However, there are a couple of characters that might remind you of furries:
* Mr. D (Dionysus): He's the Greek god of wine, revelry, and theatre, who appears as a flamboyant and often overly-enthusiastic human. While he's not literally furry, his eccentric nature and playful demeanor might resonate with the image of a furry.
* The Minotaur: This monstrous creature with a bull's head and a human body has a connection to the underworld. It's possible some might see him as a furry due to his animal-human hybrid form.
However, it's important to remember that the concept of "furry" as a modern fandom is a very recent one, while *The Lightning Thief* was published in 2005. Therefore, it's unlikely that author Rick Riordan was intending to include characters that fit into that specific cultural context.
