Moltres

Moltres fits incredibly well in the tier and has the ability to fulfill roles nothing else can. Moltres's stats are solid by UU standards, and its typing is a mixed blessing: Fire / Flying provides fantastic offensive coverage, resistances to important types, such as Bug, Steel, Fighting, and Fire, and an immunity to Ground-type moves. However, Moltres is weak to Water-, Electric- and Rock-type moves, with the latter also bringing a 4x weakness to Stealth Rock, which is a significant inconvenience but is manageable thanks to the good availability of Defog users. Moltres's abilities also are rather niche, its movepool is somewhat limited, and it can be very one-dimensional and predictable, but despite this, it has all the tools it needs to be a major threat in the UU tier.
