Zephyr first appears in Quasimodo's room to which he and Quasimodo play Touril and then his parents come in and tell him to slow it down to which he rightfully obeys his parents. They then look at the bell La Fidele.
Zephyr is the son of Esmeralda and Phoebus. He is a young boy who enjoys the circus and dislikes kissing. He also has a strong friendship with Quasimodo.
Zephyr's name means "West wind", a possible reference to his strong friendship with Quasimodo, as well as the boy's energetic behavior. It is also the name of a Greek wind god, likely a reference to how his father is named for a sun god.
Haley Joel Osment was 9 years old when he recorded the voice, but he was 14 when The Hunchback of Notre Dame II was released five years later.
In the trailer for The Hunchback of Notre Dame II Haley Joel Osment is credited as his first ever appearance in a film. This was false, as he had already been acting for a few years before 2002. His first major movie role was in Forest Gump (1994), and between the creation and release of The Hunchback of Notre Dame II, he achieved official stardom for his roles in The Sixth Sense (1999), Pay It Forward (2000) and A.I. Artificial: Intelligence (2001).
Zephyr is one of two boys to be the sons of Disney Heroines, the other being Danny Darling from Peter Pan 2. All other Disney Heroines have daughters.
