Etna is depicted in a poised, slightly mischievous stance, her head tilted and a confident smile playing on her lips. Her long, flowing hair fans out behind her, with sculpted strands catching the light. She wears a dark, elaborate outfit with layered fabrics, intricate armor-like elements, and demonic motifs that hint at her status in the Netherworld. Fine paintwork highlights her eyes, hair gradient, and metallic accents. The base integrates arcane runes and Netherworld flora to evoke Makai ambience. The wings and horns are delicately rendered, with sharp edges and translucent shading. The overall sculpture balances elegance with threat, matching Etna's witty, dangerous personality that fans recognize.

Etna's arc across Makai Senki Disgaea centers on her ascent within the Netherworld's volatile power structure, where wit, charm, and cold ambition coexist. She uses clever schemes, magical skill, and sharp dialogue to maneuver rivals and allies alike, often tipping the balance in her favor. Though her scenes with Laharl reveal a competitive partnership, her loyalty is ultimately contingent and self-serving, yet never devoid of moments of genuine care for those she tolerates. Her interactions with other characters reveal a mix of teasing bravado, protective instincts, and reluctant admiration, making her one of the series' most enduring and dynamic figures. She remains a flexible strategist, shaping alliances, pursuing power, and stepping forward in moments of crisis to steer events with confidence and flair.
