Pheromosa

Boasting a ridiculous Attack stat and a solid moveset, Pheromosa's DPS is unrivaled by many. It is especially adept at being a Bug attacker, where not even Mega Beedrill can hold a candle to its raw power. It's also a fairly strong Fighting attacker, although there is more competition in that role.

However, DPS isn't the end all be all metric to raid viability, and to say that Pheromosa is fragile is an understatement. Although not anywhere as glassy as Attack Forme Deoxys, Pheromosa will still easily fold to resisted hits and strong Fast Attacks. Its typing also doesn't leave it with much resistances, and is weak to the Psychic-type bosses that it wants to counter. Adept dodging is required to circumvent its awful bulk, which it thankfully has no issues with due to Bug Bite's short duration.

Basically, Pheromosa is strong, but use with extreme caution.
