Twelve participants interacted with the system via mouse and keyboard for 20 minutes.
All transitions used in-engine animation crossfades and voice-filter changes (pitch shift, reverb). Twenty participants (12 M, 8 F; ages 19–45) rated their experience on 7-point Likert scales. toonxrole
A fox character (“Fen”) begins as a pickpocket antagonist (Narrative Gravity: Medium; Register: Sly comedic). If the user offers the fox three coins without attacking, Fen transitions to a thief-with-a-heart-of-gold ally (Gravity: High; Register: Reluctant heroic). If the user instead chases Fen into a chapel, the fox becomes a penitent confessor (Gravity: Low; Register: Melodramatic). Twenty participants (12 M, 8 F; ages 19–45)

Animated characters, role theory, dynamic narrative systems, character adaptation, ToonXRole, interactive storytelling. 1. Introduction In classical animation—from Disney’s Twelve Principles to Warner Bros.’ slapcode—characters are assigned a fixed ontological role (e.g., Bugs Bunny as Trickster, Elmer Fudd as Hunter). These roles drive gag structures and audience expectations. However, interactive and serialized animated content (e.g., South Park: Phone Destroyer , The Amazing World of Gumball ) increasingly shows characters bending or breaking their archetypes in response to user choices or episodic needs.
