# Silver Banshee

Silver Banshee is the name of two supervillains appearing in American comic books published by DC Comics, with both primarily as opponents of Superman.

## Publication history

Silver Banshee first appeared in Action Comics #595 and was created by John Byrne.

## Fictional character biography
### Siobhan McDougal

Siobhan McDougal is the first-born child of Garrett McDougal, the patriarch of an ancient Gaelic clan living on an island between Scotland and Ireland. On that island is Castle Broen, where first-born McDougals undergo a ritual to prove themselves worthy to lead the clan. When Siobhan performs the ritual, she is transported to the netherworld and granted powers by the Crone entity.
Afterwards, Siobhan becomes the villain Silver Banshee and an enemy of Superman. She later joins Alexander Luthor Jr.'s Secret Society of Super Villains in Infinite Crisis.

### Siobhan Smythe

Siobhan Smythe, the second incarnation of Silver Banshee, is introduced in The New 52 continuity reboot. She is an Irish girl who immigrates to the United States to start a new life following her parents' deaths.
In Dawn of DC, Silver Banshee is released from prison and begins dating Jimmy Olsen.

## Powers and abilities

Both incarnations of Silver Banshee possess preternatural levels of strength and resistance to injury powerful enough to prove physically challenging for super-powered Kryptonians like Superman and Supergirl. While not completely invulnerable, they are able to wound Kryptonians to a limited degree when they exert their full strength. While physically powerful, a Banshee's signature weapon is her sonic scream or "death wail". Her cry kills anyone who hears it, provided she knows their full name, reducing them to desiccated husks as the scream drains their life-force to strengthen the Banshee, akin to a succubus or psychic vampire.
As Siobhan Smythe of The New 52 continuity, Silver Banshee has exhibited an affinity for "omnilingualism" - able to instinctively speak any language fluently from the first moment she hears it, including being able to commune with animals.
