Pokémon Sword and Shield - Supposed leak

Looks like that pixel art from shyguyxxl of the vicious troublerone on the vinebooru.

From what I can gather it seems to be based on this, commonly known as the Peanut-Head Bug or Alligator Bug. Only in this case it seems to combine the aspects of both common names while also being Dragon because, gator = reptile = Dragon I guess.
