner.
• Scolipede is one of the only few viable physically offensive Pokemon for Poison; its Bug-type STAB makes it a powerful force against Psychic and Dark teams. It is especially huge in the Psychic matchup, where it has the potential to outspeed and decimate threats such as Latios and unboosted Mew that would otherwise have an easy time sweeping most of the Pokemon on Poison.
• Access to Rock Slide and Earthquake allows it to check common threats from Electric, Poison, and Fire teams, such as Heatran and Mega Charizard Y.
• Speed Boost is a fantastic ability, allowing Scolipede to outspeed and decimate common threats like Latios and Tapu Koko after merely one boost; this makes it easier to clean late-game.
• However, Scolipede is rather fragile and easily worn down by Life Orb recoil, meaning it is vulnerable to being OHKOed or revenge killed by any decent neutral STAB move. Most notably, Scolipede suffers from a nasty weakness to Stealth Rock.
• Although it makes Scolipede neutral against Ground-type attacks, Bug is an underwhelming secondary typing defensively, to say the least, offering no other useful resistance while making it weak to common Fire-, Flying-, and Rock-type attacks.
• Furthermore, it is countered by common defensive threats like Celesteela and Ferrothorn, limiting its ability to clean late-game.
