Background:

Once a celebrated opera singer in Europe, Isabella Devereaux discovered her metahuman abilities when her voice shattered an entire concert hall during a performance. While initially trying to use her gift for good, an accidental sonic-induced death led her to be blacklisted from the industry. Disillusioned and bitter, she abandoned her former life, seeking power and revenge against a world that rejected her.

She moved into the underground criminal world, using her abilities to become a highly-paid enforcer and manipulator, often blackmailing high-profile figures with her unique ability to influence minds through sound frequencies. Over time, she embraced her villainous persona, using her voice to sow chaos and discord across New Zealand.

Her downfall came when she attempted to destabilize Wellington by triggering city-wide sonic riots, only to be captured by the New Zealand Meta-Security Force and imprisoned in Blackstone Hold.

Powers/Skills/Abilities/Weaknesses of Note:

Powers:

• Sonic Manipulation – The Siren can generate and control sound waves at an extreme level, using them for offense, defense, and mental influence.
• Hypnotic Voice – Through careful modulation, she can induce hallucinations, suggest actions, or lull victims into a trance-like state.
• Sonic Blasts – She can unleash high-intensity sound waves capable of rupturing eardrums, shattering glass, and even breaking bones at close range.
• Resonance Shield – By adjusting frequencies around her, she can create a barrier of sound waves that deflects physical projectiles and disrupts electronics.
• Echolocation – Can use sound waves to navigate in complete darkness and detect hidden individuals or structures.

Weaknesses:

• Silence Nullifies Her Powers – If unable to produce sound, she is completely powerless.
• Hearing Sensitivity – While resistant to most sound attacks, she is vulnerable to counter-frequencies specifically tuned to disrupt her control.
• Physical Durability – She relies on her abilities for protection and is not physically enhanced. A well-placed attack can incapacitate her.
• Power Fatigue – Extended use of high-intensity sonic abilities strains her vocal cords and lung capacity, forcing her to rest between major attacks.
