Moltres

Moltres is an excellent Pokemon thanks to its ability to fulfill many roles with both offensive and defensive sets. It has a very useful typing that allows it to check Steel-, Fairy-, Grass-, and Fighting-types quite well and two high-powered STAB moves backed up by decent coverage and excellent Special Attack. On the defensive side, Moltres comes with solid bulk and access to Will-O-Wisp, Defog, and Roost; it is also a very solid check to Shaymin-S, and it can pivot around foes with U-turn. However, Moltres has a crippling weakness to Stealth Rock if not using Magic Guard and has a fair amount of competition from other Fire-types such as Heatran, which also fulfills multiple roles but does not come with a weakness to Stealth Rock and has a different set of resistances.
