Dual-type eeveelutions feature in Pokemon Storm/Wave's (free) DLC, with the introduction of a special area that heightens the power of Infusion stones. Using the right stone on an eeveelution here will cause its cells to mutate again, as it takes on a secondary type and changes its form.


Plumeon, the windblown pokemon
Plumeon is the result of giving a leafeon an Infused Pearl in the Infusion Chamber. Its body is incredibly light and with one leap it can catch the wind, using its collar to stay aloft and steering with its tail and ears. Because it is so intolerant of cold temperatures it uses the winds to head south for the winter, and can be lofted well above the clouds, travelling for thousands of miles before reaching land. Because they can control their trajectory they look for landing sites with a rich, fertile environment and often land far away from people.


Yeteon, the double diamond pokemon
Yeteon is the result of giving a glaceon an Infused Diamond in the Infusion Chamber. Its body is hard as glacier ice and just as cold to the touch, though the fur covering it wears is warm and soft - it seems to be a trophy from a tough battle. Yeteon can be aloof and cold even with their trainers, but when they get angry they are a fearsome sight to behold, thrashing and scratching with furious abandon. Wounds inflicted by their claws can cause hypothermia in a matter of minutes, and they capitalize on their prey's reduced reaction time to deliver decisive blows.
