Roshanna Chatterji (also known as Tremor) is a superhero in the DC Universe with the ability to create vibrations, giving her the power to create earthquakes or disrupt land. Tremor is Bengali and was born in India, where she discovered her ability to move the earth with shockwaves. She frequently displayed her powers, which led to people calling her a witch. She moved to the U.S., where she quickly made new friends, before an alcohol-fueled joyride changed her life. Tremor was created by Gail Simone and Jim Calafiore and first appeared in the Secret Six comics. She also appears within the rebooted Prime Earth (or the New 52) continuity, in The Movement comic book series. Tremor, a teenager, is asexual, making her the only known asexual superhero in either DC Comics or Marvel.
