Are there any Pokemon that you hated when you first saw them, that grew on you later?

When Bewear was first revealed, I thought it was absolutely atrocious, and the single worst Pokemon design to be created thus far. After some time has passed, though, I've actually found myself starting to tolerating it a bit more, and I even find it a bit cute and cool. I mean, it's still probably near the bottom end of the spectrum for me, but I guess I turned out to appreciate it a little more than I thought I ever would have. Anyone else have a similar experience?
