Cobalion

Fighting

With its high defenses and Speed, Cobalion serves as an excellent lead and defensive pivot for Fighting-type teams. Cobalion's good Speed tier and access to Taunt and Stealth Rock allow it to lead effectively against opposing entry hazard setters. Additionally, its Steel typing offers many valuable resistances and key neutralities to Fairy-, Psychic-, and Flying-type moves, giving Cobalion ample opportunities to switch into attacks and check Pokemon, such as Latios and Mega Diancie, that threaten Fighting teams. Cobalion's Steel-type STAB Iron Head is also an asset to Fighting-type teams, threatening the Fairy-type Pokemon they're weak to. However, Cobalion is generally passive with its mediocre offensive stats and can only threaten a lot of Pokemon with Thunder Wave. Cobalion's lack of recovery also hurts its longevity, making it difficult for it to switch into threats multiple times over the course of a battle. On a type with poor defensive synergy, Cobalion's weakness to common Fire-, Fighting-, and Ground-type attacks is difficult to cover.
