Kabutops

Kabutops is one of the best Pokemon on rain hyper offense, due to its ability, Swift Swim, and great Attack, which lets it 2HKO some of the best physical walls in the OU metagame after a Swords Dance. While Kabutops has a small movepool, it has everything it needs. The only Pokemon not covered by its STAB moves alone, Ferrothorn, loses to a Swords Dance-boosted Low Kick. Gastrodon and Chesnaught are 2HKOed by Low Kick on the switch as well. Another great trait about Kabutops is that it stops Talonflame on rain offense teams. However, despite all that Kabutops has going for it, it does have some flaws, including lackluster Special Defense and a mediocre defensive typing, meaning that its decent Defense stat rarely comes into play. Another glaring flaw is that outside of rain, Kabutops isn't an excellent Pokemon due to the huge drop in Speed. Nonetheless, Kabutops is an excellent sweeper to use on rain teams.
