Slime

Slime are the most popular species of the Dragon Quest series, and unarguably the mascot of the entire franchise. There are a variety of species of Slime, though the most popular are Blue Slime, though there are hundreds of different types. Slime, while commonly enemies, have also appeared as heroes, evident in games such as Dragon Quest Heroes: Rocket Slime, which stars the blue Slime Rocket as the protagonist. When Enix (creator of the series) merged with Square, the Slime was generally thought of as Enix's mascot, whereas Square had Final Fantasy's Chocobo.
