Marvel Comics/Siryn

**Siryn** (Theresa Rourke Cassidy) is the mutant daughter of Banshee, although she was raised by Banshee's cousin, Black Tom Cassidy, hidden from her real father.

## Powers and Abilities

**Sound Manipulation:** Siryn has the ability to create various sonic effects through the combined action of her vocal cords and limited, reflexive psionic powers.

* **Sonic Scream:** Siryn can cause her vocal cords to vibrate over a wide range of sonic frequencies and produce a volume of sound ranging up to at least 140 decibels. She can use her voice to shatter solid objects with her sonic screams.
	+ **Flight:** Siryn can use the sonic vibration sof her scream to fly at the speed of sound.
	+ **Sonic Blasts:** By focusing her sonic vibrations while screaming into an intense beam, she can generate a "battering ram" of sonic energy with great concussive force that can liquify and disintegrate targets.
	+ **Equilibrium Disruption:** She has the ability to alter someone's balance by affecting their equilibrium by using her sonic scream.
* **Echolocation:** She can use her sonic powers as a form of sonar. By sending out a precise, pure note and listening to the returning, altered wavefront of the note, she can evaluate her surroundings in total darkness with varying degrees of resolution.
* **Sound Immunity:** She generates a psionic field that protects her from the detrimental effects of her powers. However, she can still be injured if pushed beyond certain limits.
* **Vocal Persuasion:** Siryn has the ability to subtly influence a person's subconscious mind by changing the tones and vibrations of her voice. The effects of this capability tend towards blatant hypnosis.
* **Unconsciousness Inducement:** She can affect the fluid in a person's ear so as to render them unconscious.
* **Selective Hearing:** Siryn can focus on or completely block any given sound in her environment. This not only allows her to be unaffected by her own powers but also to be extremely talented in surveillance situations.
* **Superhuman Stamina:** Her vocal cords are tremendously strong so that she can produce her sonic effects through screaming for hours at a time without noticeably tiring or injuring her vocal apparatus.
* **Superhuman Durability:** Siryn's vocal cords and the interiors of her throat and mouth are also superhumanly tough to endure the intense pressures and constrictions that she produces so as not to cause her any injury.

**Godly Aspect:** After killing the Morrigan, it is assumed that Siryn gained all of the former's abilities, including:

* **Immortality:** As a god, she does not age, although she can be killed through external means.
* **Superhuman Durability:** Siryn was able to take a direct hit from a gun that was able to destroy Layla Miller's shield without feeling discomfort. Even still, she can die from falling from very high points.
* **Teleportation:** When Siryn first gained her godly powers, she was able to blink out of existence and appear next to Multiple Man.
* **Location Detection:** Siryn was able to deduce exactly where Multiple Man was and teleport to him simply because he was praying to her.
* **Avian Manipulation:** She has the ability to control crows.
* **Healing:** She can heal people even from the point of death.
* **War Manipulation:** She can affect areas of war and battle.
* **Death Manipulation:** She can affect areas of death.
	+ **Death Inducement:** She can weaken someone to the point of death.
* **Shapeshifting**
* **Power Bestowal**
* **Power Negation**
* **Power Removal**
