WELP! HERE WE GO.
5. Purugly
Glameow was one of my favorite Pokemon to use in generation 4. And when I was looking forward to it to evolve and it did...holy...why? I didn't feed you that much did I? P.S. you may find out that design is one of the things that I will focus on for the most part.
4. Elemental Monkeys
Design. As well as everything everyone else who hates them said.
3. Aromatisse
Sigh...why? What is up with its design? Why does it resemble a hooker? Why does it look like a bird, but it isn't a flying type? I have more questions than answers.
2. Burmy & Wormadam
These two. Probably one of the worst designs for a Pokemon in my opinion. Plus I had an annoying faceoff against it in once. Plus, the fact that I was expecting to get a Mothim, but forgot that the evolutions were gender specific. Mothim, however, is one of my favorite bug types and stays off this list btw.
1. Unown
For obvious reasons and some internally hateful reasons as well. Obvious reason: it has only hidden power. Internal reason: has your pokemon ever been fainted by an Unown in a Heart Gold/Soul Silver nuzlocke because you couldn't run away despite being multiple levels above it? If I recorded it, you would have seen one of the biggest rages I have ever done. And this is coming from someone who faced Charlotte 15 times before (Episode 14 version before nerfs) and Angie on Intense Mode even more times on Pokemon Rejuvenation.
