Mascot Species from Worst to Best
Every once in a while, games and game series will feature fictional species of animals which show up throughout the game and scream marketing, whether because they were designed for the sole purpose of marketing or because they just happen to be perfect for it. In fact, quite a few of these have appeared in video games over the years, begging the question: "what's the best mascot species ever made?"
Note: In the case where something is an established mascot character rather than part of a mascot species (ie: Ash's Pikachu instead of just Pikachu, or Tamadra from Puzzle Vs. Dragons), they are not eligible for the list. Also, some of these species have concept pages, some don't. In cases where they don't I'm just going to put the game on the list, and denote the species in question.
