Ribombee

Ribombee can be a passable option as a fast special attacker thanks to its high Speed tier and good coverage. It can revenge kill an assortment of offensive threats, including Choice Band Zygarde-10%, Nasty Plot Salazzle, Noivern, and Virizion, and has Quiver Dance to beat Choice Scarf users that would otherwise revenge kill it. Ribombee also has a few appealing support options in Sticky Web, Tailwind, and Defog, which could potentially fill holes in a team. Unfortunately, several large weaknesses prevent Ribombee from being very common in the metagame. While Bug / Fairy isn't a terrible defensive typing, Ribombee's absurd frailty means it can only switch into passive walls and weak resisted hits. Anything remotely strong, even resisted, will likely 2HKO it. While fast, it still is outsped by every relevant Choice Scarf user when unboosted, and most of them will OHKO it as long as Stealth Rock is up. Priority users such as Machamp and Zygarde-10% can also prove troublesome. Having average Special Attack for a sweeper forces Ribombee to use its Z-Move to revenge kill prominent threats like Virizion, leaving it depleted for potential future sweeps. Finally, common special tanks on bulky teams like Registeel, Snorlax, and Bronzong can weather even boosted attacks, making Ribombee struggle to successfully dent holes in such teams.
