Any starter for a new Pokémon generation will invite comparisons — to other monsters, to real creatures, and to other video games.
You've probably already heard some of these associations. Browt is obviously a green Angry Bird.
Gecqua? That's Sobble But Better. The fiery Pomeranian Pombon could be likened to all sorts of things, from the annoying dog in *Undertale* to a laundry list of canine Pokémon.
Chatter like this is normal and expected, but at least one resemblance is making Pokémon fans raise their eyebrows.
