Winchell was the CEO of the Shimano Industries.
Winchell hired Inque to sabotage a new satellite launch for insurance fraud. When she came to collect her reward, Winchell blasted her with a particle destabilizer/disintegration ray, damaging her integrity. Batman later infiltrated his office to collect information on Inque, but Winchell caught him and called for his security force. Batman easily escaped and captured Winchell. He then interrogated the corrupt businessman while dangling him over the edge of a building, successfully getting the information he wanted.
