Achilles is the name of Captain Phoebus' horse in The Hunchback of Notre Dame. He appears in both the original film and the sequel, being much snarkier in the sequel and answering rhetorical counting questions Phoebus poses by tapping his hoof.
His name was purely based around one joke- the "Achilles, heel!" line in the original movie. He quite nearly ended up nameless, but due to that one play on words, he received his name.
Also later in the first movie, during the final fight, Phoebus says "Achilles, sit" and the horse sits on an enemy's head. In the 2nd movie, during the Festival of Love, he found love in the end.
- Achilles was named after the Greek hero, Achilles from Greek Mythology.
- Achilles is the dim witted cousin of Philippe from Beauty And The Beast as stated in the audio commentary of The Hunchback Of Notre Dame on DVD.
- A running gag is Phoebus telling Achilles to sit which results Achilles comically sitting on a person.
