Lysa appears solely in the 1992 film adaptation. She works in a Syracuse tavern, placing her among the common citizens suffering under King Dionysius's oppressive rule.

She actively opposes the king's tyranny by joining a resistance movement within Syracuse; this group works against his policies and seeks to undermine his authority, connecting Lysa to the film's broader political conflict.

Her role gains significance when she directly aids the protagonist. Recognizing his desperate need to return to Syracuse and save his friend, she provides him with a horse, facilitating his journey. This decisive action reflects both her alignment with the resistance's goals and her personal willingness to challenge the king's injustices.

Lysa gives voice to the perspective and struggles of ordinary citizens under the king's harsh regime. Her character expands the narrative beyond the central friendship plot, illustrating the wider societal impact of the king's paranoia and cruelty. She epitomizes the populace's resilience and their collective desire for change.
