Basically, Dunsparce is popular for being unpopular. Dunsparce is known for being odd looking, rare, and pretty mediocre performance-wise. Because of this and the fact that it's been a prime candidate for an evolution for the past decade, people generally saw Dunsparce as being a neglected, forgotten Pokemon. However, this sentiment became so well known that it's now an oxymoron. Everybody knows Dunsparce. Everybody knows how weak and rare it is. Go to any "most-forgotten Pokemon" thread on any site and you'll see at least one person mention Dunsparce, despite the fact that a Pokemon being well-known for being unknown is a perfect example of an oxymoron. Sure there are some hipsters who like it, despite not seeing the irony of doing so, but most fans of Dunsparce just like it because it's weird. This rare, stand-alone oddball that's aesthetically a mix between cool, weird, and cute that's base on a cryptid that's pretty obscure, at least to most English-speakers, certainly does have character.
