Tourists from as far as Hoenn have been known to travel to Sinnoh in winter to see the Glalie command the snow, a sight of such beauty and majesty that pokemon contests in Sinnoh often take these months off, for they have such difficulty competing. The Glalie raise many a series of ice sculptures from the ground or transform falling snow into fast-moving images of falling pokemon, images that inspired the first animators.
Unlike the Cacnea, who do similar things with sand, Glalie do not use the snow to tell stories, for the effort required would distract them from their true calling. Glalie's control of ice is fundamentally a technique to win pokemon battles by turning the terrain into a weapon; their creations and shows are simply practice. By turning falling snow into a Pidgey's wings or a Rattata's fangs, Glalie learn to create edged shapes and harden snow for use in battle. When they learn to create sculptures by moving the snow with their power, they also learn to trap their foes in moving snow or summon walls to defend themselves.
Glalie remain too slow and dependent on favorable weather to win many matches in neutral conditions. But when battling at home, their practice pays off: their prowess in combat is legendary. After they have bested all foes in ordinary tournaments, many Pokemon League Champions have sought the strongest of Glalie villages in the midst of blizzards in the hopes of finding a new challenge. When this happens, the fans are nearly as excited by the Glalie's preliminary matches with one another, displays of command which use the ground and air alike as an icy and dangerous canvas, as they are with the Champion's challenge. And against a top Glalie in a blizzard, even champions often walk away defeated.
