Hydreigon

​ Hydreigon is an incredibly powerful special attacker in Battle Spot Singles, capable of running numerous different sets both as a wallbreaker and a revenge killer. Its Dark / Dragon typing grants it fantastic neutral coverage that hits every type bar Fairy for neutral damage, allowing it to threaten many popular threats such as Aegislash, Cresselia, and Rotom-W. Between Draco Meteor and Dark Pulse, few Pokemon beyond Chansey and Fairy-types have an easy time switching into Hydreigon, and a very diverse movepool with coverage options including Fire Blast, Earth Power, and Focus Blast also complements Hydreigon's powerful offensive presence. Hydreigon's ability to run both Choice Specs and Choice Scarf effectively also allows it to threaten both offensive and defensive teams and adds an element of surprise that can throw an unsuspecting opponent off guard. Defensively, Hydreigon's typing alongside Levitate grants it a wide range of resistances and immunities, which helps it find numerous opportunities to switch in and start punching holes in the opponent's team. However, while base 98 Speed places Hydreigon in a decent Speed tier, it leaves it just short of the important base 100 range, which in turn leaves it outsped by many threats when it's not holding a Choice Scarf, including Mega Kangaskhan and Garchomp. Hydreigon is often reliant on Choice items as well, which makes it more predictable and can risk giving an opponent a free turn. Fairy-type Pokemon also ruin Hydreigon's day, so it always needs a teammate that can help deal with threats such as Azumarill and Sylveon before it can start breaking teams with Draco Meteor and Dark Pulse. However, despite these shortcomings, Hydreigon still stands as one of the most effective special wallbreakers in the format.
