Captain W. Wyndam is a character from the Streets of Rage comic.
Wyndam is the current chief of police in the city, and much like most of the cops in the city he's also corrupt, receiving money from the organized crime to ignore their business.
He first appears having an argument with Max Thunder and Blaze Fielding, who turn their badges. Shortly after he calls Hawk, alerting him that the two had resigned and would go after him. After Hawk is killed and his base destroyed, Wyndam attempts to arrest Max and Blaze and berates Axel Stone, who punches him before resigning from the police force as well.
