Decide between the eeveelutions? Oh, you are cruel!
So, firstly, vaporeon. Looks like a blue fox crossed with a fish. So far so good, then. In fact, before we move on, can I just say that vaporeon is without doubt one of the most beautiful pokemon to date? Well, I have said that now, so it's a bit late to say I can't. Now I think I must also mention that, as far as I'm concerned, he is, and has always been the most powerful eeveelution, with loads of hp, and strong special stats. He can also have good physical defence, if you invest in it, and burning enemies with scald makes him even tougher. Combine that with great healing, and useful moves like roar or haze, and vaporeon's seriously difficult to stop. Overall, vaporeon's my favourite pokemon of the whole first generation. Gives the others quite a lot of competition.
Jolteon's an interesting one. At first glance, he's a yellow fox with no tail and unusually spiky fur. Then you consider he's very small and energetic, and you have a seriously adorable pokemon. He's powerful, too, outspeeding just about everything which moves, and obviously everything which doesn't as well. He's one of my favourites for competitive use, since he can scout, revenge kill and clean up later on. And then he'll be back for seconds. And then you need to give him some tea to calm him down. So yes, jolteon is incredibly adorable, but his cuteness can kill. What's not to like?
And now flareon. Sadly, flareon has not been as fortunate as the others. But before I get into that, it's worth mentioning that she is very pretty, and very fluffy. And looks more impressive than the others. Sure, some are pretty, some are cute, but flareon definitely looks the toughest. Which is rather ironic. Flareon has been rather unfortunate in how game freak have treated her. Some sadistic designer saw fit to cripple both her speed and physical defence, leaving her neither fast nor tough enough to manage. Although, there is a certain niche in her special defence, which, boosted by an assault vest, allows her to work as a pivot of sorts. Worked okay for me, anyway. Take that, sadistic designers! Flareon has beaten you! Yeah, I guess she's a very neat eeveelution.
Moving onto the second generation, we have espeon. I like espeon. She's quite cute and quite elegant, and I like her tail. Uh, moving on, she's not half bad as a competitor, with magic bounce to annoy everyone, strong special attack and a steadily increasing movepool. Very nice. Also, special mention for her green shiny, which I always make bad puns about. But I'm feeling merciful, so I'll just conclude that espeon is a very nice pokemon.
Right, now let's see if I can talk about umbreon without mentioning my game on Platinum. Oh, wait, I just did. Yeah, yeah, the first time I ever saw or learned that umbreon existed was when my female eevee on Platinum evolved into one, much to my surprise. And then I named her Eclipse, blah, blah, blah, [insert love story here]. I'm not tired of talking about her, by the way, I just think no-one will want to read it. But anyway, umbreon is an extremely beautiful little fox, which immediately gives her a good starting point. She's also surprisingly tough, considering she looks so fragile, which is very nice for her, though there are a few moves she inexplicably doesn't learn, not that they'd help her. The main point is she's very pretty, and has special place in my heart. Eclipse, we love you!
Uh, moving on, the next generation graced us with leafeon. He's a very good-looking one, though I can't quite put my paw on exactly what word would be best to describe him, which is never a good feeling for a writer. Perhaps elegant? Probably. Anyway, he's not only smart, he's also athletic. He has an emphasis on physical stats, including speed, which is quite nice. He can't manage specially-based combat, though, which is a shame, and a big hindrance to him. But still, I very much like leafeon.
Then there's glaceon. Good old glaceon. She's very pretty, which is probably something you're tired of reading by now, but it's just true. Glaceon is beautiful. Competitively, mind, she doesn't measure up so well. While she can deal out a world of pain, she often doesn't get the chance, which is a shame for such a pretty creature. I would have to regrettably say she's the least powerful of the eeveelutions. Sorry, glaceon. You're still one of my favourites.
You're probably getting a tad sick of me saying positive things now. Well, you're in luck, because next is sylveon. Something about sylveon never quite stuck a chord with me, in the same way as the other eeveelutions did. Sure, she's cute, but maybe she's trying too hard to be cute. To be honest, she creeps me out. Something about her large, empty blue eyes, her glowy white fur. She just seems slightly odd, slightly 'off-key', if you like. The result is actually very effective; it's just she doesn't really appeal to me like the others. Sorry, sylveon. That aside, she's very good in battle, with her excellent special stats and hp, though she can't survive physically-based opposition. The opposite of leafeon, in a way. Overall, while I don't find her adorable, I do very much like her slightly creepy, other-worldly sense. Very effective.
Hmm, so overall, I think my favourite has to be umbreon. Wasn't that predictable? I may come up with a set of rankings, to be fairer to the others, but for now, I'll settle for just saying umbreon, my favourite pokemon of all.
