Hydreigon

Hydreigon's high base Special Attack and good overall stats are part of what makes it an important threat in the UnderUsed metagame. Hydreigon's typing gives it almost perfect neutral coverage with its STAB moves; the only type that resists both is Fairy. Defensively, Hydreigon's typing has some great resistances and, taking Levitate into consideration, two immunities. Hydreigon's movepool is simply fantastic, which makes it a really versatile threat. However, Hydreigon's weakness to Fighting- and Bug-type attacks, both of which are common in UnderUsed, and the fact its base 98 Speed isn't that great, make it hard for Hydreigon to deal with offensive teams.
