Big Sir (Dufus Ratchett) is a fictional DC Comics character. He first appeared in The Flash #338 (October 1984).

Big Sir appears in the fourth season of The Flash, portrayed by Bill Goldberg.

Ratchett was born with a malformed brain gland that caused him to grow to incredible proportions but left him mentally handicapped. After the Rogues capture him and give him high-tech armor created by the Monitor, he becomes Big Sir and comes into conflict with the Flash. After being defeated, he is brought to Gorilla City and has his mind repaired.

Big Sir's mind later inexplicably returns to its previous state, and he joins the Injustice League, led by Major Disaster. The League later briefly becomes Justice League Antarctica before their base is destroyed in a battle with flesh-eating penguins. Afterwards, he is fired by Maxwell Lord, but given financial compensation.^{[1][2][3][4][5]}

Big Sir later joins the Suicide Squad in return for a pardon, along with most of his Injustice League friends. They are sent to battle a mad scientist, during which Big Sir is killed by a genetically engineered creature resembling a child.^[6]

Due to his size, Big Sir possesses physical power greater than that of a normal human being. He has an electronic flail that emits energy and enables him to fly via propulsion.

Big Sir appears in The Flash, portrayed by Bill Goldberg.^[7] This version is David P. Ratchett, an inmate of Iron Heights Penitentiary nicknamed "Big Sir" with normal intelligence and no powers who was indebted to Henry Allen before saving his son Barry from the other inmates. After discovering that Ratchett was framed by Sylbert Rundine, Barry works to free him before transporting him to Jiaju, China.
