When I first encountered Dunsparce on the original Silver Version, I was so intrigued by it. I can't say for sure why, but it was just so interesting.
Back before I had access to Internet, when I had little knowledge about the second generation and Pokemon gaming in general, which was also when I thought Dunsparce's name was "Dunsparence", I thought it evolved into Gligar. When I was younger, I liked to pretend that I was a professor of sorts, so I studied the similarities between them. They both had wings, fangs, a pointed tail, connotations with the ground (though only one of them was an actual Ground-type), and Gligar's National PokeDex number came immediately after Dunsparce. I spent ages trying to evolve what I thought to be Gligar's larvae, but Dunsparce would never evolve. In the end, I discovered it didn't evolve. I guess I got attached to it during that whole process. Of course, now I'm glad Dunsparce didn't evolve into Gligar.
For ages, Ho-oh was my favorite Pokemon. However, I decided not too very long ago that Dunsparce should be my favorite, as my reason for liking it wasn't solely due to its power.
While some recognize Dunsparce as "the Great Annoyer", most overlook this seemingly dull Pokemon completely. Thanks to its Serene Grace ability and massive status-inflicting movepool, Dunsparce can actually be a pretty decent Pokemon. I suggest giving it Glare/ThunderWave, Headbutt, Rock Slide, and Earthquake. King's Rock and Leftovers are both good items for Dunsparce. A Baton-Passing Ninjask with Substitute and Protect as a lead makes Dunsparce a nice sweeper. While it's certainly not the best Pokemon in the world, Dunsparce is vastly underrated.
I also caught a shiny Dunsparce a couple years ago, which makes me love the lil' guy even more. ^^
Plus, he looks so squishy. >w<
