Snowshoes

Skye's Glaceon, (Skye's Glacia), nicknamed Snowshoes, is the seventh Pokemon obtained by Skye. Skye caught Glaceon as an Eevee alongside her brother, Sirius, who was a shiny Eevee at the time. The two were once in the possession of Charon, and while Sirius grew to like Skye, Snowshoes didn't. At Spear Pillar, during the final battle, Glaceon stepped up and defended Skye, and the two grew a friendship finally.

History
As an Eevee, Snowshoes was fairly shy and didn't like Skye, often hiding behind her older brother, a Shiny Eevee. Upon evolving into Glaceon, her personality turned even icier, and she liked blasting Skye and her friends with ice attacks and freezing them because she disliked her brother acting as Skye's 'pet'.

Glaceon eventually grew to like Skye and the two grew a bond.

Following her journies through Sinnoh, Skye dropped off Snowshoes and the rest of her Pokemon at his house, starting with a clean slate for her travels through Unova.
