Leafeon. Kind of the odd one out of the group, yea, but probably the thing I like the most about Leafeon is the aesthetics of it, which got me really appreciating it when I had basically done a project with one in a digital art class I was taking in school. It's also the most physically defensive of the three eevee's, wierdly, but that uniqueness is what wins me over in the end lol
Glaceon, because I really like ice types, and its design is the most intriguing to me. My opinion might change if a flying type Eeveelution is released, though.
Umbreon has always been my favorite. I like it's sleek and simple design. Also, dark types are the best.
Jolteon! The reason I love Jolteon so much is because of how it looks more canine-like than the other eevees, which makes it stand out more. Espeon and Glaceon are a close second and third though!
Didn't we already have like five of these threads? What ever, I'd love to express my love for Glaceon any day of the week. I've always loved ice types and Glaceon is my favorite (ignoring ninetales). Over the other Eeveelutions, I love the design of Glaceon.
I think I've used all of the Eeveelutions except Vaporeon and Glaceon. I'm not sure why I've never used a Glaceon (I even have a shiny one I got as a gift from a friend) but Vaporeon's design just bothers me for some reason and I don't know why. Espeon and Sylveon are probably my favorites, but Leafeon and Umbreon are close behind.
My fav Pokémon- SYLVEON!! Its adorable and I just love its ribbons! And oh....its eyes... I just LOVE it!!!
It's hard to choose, but I guess Umbreon. I like its sleek design and the black and yellow color scheme looks cool.
