Adamant Dragonites have to be careful of being outsped by Jolly Brelooms, too.
Salamence - Much like Dragonite, Salamence only fears Stone Edge and Spore, but Intimidate variants can further soften Breloom's attacks up. Once Sleep Clause is in effect, Salamence doesn't mind coming in on most Brelooms.
Volcarona - An unconventional counter, as its defense is low, and Stone Edge is guaranteed 1HKO. However, he resists both of Breloom's STABs, and has a chance to burn it with Flame Body, crippling it for the rest of the match. It can also revenge Breloom in a pinch.
Checks
Thundurus-T - It outspeeds Breloom, resists Mach Punch, and 1HKOs with Hidden Power Ice. It doesn't like Spore, or Stone Edge, so it should only be considered as a revenge killer.
