Buzzwole

Bug

Thanks to its high Attack stat, decent movepool, and ability in Beast Boost, Buzzwole is an effective revenge killer for Bug-type teams. It also has a high Defense stat, which lets it shrug off priority moves from the likes of Dragonite, Scizor, and Azumarill, and its Fighting typing combined with good physical bulk lets it take on threatening Pokemon like Terrakion and Tyranitar for Bug-type teams. However, Buzzwole has a middling Speed stat, which makes it unable to outspeed faster Pokemon such as Choice Scarf Latias and Blacephalon. Buzzwole's low Special Defense stat also means it takes decent damage from even weak attacks like Toxapex's Scald.

Fighting

Choice Scarf Buzzwole is one of the best revenge killers and late-game cleaners for Fighting teams thanks to its high Attack, good physical bulk, and incredible ability in Beast Boost. Its Bug-type STAB move is mandatory for Fighting teams to deal with otherwise problematic Psychic- and Grass-types like Alakazam, Mew, Celebi, and Rillaboom, and its Fighting / Bug typing allows it resist Ground- and Fighting- attacks, increasing its chances to switch in against Pokemon like Excadrill and Terrakion. Buzzwole is vulnerable to status like paralysis and burn from Pokemon like Zapdos and Galarian Corsola, as paralysis cripples it and limits the possibility to act as deadly revenge killer, while burn halves its offensive power. Buzzwole's Speed tier is average, and it also has poor special bulk, so faster threats like Choice Scarf Blacephalon and Choice Scarf Tapu Lele outspeed and revenge kill it. It faces competition with Heracross due to having the same typing, but Heracross has a stronger Bug-type STAB move and better Speed and Special Defense. However, Buzzwole has more coverage options than Heracross, which help in a lot of different matchups like Flying and Dragon.
