>>57188461Articuno had the same Special stat as Moltres and Zapdos in Gen 1 giving it 125 base Special Blizzards. In fact, Articuno's Blizzard is the strongest non-boosted attack in the game, even beating out Mewtwo's Psychic.
Articuno Blizzard vs. Tauros: 191-225 (54.1 - 63.7%) -- guaranteed 2HKO
Mewtwo Psychic vs. Tauros: 166-196 (47 - 55.5%) -- 76.2% chance to 2HKO
Oh yeah, and Blizzard is 90% accurate with a 30% chance to OHKO the opposing Pokemon. And EVEN STILL, it's not considered as good as Zapdos.
