Xerneas

Xerneas's niche in Balanced Hackmons is as a bulky Fairy-type stallbreaker with overall good offensive stats. Its Fairy typing allows it to excel in a metagame rampant with Dragon- and Dark-types, such as Giratina, Mega Tyranitar, and Yveltal. The same typing also gives it weaknesses to not commonly offensive types in Poison and Steel, which are fairly offset by its decent bulk. It is also the only relevant Fairy-type in BH with a Fighting resistance. However, it faces stiff competition offensively from Mega Diancie, which has higher offenses and defenses but is frail, and defensively from Mega Audino, which has better bulk; therefore, Xerneas is best suited as a bulky sweeper.
