(I'm letting everyone know that I think this pokemon is really good in battle, but it's ugly as fuck so it has to be #2)

It's something that comes out of a rock. Not quite sure what lol. While I have tons of respect for this pokemon in aspects I'm not judging on, this was what I THOUGHT would be the ugliest pokemon to ever come in to existence. Many people think it's cool but to be honest, it's just way to disgusting looking for me to like it's design. Sorry Spiritomb...
