Well, I must confess that part of it is personal. My mother was a kimono girl, and she had kept her espeon from her days as such. So in truth, I have grown up alongside one of eevee’s evolutions, and many of my fondest memories (as well as those that are … not-so-fond, admittedly) involve that very espeon or the eevee kits she mothered.
Additionally, yes, part of it is for scientific curiosity, as while the general idea of how eevee can have so many alternative evolutions is known, there is still a vast body of questions concerning its genetic code and how many evolutions it actually has. For example, scientists are discovering new evolutions every few years, and we are still not certain as to whether or not eevee can possess an evolution that boasts more than one type.
Not only that, but also, the fact that it accepts evolution so readily makes it an ideal subject for evolutionary scientists in much the same way as the fruit fly has been the subject of much genetic research. Eevee alone has unlocked or may unlock many of the secrets to pokémon evolution that had plagued researchers for centuries.
And finally, how can anyone resist such a cute button nose or those fuzzy ears and tail? Honestly.
All of this is true, although I still question my partner’s opinions. I, for one, can resist eevee’s “cute button nose” and “fuzzy ears and tail” quite easily. Skitty and clefairy are far, far more charming. —LH
I’m sure they are if you enjoy having all your wires chewed up or covered with clefairy’s crystalline spit. —Bill
