I don't think evolution is always ugly. It certainly is sometimes, and evolving some Pokemon has made me sad for that reason (Horsea), but some I think look good. I think Vulpix is cuter, but Ninetails certainly isn't ugly. Also, I think Arcanine looke 100 times better than Growlithe. Growlithe is adorable, but Arcanine looks so beautiful to me. Another example is Houndour and Houndoom. Houndoor is cute, but I much prefer when it has transformed in to Houndoom. Meowth and Persian. I would take a Persian over a Meowth any day.
