Fiore, also known as Hans, is a non-human anthropomorphic squirrel character in the 1981 anime adaptation of Swan Lake. He acts as a companion to Prince Siegfried alongside his fellow squirrel, Margarita.

Primarily serving a comedic and observational role, Hans functions much like a Greek Chorus, offering commentary on the central romance between Siegfried and Odette without driving major events. He possesses a playful and sometimes impulsive nature.

Hans attempts a direct intervention during Siegfried's clash with the sorcerer Rothbart. This defiance provokes Rothbart, who magically transforms Hans into a toad as punishment. Hans remains trapped in this form until Rothbart's defeat and death finally break the enchantment, restoring him to his squirrel shape.

His relationship with Margarita includes light romantic moments, occasionally mirroring the main couple's dynamics in a simpler way. Margarita often urges Hans to demonstrate courage, especially against Rothbart, underscoring a difference in their personalities.

Together, Hans and Margarita provide narrative levity and simplicity contrasting the primary romantic tragedy. Their presence introduces an element of child-friendly adventure not found in the original ballet.
