Echo

Golden Age Origin
Jim Carson was both a professional ventriloquist and amateur detective. He fights crime by throwing his voice. His assistants include his wife Cora and his chemist brother, Dr. Doom. Besides his ventriloquism, Echo uses an invisibility belt and later a radioactive ring which allows him to fire paralyzing beams from his eyes.
