Dunsparce, the Land Snake Pokémon. When discovered, the Dunsparce uses its tail to burrow into the earth and evade capture.
– Ash’s Pokedex
Dunsparce seems like another filler Pokemon. It has no evolutionary relatives, and isn’t that great competitively. For some reason, I keep on thinking it’s Ground type, probably just the design of it looking like it’s hugging the ground. Stunfisk, a Pokemon introduced in Gen V, looks like it could be related to Dunsparce.
Stat-wise, it has good HP, but nothing else stands out. I suppose its ability Serene Grace can be helpful, but there are better Pokemon with Serene Grace to use competitively, like Togekiss or Jirachi.
