All eeveemon flavours
Flareon
BW2:Inhaled air is carried to its flame sac, heated, and exhaled as fire that reaches over 3,000 degrees F.
Whenever Flareon is hit by a flying type move, it takes no damage and gets its fire type moves increased in power. (Kinda like a flash fire but with a flying type immunity)
Jolteon
Silver: Every hair on its body starts to stand sharply on end if it becomes charged with electricity.
Whenever Jolteon uses Charge, any physical hits to Jolteon deal 12.5% damage to the attacker (like Iron Barbs)
Vaporeon
BW2: Its cell composition is similar to water molecules. As a result, it can’t be seen when it melts away into water.
In rain, Vaporeon increases evasiveness (like Sand Veil in a Sandstorm)
Umbreon
BW2: When exposed to the moon’s aura, the rings on its body glow faintly and it’s filled with a mysterious power.
When using Moonlight, a random stat of Umbreon's increases by +1
Espeon
BW2: Its fur is so sensitive, it can feel minute shifts in the air and predict the weather...and its foes’ thoughts.
Has both Forewarn and Frisk.
Leafeon
BW2: With cells similar to those of plants, it performs photosynthesis inside its body and creates pure air.
In sun, Leafeon is immune to any poison moves, as well as Toxic.
Glaceon
BW2: It lowers its body heat to freeze its fur. The hairs then become like needles it can fire.
Glaceon's attacks gradually get stronger the longer it stays in. This resets once it switches out.
