Moltres

Moltres is GSC OU's most consistent Sunny Day attacker. It has the highest Special Attack out of any Fire-type, and with the help of Charcoal and Sunny Day, it has extremely high odds to 2HKO Snorlax after Spikes. Moltres's defensive stats are also quite solid, and its typing enables it to answer common threats like Exeggutor, Steelix, Forretress, and Heracross. In addition, it makes for a decent sleep absorber, and its Spikes immunity can be quite useful for longer games. Moltres best matches up versus offensive teams that lack Fire-resistant Pokemon, in particular when Steelix is used as the only Normal-type check with a Zapdos / Snorlax / Cloyster core; unless Vaporeon or Charizard is used in one of the slots, the other two Pokemon likely do not resist Fire. Some examples of those Pokemon are Nidoking, Jynx, Exeggutor, Machamp, and Gengar. In addition, Moltres can wreak havoc versus traditional defensive teams that replace Suicune with Umbreon.

Despite Moltres's potential to 2HKO Snorlax, it's still not favored in a one-on-one matchup; its best chances are if sun has already been set up, but Snorlax can use Self-Destruct to take Moltres down with it. Usually Moltres's only attack is Fire Blast, so Water- and Rock-types like Vaporeon, Suicune, Tyranitar, Rhydon, and Golem will often stop it in its tracks. Moltres also struggles versus Zapdos and Raikou if they switch in safely, as they outspeed it and threaten it with their powerful Electric-type attacks.
