Name and design is funny. I used a Roggenrola for the Unova region game and it was at times helpful and other times not so much. I used Roggenrola against Lenora and Elesa but their Pokemon were still able to do quite some good damage on Roggenrola.
Hate it. The entire line is in my least favorite books, but Conkeldurr especially. And it's as ugly as can be. Plus I could never get the pronunciation of its name right until Hawlucha's capture in XY.
I didn't like it much at first, but now I think it's pretty cool. I really love it's colour palette. I still think the head looks too big for its body though, but eh, it's not as distracting to me as it was before.
It's also one of my sister's top 10 favourite Pokémon as well, so yeah
