Check out promo and new photos for the upcoming episode of SMALLVILLE "Escape" Season 9 Episode 15 which airs on Friday April 2 at 8 p.m. on The CW.
The above photo features a character called Siobhan aka Silver Banshee. If we can believe Wikipedia, her powers are pretty cool:
Silver Banshee has superhuman strength, agility, speed, endurance, a high degree of resistance to physical and energy attacks. Her wail can kill anyone within a certain range as long as she can see her victim and knows their true name. Victims are usually reduced to desiccated husks. Silver Banshee is able to use her sonic powers to teleport.
