Breeding is easier than ever in Pokemon X & Y--and you know what that means, right? More people have picked breeding up, which inevitably led to more not-quite-perfect reject Pokemon. And the more you think about what these imperfect Pokemon have to go through, the more depressing the whole situation seems.
Now that Pokemon introduced Wonder Trade—which lets you put up a Pokemon for trade with a stranger—it means that many people dump their undesirable Pokemon on the service. It's an easy way to get rid of them. But from the Pokemon's perspective, well—it's kind of mean! Can you imagine how many times a Pokemon might go back into Wonder Trade before finding an owner that wants it?
Here's a comic from Renee P. on Tumblr that illustrates what I mean:
At least this has a happy ending, though....maybe I'm just a pessimist, but I don't think most Pokemon are as lucky as Bulbasaur :(
