IMO Pogies that look different depending on the gender shouldn't have ever been considered in the first place...
Purrugly is SUPPOSED to be ugly, which is why I don't really think it's that ugly. That's why it's called PurrUGLY. Not Purrpretty.

There's a list of more Pogies that I thik are semi-ugly but I won't list them because there's too many of them. This is also only a list of D/P Pogies so the list is supposed to be small. I do think that Nintendo is running out of ideas when it comes to new Pokemon. The first gen. of Pokemon was the coolest, the second gen was pretty cool, the third gen was where Nintendo began running out of ideas. Now the fourth gen comes by and a lot of the newer Pokemon are starting to look really ugly. Half of them look like aliens from another planets, some of them are made to be far too cute, and some look like inanimate objects. I promised myself that I would't buy any future generations of Pokemon unless they looked cool like the first two gens. or they combined all the worlds together.
