Sean Sonus was a drug dealer who killed Tina Boland's boyfriend and partner Vincent Sobel on the night the S.T.A.R. Labs particle accelerator exploded. Sonus was gifted with metahuman powers, being able to sonically-induce vertigo in people. Sonus traveled across the country, while Boland desired revenge. Finally tracking Sonus down in Hub City, Boland reluctantly teamed up with the Green Arrow, Curtis Holt, and Wild Dog. At a gang gathering, Sonus' powers were dampened and he was killed by Tina.
