Shawna Guzman

Shawna Guzman, self-styled Shockwave, is a superhuman criminal from Centre City. After Kane's particle accelerator incident, Shawna gained the power to create fierce, and devastating shockwaves. Shawna was in the middle of a crime spree until being attacked by Lightspeed. Upon defeating him, she began to threaten CCPD until finally attacking the police, with Lightspeed's phasing ability being the key to Shawna's downfall.

During Shadow's raid on Ultimate City, Shawna was freed from the Vault. However, she was eventually caught and arrested again.
